Hi,

I'm beginning to worry about our microwave oven. I've noticed that if
I'm using a bluetooth headset in the kitchen and I turn the microwave
on, the headset crackles very badly and then loses its connection with
the telephone. Is this normal? I doubt it.

The oven was a ridiculously overpriced built-in model, otherwise I
would be putting it straight in the skip and getting another one for
£19.99 from Argos.

Cheers!

Martin

other than encasing the microwave in lead, there is noway you are gonna keep
all the microwaves in. If the microwave is undamaged, then it will be ok to
use.

I'd do a quick testicle count every morning if I were you.
Any more than 2, & you might have a problem :-)

Nobody seems to know whether this had anything to do with Eva warming
pizzas in the microwave at the Berghof.

Was it that she looked over the Alps to Bolzano with its pizzas cooked
in a wood burning oven, but then decided that it wasn't quite sanitary
for her Fuehrer. Perhaps it was that she turned up the power level on
that first radar/microwave cooker as he stood in front of the waveguide.

She needn't have worried. In teutonic tradition, Dr, Oetker has
stepped into the breach in his white coat with his full range of
clinically sterile "Italian" food. http://www.oetker.com. One can
use a conventional oven, a microwave, a blowtorch or any other form of
calorific enhancement. The outcome will be the same.

The crackles are probably coming from the motor which drives the turntable.

Bluetooth works in exactly the same frequency band as microwave ovens
(around 2·45 GHz). Bluetooth uses extremely low power, so any minute
radiation from the oven (running at ca. 1kW?) will very likely
overload a nearby Bluetooth device.
I wouldn't worry.

Yep, I wondered if anyone else would say that. In fact I'm rather
disappointed that this wasn't one of the first comments but I guess people
just don't know how things work these days.

With 1kW of 2.4GHz RF about even -60dB of leakage is 1W which is roughly
100 times that of a Bluetooth device. Oh and the 1W of leakage is nothing
to worry about, your mobile phone will pump out 1W of RF and you hold that
right next to your brain...

But the 900MHz/1800MHz of a mobile phone doesn't have much interaction with
your brain and most of the 1W just passes through.
The 1W from a microwave is absorbed by the brain (to a depth of 2-3cm IIRC).

Try telling the newspapers that. B-)

2.4GHz is one of the resonant frequencies of the water molecule, which is
how a microwave oven works.

What ever, 1W of RF at 0.9/1.8/2.4GHz at a few feet isn't going to hurt
you.

Exactly. People expect all these 'wireless' gadgets, such as
Bluetooth, 802.11 LANs, all sorts of remote controls such as garage
door openers, house alarms, videosenders, 'walkie-talkies' and so on,
to happily coexist within a narrow uncoordinated frequency band...

The worst offenders are the broadband devices such as microwave ovens
and videosenders (often several MHz bandwidth).

Well..

I saw some vegetables that had been partially rotted when left for a few
days next to a real leaky microwave.. but that was a rather old one..

Yes they can leak..

But as stated bloo-tooth uses the 2.4 band as well as a lot of other
devices and there is going to be some radiation, but I rather doubt that
its going to cause you to suffer your molecules to alter

Aldi have a Draper microwave tester / screwdriver / continuity checker

Or I'm pretty sure that B&Q sell them for £1.99, but they are a no-name

Perfectly normal, there is always some small amount of leakage. Check
the case is undamaged and the door shuts cleanly.

RFI is not a safety issue.
Microwaves can be checked for leakage by checking the door closes
fully, and its not misaligned or bent, and that there are no rust
holes in the cooking cavity.

Or you can follow the 'other' advice, ditch a good machine and buy a
£20 crappy one, and waste another couple of quid on a gimmick that
claims to detect microwave leakage.

Its only 1970s and earlier nukes that may leak significantly without
being damaged.

Even if you think that part of it's a gimmick, it's still a circuit-

Thats optimistic, many dont work at all. Of those that do function,
they dont tell you what level the field is, and dont distinguish
between one freuency and another from somewhere else, making them of
little use.

And the fact that theyre an irrelvance to start with makes them even
less use. Leakage testers were appropriate technology back in the 70s,
but not today. Microwave oven design has left that issue behind
decades ago.

Why on earth would you get another? Microwave ovens use a very
simple and extraordinarily reliable method of stopping things leak
out of the door. It is called a choke seal and relies upon the
distance from the oven cavity to body edge. It is therefore very
robust - apart from physically bending the door to create a gap it
will work. All the stories you hear about dirt on the seal are daft
(unless its a pizza trapped in the door).

That said, all leak a little bit and that trivial leakage is usually
enough to disturb Bluetooth which is very low power to begin with.

A new oven would probably do exactly the same.
