Have another curiosity to figure out: A couple years ago I'd rebuilt my fathers 30 year old HyGain tribander & replaced the traps at the same time. It resonates well at the CW portion of the band. Ho

Be careful - there are probably drug dealers in your basement! All kidding aside, You have some RF in the shack. Youve mitigated a lot of it, but you are on the right path. You probably have some RF

My thoughts: 1) adding the good balun reduced the radiation from your feedline, thereby reducing the level of RF getting to the furnace system. 2) SOMETHING in the furnace system is resonant...to som

Some interesting thoughts. It's for sure RFI that's involved and I am ordering a fairly large quantity of ferrite clamps which I plan to attach to each coax termination & origin in my system. I'll ha

Why not figure out exactly which panel of sheet metal is thumping, and then either pull it tight by attaching a thin cable to it with a sheet metal screw and tying it off to a wall, or pushing agains

Sounds as though you have two challenges: 1. How is the RFI getting into the system (and how to stop it)? 2. What, precisely, is causing the "thumping" (the collateral consequence of the RFI)? points

I missed the low roof-mounted beam detail - that increases the likelihood of indoors resonances! Most low-level RF-exposure fear-mongering, other than at SHF/Microwave frequencies, is likely junk sci

I heartily agree. At that age, we must treat such people with kindness and concern. To me, this is so very unusual that it warrants extensive search and examination. Do you have any one who could hel

"HiFi" speakers have been known to thump in rhythm with the sending of CW when the amp is OFF! Not sure what is actually thumping, but the idea of finding a panel that's doing it might be of value. *

I remember very well when the FCC first adopted these rules. I did a lot of homework at the time and, to my mind at least, it was junk science. I don't blame the FCC (much) for adopting a standard, a
