 Why not use GPDMA to transfer samples through SGPIO?
-^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 It would be great if we could, as that would free up lots of processor time. Unfortunately, the GPDMA scheme in the LPC43xx does not seem to support peripheral-to-memory and memory-to-peripheral transfers with the SGPIO peripheral.

-HackRF One produces a 10 MHz clock signal on CLKOUT. The signal is a 3.3 V, 10 MHz square wave intended for a high impedance load.
+HackRF Pro
+~~~~~~~~~~
 
-The CLKIN port on HackRF One is a high impedance input that expects 3.3 V square wave at 10 MHz. Do not exceed 3.3 V or drop below 0 V on this input. Do not connect a clock signal at a frequency other than 10 MHz (unless you modify the firmware to support this). You may directly connect the CLKOUT port of one HackRF One to the CLKIN port of another HackRF One.
+HackRF Pro has two configurable SMA ports, P1 and P2. By default, P1 is configured as CLKIN and P2 as CLKOUT. The default behaviour of these signals is as described for HackRF One below.
+
+A second CLKIN signal is available on header P22 pin 2. Unlike HackRF One, HackRF Pro's P22_CLKIN is a separate signal from P1_CLKIN. To enable P22_CLKIN instead of P1_CLKIN use ``hackrf_clock -c p22``.
+
+Various internal signals can be connected to P1 or P2 instead of the default CLKIN and CLKOUT signals. Use ``hackrf_clock -1`` or ``hackrf_clock -2`` to select a different signal.

Do not connect a clock signal at a frequency other than 10 MHz (unless you modify the firmware to support this). You may directly connect the CLKOUT port of one HackRF One to the CLKIN port of another HackRF.
+
+The CLKIN signal is also connected to header P22 pin 2. Unlike HackRF Pro, HackRF One has only one CLKIN signal shared between P22 pin 2 and the CLKIN port. Do not connect input signals to both CLKIN and P22 pin 2 simultaneously.
 
 HackRF One uses CLKIN instead of the internal crystal when a clock signal is detected on CLKIN. The switch to or from CLKIN only happens when a transmit or receive operation begins.

-FAQ
-================================================
-
-
-What is the Transmit Power of HackRF?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-HackRF One's absolute maximum TX power varies by operating frequency:
-
-    * 1 MHz to 10 MHz: 5 dBm to 15 dBm, generally increasing as frequency increases (see this `blog post <https://greatscottgadgets.com/2015/05-15-hackrf-one-at-1-mhz/>`__)
-    * 10 MHz to 2150 MHz: 5 dBm to 15 dBm, generally decreasing as frequency increases
-    * 2150 MHz to 2750 MHz: 13 dBm to 15 dBm
-    * 2750 MHz to 4000 MHz: 0 dBm to 5 dBm, decreasing as frequency increases
-    * 4000 MHz to 6000 MHz: -10 dBm to 0 dBm, generally decreasing as frequency increases
-
-Through most of the frequency range up to 4 GHz, the maximum TX power is between 0 and 10 dBm. The frequency range with best performance is 2150 MHz to 2750 MHz.
-
-Overall, the output power is enough to perform over-the-air experiments at close range or to drive an external amplifier. If you connect an external amplifier, you should also use an external bandpass filter for your operating frequency.
-
-Before you transmit, know your laws. HackRF One has not been tested for compliance with regulations governing transmission of radio signals. You are responsible for using your HackRF One legally.
-
-
-----
-
-
-What is the Receive Power of HackRF?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The maximum RX power of HackRF One is -5 dBm. Exceeding -5 dBm can result in permanent damage!
-
-In theory, HackRF One can safely accept up to 10 dBm with the front-end RX amplifier disabled. However, a simple software or user error could enable the amplifier, resulting in permanent damage. It is better to use an external attenuator than to risk damage.

-
-What is the minimum signal power level that can be detected by HackRF?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-This isn't a question that can be answered for a general purpose SDR platform such as HackRF. Any answer would be very specific to a particular application. For example, an answerable question might be: What is the minimum power level in dBm of modulation M at frequency F that can be detected by HackRF One with software S under configuration C at a bit error rate of no more than E%? Changing any of those variables (M, F, S, C, or E) would change the answer to the question. Even a seemingly minor software update might result in a significantly different answer. To learn the exact answer for a specific application, you would have to measure it yourself.
-
-HackRF's concrete specifications include operating frequency range, maximum sample rate, and dynamic range in bits. These specifications can be used to roughly determine the suitability of HackRF for a given application. Testing is required to finely measure performance in an application. Performance can typically be enhanced significantly by selecting an appropriate antenna, external amplifier, and/or external filter for the application.

-
-Is HackRF full-duplex?
-~~~~~~~~~~~~~~~~~~~~~~
-
-HackRF One is a half-duplex transceiver. This means that it can transmit or receive but not both at the same time.
-
-
-----
-
-
-Why isn't HackRF One full-duplex?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-HackRF One is designed to support the widest possible range of SDR applications in a single, low cost, portable device. Many applications do not require full-duplex operation. Full-duplex support would have made HackRF larger and more expensive, and it would have required an external power supply. Since full-duplex needs can be met by simply using a second HackRF One, it made sense to keep the device small, portable, and low cost for everyone who does not require full-duplex operation.
-
-
-----
-
-
-How could the HackRF One design be changed to make it full-duplex?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The HackRF One hardware design is actually full-duplex (at lower sample rates) from the USB connection through the ADC/DAC. The RF section is the only part of the design that cannot support full-duplex operation. The easiest way to make HackRF One full-duplex would be to create an add-on board that duplicates the RF section and also provides an external power input (from a wall wart, for example) for the additional power required. This would also require software effort; the firmware, CPLD, libhackrf, and other host software would all need work to support full-duplex operation.
-
-If you were to try to redesign the RF section on HackRF One to support full-duplex, the main thing to focus on would be the MAX2837 (intermediate frequency transceiver). This part is half-duplex, so you would either need two of them or you would have to redesign the RF section to use something other than the MAX2837, likely resulting in a radically different design. If you used two MAX2837s you might be able to use one RFFC5071 instead of two RFFC5072s.
-
-
-----
-
-
-Are those connectors SMA or RP-SMA?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Some connectors that appear to be SMA are actually RP-SMA. If you connect an RP-SMA antenna to HackRF One, it will seem to connect snugly but won't function at all because neither the male nor female side has a center pin. RP-SMA connectors are most common on 2.4 GHz antennas and are popular on Wi-Fi equipment. Adapters are available.

