[Elecraft] K3 TX-INH

[Stewart Bryant]

Does the TX-INH state over-ride all other TX commands?

I am trying to find a very simple way of preventing the
K3 from transmitting for more than (say) 10 mins when
used remotely.

I can tell if it has gone into transmit by looking at the
KEY-OUT. What I need is a way of unconditionally
killing any transmit, and I am hoping the setting
TX-INH will do that.

Since I use cat TX control, I imagine the only
alternative is to become a man in the middle
of the CAT interface, relaying the RS232 bytes
back and fourth and interjecting an RX command
if I detect the timeout state. This fails my
criteria that failsafes must be so simple
they are obviously bug free.
