In San Jose, CA I had a 50kw station on 1Mhz unobstructed line of sight
3 miles from my 80m vertical, and had good success with this 100w
capable filter, used all HF bands for several years and no problems.

I was measuring some other BP filters with my VNWA and measured the
following for the Heros HS-BCB0200007 I have
Flat -0.25db 1.8MHz to 37MHz; -25db @ 1.525MHz; -55db or better below
1.35MHz.
-25db @ 1.525MHz will help reduce overload if that is the problem, but
you may need a custom notch filter.

Has anyone used this High Pass Filter ?

I found I have a 25KW AM 1520 Khz BC transmitter 12 miles from me ,
is that close enough to interfere with me receiving weak signal DX on
the top Band ? I do hear some wide band hash 1837 to 1840 !
Though I would asking before placing an order, not sure how what to
look for with BCB interference ?
Tnx Ed N5DG
