Topband: Topband BCB interference reduction

I've had very good success with the ICE BCB filter on
my RX antenna. The filter is mounted on the copper
plate of my single-point-ground system just outside
the shack and knocks an S9 +40 dB signal of the 50KW
WSB-750AM down to S7 at 0.750 and to zero at 1.500. My
suggestion is to make sure the filter is well
grounded, as I think it's especially important with
this type of filter.
