Bill, I beleive you are asking about an Amp Keying line for the basic K2 -- Take a look at the AMP keying partial kit from Elecraft and also look at Tom Hammond's website www.n0ss.net for an updated version - I believe Elecraft will be adopting Tom's improved Amp Keying circuit for the K2, but I don't know that with any degree of certainty - I am not an 'insider' for such Elecraft business decisions. I do know that Tom's circuit works FB.
OTOH, if you are asking about a CW 'PTT' input to the K2 to interrupt keying until an external PTT signal is present, take a look at my website http://w3fpr.qrpradio.com article on CW PTT for the K2. This circuit will prevent keying the K2 until an 'OK to transmit' signal is received from a sequencer or footswitch - works great for the VHF crowd that needs to delay the RF output until all switching is ready for RF or for those who have amplifiers with slow T/R switching. 73, Don W3FPR > -----Original Message----- > > Anybody have any good ideas about where to connect to the K2 > circuitry to pick off a PTT low keying line.
