[Elecraft] L1 & L2 Alignment Problem

Yes, it checked out just fine at that stage.  I even listened to several SW stations -- good audio and good sensitivity.

Yes, I did every check up to this point and everything was OK.  I did have to -- at the instruction of Elecraft staff -- put in a "gimmick cap" to get the Low BFO freq within range.  Had to bring it down a tad.

I have checked these, and I'll check them again.  Everything seems to look OK.  Thanks, Don, for your help.   Any other ideas?
