(2) The degree of AM BCB intermod, especially below 4 MHz, is
dramatically increased, almost to the point where nothing legitimately
below 4 MHz can get through. All preamps off, still get the gunk
where it wasn't before. Booo.

You might want to look it over for a wire pulled loose, a cracked circuit
board trace or a poor solder connection. It's possible you did some
inadvertent damage as you disassembled it. Happens to me from time to time.
Even if I didn't spot anything, I would probably shotgun a bunch of solder
joints with an iron.

Thanks for this Frank - I will look and maybe solder too, although all
I really did was take the top off - I doubt if I will find anything
(not having any significant experience with looking at a circuit
board, much less with a soldering iron) - but I am still puzzled as to
how the signals are getting into the equipment in the first place -
with the preamps all off, the MFJ's built-in MW attenuation and the
PAR filter there, the signal strength just isn't there - on the
antenna at least.

After another experiment, FWIW, I get this on the radio without the
MFJ-1026 installed, too. The RFI is just *everywhere* around here.

Thanks,
Bruce
