OK, here were my symtoms: Just completed Assembly Part II. Performing the VCO alignment... all is well (all voltages well in range)until I get to the 10m band. The Low freq. reading is 3.046... ok so far. But as I tune towards 28,800 I lose lock at about 28,400 or so.... voltage ramps up to 8.4.
I checked C71 - C74, D21-D26, T5. all are correct. Soldering looks good. I move the windings of T5 in and out... this just changes the freq I lose lock at, but not by much. Still can't get near 28,800. I rewind T5... just for the fun of it.... (?) NO help there either. I e-mail Gary at Elecraft (3:01pm) Get a reply from Gary (4:33pm) He gave me a PAGE worth of "might be"... one being to check RCF15. He said if it was open it can cause all sorts of odd problems. Well, it WAS open... I must have bent the leads to much or heated it too much, or whatever. Anyway, I bridged across it momentarily to see what effect it would have. Guess what? ALL VCO voltages were well within limits...including 10m high freq. Without even touching L30. So, I ordered a new choke and thanked Gary for a quick and accurate response. My comment to him was: "What a great radio, what a great staff...." It don't get better than this....... Now, back to building the best radio on the market.... by the way, I was able to copy a little CW on 40m while setting up to adjust the IF amp... Thanks Elecraft for a great product and a GREAT staff.
