Installing 2 comms and looking for DIY switch/wiring diagram (poors mans audio panel) Will be using 2 separate ant.
Thank you
 
Dual radios

I did this on my RV4. Also have two vhf antennas. I used the ptt to activate a a multiple pole relay. Radio audio was disabled on the unkeyed radio to prevent noise from keyed transmiter. Only have spdt toggle on panel. Was designed on the back of envelope if you don't find something I'll try to find it.
 
I used a DPDT and switched PTT and Mic Hi. Been working great for over 25 years.

I did this and added a third pole. This lets the "COMM FREQ FLIP/FLOP" button on the stick flip the frequencies for the radio that is active.
