[Elecraft] Feature request - Disable Break In on K3

Interesting discussion.  I use KEY-OUT to control my sequencer so my 
mic or KEY function just like they do on HF.  I utilize  INH to 
prevent RF until the proper time in sequence of change over from Rx to Tx.

BUT, I do not do very much CW on VHF+ with my KEY.  Most CW is 
computer "keyboard" generated so the sw generates a RTS command over 
RS232 to Key the K3 PTT.  This is definitely semi break-in, where the 
radio is held in Tx as long as CW characters are running in the 
computer buffer.

This will be an issue if I send CW manually.  Looks to me adding a 
manual PTT switch which keys PTT on the K3 would be the solution 
(could be a foot switch or toggle switch on the control panel).  I 
assume I would not need to switch off VOX as the PTT input would 
overide the VOX.  Is that true?

I try to configure my station to work nearly automatically when I 
change over from HF to VHF+ so mistakes do not happen.  Thanks to the 
originator of this quesion.
