RFI

Don't forget lighting dimmers. My dimmers, OEM, cause a buzzing in my sound system. I just don't use the sound system with the dimmable lights on. I don't know how far away from me the interference reaches.

Very interesting article however I find these three paragraphs of particular interest

Private signal sleuths, too, hunt down errant emissions. Jay Jacobsmeyer, president of wireless-engineering consultants Pericle Communications Co., investigates interference at 150 to 200 cell sites a year, mostly for wireless clients. His team last November faced a puzzling signal in San Diego that would pop up, disappear for weeks, then resume.

Using directional equipment, it identified a cordless phone on a yacht that occasionally visited, Mr. Jacobsmeyer says. The skipper agreed not to use the system in port.

Radio hobbyist Tom Thompson of Boulder, Colo., last year tracked a signal using a homemade contraption. After knocking on the suspect's door, he traced it to ballasts on marijuana grow-room lights. He says he built a filter that the grower agreed to use.

Man oh Man what some people will do

A key segment of that article....

article wrote:
The FCC had warned Brookfield in May, asking for progress reports, but it received none, the new letter said. It warned of fines and possible equipment seizure or jail time.

You will notice the FCC first warned, and ask for progress (Compliance) reports. and when Brookfield basically ignored them,< THEN it got a letter with stronger wording, Likewise the hair salon They took two warnings, but paid no fine,, GE fixed the problem no charge (as well they should).

Some of the earliest Winegard antenna amps were offenders.

Many devices in motor homes are potential offenders. INCLUDING but not limited to refrigerators, fuel and water pumps, Florescent and LED lights. and MSW inverters.

In nearly all cases the majority of those items are operating within certified limits and are 100% legal, but there is at least one model of Fridge for example which has that problem (The manufacturer WILL replace the control board if you have one). and the ballast for a 12 volt Florescent is really an MSW inverter.

But I stress.. ONLY SOME are offenders.. not by any means all. May be as low as 1 in 100 or less..

GREAT article.. Thanks Paul!

These issues are everywhere, but the FCC is so underfunded its not even funny.

Yup and this happened as well

Clicky

A lot of folks think that consumer electronics or electrical equipment are not thier responsiblity....

Popcorn ready.
