I got the same advice, but mine were quite tight. If you have

This may not be directly related, but I had power indication problems in
that the SWR and FWD power readings on my K3 had become erratic with surging
of indicated power on CW from a setting of 50W up to 100W and over, yet a
constant tune signal was rock steady at 50W. I thought it was an
I agree, and you'll need pretty high Q components. Lots of good
capacitor choices at HSC. Another suggestion though. KLIV is omni during
the day, but strongly directional at night. This is quite common on the
AM band. I suggest that you make your strength measurements at night.

I would try an L/C series trap at the frequency of your offending BC
band station across your antenna feedline. That should not be dependent
on the IN/OUT impedance requirement of the DX Engineering BC band filter.

Use a series-tuned “wave trap” on KLIV’s frequency across your feedline. That
will short out the feedline at that frequency. It will add some inductive load
above the resonant frequency, but the ATU can deal with that.
The components need to be rated for the transmission line voltages, but they
I have a 160M full length dipole. The center used to be at about
40 feet. About the time version 5.57 of the firmware came out,
the mast supporting the center feed point broke and I re-rigged
with the center at about 22 feet. (I hate debugging when there
were two changes.)
