Thanks again to everyone who replied to my call for help. Bob - AG5Q led me on the right path. Q4 a 2N7000 on the Controller board was the culprit. As soon as it was replaced I had immediate joy. My problem was in not looking at anything other than the RF board. Merry Xmas to all, and to all a Good Nite. 73, Bob Abell ARRL, RAC, NJQRP , K2's 2062 & 2676
