Yes, thank you Olli. The only problem being that if both stations try to TX
then none of them will.

Hi Igor,
you may want to check this very simple circuit:

Subject: [Elecraft] K3 lock out via Inhibit
Yet again I need to organize lock out for a pair of K3s. Therefore
couple of questions for those who knows how to do it.
1)The manual says one need 2.2 to 10k pull up resistor on pin 7 of the
ACC connector from 5V source. There is no 5V source in ACC connector (BTW
Elecraft could easily provide one either on pin 12 or pin 5. Both of them
are now used for GROUND). The easy answer to the problem is to use 12V
out RCA socket on the back panel. Is it necessary to step down that 12V
to 5V or it is safe enough to connect say 20K pull up resistor from 12V
to pin 7 ?
2) Is it OK to use Keyout-Lp from pin 10 of one radio to Inh pin 7 of the
other radio and vise versa. What I am concerned about is what happen if
on one of the rigs someone unintentionally switch the setting of pin 7
from Inh to K3 ON?
