I installed the "Tripp Lite Isobar" and it did nothing to suppress the RFI. It's purpose is a "surge protector"...Don't buy one.
I finally received the proper RFI/EMI from Speedqueen (for free) and that fixed the RFI problem in ALL my radios, including my AM broadcast radio. Now I can hear WLW in the clear!

Hi Jan (N8CBX):
Glad to hear you solved the RFI problem and that Speed Queen supplied the RFI/EMI filter. What does it look like?
Every RFI/EMI situation is a little different. I've had great luck with the Isobars at two QTHs, when attaching them to Whirlpool front-loaders with touch controls. In those cases the problem was with RFI/EMI getting INTO the machines on 40 and 80M from the AC line, when running QRO.
Your problem was with RFI/EMI getting OUT of the machines onto the AC line, apparently, and INTO radios, which are MUCH more sensitive to noise thsan washer controls are. So perhaps the tiny ISObar you picked simply could not provide the level of suppression required.
And the bigger ISObars DO have quite a bit of EMI/RFI protection, including wound ferrites and balanced toroidal chokes. Here are some details:

Of course you picked the smallest, cheapest direct plug in model with the least room for this circuitry and a known safety issue you were warned about. One reason why I use the 6 and 8-outlet corded units for my applications. I've never had a problem with them - in use at my stations and on sensitive appliances, for decades.
In cases where I needed MORE suppression and when manual winding of ferrite chokes/toroids on the supply/signal lines was not enough (generally for sound systems/receivers), I've used AC line isolation transformers, which do better but are more expensive - unless you pick them up at a swap meet as I do.
Regardless, glad you're up and running. The Speed Queen machines tend to run forever. I gave away a top-loading washer/dryer pair that was 30 years old in favor of the more efficient front loading Whilrpools. The Speed Queen washer still worked fine and washed well, but it used a huge amount of water for each wash cycle. The Whirlpools have their own quirks and are not as solidly built, but they're very efficient (and seem to be RFI/EMI quiet but RFI/EMI sensitive), which is important in CA and at another QTH that uses a septic system.
Hope to hear you on the air soon!