-.. _bigspike:
-
-What is the big spike in the center of my received spectrum?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-If you see a large spike in the center of your FFT display regardless of the frequenecy you are tuned to, you are seeing a DC offset (or component or bias). The term "DC" comes from "Direct Current" in electronics. It is the unchanging aspect of a signal as opposed to the "alternating" part of the signal (AC) that changes over time. Take, for example, the signal represented by the digital sequence:
-
-.. code-block:: sh
-
-	-2, -1, 1, 6, 8, 9, 8, 6, 1, -1, -2, -1, 1, 6, 8, 9, 8, 6, 1, -1, -2, -1, 1, 6, 8, 9, 8, 6, 1, -1
-
-This periodic signal contains a strong sinusoidal component spanning from -2 to 9. If you were to plot the spectrum of this signal, you would see one spike at the frequency of this sinusoid and a second spike at 0 Hz (DC). If the signal spanned from values -2 to 2 (centered around zero), there would be no DC offset. Since it is centered around 3.5 (the number midway between -2 and 9), there is a DC component.
-
-Samples produced by HackRF are measurements of radio waveforms, but the measurement method is prone to a DC bias introduced by HackRF. It's an artifact of the measurement system, not an indication of a received radio signal. DC offset is not unique to HackRF; it is common to all quadrature sampling systems.
-
-There was a bug in the HackRF firmware (through release 2013.06.1) that made the DC offset worse than it should have been. In the worst cases, certain Jawbreakers experienced a DC offset that drifted to a great extreme over several seconds of operation. This bug has been fixed. The fix reduces DC offset but does not do away with it entirely. It is something you have to live with when using any quadrature sampling system like HackRF.
-
-A high DC offset is also one of a few symptoms that can be caused by a software version mismatch. A common problem is that people run an old version of gr-osmosdr with newer firmware.
-
-
-----
-
-
-What gain controls are provided by HackRF?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-HackRF (both Jawbreaker and One) provides three different analog gain controls on RX and two on TX.
-
-The three RX gain controls are at these stages:
-
-- RF ("amp", 0 or 14 dB)
-- IF ("lna", 0 to 40 dB in 8 dB steps)
-- baseband ("vga", 0 to 62 dB in 2 dB steps)
- 
-The two TX gain controls are at these stages:
-
-- RF (0 or 14 dB)
-- IF (0 to 47 dB in 1 dB steps)
-
-
-----
-
-
-Why is the RF gain setting restricted to two values?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-HackRF has two RF amplifiers close to the antenna port, one for TX and one for RX. These amplifiers have two settings: on or off. In the off state, the amps are completely bypassed. They nominally provide 14 dB of gain when on, but the actual amount of gain varies by frequency. In general, expect less gain at higher frequencies. For fine control of gain, use the IF and/or baseband gain options.
-
-
-----
-
-
-Why are the LEDs on HackRF different colours?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-Each LED is a single color. There are no multi-colored LEDs on HackRF One. Adjacent LEDs are different colors in order to make them easier to distinguish from one another. The colors do not mean anything.
-
-
-----

-Where can I purchase HackRF?

+================================================
+Gateware
+================================================
+
+One of the significant hardware changes in :ref:`HackRF Pro <hackrf_pro>` is the replacement of the CPLD with a FPGA. While the older CPLD primarily provided glue logic between the MCU and RF front end, the FPGA in HackRF Pro introduces more logic and DSP capability. This enables offloading digital signal processing tasks from the MCU.
+
+FPGAs are highly flexible devices whose behavior is defined by *gateware*: hardware descriptions that configure the internal logic fabric. HackRF Pro gateware is written in `Amaranth HDL <https://amaranth-lang.org/>`__, a Python-based hardware description language.
+
+The specific FPGA device used in HackRF Pro is the Lattice iCE40UP5K, which features 
+5280 LUT4s and 8 dedicated DSP (multiply-accumulate) blocks. We rely on the `open-source iCE40 FPGA toolchain <https://github.com/YosysHQ/icestorm>`__ to build the required bitstreams that are bundled in the firmware.
+
+All gateware source code lives under `firmware/fpga/` in the HackRF repository. Top-level designs reside in `firmware/fpga/top/` and are the primary entry points for different operational modes.
+
+By default, a standard gateware configuration is loaded at boot. However, the firmware can dynamically reconfigure the FPGA at runtime to switch between different gateware variants.
+
+
+Standard gateware
+~~~~~~~~~~~~~~~~~
+
+The standard gateware is used by default when the firmware has not requested an alternative bitstream.
+
+The standard gateware provides a balanced configuration optimized for general-purpose operation. It implements configurable digital signal processing paths for the reception and transmission paths, capable of (limited) frequency translation and supporting a wide range of sample rates.

+* Double data rate (DDR) interface to RF transceiver
+* Interface to MCU (SGPIO)
+
+
+Half-precision gateware
+~~~~~~~~~~~~~~~~~~~~~~~
+
+The half-precision gateware reduces sample width to 4 bits per I/Q component, enabling higher throughput within the constraints of the USB interface (up to 40 Msps).
+
+This configuration is intended for applications where bandwidth is more critical than dynamic range, such as wideband spectrum monitoring.

+* Transmitter signal chain:

+* SPI control interface for register configuration
+* Double data rate (DDR) interface to RF transceiver
+* Interface to MCU (SGPIO)
+
+Extended-precision gateware (RX and TX)
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The extended-precision gateware increases internal signal processing precision and output sample width to improve signal quality. The main drawback is that the minimum decimation or interpolation factor is 16x. Due to increased logic requirements, this gateware is split in two top-level designs (RX and TX).
+
+Samples are 16-bit I/Q, while the effective number of bits (ENOB) depends on the selected configuration and typically ranges between 9 and 11 bits.
+
+The increased dynamic range of the output makes it particularly useful for weak and/or narrowband signals.

-================================================
-Getting Started with HackRF and GNU Radio
-================================================
-
-We recommend getting started by watching the `Software Defined Radio with HackRF <https://greatscottgadgets.com/sdr/>`__ video series. This series will introduce you to HackRF One, software including GNU Radio, and teach you the fundamentals of Digital Signal Processing (DSP) needed to take full advantage of the power of Software Defined Radio (SDR). Additional helpful information follows.
-
-.. _try_pentoo:
-
-Try Your HackRF with Pentoo Linux
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The easiest way to get started with your HackRF and ensure that it works is to use Pentoo, a Linux distribution with full support for HackRF and GNU Radio. Download the latest Pentoo .iso image from one of the mirrors listed at `http://pentoo.ch/downloads/ <https://pentoo.ch/downloads>`__. Then burn the .iso to a DVD or use `UNetbootin <http://unetbootin.sourceforge.net/>`__ to install the .iso on a USB flash drive. Boot your computer using the DVD or USB flash drive to run Pentoo. Do this natively, not in a virtual machine. (Unfortunately high speed USB operation invariably fails when people try to run HackRF from a virtual machine.)
-
-Once Pentoo is running, you can immediately use it to :ref:`update firmware <updating_firmware>` on your HackRF or use other HackRF command line tools. For a walkthrough, watch `SDR with HackRF, Lesson 5: HackRF One <http://greatscottgadgets.com/sdr/5/>`__.
-
-To verify that your HackRF is detected, type ``hackrf_info`` at the command line. It should produce a few lines of output including "Found HackRF board." The 3V3, 1V8, RF, and USB LEDs should all be illuminated and are various colors.
-
-You can type ``startx`` at the command line to launch a desktop environment. Accept the "default config" in the first dialog box. The desktop environment is useful for GNU Radio Companion and other graphical applications but is not required for basic operations such as firmware updates.
-
-Now you can use programs such as gnuradio-companion or gqrx to start experimenting with your HackRF. Try the Examples below. If you are new to GNU Radio, an excellent place to start is with the `SDR with HackRF <http://greatscottgadgets.com/sdr/>`__ video series or with the `GNU Radio guided tutorials <https://wiki.gnuradio.org/index.php/Tutorials>`__.
-
-**Alternative: GNU Radio Live SDR Environment**
-
-The `GNU Radio Live SDR Environment <https://wiki.gnuradio.org/index.php/GNU_Radio_Live_SDR_Environment>`__ is another nice bootable Linux .iso with support for HackRF and, of course, GNU Radio.
-
-Software Setup
-~~~~~~~~~~~~~~
-
-As mentioned above, the best way to get started with HackRF is to use Pentoo Linux. Eventually you may want to install software to use HackRF with your favorite operating system.
-
-If your package manager includes the most recent release of libhackrf and gr-osmosdr, then use it to install those packages in addition to GNU Radio. Otherwise, the recommended way to install these tools is by using `PyBOMBS <https://github.com/gnuradio/pybombs>`__.
-
-See the :ref:`Operating System Tips <operating_system_tips>` page for information on setting up HackRF software on particular Operating Systems and Linux distributions.
-
-If you have any trouble, make sure that things work when booted to Pentoo. This will allow you to easily determine if your problem is being caused by hardware or software, and it will give you a way to see how the software is supposed to function.
-
-Examples
-~~~~~~~~
-
-A great way to get started with HackRF is the `SDR with HackRF <http://greatscottgadgets.com/sdr/>`__ video series. Additional examples follow:
-
-Testing the HackRF
-
-   #.  Plug in the HackRF
-   #.  run the hackrf_info command ``$ hackrf_info``
-
-If everything is OK, you should see something similar to the following:
-
-.. code-block:: sh
-
-    hackrf_info version: 2017.02.1
-    libhackrf version: 2017.02.1 (0.5)

