[Elecraft] K3s feature request: deadman timer

[Jim Miller]

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.

Thanks for your consideration
