Which companies have run the Channel 3 services in the Divis transmitter area
Because when I switched my own LED downlighters off the noise went down considerably!
The QRN seems to be type-specific to MR15 LEDs. I have now changed them out for GU10 230V ones, which gave no noise with a portable radio (on an empty VHF frequency) held close to the base. The noise seems to have been radiated from the lamps themeselvs and not through the mains wiring. The (separate) SMPSU's could have been part of, or the, problem as they were designed for halogen filament loads (one burnt out). In any case the safe and cost effective solution was to bin the lot and fit GU10s.
Although the noise problem in my flat has largely been solved for the VHF band there is still noise especially in the evenings, so I suspect from a neighbour. My own MR15s blocked next door's VHF too!
Anyway I tested all my other LED lamps (ES and BC) and none of them are noisy. I only tested on the VHF FM band and there is much noise on HF, hence my interest in the spectrum analyser dongle.
I hadn't noticed that about filamentary type LED bulbs, I guess they drop the voltage by lots of LEDs being in series.