-    Index: 0
-    Serial number: 0000000000000000################
-    Board ID Number: 2 (HackRF One)
-    Firmware Version: 2017.02.1 (API:1.02)
-    Part ID Number: 0x######## 0x########

+
+There is no specific minimum CPU requirement for the host computer when using a HackRF, but SDR is generally a CPU-intensive application. If you have a slower CPU, you may be unable to run certain SDR software or you may only be able to operate at lower sample rates.

+Maximum input power
+~~~~~~~~~~~~~~~~~~~
+
+The maximum input power of HackRF One is -5 dBm. Exceeding -5 dBm can result in permanent damage!
+
+In theory, HackRF One can safely accept up to 10 dBm with the front-end RX amplifier disabled. However, a simple software or user error could enable the amplifier, resulting in permanent damage. It is better to use an external attenuator than to risk damage.
+
+
+Minimum detectable input power
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This isn't a question that can be answered for a general purpose SDR platform such as HackRF. Any answer would be very specific to a particular application. For example, an answerable question might be: What is the minimum power level in dBm of modulation M at frequency F that can be detected by HackRF One with software S under configuration C at a bit error rate of no more than E%? Changing any of those variables (M, F, S, C, or E) would change the answer to the question. Even a seemingly minor software update might result in a significantly different answer. To learn the exact answer for a specific application, you would have to measure it yourself.
+
+HackRF's concrete specifications include operating frequency range, maximum sample rate, and dynamic range in bits. These specifications can be used to roughly determine the suitability of HackRF for a given application. Testing is required to finely measure performance in an application. Performance can typically be enhanced significantly by selecting an appropriate antenna, external amplifier, and/or external filter for the application.
+
+
+Typical maximum transmit power
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+HackRF One's maximum TX power varies by operating frequency:
+
+    * 1 MHz to 10 MHz: 5 dBm to 15 dBm, generally increasing as frequency increases (see this `blog post <https://greatscottgadgets.com/2015/05-15-hackrf-one-at-1-mhz/>`__)
+    * 10 MHz to 2170 MHz: 5 dBm to 15 dBm, generally decreasing as frequency increases
+    * 2170 MHz to 2740 MHz: 13 dBm to 15 dBm
+    * 2740 MHz to 4000 MHz: 0 dBm to 5 dBm, decreasing as frequency increases
+    * 4000 MHz to 6000 MHz: -10 dBm to 0 dBm, generally decreasing as frequency increases
+
+Through most of the frequency range up to 4 GHz, the maximum TX power is between 0 and 10 dBm. The frequency range with best performance is 2170 MHz to 2740 MHz.
+
+Overall, the output power is enough to perform over-the-air experiments at close range or to drive an external amplifier. If you connect an external amplifier, you should also use an external bandpass filter for your operating frequency.
+
+Before you transmit, know your laws. HackRF One has not been tested for compliance with regulations governing transmission of radio signals. You are responsible for using your HackRF One legally.

 Hardware Triggering
 ===================
 
-HackRF One transmit and receive operations can be synchronized with another HackRF One or with other external equipment by using the trigger input and output on pin header P28. Triggering provides time synchronization with error of less than one sample period.
+HackRF transmit and receive operations can be synchronized with another HackRF or with other external equipment by using the trigger input and output. Triggering provides time synchronization with error of less than one sample period.
 
+HackRF Pro has two configurable SMA ports, P1 and P2, which can be set up to provide both clock synchronization and triggering.
+
+HackRF One has CLKIN and CLKOUT ports for clock synchronization, but hardware triggering requires opening the case to access the P28 header.
 
