The spectrum analyzer runs all the time, usually showing the range from 150kHz to 1800kHz, and today I noticed a pulsing wide-band peak centered on about 400kHz and spilling into the low AM band, with a reading of 30dBm.
I tuned the Zenith to 400kHz and there was a blasting buzz that sounded like the radio was next to a microwave oven or x-ray machine.
Yikes, I thought, must be HAARP blasting our internal organs with radiation just like Alex Jones foretold. As the day went on the analyzer reading increased to 50dBm!
So I recorded the sound for another “strange reception report” for the next Low Power Hour.
But that hidden voice that tells me secrets of existence suggested I flip off the wall switch feeding 3-LED light bulbs in the ceiling fixture. The buzz totally stopped.
How come I hadn’t noticed the buzz before? Those bulbs were put in over a month ago to replace the compact fluorescents, which produced a terrible quality of light. Originally I’d only installed two of the LED bulbs, and they seemed fine, but the other day I added a third bulb.
Either the three bulbs together are generating the noise, or the third bulb has a problem.
Let’s devote a day to figuring that out.
Bulbs that radiate the public? Is that what they’re giving us?
Are the bulbs radiating? Or, are the bulbs injecting a carrier-current buzz that travels on the AC line? Can’t have it.
Please send reports of your bulb experience.
