- Added timeout for PTT; if audio device fails to play audio due to sample rate mismatch, it will timeout and unkey the PTT
- Added device removal detection. If the audio device is removed/unplugged while the Audio Modem is running, it will detect this and stop the connection
- Audio Modem now locates devices by name instead of ID. Many USB audio devices change their ID when plugged and unplugged.
- Fixed a bug where the search bar was expecting uppercase callsigns. It should now be case insensitive #99
- Search bar now supports a fallback address search. If the text is not a callsign or a coordinate, it will do a regular address search
