Configuration, RRC 1258 / Troubleshooting ptt hardware

« on: 2014-06-24, 15:27:08 »

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,
