GSM phones are the number one culprits for breaking into audio equipment of
all kinds. You can ban them from the studio itself, but how do you keep all
of them at a safe distance all of the time ?

Then there are VHF and UHF two way radios that travel around in commercial
and private vehicles - even the briefest injection of the signal from one
means having to redo something.

EMC screening is just as important as ever for a serious recording facility.
Continuous welded 2mm mild steel typically does the job.

That is magnetic screening - totally different thing to EMC screening.

The M in EMC IS "magnetic".

Er - no. The EM in EMC is electromagnetic. That is totally different to
magnetic.

The EMC regs require where relevant *magnetic* compatability.

Where relevant. If you are mounting something next to a leaky mains
transformer, then you need to worry about magnetic induction. Do you
know the most troublesome magnetic induction noise in a studio? It is
the ground loop. To stop that you have no choice but to break the loop -
you can screen 'til you are blue in the face and you won't stop the noise.

Look pet, I record on location for a living. Not some amateur know it all
like you. And any equipment which picks up phones from more than about a
couple of feet is just plain badly designed - assuming it's been designed
since mobile phones, that is.

As for two way vehicle radios, yes we've all heard that coming through.
It always means there is a problem like a bad joint somewhere that is
rectifying.

More likely a semi conductor junction that hasn't been by passed at
those frequencies...

You don't screen it, you fix it. You can regard the local
minicab company as a diagnostic aid.

Now less of a problem in practice with the demise of AM modulation
systems..


** GSM phones ARE AM !!!!!!!!!!!!!!!

The carrier is gated on and off hundreds of times a second.

That is why they make audio gear buzz - you dumb ass.

The old analogue phones were simple FM and had no such issues.

GSM with its QAM mode is the most "apparent" interferer and is the most

Yes "if" your equipment will "respond" to those signals

"Dave Plowman (News) Complete **** "

It's a poorly designed piece of equipment that picks up a GSM phone unless
it is right on top of it. I'd say within 3 ft or so. Plenty is very much
better than this.



** So ****ing what ????????????????????

The real world is FULL of poorly designed audio gear.

****ing musos own bucket loads of it and DRAG it all into recording studios
when they go there.

So in your world, mild steel is not used for magnetic screening. How are
things on planet Phil these days?
