[amsat-bb] ICOM 9700 RF Issue?

[Tony]

Jerry:

I believe it does have the latest firmware. The Main CPU version reads 
1.24. I disabled the mast mounted pre-amps thinking that might be the 
issue but the problem remains. There is no pop when I disconnect the 2 
meter antenna from the radio and transmit on 70cm.

73, Tony
