[Elecraft] Use of config Tx Inh pin 7 of ACC K3s

[Rich - K1HTV]

Howard,
  On my K3 I had to tie TX Inh (ACC pin 7) to +12V via a 2K resistor for the inhibit function to work correctly with my VHF/UHF sequencer. I used the +12V from the sequencer power supply, but you could use the +12V available at the RCA connector on the back of the radio to supply the necessary voltage. GL.

I am trying to use the Tx Inh (pin 7 of ACC) to allow the K3 to xmit only
when my 2M EME sequencer allows. In testing out this function, I find that
when Inh Hi or Lo is used, once you apply a logic change to pin 7 the Tx
Inh will lock in the on position. Removing the logic signal, or returning
to Rx leaves this function not active to allow for Tx. So Tx inh works fie
but for only ONE time? I can re state the Tx Inh only if I go to config and
cycle througe the states again.

Am I not understanding the function of Tx Inh, or is there a problem in the
K3 internal logic?

Thanks,
