I don't have that problem, however I'd be inclined to try a LC series
trap
in series with the offending antenna, as the cheapest experiment (pick L

to resonate at the broadcaster's frequency, to remove it
perferentially), or even
just a resistor, to see if overload is really the problem. Or a MFJ-956
passive
antenna tuner, off the shelf.

Or swap the antennas, and null the broadcaster with the ALA-1530, which
is then the
noise antenna, by orienting it. Or you can null the station with the
wire antenna,
though it's likely to be more inconvenient to reorient. Every antenna
has null.

A slight disadvantage of tuned traps is that they change the attenuation
across
the bandwidth of a station, so you can never quite eliminate the entire
station
across the audio spectrum because the second antenna still has the
original
shape.

On the internet, nobody knows you're a jerk.

I compared the board to a schematic I found online which shows the bc
trap and jumper components. Apparently the model I have is an earlier
version lacking these revisions. Regarding your suggestions, swapping
antennas proved ineffective, as the loop generally did not hear the
noise, and when it did the level was far lower than on the wire, making
canceling difficult. Using a twelve foot dipole I had no overload issues,
but found it to be too short in some instances. I'm still looking for
instructions on building a trap or bcb filter, but I'll keep
experimenting with antennas in the meantime.

Brian,

I have plans on how to build a BCB filter that I could send to you as a
PDF once I return to work and scan the document. Fortunately, I don't get
back to work until Jan. 2.

Cheers!

Thanks John! I sincerely appreciate and readily accept your offer. You can
drop the pdf at briancummins at the gmail. Thanks again.
