Just wanted to let all of the folks assisting me with this problem, what i found. Yes the problem appeared to be somthing not right with Q1 on the ssb brd. After replcing Q1,Q2,Q3, and a dozen or so associated components, i started tracing signals. When sigs at ALC threshold on U2 (Max 522) didn't match the sig on emitter of Q1, i noticed that this signal gets routed from the top of the brd down to the bottem of the brd thru an empty thru-hole plated hole. When i soldered that empty thru hole full of solder, i got this problem to go away. Apparently the thru -hole plating had an intermittent connection. This explains why it would somtimes work with the brd just plugged in (not screwed down) es the when tightened down, quit working. ( flex on the brd opened the ckt) It would seem that the thru hole plating on this particular ckt brd was not up to par, or had opened up during shipping. So this problem is fixed. Now ive got other problems. Don't think they are related. Power out put drops off seriosly on 20 15 es 10 meters 20, max pwr out = 5 w. 15 = 1 w. 10 = less than 1 watt. May just be improper alignment. I'll let you know what i find. Suggestions wellcome. I'd like to agn thank all of the fine people on this reflector for all ur help. The caliber of support for Elecraft products is exceptional, and i have confidence that this rig will be playing as it should very soon.
