Using K3/0 or K3/Mini to connect to remote K3 over RRCs, started getting ERR PTT from the remote K3 on startup, indicating PTT was asserted on the remote K3 when it was attempting to power up.
Found that disconnected Control RRC from the K3 Mic jack avoided the error (checked both by removing mic jack connection and disconnecting RJ45 from the RRC - it is not a cable issue) - so, the Control RRC is asserting PTT on that connection.
On the control RRC page, PTT Status says off, but that does not seem to be the case.
Tried remote reset, had local guy unplug power to the control RRC, tried soft reset with the button on the back panel - no joy, the problem remains.
Anything else to try besides hard reset on the remote button? If that (and restoring everything) doesn't solve the problem, anything other than a hardware fault possible?
Thanks, John K3TN
