No, but FWIW, I'm having problems playing back what I record. After a
seemingly random amount of time into playing the recording, the audio
cuts out, but sometimes TX stays on for some additional seconds.
Sometimes TX drops while the audio is playing. There doesn't seem to
be any pattern to it, but I haven't been able to get it to go all the
way through a full 15 second recording.

I'm having similar problems playing back recorded RX audio - it'll play
the first two or three seconds, then cut out, but the timer keeps
counting.
