In the case of the "haunted" tape recorder, the RF
probably leaked into the microphone circuitry; the recording
electronics "detected" the audio and mixed it with what you were
saying and then recorded the combined signal onto the tape.


Hmmm.... in this case, the signals weren't combined: the extraneous
signal totally wiped out what I had taped for about twenty seconds.
And what I don't get is-- well, there are a couple of things that I
don't get now that I think about it.

First, is where such a signal would come from. There are no hams or
other sources close by. As many times as I have made tapes over the
years, this is the only time such a thing has happened.

First, a radio ham, with a transmitter powerful enough to mess
with your recorder would, in the vast majority of cases, be using
Single Side Band modulation and would sound like Donald Duck on
steroids.

So either somebody found your recorder, and was messing with your
head by recording something over top your recording, between the
time you made it and then listened to it. Or the erase head in
the recorder is flaky and that was what was on the tape beforehand.
