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

[Dave Perkins]

Hi guys,

Using USBINVERT....CTCSSFORM is off and all PL settings are correct 
on both node radio and HT used to talk to node. Even tried a 
different HT and same problem.

There is a little success though. In simple_tune, I turned RX boost 
off and now on CLI, I am able to see DTMF being entered. Before, with 
RX boost enabled I was not even though my RX levels were in spec.

Even though the DTMF is being decoded via CLI, I am still not able to 
connect to any nodes or even get a read back using *70 using the DTMF 
keypad. At least CLI is now decoding the DTMF.

I will play around with it more when I get back in a couple of days 
and report anything else I find.

Any other suggestions or ideas are always much appreciated.

Thanks
Dave KC6ZBE
