Modern electronics and radio interference

Which goes to show you don't have a clue about the specification of magnetics in a SMPS.

You won't find many pure sine waves in a SMPS and that goes to show your ignorance on the subject.

Best stick to chemistry.

Ah, the admission of a lost argument. I wondered how long it would take.

Because we have so many laws that trivial ones that don't excite the media are ignored.

It has NOTHING to do with the specification of the magnetic in a SMPS unless you are stating that very poorly.

Have fun actually citing that specific law.

If you were designing electronic equipment in the UK you would know:

But since you obviously know very little on the subject, your ignorance is understandable.

Which goes to show you know nothing of performance of materials used in magnetics.

Best stick to chemistry.

Finally an admission you don't have a clue.

Another admission you don't have a clue.

My son is studying for a degree in Cybersecurity and Forensics and is currently on a placement with the police. He is just looking into amateur radio as part of this and was telling me the other day that it is common to use electronic means rather than physical QSL cards now.

That doesnt make chinese switch mode plug packs illegal.

Try again.

Is this "the" MFJ? They used to make great kits back in the 70s/80s/90s.

I have to say that, however annoying the Ozzies are, they have top-notch hams over there. Peter Parker VK3YE is fire.

Of course. Why would they not be?

Because they were an EU thing ;-)

No, actually they weren't.

They are all covered by British Standards. And always have been.

That these are similar to and in many cases superior to EU standards is neither here nor there.

You don't need to be part of the EU to work with the rest of the world to develop common standards of RF emission. Or electrical safety.

The CE stamping we were required to show will be replaced in due course, with a UKCA one. But nothing has changed.

Looks like you're replying to yourself.

When I had a proper job, back in the late '70's there was also the International Electrotechnical Commission. As a Swedish company, we were required to comply with their rules.

EUroMorons can never see the difference between individual voluntary compliance with stuff that makes sense on an international basis, and compulsory compliance with stuff that does not.

Yes maybe, but the challenge of hearing the direct photons from a distant station is still a thrill. Unfortunately its one that is much harder with the current levels of interference.

A couple of years ago, connecting devices in the home via a network over the mains used to create huge amounts of noise, but the most recent interfaces seem to be much better in this respect. I'm not sure what has been done, but it has obviously been prompted by complaints, I'd imagine, after all the mains was never designed for use as a transmission line. Brian
