[Elecraft] K2 Push To Talk

[Lloyd Korb]

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?
