I would to know of a way to confirm the ptt hardware is working or not. I have a set of 1258 RemoteRigs and I can receive just fine. I am using a Kenwood TS480. When I key the control head with a microphone the system stays in receive mode and ignores the fact that I have pushed the ptt button on the microphone. When I set the jumpers originally I was confused by the instructions and connected them incorrectly. Now I believe they are correct but transmitting does not work. I would like a process to put a voltmeter on specific pins when I key the mic to determine if I have damaged the RemoteRig or not.
Thank you,
