Bob speaks the truth here. The K6XX fast relay circuit is the answer. The problem with Elecraft rigs switching Ameritron amps has existed with the K2/100 and, so it appears, now with the K3/100. I have had the K6XX fast relay circuit in my AL-1200 working with the K2/100's. No KPA-100 shutdowns since I put it in a couple of years ago. And there has been no problem with the K3/100. It is a simple fix to allow the K2/100 & K3/100 to work with the slower 12VDC Ameritron amp relays ..... if you need it. 73 Hank K8DD
Roger Go to this site http://www.k6xx.com/radio/fastrely.pdf K6XX has a need relay speed-up circuit that might be applicable to the relay in your amp. I suppose that it requires the relay to be a 12v relay, though. Don't know what you actually have. Good luck and 73 Bob N6WG -- View this message in context: http://www.nabble.com/K3-and-linear-amp-tp16180386p16213536.html Sent from the Elecraft mailing list archive at Nabble.com. _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
