The antenna trimmer works fine. The first stage of RF filtering works well
across
all the bands. The antenna trimmer obviously helps here as it is just a cap
in parallel
with the tuning cap. My problems seem to be coming from either the RF
after, or the
following tuned circuits/switches.

Did have a damaged primary coil on one of the input transformers though,
T16. It was fried.
I wound 2 turns and this fixed it.

Does the antenna trimmer work properly? That is, do you get a sharp
peak in the response when it is adjusted? If the antenna trimmer works
across the band, then the antenna coil is OK. My HQ-180 had a broken
wire in the cable coming from the trimmer cap.
