I too had David's (k3tue) problem tuning for a peak on 20M and 40M after
completing the base kit. When I tuned the receiver at the end of Part
II, I connected directly to my longwire and was able to easily peak each
band.
For the final tune, I plugged in my longwire via a 4:1 balun. I went
back and fourth too many times trying to peak both bands. Just had a
devil of a time and finally got it the best I could and left it. Had
the feeling that something wasn't right and was afraid I had screwed up
something in the Part III construction.
A couple of days later I took the rig outside to give it a try from the
patio with just a 28 ft wire.
Decided to try tuning it again and both bands peaked right up. Turned
out I had been pretty close.
Decided to get the XG2 to use when I install the 3080. It just came in
the mail so I have a little build to look forward to. I have the 3080
all built, just have to work up the nerve to try installing the thing in
my functioning KX1. Think I'll go back and check the toroids again.
