Anyone using RS 12-150 AM/FM/WX radio?

Could someone explain to me why the SAT when
introduced to a radio causes the tone of the signal to change. The
treble seems to drop off a bit, but the bass and midrange become
stronger and louder resulting in a richer sounding signal. It's
almost as if the receiver is somehow more selective and concentrating
the signal into a smaller or more narrow area.

What you may be experiencing is the high Q of the antenna. This results in a
low bandwidth passed by the antenna. For example, if the Q is 200, then the
bandwidth at 600 kHz is only three kHz. Anything above 1.5 kHz in the audio
will be attenuated.
(note: I've assumed a value for Q. I don't know the real number for the
SAT.)
