The GE Superadio III is very good. (About $50. Radio Shack used to have an
equivalent. Not sure if they still do.) It is actually *wider* than 10Khz,
so at
night, you're going to hear the 10Khz heterodynes from the
moderate-to-strong
1'st adjacents. (An outboard 10khz notch filter will help.) Lord help you if
the desired station is running (or is within 20Khz of) an IBUZ signal,
though.

The sensitivity in WIDE mode is reduced, so only signals that are >2mv
(estimated) are receivable that way. In Narrow mode, the sensitivity is
incredible.
I haven't measured mine against a Field Intensity Meter, but it's gotta go
down into the 0.0x mv/m range. (Note to self: Next time I have the FIM, do
this.)


-----------------

I measured the sensitivity of an early model Superadio using an H-P 606A
signal generator, and it was something like 7 uV.  Not mv/m though  I
haven't tried that with a Model 3.
