[arm-allstar] Kenwood TH-D74A DTMF issue

[James R. Pilgram]

SSH into your node, Try from the main menu option 12. Then toggle Option 
G. Reset audio level settings in Option 2. I like to use the IaxRpt 
client to do the settings with. Once you have it set so it's not too low 
or running off the scale, Go back to the CLI prompt and watch the screen 
as you toggle all the DTMF buttons. You may find you might have to 
toggle B RX Boost on or off and reset the levels on Menu item 2 in the 
"tune-menu" again depending on what node radio you are using. That' s 
how I do it. Maybe someone has a better way?

However, your NFM test tells me that you should be able to reduce your receive input level with the SimpleUSB/USBRadio menu and it might make it work better for plan FM. I'm going to give that a try.