 Clock Synchronization
 ~~~~~~~~~~~~~~~~~~~~~
 
-When triggering one HackRF One from another, it is often desirable to first ensure that the two devices share a common frequency reference. This has an added benefit of grounding the HackRFs to each other, eliminating one of the wires required for triggering. See :ref:`External Clock Interface <external_clock_interface>` for instructions.

This has an added benefit of grounding the HackRFs to each other, eliminating one of the wires required for triggering. See :ref:`External Clock Interface <external_clock_interface>` for instructions.

+Either HackRF may serve as the clock source for the other regardless of which is providing the trigger output.
+
+Usage
+~~~~~
+
+Use ``hackrf_info`` to discover the serial numbers of both HackRFs. Using the serial number of the HackRF to be triggered, use ``hackrf_transfer -H`` to set up a triggered operation. For example:
+
+* ``hackrf_transfer -H -d <serial number> -a 0 -l 32 -g 32 -r rx1.cs8``
+
+The command will print "Waiting for trigger..." until a trigger signal is detected on the device's trigger input.
+
+In another terminal, use the serial number of the triggering HackRF One to initiate an operation to take place at the same time as the triggered operation. For example:
+
+* ``hackrf_transfer -d <serial number> -a 0 -l 32 -g 32 -r rx2.cs8``
+
+Note that no special argument is required to activate the trigger output.
+
+Both ``hackrf_transfer`` commands will start sampling RF signals at the same time, accurate to less than one sample period.
 
 
-Requirements
-~~~~~~~~~~~~
+Additional Devices
+~~~~~~~~~~~~~~~~~~
+
+Multiple HackRFs may be triggered by a single HackRF. Ensure that all the devices share a common ground and then connect one device's trigger output to the trigger inputs of the other devices (with jumpers connected via a breadboard, for example).
+
+Equipment other than a HackRF may be connected to a HackRF's trigger input or output. The trigger signal is a 3.3 V pulse that triggers on the rising edge.
+
+HackRF One Triggering Requirements
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
 To connect two HackRF Ones for triggering you will need:
 
     * a male-to-male jumper wire for 0.1" pin headers
     * an SMA cable for clock synchronization or a second jumper wire

-
-Both ``hackrf_transfer`` commands will start sampling RF signals at the same time, accurate to less than one sample period.
-
-
-Additional Devices
-~~~~~~~~~~~~~~~~~~
-
-Multiple HackRF Ones may be triggered by a single HackRF One. Ensure that all the devices share a common ground and then connect one device's trigger output to the trigger inputs of the other devices (with jumpers connected via a breadboard, for example).
-
-Equipment other than a HackRF One may be connected to a HackRF One's trigger input or output. The trigger signal is a 3.3 V pulse that triggers on the rising edge.

-Set your Jawbreaker Free!
-~~~~~~~~~~~~~~~~~~~~~~~~~
+Hardware Documentation
+~~~~~~~~~~~~~~~~~~~~~~
 
-Jawbreaker has an SMA antenna connector but also includes a built-in PCB antenna intended for operation near 900 MHz. It isn't a very good antenna. Seriously. A paperclip stuck into the SMA connector would probably be better. You can free your Jawbreaker to operate with better antennas by cutting the PCB trace to the PCB antenna with a knife. This enables the SMA connector to be used without interference from the PCB antenna.
-
-A video that demonstrates the antenna modification is on YouTube: `HackRF Antenna Modification <http://youtu.be/B2gwgNoqMxI>`__
-
-The trace to be cut is between the two solder pads inside a box labeled R44 in the `assembly diagram <https://github.com/mossmann/hackrf/blob/master/doc/hardware/jawbreaker-assembly.pdf?raw=true>`__. There is an arrow pointing to it printed on the board.
-
-Due to a manufacturing error, there is solder on R44. R44 may appear as a single solder blob. If you have a soldering iron and solder wick/braid, use a soldering iron and fine solder wick to remove as much solder as you can from the two R44 pads. Then, use a pen knife to gently cut away the area between the two R44 pads. Make multiple, gentle cuts, instead of one or two forceful cuts. As you cut, you'll break through the black solder mask, then the copper trace between the pads, and stop when you reach fiberglass. Remove the copper trace completely, so just the two R44 pads remain. Use a multimeter or continuity tester to verify that the two R44 pads are no longer connected.
-
-If you don't have a soldering iron, you can cut through the copper trace and the solder blob all at once, but it requires a bit more effort.
-
-The only reason not to do this is if you want to try Jawbreaker but don't have any antenna with an SMA connector (or adapter).
-
-If you want to restore the PCB antenna for some reason, you can install a 10 nF capacitor or a 0 ohm resistor on the R44 pads or you may be able to simply create a solder bridge.
-
-
-
-SMA, not RP-SMA
-~~~~~~~~~~~~~~~
-
-Some connectors that appear to be SMA are actually RP-SMA. If you connect an RP-SMA antenna to Jawbreaker, it will seem to connect snugly but won't function at all because neither the male nor female side has a center pin. RP-SMA connectors are most common on 2.4 GHz antennas and are popular on Wi-Fi equipment.

 Transmit Power
 ~~~~~~~~~~~~~~
 
-The maximum TX power varies by operating frequency:
+The maximum TX power for Jawbreaker varies by operating frequency:
 
     * 30 MHz to 100 MHz: 5 dBm to 15 dBm, increasing as frequency decreases
     * 100 MHz to 2300 MHz: 0 dBm to 10 dBm, increasing as frequency decreases
-    * 2300 MHz to 2700 MHz: 10 dBm to 15 dBm
+    * 2170 MHz to 2740 MHz: 10 dBm to 15 dBm
     * 2700 MHz to 4000 MHz: -5 dBm to 5 dBm, increasing as frequency decreases
     * 4000 MHz to 6000 MHz: -15 dBm to 0 dBm, increasing as frequency decreases
 
 Overall, the output power is enough to perform over-the-air experiments at close range or to drive an external amplifier. If you connect an external amplifier, you should also use an external bandpass filter for your operating frequency.
 
-Before you transmit, know your laws. Jawbreaker has not been tested for compliance with regulations governing transmission of radio signals. You are responsible for using your Jawbreaker legally.

-
-Transceiver Mode
-^^^^^^^^^^^^^^^^
-
-HackRF can operate in four main transceiver modes: Receive, Transmit, Signal Source, and Sweep. There is also a CPLD update mode which is used to write firmware images to the CPLD flash.
-
-The transceiver mode can be changed with ``hackrf_set_transceiver_mode`` with the value parameter set to one of the following:
-
-.. code-block:: sh
-
-	enum transceiver_mode_t {
-		HACKRF_TRANSCEIVER_MODE_OFF = 0,
-		HACKRF_TRANSCEIVER_MODE_RECEIVE = 1,

-		HACKRF_TRANSCEIVER_MODE_SS = 3,
-		TRANSCEIVER_MODE_CPLD_UPDATE = 4,
-		TRANSCEIVER_MODE_RX_SWEEP = 5,
-	};
-
-Receive mode (TRANSCEIVER_MODE_RX) is used to stream samples from the radio to the host system. Use ``hackrf_set_freq`` to set the center frequency of receiver and ``hackrf_set_sample_rate`` to set the sample rate (effective bandwidth).
-
-Transmit mode (TRANSCEIVER_MODE_TX) is used to stream samples from the host to the radio.
-
-See `hackrf_transfer <https://github.com/mossmann/hackrf/blob/master/host/hackrf-tools/src/hackrf_transfer.c>`__ for an example of setting transmit and receive mode and transferring data over USB.

   :alt: Opera Cake 
 
 Opera Cake is an antenna switching add-on board for HackRF One. Consisting of two 1x4 switches, Opera Cake also has a cross-over switch that permits operation as a 1x8 switch. Up to eight Opera Cakes may be stacked onto a single HackRF One provided that each Opera Cake is configured with a different board address.
 
