[CQ-Contest] RFI FROM A FRIDGE

[Dick Frey]

After locating a gas furnace as the source of intermittent RFI at a
local ham's place I was wary of them. Last winter I had to install a
new furnace. I chose a Lennox 97.5% efficient forced air job with a
variable speed blower. I told the heating contractor that it must not
interfere with my radio.

He checked with Lennox and discovered an add-on RFI filter ($90) was
available. It turned out to be a two section 10A line filter I could
have bought from DigiKey (108-10DRCG5) for $15, but I didn't have to
install it nor raise warranty issues. It works.

 

An ounce of prevention..
