This works as long as the channels that the modulators are using are
free from interference and weak signals.  Co-channel interference from
distant transmitters that normally would be too weak to tune to can
cause 'wavy line' type interference if you set the modulator to the
same frequency.  This depends on where you are and the ability of the
Aeriel to reject off-beam signals.  In extreme cases you may need some
channel notch filters to remove the unwanted interference.

Of course the modulators are mono sound only.
