Topband: [Bulk] BCB interference ?

[Grant Saviers]

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.
