v0.3.1-alpha
Sideband, Columba, and MeshChat connect via TCP Client Interface on port 4242.
If radio ALC meter is high or power fluctuates, reduce this value.
| RX too low | Increase radio's audio output setting or USB interface input gain |
| RX too high | Decrease radio's audio output setting |
| TX power low | Increase TX Volume above, or increase radio's audio input setting |
| TX power unstable | Decrease TX Volume above (ALC kicking in) |
For USB interfaces (Digirig, SignaLink): use alsamixer -c {{ audio_card if audio_card is not none else 'X' }} via SSH.
For radios with built-in USB audio (IC-7300, IC-705, etc): adjust levels in radio menu.
| DATAC1 | Strong signals, clear channel. Best throughput for local/regional NVIS. |
| DATAC3 | Default choice. Works in moderate noise. Good for unknown conditions. |
| DATAC4 | Weak signals, high noise, long-distance DX. Slowest but most robust. |
Important: All stations must use the same mode to communicate. Coordinate with other operators before changing.

| Low/no TX power | Increase TX Volume slider above, or increase radio's audio input level |
| TX power unstable | Decrease TX Volume slider (ALC is kicking in) |
| RX level too low | Increase radio's audio output level, or use alsamixer to increase input gain |
| Can't connect from phone | Connect to ReticulumHF WiFi, use TCP Client Interface on port 4242 |
| freedvtnc2 won't start | Check rigctld is running first (provides CAT control) |
