New features: - Connection health monitor with live TCP checks for rigctld and modem - RNS interface statistics display (TX/RX byte counts per interface) - PWA support (installable app with service worker for offline caching) - Auto-configure ALSA levels when Digirig/CM108 is plugged in (udev rule) - CM108 GPIO PTT detection for hardware PTT support - Added Kenwood TS-890S radio configuration Bug fixes: - Copy buttons now work over HTTP (not just HTTPS) - CLI commands section shows correct audio card number New endpoints: - /api/rigctld-health - TCP health check with frequency display - /api/rns-stats - Parsed interface statistics from rnstatus

# ReticulumHF: Set ALSA audio levels for digital modes
|
|
#
|
|
# Called by udev when CM108/Digirig USB audio device is plugged in.
|
|
# Also can be run manually: ./set-digirig-audio.sh <card_number>
|
|
#
|
|
# Sets optimal defaults for FreeDV digital modes:
|
|
# - Speaker (TX output): 80%
|
|
# - Mic Capture (RX input): 75%
|
|
# - Mic Playback (monitoring): Muted
|
|
# - Auto Gain Control: Off
