[Elecraft] K2 Push To Talk

[Don Wilhelm]

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.
