[Elecraft] External linear amplifier with CW

Hi 'crafters, I perused the archives and found a little bit of information on the K2 having a high voltage keying transistor for keying an external amplifier. Use of 8R Hold for delay times? I need more help on how to do this for operating in CW only. I am accustomed to linears having

Thanks for the tips. The K2 PA Keyout line to the Tokyo Hy-Power Send input works perfectly for putting the linear amp into transmit mode. I set the T-R delay to .75 for a good delay time when sending slow code. Thanks for all the replies. 73, Joe, aa4nn K2VCO Wrote: You shouldn't have any

Re: [Elecraft] External linear amplifier with CW

I have the circuit from the Elecraft web site. Unfortunately, my SB-220 won't really do QSK. Any ideas on how to modify the little perf board interface to put some (hopefully adjustable) delay in the release to simulate semi-QSK with VOX for the amp? 73, Fred K6DGW Auburn CA CM98lw Vic
