[arm-allstar] UV-82 No audio/DTMF input

[Doug Crompton]

Dave,

 In the simpleusb-tune-menu there is a V option. It shows the COS INPUT and
PTT. When selecting that you should see CLEAR for COS INPUT and COS
COMPOSITE when you are not talking TO your node
and KEYED when your are. When someone else is talking you should see KEYED
for PTT and CLEAR otherwise.

If you are seeing proper level in item 2 (RX level) you should also be
seeing the KEYED in the COS INPUT and COS COMPOSITE in the V option. AS was
mentioned you do not use the CTCSS input. Set it to off and only use COS. I
believe for the UV82 it is set to USBINVERT but this depends on the mod.
you made.

This might also be a level issue causing DTMF to not work properly. Go into
the Asterisk client from the menu and key up and press each key and see if
it decodes properly.  The level in item 2 should be set to 5 Khz or a
little above on voice peaks.
