One other way to prevent the K3 from transmitting (it will still key
but with no RF output). Apply 5v to pin-7 of the ACC after
placing TX INH set to HI in the CONFIG menu. Remove the 5v and the
radio will function normally.

shows how to use inhibit on VHF bands but not on HF. A simple
modification could be done where the relay is replaced by a toggle
switch and eliminate the transistor and BAND and DIGOUT
circuitry. The voltage regulator, 1K resistor, and diode are not
needed and can be replaced with a 2.2K to 10K resistor (K3 manual,
page 19) connected to 12v thru a toggle switch.
I just boot my computer before powering up the K3 (I am not using the
LP Bridge).
