Just noticed that:

Speech scramblers (frequency inverter type)
on my GBP15 a pair Tesco PMR446 is legal.

Exactly the same as my Wouxun hanheld is not.

Both the same, both decodeable by the same
freely available PC SOUNDCARD software for nowt.

What an OFCOM contradiction.

No contradiction at all. Amateur Radio is deemed to be broadcast for general
reception, otherwise it would not be legal for anyone to listen to without
authorization.

This is not the case for PMR446, despite it being licence exempt (from S8
for the WTA2006) it is not exempt from the requirement to have authorization
before you are allowed to listen. So privacy is expected (but not achieved),
and scrambling is lust an adjunct to that.

Nonsense.

Licence exempt means just that - anyone can transmit, and anyone can
recieve, on those frequencies.

I've just asked OFCOM for claification.

Might take a few weeks to get the answer, but OFCOM are
very good at resolving this stuff.

Lets see what they say.

No it does not.. Read the SI that invokes the licence exemption. It only
exempts that service from S.8, NOT S.48.

So since there is no blanket authorization, (as with AR), it is illegal to
"obtain information as to the contents, sender or addressee of a message"
unless the sender authorizes it.

Anyone can transmit, but only the intended recipient is authorized to
receive.

This is the case with all licence exempt services, with the possible
exception of CB.

By virtue of the way PMR446/LPD433 operates, what your suggesting is
actually completely impossible.

Don't worry, there's probably a department at Ofcom specifically to
answer questions from "Radio Amateurs who can't be bothered reading
between the lines".

If you can you a transceiver on a frequency or set of frequencies
without a licence, then ANYONE can listen to those frequencies.
Especially when there is no requirement to use CTCSS or DCS on them,
like PMR446.

It's a good thing though - helps move folk using PMR446 for business
purposes onto UKGL and other systems. Which is better for all users.

I'm told it started with the late G8N**'s or early G80***'s

As a former "Civil Servant" it was impresed on me it was easier to say "NO" than

When some body appealed against the decision it went to a "higher level" and "he"

Well actually No. In order to breach S. 48 you have to have intent to obtain
the content of a message, so just checking that the frequency is clear, or
having a message appear without warning is not illegal. That is why speech
privacy is allowed on PMR446.

However, intentionally listening to a message is illegal.

Indeed, analogue portable phones operate under exactly the same set of
regulations, and I am sure that no one would suggest that listening to those
was legal.

You can't use an analogue cordless phone to listen to another one - but
you can use a PMR446 to listen to any others.

The exemption only applies to the correct equipment.

I never seem to have these problems, maybe it's just you ;-)

And in the case of RA/OFCOM, you'll be surprised at how
accomodating they are.

Oh no, not at all. I had one that you could use as a scanner - you keyed

Luckily it's resorted back in its latest re-incarnation. I don't see
how OfCom can issue any variations in the future without a statutory

Mate of mine back in the late eighties got a job with motorola.They
all had engineering brick phones and hand portables that could do that
- also could do three way + conference calls. His gap year involved
being driven around the UK in the back of a blacked out "A-Team" van
checking signal strengths and call quality. Absolute peach of a job
for a student. Almost as good as chasing seals around the north sea
supergluing transponders on to their heads or wacking UHF TV panels
into shape with hammers 1000 feet up on the end of a rope - oh happy
days ;-)

Oh! but you can. Listen to analogue handset out of range of your base and
you will hear any other conversations on the same frequency, and in a lot of
cases be able to make a call.

Does this mean it is a bit more specific? The OFCOM doc. which I have
(replacing BR68) was so vague, there was no way for example, that proved
that one is able to tx/rx television of any sort.
I did query this at the time and the response was equally vague, my points
were noted but it was suggested that I did not hold my breath awaiting any
change!

But more importantly, it doesn't say you can't.

My local police repeater was carrier-operated right up until (and
