Re: Indoor apartment antenna rfi

I glean from what has been said is that an LED light supplied by a 5v power cord supplied by a 12v battery should not cause much RFI.? If I am incorrect, please disabuse me of my error. 72/73 DR TIMOTHY-ALLEN ALBERTSON

Guys LEDs generally do not produce wide band hash unless they are smart dimmable?or are some kind of array.? Many of the sources suggested will produce noise on a particular frequency or band but wide band noise on all bands Is something else.? Old cfl?fluorescent bulbs were notorious for noise.? Aquarium heater were also bad, but you could tell easily as they had a glowing neon lamp in the heater.? Switching supplies (computers have these) will generate noise when you are close to them. I have to ask is the noise still present if you remove the antenna?? If so, you might have nose entering the radio from nearby equipment.?? Al wb9uvj
