I found this advice on an eHam forum and installed the filter in my Rheem air handler. Eliminated RFI on 20 and 15, reduced on 10 but still bad on 12.

I used a 10 amp line filter from Corcom

Be careful with the 220 VAC!

The W1MG link to Mike Gruber's article has a broken link. Someone please correct this. I am planning to put in a new furnace, which has an ECM motor control.
