So it seems the instructions aren't lacking and not sure how to improve it. I did first and second time make use of the loops, and that worked well in both cases. Second time around I just made everything long perhaps 10cm LOL since I wanted room to play with, plus, I wound 31 turns and 3x3 turns, hoping that may make it work on both 20m and 30m, but it seems to work fine on 30m but there is a horrible loud rapid fire sound as soon as I go above 12.505 MHz. Maybe not related to T1.
It is not T1-related. I think this is something else completely, and is related to the firmware. It was a short-cut I took, while under time-pressure getting it all ready in time for the YOTA summercamp buildathon. We cannot really call it a "bug" since QCX is intended as a single-band rig and everything works fine. But you are taking it a little out of normal usage, and tuning a QCX built for one band, onto another band. Well anyway, I can easily change it in the next firmware version I think!
