[Hallicrafters] HT-32 WHAT IF THING

[k0ewu at juno.com]

        This should be an April Fool thing?
As we know the 7360 is very sensitive to external magnetic fields the
normal shield 
is of a magnetic shield such as "conetic"
So if we wanted am from the -32 why not use the voice coil from an old
speaker placed around the tube.
Then using a small audio amp with a microphone feeding the "voice coil"
now known as a magnetic modulator, to alter the magnetic field at an
audio rate.
This should result in carrier injection detectable in a receiver as am?
