I noticed the TV owner was using an antenna, instead of cable. I imagine
that the TV antenna (rabbit-ears dipole?) helped to transmit the signal in
a manner that could be received by the the satellite. If it had just been
plugged into cable, it might not have been strong enough. I bet more of
these sets get this problem occasionally, just it never becomes an issue.

The TV in the common area, in the building I live in, also throws of a
spurious signal on 121.500. It is an old "Citizen" brand TV,
connected to a "Rogers" cable coverter.
