I would be very interested in seeing the patch!  I am impressed with the
solution!  Good job!

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

decoded. If you are running as a remote base node, then no DTMF functions
will be decoded fromt he radio interface. Remote base nodes have .y on the
end of them in the node table. This is how app_rpt knows which type of code
to run.
