If I read the documentation correctly, the echoUAT can either get squawk code, altitude and Ident by sniffing power to old transponder or from a modern EFIS unit.
Also says to keep its antenna at least one meter from any existing transponder antenna.
This makes me wonder if either of these are possible:
1) Put a dummy load on my GTX 320A and replace its antenna with the one supplied with the echoUAT.
2) Remove the GTX 320A and its AK-350 altitude encoder and make my own control head (simulating a modern EFIS). (I have altitude info from Dynon D-10A.)
Am I missing something? Do you still need a Mode C transponder in addition to the UAT transmitter?
Why?
Two different frequencies?
