[arm-allstar] New HAM need help with DTMF

[David McGough]

Hi Ken,

I, personally, haven't encounted any cheap HT's where DTMF failed to 
decode with radio relax off--at least if they'd decode at all on any 
system! Almost every case I've seen where DTMF didn't decode could be 
corrected by careful audio level adjustment at the channel driver end.

The problem with leaving radio relax enabled is that there will be very, 
very many false decodes and the cooresponding 20ms audio chop. That gets 
really annoying (to me, at least).
