Default RFI from Switched power supply

wrote ...
I have the (incredible fast and reliable) Verizon fiber optic into the
house for my internet connection. So far so good. However at the
access point there is a battery backup unit for the fiber-Copper
converter. This battery unit is kept charged by a powersupply that
makes an ENOURMOUS amount of RFI that radiates onto the (15 feet) lead
into the unit and from there into the shack. (S6)

Does anybody have any suggestions on how to silence this? Or... a
suggestion for a cheap and 'quiet' powersupply? (It's output is a
regular 12v)

You could likely find a linear (old-fashioned 60Hz transformer)
"wall-wart" power supply at Radio Shack (and the appropriate
connector/adapter to fit your equipment).

I have FIOS in my neighborhood, but haven't signed up yet.
I'm going to give up waiting for the WiMax broadband wireless
network service and just go with FIOS.
