Transmit Receive Antenna Switching

Circuit Schematic

Front Face

Back Face.

Kind of obvious how it all works, pulling the BNC to ground changes over the amp relays from receive to transmit. 12v to the antenna relays to turn on the appropriate antenna port.

I will be controlling the antenna ports from a micro controller that is also changing over relays on the low pass filter board, which is also what I intend on building next.
