Hi Jim,
Upon more review, I decided to add a patch to try to completely turn off
DTMF decode, if desired. So, I added some test code to the chan_usbaudio.c
file and a new boolean parameter "dtmf_decode" to the usbradio.conf file.
With dtmf_decode=0, the audio dropout issue is completely resolved! Now,
the staticy HF audio sounds GREAT (to me, at least!). No more
choppiness...
I'll be glad to post the patch if you all would like to take a look? It
doesn't seem to break anything (so far....).
Thanks for your help!
73, David KB4FXC
