    I do not think so. Here is what I did and it works! On the Volume 
Control there are little X that you can put over a speaker or a 
microphone and there is a chain looking thing you can leave and both 
levers move together or you can break the chain and they are seperate.

    Now I started to just fool with these things with gMFSK running and 
after beaking a chain it started to work! I saw signals from the radio. 
I wrote down all the settings and even took a picture of the thing. I 
talked back east from NM and it's working fine.

    Thanks for the full-duplex idea! That is what the problem was.
