If we were to inject a sub-sonic or super-sonic "sidetone"

That ought to work.

This AGC issue is yet another example of loss of audio knowhow at the
manufacturers, Sony did an excellent overmodulation protection circuit
on their 510 portable r2r and then promptly forgot all about it.

I'd got for a subsonic tone myself.

A firmware hack is described on a web site linked to somewhere in the
thread, the minimum required change might however be just to lengthen
the release time.