+Opera Cake can be used as a 1x8 switch to connect your HackRF One to a variety of antennas at once, such as a long wire antenna for HF bands, a discone for VHF and UHF, a dipole for 2.4 GHz, and a dish for a satellite band. Once connected to your Opera Cake you can switch between all of your antennas in software instead of making physical hardware swaps.
+
+When set up as a pair of 1x4 switches you could use Opera Cake as a switched filter bank. To do this, connect port A1 to B1, A2 to B2, A3 to B3, and A4 to B4 through physical SMA filters and cables of your choosing. This setup allows you to change your transmit or receive to be through the filter of your choosing without having to reconnect hardware every time you would like to use a different filter.
+
 Opera Cake is configured with the ``hackrf_operacake`` command-line tool.
-
-
-Using Opera Cake
-~~~~~~~~~~~~~~~~
-
-Banks
-^^^^^
-
-Opera Cake's ports are grouped in two banks (or "sides"), one on each end of the board. Bank A consists of ports A0 through A4 while bank B consists of ports B0 through B4.
-
-Ports
-^^^^^
-
-Opera Cake has two primary ports, A0 and B0, each of which can be switched to any of eight secondary ports, A1-A4 and B1-B4. Each primary port is always connected to one secondary port. By default, A0 is connected to A1, and B0 is connected to B1. It is not possible to connect both primary ports to secondary ports in the same bank at the same time.
-
-Port connections may be configured manually. For example, to connect A0 to A2 and B0 to B3:
-
-.. code-block:: sh
-
-    hackrf_operacake -a A2 -b B3
-
-To connect A0 to B2 and B0 to A4:
-
-.. code-block:: sh
-
-    hackrf_operacake -a B2 -b A4
-
-If only one primary port is configured, the other primary port will be connected to the first secondary port on the opposite side. For example, after the next two commands B0 will be connected to A1:
-
-.. code-block:: sh
-
-	hackrf_operacake -a A2 -b B3
-	hackrf_operacake -a B2
-
-LEDs
-^^^^
-
-Port selections are indicated by LEDs next to each port's connector. Port A0 and the secondary port connected to A0 are indicated with a green LED. Port B0 and the secondary port connected to B0 are indicated with a yellow LED.
-
-Board Address
-^^^^^^^^^^^^^
-
-Each Opera Cake has a numeric address set by optional jumpers installed on header P1. The default address (without jumpers) is 0. The ``--list`` or ``-l`` option can be used to list the address(es) of one or more Opera Cakes installed on a HackRF One:
-
-.. code-block:: sh
-
-	hackrf_operacake -l
-
-The address may be set to any number from 0 to 7 by installing jumpers across the A0, A1, and/or A2 pins of header P1.
-
-.. list-table::
-  :header-rows: 1
-  :widths: 1 1 1 1
-
-  * - Address
-    - A2 Jumper
-    - A1 Jumper
-    - A0 Jumper

-
-When configuring an Opera Cake, the address may be specified with the ``--address`` or ``-o`` option:
-
-.. code-block:: sh
-
-	hackrf_operacake -o 1 -a A1 -b B2
-
-If the address is unspecified, 0 is assumed. It is only necessary to specify the address if the address has been changed with the addition of jumpers, typically required only if multiple Opera Cakes are stacked onto a single HackRF One.
-
- 
-Modes of Operation
-~~~~~~~~~~~~~~~~~~
-
-Opera Cake supports three modes of operation: ``manual``, ``frequency``, and ``time``. The operating mode can be set with the ``--mode`` or ``-m`` option, and the active operating mode is displayed with the ``--list`` or ``-l`` option.
-
-Manual Mode
-^^^^^^^^^^^
-
-The default mode of operation is ``manual``. In manual mode, fixed port connections are configured with the ``-a`` and ``-b`` options as in the port configuration examples above. If the operating mode has been changed, it can be changed back to manual mode with:
-
-.. code-block:: sh
-
-	hackrf_operacake -m manual
-
-Frequency Mode
-^^^^^^^^^^^^^^
-
-In frequency mode, the A0 port connection switches automatically whenever the HackRF is tuned to a different frequency. This is useful when antennas for different frequency bands are connected to various ports.
-
-The bands are specified in priority order. The final band specified will be used for frequencies not covered by the other bands specified.
-
-To assign frequency bands to ports you must use the ``-f <port:min:max>`` option for each band, with the minimum and maximum frequencies specified in MHz. For example, to use port A1 for 100 MHz to 600 MHz, A3 for 600 MHz to 1200 MHz, and B2 for 0 MHz to 4 GHz:
-
-.. code-block:: sh
-
-	hackrf_operacake -m frequency -f A1:100:600 -f A3:600:1200 -f B2:0:4000
-
-If tuning to precisely 600 MHz, A1 will be used as it is listed first. Tuning to any frequency over 4 GHz will use B2 as it is the last listed and therefore the default port.
-
-Only the A0 port connection is specified in frequency mode. Whenever the A0 connection is switched, the B0 connection is also switched to the secondary port mirroring A0's secondary port. For example, when A0 switches to B2, B0 is switched to A2.
-
-Once configured, an Opera Cake will remain in frequency mode until the mode is reconfigured or until the HackRF One is reset. You can pre-configure the Opera Cake in frequency mode, and the automatic switching will continue to work while using other software.
-
-Although multiple Opera Cakes on a single HackRF One may be set to frequency mode at the same time, they share a single switching plan. This can be useful, for example, for a filter bank consisting of eight filters.
-
-Time Mode
-^^^^^^^^^
-
-In time mode, the A0 port connection switches automatically over time, counted in units of the sample period. This is useful for experimentation with pseudo-doppler direction finding.
-
-To cycle through four ports, one port every 1000 samples:
-
-.. code-block:: none
-
-	hackrf_operacake -m time -t A1:1000 -t A2:1000 -t A3:1000 -t A4:1000
-
-When the duration on multiple ports is the same, the ``-w`` option can be used to set the default dwell time:
-
-.. code-block:: none
-
-	hackrf_operacake --mode time -w 1000 -t A1 -t A2 -t A3 -t A4
-
-Only the A0 port connection is specified in time mode. Whenever the A0 connection is switched, the B0 connection is switched to the secondary port mirroring A0's secondary port. For example, when A0 switches to B2, B0 is switched to A2.
-
-Once configured, an Opera Cake will remain in time mode until the mode is reconfigured or until the HackRF One is reset. You can pre-configure the Opera Cake in time mode, and the automatic switching will continue to work while using other software.
-
-Although multiple Opera Cakes on a single HackRF One may be set to time mode at the same time, they share a single switching plan.

+Once configured, an Opera Cake will remain in time mode until the mode is reconfigured or until the HackRF One is reset. You can pre-configure the Opera Cake in time mode, and the automatic switching will continue to work while using other software.
+
+Although multiple Opera Cakes on a single HackRF One may be set to time mode at the same time, they share a single switching plan.

 RF Shield Installation Instructions
 ===============================================
 
+HackRF Pro ships with an RF shield as standard.
+
 Official Great Scott Gadgets HackRF Ones do not come from the factory with an RF shield installed around the radio section of the PCB. They do, however, have pads in place so that one may be installed if a user has a reason and an inclination to do so. The reason that they do not come preinstalled is that early testing revealed that the RF shield did little to improve the performance of the HackRF One. The recommended RF shield is the BMI-S-230-F-R (frame) with the BMI-S-230-C (shield). A two part RF shield is recommended because the shield section can be removed to allow access to the RF section of the HackRF One. This can be important if it becomes necessary to probe any part of the RF section, or to replace any parts of the RF section. However, even with a two part RF shield, it can be difficult to access the RF section of the HackRF One in certain situations. The following steps are a basic set of instructions for installing a RF shield on a HackRF One.
 
