Some months back I posted this problem with my KPA100 (http://www.ac6rm.net/mailarchive/html/elecraft-list/2004-05/msg00106.html), and never got any suggestioons which fixed the problem.
After a little fiddling I'd figured it was a lack of isolation through the PIN switch in the KPA100 on receive, but then ran out of time / urgency to work any more on it. However - it needed fixing before taking the radio to 5U5Z for CQWW and just at that time I saw the posting from Mike suggesting adding the low value capacitor to shunt the capacitive leakage through the diodes. Worked just fine for me too. Incidently - those of you who worked 5U5Z this weekend past in CQWW CW on 40 - 10m worked another set of K2/100s. We would have had a K2/100 on 80 as well except for a noisy 12V PSU, so one K2 stayed as a spare. The 4 K2s made around 14000 QSOs in that 48 hour period! All the radios equitted themselves really well and it's great that you can fit a competitive 100W station into a carry on size backpack, including the logging computer & a spare set of tubes for one of the amplifiers! Certainly makes dealing with the current excess baggage obsessions of airlines easier! 73, Andy, G4PIQ _______________________________________________ Elecraft mailing list Post to: [email protected] You must be a subscriber to post to the list.
