Thought this was a common problem, but couldn't find any similar posts.

Each time my furnace or central air kicks on, I get a strong (S9) signal on all HF bands (mostly AM / FM modes); that wipes out most stations from being heard. I tried placing a couple ferrite cores on the AC supply source, but didn't make a difference. Possible grounding issue, antenna height or poor coax connections?

I've used the same equipment at different locations over the years and never had an issue like this. The furnace is only 2 years old, so maybe something in the fan control itself. Any ideas?

Thanks!