 **CAUTION: Soldering a RF shield onto a HackRF One comes with a certain amount of risk. Beyond the inherent risks of soldering itself, this process may damage the HackRF One and no warranty is available to cover damage incurred from this process. If you do choose to install a RF shield on your HackRF One please proceed with caution.**

+Sampling Rate and Baseband Filters
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Using a sampling rate of less than 8MHz is not recommended. Partly, this is because the MAX5864 (ADC/DAC chip) isn't specified to operate at less than 8MHz, and therefore, no promises are made by Maxim about how it performs. But more importantly, the baseband filter in the MAX2837 has a minimum bandwidth of 1.75MHz. It can't provide enough filtering at 2MHz sampling rate to remove substantial signal energy in adjacent spectrum (more than +/-1MHz from the tuned frequency). The MAX2837 datasheet suggests that at +/-1MHz, the filter provides only 4dB attenuation, and at +/-2MHz (where a signal would alias right into the center of your 2MHz spectrum), it attenuates about 33dB. That's significant. Here's a picture:
+
+.. image:: ../images/max2837-1m75bw-at-2m.png
+	:align: center
+
+At 8MHz sampling rate, and using the minimum 1.75MHz bandwidth filter, this is the response:
+
+.. image:: ../images/max2837-1m75bw-at-8m.png
+	:align: center
+
+You can see that the attenuation is more than 60dB at +/-2.8MHz, which is more than sufficient to remove significant adjacent spectrum interference before the ADC digitizes the baseband. If using this configuration to get a 2MHz sampling rate, use a GNU Radio block after the 8MHz source that performs a 4:1 decimation with a decently sharp low pass filter (complex filter with a cut-off of <1MHz).

+============================
+Setting Gain Controls for RX
+============================
+
+Gain controls
+~~~~~~~~~~~~~
+
+HackRF One provides three different analog gain controls on RX and two on TX.
+
+The three RX gain controls are at these stages:
+
+- RF ("amp", 0 or ~11 dB)
+- IF ("lna", 0 to 40 dB in 8 dB steps)
+- baseband ("vga", 0 to 62 dB in 2 dB steps)
+ 
+The two TX gain controls are at these stages:
+
+- RF (0 or ~11 dB)
+- IF (0 to 47 dB in 1 dB steps)
+
+Note: in some documents, the RF gain was erroneously quoted to be 14 dB. The confusion was based on the fact that the MGA-81563 amplifier is advertised as a "14 dBm" amplifier, but that specifies its output power, not its amplification. See `Martin Ling's comment on issue #1059 <https://github.com/greatscottgadgets/hackrf/issues/1059#issuecomment-1060038293>`__ for some details!
+
+The TX and RX RF amplifiers have two settings: on or off. In the off state, the amps are completely bypassed. They nominally provide around 11 dB of gain when on, but the actual amount of gain varies by frequency. In general, expect less gain at higher frequencies. For fine control of gain, use the IF and/or baseband gain options.
+
+A good default setting to start with is RF=0 (off), IF=16, baseband=16. Increase or decrease the IF and baseband gain controls roughly equally to find the best settings for your situation. Turn on the RF amp if you need help picking up weak signals. If your gain settings are too low, your signal may be buried in the noise. If one or more of your gain settings is too high, you may see distortion (look for unexpected frequencies that pop up when you increase the gain) or the noise floor may be amplified more than your signal is.

-In addition to third party tools that support HackRF, we provide some commandline tools for interacting with HackRF. For information on how to use each tool look at the help information provided (e.g. ``hackrf_transfer -h``) or the `manual pages <http://manpages.ubuntu.com/manpages/utopic/man1/hackrf_info.1.html>`__.
+Many of these tools require libhackrf and at times HackRF Tools. It may help you to have updated libhackrf and HackRF Tools when troubleshooting these applications. 
 
-The first two tools (``hackrf_info`` and ``hackrf_transfer``) should cover most usage. The remaining tools are provided for debugging and general interest; beware, they have the potential to damage HackRF if used incorrectly.
-
-    * **hackrf_info** Read device information from HackRF such as serial number and firmware version.
-
-    * **hackrf_transfer** Send and receive signals using HackRF. Input/output can be 8bit signed quadrature files or wav files.
-
-    * **hackrf_max2837** Read and write registers in the Maxim 2837 transceiver chip. For most tx/rx purposes hackrf_transfer or other tools will take care of this for you.
-
-    * **hackrf_rffc5071** Read and write registers in the RFFC5071 mixer chip. As above, this is for curiosity or debugging only, most tools will take care of these settings automatically.
-
-    * **hackrf_si5351c** Read and write registers in the Silicon Labs Si5351C clock generator chip. This should also be unnecessary for most operation.
-
-    * **hackrf_spiflash** A tool to write new firmware to HackRF. This is mostly used for :ref:`Updating Firmware <updating_firmware>`.
-
-    * **hackrf_cpldjtag** A tool to update the CPLD on HackRF. This is needed only when :ref:`Updating Firmware <updating_firmware>` to a version prior to 2021.03.1.

+.. _synchronization_checklist:
+
+================================================
+Synchronization Checklist
+================================================
+
+There are many scenarios where you may want to use multiple HackRF One devices
+synchronized with each other. For instance, multiple devices can be used with a
+phased antenna array to implement direction finding or beamforming.
+
+If you're having trouble achieving fully synchronized operation, the following
+checklist may be useful for troubleshooting:
+
+* **Are you running the latest firmware and host software versions?**
+
+    There have been many bug fixes, so please use the latest releases.
+
+* **Are you applying settings to the right target devices?**
+
+    With more than one HackRF device connected, you need to take care to specify
+    which device should be used where. When using our command line tools, use the
+    ``-d`` option with a serial number on the command line to specify which
+    device each command should target.
+
+* **Are all HackRFs sharing a clock?**
+
+    If the HackRFs are not sharing a clock, frequencies and sample rates will
+    not match exactly. See the
+    :ref:`external clock interface <external_clock_interface>`
+    section for how to connect the clock signals.
+
+* **Is the clock input being detected?**
+
+    Use ``hackrf_clock`` with the ``-i`` option to check for clock input.
+    Use the ``-d`` option to specify the serial number.
+
+    This requires ``2022.09.1`` or later host software.
+
+    The older way of checking using ``hackrf_debug`` will not work correctly on
+    some hardware revisions.
+
+* **If the clock source is CLKOUT of another HackRF, has it been enabled?**
+
+    Use ``hackrf_clock`` with the ``-o`` option to enable the clock output.
+    Use the ``-d`` option to specify the serial number.
+
+* **Is the CLKIN waveform correct?**
+
+    * It should be a 10 MHz square wave between 0 V and 3.0 to 3.3 V.
+    * A sine wave is OK, but may give greater phase noise.
+    * An unbuffered TCXO output may not have sufficient voltage.
+    * Some hardware revisions are less tolerant of out-of-spec
+      clock input than others.
+
+* **Is your hardware faulty?**
+
+    Some HackRF clones were sold with a non-functional CLKIN port.
+
+* **Are all HackRFs being started together using hardware triggering?**
+
+    If hardware triggering is not used, start times will not match exactly.
+    See the :ref:`hardware triggering <hardware_triggering>` section for how
+    to connect the necessary trigger signals.
+
+    Use ``hackrf_transfer`` with the ``-H`` option to wait for trigger input.
+
+    If launching multiple ``hackrf_transfer`` instances, make sure that those
+    running with ``-H`` have had time to reach the ``Waiting for trigger...``
+    state before the trigger signal is sent.
+
+    .. note:: There is currently no support for hardware triggering via the
+              Osmocom or Soapy blocks in GNU Radio. The Osmocom block may look
+              like it supports this but the options have no effect. 
+
+* **Are any samples being lost due to USB throughput problems?**
+
+    If RX samples are dropped or TX samples delayed, signals will become out
+    of sync.
+
+    Use ``hackrf_debug -S`` on each HackRF after running your software to check
+    if there were throughput problems. If the shortfall count reported is
+    non-zero, some samples were dropped on RX or late for TX, and signals will
+    be out of sync as a result.
+
+    This requires ``2022.09.1`` or later host software.
+
+    To force shortfalls to stop the device at runtime, use
+    ``hackrf_debug -T 0 -R 0`` to set zero tolerance for shortfalls.
+
+* **Are your HackRFs sharing a USB bus?**
+
+    A single HackRF One at 20 MHz sample rate uses practically all the bandwidth
+    of a single USB 2.0 bus. Unless using very low sample rates, each HackRF
+    should be connected to its own bus.

