Another solution for this, at least for CW, is to get a WinKeyerUSB.
Those have two outputs, a PTT and a Key line. There is a variable,
programmable, delay between when PTT is activated and when the Key
line becomes active.
I use the PTT to key my amp and 30 mS later key the K2. The delay can
be made very long, up to at least 990 mS, in 10 mS increments.

Lloyd,
If you don't like my fix for this situation, you can use a footswitch
to activate your amp and switch your preamp off-line before hitting
the paddles - just don't make any mistakes and get things in the wrong
order.
I have not seen anything comparable to my solution. It was intended
specifically for those using VHF gear with the K2.

Has anyone come up with a simple fix to add an external PTT line to
the K2?
I recently picked up a used K2 and just completed building a 222
transverter. I didn't realize that the K2 does not have a
Transmit/Receive
switch. So, I will be hot switching, in CW mode. WSJT is not a
problem as
there is a built in delay between when PTT and audio is outputted.
An external sequencer won't help as I can't get control of the K2
PTT line
in CW mode.
Any ideas besides W3FPR's fix?
