After 21 years as a T-E. I'd have thought you had had enough of radio interference and not needed to listen to it at all, even though it is free ! :glee::glee::glee:Quote:

That's entirely logical, but it's perfectly possible to knock out VHF-FM. A few years back I was designing a class D (PWM) audio power amplifier which ran on similar power rails to an 80V stepper driver and with a not dissimilar switching frequency (about 300KHz IIRC). In spite of the pretty massive LC output filter, with a lead running to the loudspeaker consisting of a couple of pieces of 1.5mm2 twisted together it completely obliterated VHF reception in the workshop.Quote:

Voicecoil,
If you're going to be THAT determined even the power of Auntie will have to give in. :sorrow:
It was entirely unintentional, and indeed a problem that took quite a bit of shielding (including a screened speaker lead!) to solve. So were you at Wood Norton then? A couple of colleagues of mine went through courses there, just the best training on the planet at the time: shutting it down/farming it off was probably the worst thing the BBC has done.