-USB Cables (and why to use a noise reducing one)
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The USB cable you choose can make a big difference in what you see when using your HackRF and especially when using it around between 120 and 480 MHz where USB is doing all its work.
-
-    #. Use a shielded USB cable. The best way to guarantee RF interference from USB is to use an unshielded cable. You can test that your cable is shielded by using a continuity tester to verify that the shield on one connector has continuity to the shield on the connector at the other end of the cable.
-
-    #. Use a short USB cable. Trying anything larger than a 6ft cable may yield poor results. The longer the cable, the more loss you can expect and when making this post a 15ft cable was tried and the result was the HackRF would only power up half way.
-
-    #. For best results, select a cable with a ferrite core. These cables are usually advertised to be noise reducing and are recognizable from the plastic block towards one end.
-

Partly, this is because the MAX5864 (ADC/DAC chip) isn't specified to operate at less than 8MHz, and therefore, no promises are made by Maxim about how it performs. But more importantly, the baseband filter in the MAX2837 has a minimum bandwidth of 1.75MHz.

 Troubleshooting

+================================================
+
+HackRF not detected / "No HackRF boards found."
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If the software you're using is unable to detect the HackRF hardware and/or `hackrf_info` returns "No HackRF boards found.", this can be caused by a number of different software or hardware issues.
+
+Solution
+--------
+
+    #. If you are using a PortaPack addon, make sure to select "HackRF" mode from the main menu.
+
+    #. If you are using a virtual machine or Windows Subsystem for Linux (WSL), make sure that it is configured to pass through the USB device.
+
+    #. Check whether the device appears in ``lsusb`` (Linux), Device Manager (Windows), or System Report (macOS). If it doesn't not appear, it could either be a firmware issue, an issue with the cable, or another hardware issue.
+
+    #. Try booting the HackRF in DFU mode by holding the "DFU" button when plugging in the device. It should now appear as `NXP Semiconductors LPC4330FET180 [ARM Cortex M4 + M0] (device firmware upgrade mode)` in the locations listed above. If it does appear, then it was likely a firmware issue and you can follow the instructions to :ref:`recover the SPI flash firmware <recovering_firmware>`.
+
+    #. If the device does not appear in DFU mode then it is likely to be an issue with the USB cable. Charge-only cables (which do not include the data lines) have become very common and will cause this symptom. Ideally, test the cable you're using with another device that does some sort of data transfer to be sure that it works, or just try other cables.
+
+    #. If the device still does not appear, it may be a less common issue or possibly a fault with the hardware. See :doc:`Getting Help <getting_help>` for information on where to ask for more support, and please include as much detail as you can about what you've already tried.

+.. _bigspike:
+
+There is a big spike in the center of the received spectrum
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you see a large spike in the center of your FFT display regardless of the frequenecy you are tuned to, you are seeing a DC offset (or component or bias). The term "DC" comes from "Direct Current" in electronics. It is the unchanging aspect of a signal as opposed to the "alternating" part of the signal (AC) that changes over time.

+
+   DC spike
 
 
-How do I deal with the big spike in the middle of my spectrum?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+Take, for example, the signal represented by the digital sequence:
 
-Start by reading :ref:`our FAQ Response on the DC Spike <bigspike>`. After that, there are a few options:
+.. code-block:: sh
+
+	-2, -1, 1, 6, 8, 9, 8, 6, 1, -1, -2, -1, 1, 6, 8, 9, 8, 6, 1, -1, -2, -1, 1, 6, 8, 9, 8, 6, 1, -1
+
+.. figure:: ../images/dc_spike_example_plot.png
+   :align: center
+
+   Example signal
+
+This periodic signal contains a strong sinusoidal component spanning from -2 to 9. If we plot the spectrum of this signal, you can see one spike at the frequency of this sinusoid and a second spike at 0 Hz (DC).
+
+
+.. figure:: ../images/dc_spike_example_spectrum.png
+   :align: center
+
+   Spectrum of example signal
+
+If the signal spanned from values -2 to 2 (centered around zero), there would be no DC offset. Since it is centered around 3.5 (the number midway between -2 and 9), there is a DC component.
+
+Samples produced by HackRF are measurements of radio waveforms, but the measurement method is prone to a DC bias introduced by HackRF. It's an artifact of the measurement system, not an indication of a received radio signal. DC offset is not unique to HackRF; it is common to all quadrature sampling systems.
+
+A high DC offset is also one of a few symptoms that can be caused by a software version mismatch. A common problem is that people run an old version of gr-osmosdr with newer firmware.
+
+Solution
+--------
+
+There are a few options:
 
     #. Ignore it. For many applications it isn't a problem. You'll learn to ignore it.
 
     #. Avoid it. The best way to handle DC offset for most applications is to use offset tuning; instead of tuning to your exact frequency of interest, tune to a nearby frequency so that the entire signal you are interested in is shifted away from 0 Hz but still within the received bandwidth. If your algorithm works best with your signal centered at 0 Hz (many do), you can shift the frequency in the digital domain, moving your signal of interest to 0 Hz and your DC offset away from 0 Hz. HackRF's high maximum sampling rate can be a big help as it allows you to use offset tuning even for relatively wideband signals.
 
     #. Correct it. There are various ways of removing the DC offset in software. However, these techniques may degrade parts of the signal that are close to 0 Hz. It may look better, but that doesn't necessarily mean that it is better from the standpoint of a demodulator algorithm, for example. Still, correcting the DC offset is often a good choice.

-A good default setting to start with is RF=0 (off), IF=16, baseband=16. Increase or decrease the IF and baseband gain controls roughly equally to find the best settings for your situation.

