At XZ1N, we used a very tight bandpass filter- 1.8-2.0 MHz - 60 DB down at
1.6 Mhz. This filter immediately killed off all the crud we were hearing
from a 1735 Khz station in HS, and eliminated the overload thumps we were
getting from the KW on 3.5 at the other end of the hotel, and allowed us to
use the preamp on the beverages.
This filter is RX only, and is made by Jim Owens NW0O - at Mil Rad
303-673-9019.
