Check the listing for details. Dorsett Electronics TR-501 Phase Modulated Transmitter 231.9MHz Ham Radio Tested. Condition: Used. Listed at 85.00 USD. The SMA connector was bent, I straightened it (which would be a problem at higher frequencies but not a problem at UHF) and installed an extender so there is a clean connection to the output. I marked the circuit connections on the outside, A=no connection, B = power, C=ground, D=signal, E=signal ground (both grounds connect to chassis).
