Interesting thought. But water being a conductor would probably work as an antenna. I vaguely recall a military antenna based upon water spouts of the proper length shooting out of the ocean from top

I have 6 Sonos. I've not noticed any problems with 100w HF and 300w 2 meter. However, most of the time, most of them are unplugged as I'm listening to my ham radios / scanners. 7 3 Bob N2SCJ I'm thin

I see its listed as "Commercial Electric". That should be a tip off. Commercial lights are allowed to be noisier than one designed for home use. Sorry, can't quote the regulation, but it's been discu

Some of the dimmer packaging says "RF Quiet" or similar verbiage. If it does not say that, it's probably noisy. Bob <snip> Lutron I know someone who used to for for them, and he says all the designs

I've noticed that one of my computers emits RFI, but it's coming from the HDMI cable. I notice it mostly on 70cm/445.200. To a lesser extent, I've noticed it on the 6m SSB portion of band. It's very

Thanks for the comments. I ordered one of the newer 8K cables and will give that a shot. The description was bragging about how its "triple shielded", so maybe it's better. I recall the ones I'm usin

Any word on Vision Solar LLC? Quiet or noisy installs? Panels will be about 20 feet from my VHF antennas. HF perhaps 30 feet. Hopefully, the numbers don't work for them and they pass on the install.
