Observation: My K3 stops transmitting after 30 seconds of dashes already. (Makes it tough curing an RFI issue single handed...)
So it appears to have a "stuck key" deadman of sorts. Haven't checked whether it does that in other transmit conditions. Obviously, it doesn't in JT65, PSK, SSTV. 73 de Brian/K3KO On 6/4/2017 20:55 PM, Jim Miller wrote:
In reviewing what I need to do to remote my K-Line a good solution to a hung transmitter has remained elusive. The only sure way to kill the transmitter is by pulling the plug, potentially scrambling the firmware. Note that sending commands from an attached PC is not a solution since it may have been the culprit in the hang in the first place. Likewise internet access may have been disrupted making remote reset impossible. I believe the solution is best solved by putting a deadman timer option in the K3 firmware. I envision this as having an adjustable period (0-99) of minutes, zero would be the default and make the deadman timer off. The deadman timer would be reset each Key out went inactive. I'm not sure what the K3 should do other than cease transmitting. It may be best to do a full orderly shutdown. That way external logic could sense via the Aux connector Pin8 (Power On) or the RCA 12v DC out jack that the K3 is off and take station specific action.