-
-What are the minimum system requirements for using HackRF?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-The most important requirement is that you supply 500 mA at 5 V DC to your HackRF via the USB port. If your host computer has difficulty meeting this requirement, you may need to use a powered USB hub.
-
-Most users will want to stream data to or from the HackRF at high speeds. This requires that the host computer supports Hi-Speed USB. Some Hi-Speed USB hosts are better than others, and you may have multiple host controllers on your computer. If you have difficulty operating your HackRF at high sample rates (10 Msps to 20 Msps), try using a different USB port on your computer. If possible, arrange things so that the HackRF is the only device on the bus.
-
-There is no specific minimum CPU requirement for the host computer, but SDR is generally a CPU-intensive application. If you have a slower CPU, you may be unable to run certain SDR software or you may only be able to operate at lower sample rates.

-
-
-Why isn't HackRF working with my virtual machine (VM)?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-HackRF requires the ability to stream data at very high rates over USB. Unfortunately VM software typically has problems with continuous high speed USB transfers.
-
-There are some known bugs with the HackRF firmware's USB implementation. It is possible that fixing these bugs will improve the ability to operate HackRF with a VM, but there is a very good chance that operation at higher sample rates will still be limited.

-
-What LEDs should be illuminated on the HackRF?
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-When HackRF One is plugged in to a USB host, four LEDs should turn on: 3V3, 1V8, RF, and USB. The 3V3 LED indicates that the primary internal power supply is working properly. The 1V8 and RF LEDs indicate that firmware is running and has switched on additional internal power supplies. The USB LED indicates that the HackRF One is communicating with the host over USB.
-
-The RX and TX LEDs indicate that a receive or transmit operation is currently in progress.

-
-I can't seem to access my HackRF under Linux
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-
-If you run ``hackrf_info`` or any other command which tries to communicate with the HackRF and get one of the following error messages 
-
-.. code-block :: sh
-
-	hackrf_open() failed: HACKRF_ERROR_NOT_FOUND (-5)
-
-or:
-
-.. code-block :: sh
-
-	hackrf_open() failed: HACKRF_ERROR_LIBUSB (-1000)
-
-there are a few steps you can try:
-
-#. Make sure that you are running the latest version of libhackrf and hackrf-tools. HackRF One, for example, is only supported by release 2014.04.1 or newer. Try running ``hackrf_info`` again to see if the updates have addressed your issue.
-
-#. Write a udev rule to instruct udev to set permissions for the device in a way that it can be accessed by any user on the system who is a member of a specific group.
-
-	A normal user under Linux doesn't have the permissions to access arbitrary USB devices because of security reasons. The first solution would be to run every command which tries to access the HackRF as root which is not recommended for daily usage, but at least shows you if your HackRF really works.
-
-	To write a udev rule, you need to create a new rules file in the ``/etc/udev/rules.d`` folder. I called mine ``52-hackrf.rules``. Here is the content:
-
-	.. code-block :: sh
-
-		ATTR{idVendor}=="1d50", ATTR{idProduct}=="604b", SYMLINK+="hackrf-jawbreaker-%k", MODE="660", 	GROUP="plugdev"
-		ATTR{idVendor}=="1d50", ATTR{idProduct}=="6089", SYMLINK+="hackrf-one-%k", MODE="660", GROUP="plugdev"
-		ATTR{idVendor}=="1fc9", ATTR{idProduct}=="000c", SYMLINK+="hackrf-dfu-%k", MODE="660", GROUP="plugdev"
-
-	The content of the file instructs udev to look out for devices with Vendor ID and Product ID matching HackRF devices. It then sets the UNIX permissions to ``660`` and the group to ``plugdev`` and creates a symlink in ``/dev`` to the device.
-
-	After creating the rules file you can either reboot or run the command ``udevadm control --reload-rules`` as root to instruct udev to reload all rule files. After replugging your HackRF board, you should be able to access the device with all utilities as a normal user. If you still can't access the device, make sure that you are a member of the plugdev group.
-
-	(These instructions have been tested on Ubuntu and Gentoo and may need to be adapted to other Linux distributions. In particular, your distro may have a group named something other than plugdev for this purpose.)
-
-#. Disable USB autosuspend for HackRF. A common problem for laptop users could power management enabling USB autosuspend, which is likely if ``hackrf_info`` returns an error of ``hackrf_open() failed: Input/Output Error (-1000)`` on the first execution, and works if you run it a second time directly afterwards. This can be confirmed by running ``LIBUSB_DEBUG=3 hackrf_info`` and checking that the error is a ``broken pipe``. \
-
-	If you use the TLP power manager you can add the HackRF USB VID/PIDs to the ``USB_BLACKLIST`` line in ``/etc/default/tlp`` (under Archlinux create a file ``/etc/tlp.d/10-usb-blacklist.conf``, under Ubuntu the config file can be found at ``/etc/tlp.conf``):
-
-	.. code-block:: sh
-
-		USB_BLACKLIST="1d50:604b 1d50:6089 1d50:cc15 1fc9:000c"
-
-	and restart TLP using ``tlp restart`` or ``systemctl restart tlp``.
-

-
-
-The command hackrf_info failed with "hackrf_open() .. HACKRF_ERROR_NOT_FOUND"
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-
-This could be a problem of a kernel driver. Some ubuntu versions, like Ubuntu 15.04 with installed gnuradio has a kernel driver pre-installed. In this case you probably will get some syslog kernel messages like:
-
-    * kernel: [ 8932.297074] hackrf 1-9.4:1.0: Board ID: 02
-    * kernel: [ 8932.297076] hackrf 1-9.4:1.0: Firmware version: 2014.08.1
-    * kernel: [ 8932.297261] hackrf 1-9.4:1.0: Registered as swradio0
-    * kernel: [ 8932.297262] hackrf 1-9.4:1.0: SDR API is still slightly experimental and functionality changes may follow
-
-when you plug in the the HackRF module. Use the command ``dmesg`` to check the last system log entries. If you try to start ``hackrf_info`` it will terminate with the error message and the system log will show a message like:
-
-    * kernel: [ 8967.263268] usb 1-9.4: usbfs: interface 0 claimed by hackrf while 'hackrf_info' sets config #1
-
-To solve this issue check under root account if is there is a kernel module ``hackrf`` loaded: ``lsmod | grep hackrf``. If there is a hackrf kernel module, try to unload it with ``rmmod hackrf``. You must do this command as root, too. After this the command ``hackrf_info`` (and all other hackrf related stuff) should work and the syslog usbfs massage should vanish.
-
-After a reset or USB unplug/plug this kernel module will load again and block the access again. To solve this you have to blacklist the hackrf kernel module in /etc/modprobe.d/blacklist(.conf) The current filename of the blacklist file may differ, it depends on the current ubuntu version. In ubuntu 15.04 it is located in /etc/modprobe.d/blacklist.conf. Open this file under root account with a text editor an add the following line at the end:
-
-.. code-block:: sh
-
-	blacklist hackrf
-
-After a system-restart, to get the updated modprobe working, the hackrf worked under ubuntu 15.04 with the upstream packages (Firmware version: 2014.08.1) out-of-the-box.

+The USB cable you choose can make a big difference in what you see when using your HackRF and especially when using it around between 120 and 480 MHz where USB is doing all its work.
+
+    #. Use a shielded USB cable. The best way to guarantee RF interference from USB is to use an unshielded cable.
