Thanks for the feature request! We'll discuss at the next meeting and update here if we come to a decision on whether this will be implemented.

Thanks! I realize it’s not critical, but it would be a good “someday” feature if anyone is working on that part of the code.

I have this idea running in Linux as a stand alone program which interacts with pipewire to record the FreeDV decoded audio to a file with the callsign of the station being recorded along with the date. The GUI is as below with entry box for the callsign start and stop and 'Recording' indicator. The saved files may be replayed over the air by selecting them using the voice keyer. Reports from other stations listening to the replayed files are very surprised at how accurate the recovered audio is after two encodes and decodes compared to the station heard direct.
File names are like: freedv_rec_G1INU_20251215_130925.wav
If the .wav is converted to .mp3 the file size can be made suitable for emailing without any noticeable degredation.
I have found it very useful for demonstrating audio issues to new users on the air.

If a similar feature were to be built into FreeDV this would be a useful addition. The GUI could be more compact.

Created PR #1145 implementing this feature. Let me know if this works for you.
