Be able to delete any recorded audio, without turning off the radio

It must be recorded as an audio file. Maybe Flex would divulge that information. Or, maybe it's recorded in the radio, then that is a whole different story.

Perhaps a work-around would be to quickly double click the record button.

There are other recorder functions I'd like:

• Indication of how much is recorded in the buffer (time, kB, etc)
• Export / import of audio to PC (wav, mp3 formats?)
• Simple editing controls (playback a selection, eg.)?
  

There's a limit to what you can do in a tiny amount of screen real estate, without bringing up a new window.  Ability to export/import allows you to edit offline if you really care. FRS has said that's somewhere on their to-do list.

It would be helpful to have a little block diagram that shows where in the "audio chain" the recording happens and where the playback is inserted  (relative to gain, eq, processor settings etc.).  Is the recorded signal, except for gain, the same as the MON output?
