Which genius planned Bath/Backwell relays to use exactly the same (analogue)
channels then? From a lot of the target area of Backwell, it is almost
directly in line with Bath and you get dreadful line pairing sometimes.
When Backwell suffers one of its many breakdowns you can often get a quite
watchable picture off Bath (locked, B&W anyway).

Freeview at all.


Yes, there are saver restrictions on the resources of the problems
involved in another.


Of course they are. There are the fault of Sandy Heath.


Kaine fights back, knocking Ben unconscious. When Ben awakes, he's
pierced by a variety of shifter. It is believed to be caused by a
pentacle.

Get an education you ignorant imbecile. If you live directly under a
transmitter then you are in no better a situation for receiving the signal
that if you were living 50 miles away since the beam from the aerial will
pass a hundred feet above your roof and your aerial will receive almost ****
all of a signal from it. Learn the basics of aerial characteristics before
you open your ignorant mouth again. FOOL!


They certainly can't be used as magical defences.


You are showing once again that you are an ignorant piece of ****.


Not everyone was running around killing people.

He would have done if he was a powerful page. He threw a tantrum. He

The STB is top of the range.

IGNORANT IMBECILE!

C67 from Dandy Heat is on 10 times less power than every other multiplex.

DO SOME RESEARCH YOU MORON BEFORE MAKING A FOOL OF YOURSELF!


There is little point hiding its artificiality. It is naturally a
finely divided powder, whereas coal tends to clump as larger
particles.

What does my TV have to do with this matter when it's my STB that picks up
digital and its a top of the range Sony. MORON!


Visitors contained the clip used in many ways, transcending the actual
or alleged limitations of its former days, but its importance is
rising fast.

AIUI people living south west of the Redruth transmitter have similar problems
with Wenvoe. Using 39, 42, 45, 49 might have been a better option for Redruth,
but I suppose something in Eire or France prevents that.

Hmm, after the kind of reaction I've read in this thread, I'm hoping
my comments will go down a bit better. I'm also having trouble with
the MUX2 channels and I live in Bicester. The signal quality seems to
have degraded over the past 2 months. Previously, I could get the MUX2
channels at a decent signal quality using my freeview box and a crappy
usb tv tuner for my pc. I was quite pleased. However, I now struggle
to get a picture with the freeview box and the usb tuner and my new
£60 digital tuner for my pc can't pick up anything on MUX2. Now, this
change in fortunes seems to have been related to the high winds that
occurred about a month ago. I'd honestly say it could be the aerial,
but ours is in the loft and there is no draft in there (and the aerial
is about 25 piece so it take more than a slight breeze to shift it).
At some point I'm going to take a trek upstairs and try to reposition
it, but I find it strange that nothing much else seems to have changed
but I'm having these problems.

I know the mux2 signal from Oxford is fairly weak, but could it
possibly be causing this bother? I'm only 20-odd miles away!

Unless you live in a detached house, have you considered what your
neighbours might have been up to in their loft? Stored something large
and metallic up there, perhaps? Or a new water tank? (I know they're
plastic these days but the water could be a problem.)

There is an 18 element Belling aerial in my loft, it was there when I
moved in. I replaced the domestic downlead with CATV grade RG6 many
years ago and have never had any problems. As it points towards the
front of the house towards Crystal Palace about 10 miles away, I
wouldn't expect any - and the one time I measured the levels I was
getting around +17dBmV on analogues!

However, Im still conscious that it is only a couple of feet or so away
from my neighbour's loft, and they could unwittingly do something to
cause me problems, but I'm trusting to the very awkward access to that
part of the loft area to act as a deterrent!

The Belling aerial, by the way, is one of the original design with the
light blue connection box that first appeared in 1964 when BBC2 first
started!

That's interesting. I can ask them. I'll double check the loft
connections as well, in case something has gone wrong.
