Default EMI Supression Required for Satellite Receiver

Harmonics of the switching power supply which is on all the time so the
remote can function. RF transparent case and a dipole consisting of the AC
cable for one leg and the cable and dish for the other. Probably more
efficient than anything a ham could come up with for a disguise antenna.
I'd be curious what the fundamental is, but some of those pulse width
modulated supplies are getting pretty high in frequency.

Hi OM,

Buy a power line, in-line RF filter. Sounds like you have a very
strong AM station nearby, and it is comming in through the power lead.
