[Elecraft] K3s feature request: deadman timer

[brian]

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.
