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.
