Appears John G4ZTR has solved the control issue with K3 Inhibit.

I am using Inhibit on 2m and higher with my K3 and thought I would 
share how I did it using a sequencer.  BTW the K3 will not transmit 
RF unless the Inhibit line is keyed by my sequencer even if I use the 
XMIT button in TUNE (this is as it should be so accidental RF is not 
transmitted).  When my sequencer is powered off the K3 cannot be 
keyed on 2m, but will function on other bands.  I accomplished this 
by using the BAND0 control line to enable Inhibit only on 2m (which 
uses TRN1 for my station).  TRN1 outputs +5v on BAND0 which I use for 
driving a relay to enable INHIBIT.  See my webpage:

Disregard references to the FT-847 inhibit.
