Topband: Hi Pass Filter

[donhall161]

George,

I don't have the '04 handbook, but I believe the HPF shown in the '02 is the 
same.

At my last QTH I was less than two miles from a 10KWday/1KW night AM station 
on 1720. The filter which I built and used successfully for keeping them out 
on 160 was the nine section one shown in October, 1983 QST, starting on p17 
by John Webb. It has a much sharper cutoff than the one in the '02 Handbook.
