BBC and ITV muxes disappeared

This morning while watching "Breakfast" there were a number drop-outs.
Tonight nothing on BBC or ITV muxes at all, yet "Dave" is still there.
Looking at the signal strength, it's flicking between 70% and 0%. I'm
on Crystal Palace and luckily I can also see Reigate. Changing aerials
to the Reigate one and retuning the BBC mux, the signal strength is 65%
but the quality is only around 55% though with no drop-outs. I take it
that there's a bit of a lift on at the moment, though I'm not sure
what's taking out CP - Belmont could well be the culprit.

But how far are you from the Crystal Palace transmission tower?

Yes, that would seem the most likely case:-

Here in North Hampshire Belmont is a regular visitor, but only since the mast
was modified for DSO. Never used to get a peep from it during lifts when it
was taller !

How can you be certain that the ability to receive Belmont is due
to the shrinking of the tower and not due to the increase in power
and the change in FFT from 2k to 8k?

Since the transmitting antenna for the digital multiplexes were already
lower down the mast when analog was at the top, has the reduction in
mast height actually resulted in any real change in the height of
the tranmitting antennas for digital?

Check your aerial lead is still in the wall, that a big gull / gust has not
twisted you aerial round etc.

It gets in under the radar.

He never said it was due to the shorter mast. He just said he started to
receive it when the mast was shortened.

That's a good question and one that I'm sure someone here will know the
answer to. All I can tell you is that Belmont comes blasting across
Yorkshire, confusing the populace as they go about their lawful business
of doing endless factory resets in attempts to banish Peter Levy from
their screens.
After Yorkshire has a UDI the first priority will be to erect a wire
mesh screen approx 350m high along the south-east border. As leader of
the provisional government in waiting I have already begun negotiations
with a local fencing company. This was at the suggestion of the Bash
Anything That Doesn't Work Reight With a Big ****ing Hammer Party, which
has a majority in the county.
However an alternative solution has been suggested by the minority Nay
Lad Let's Fettle it Some Other Road That's Cheaper And More Cunning
Party. Their idea is to broadcast copies of the six muxes from Emley
Moor on the Belmont channels. This should prevent anyone with an Emley
Moor aerial from inadvertently tuning-in a Belmont signal, and would
also have the advantage of greatly reducing the Belmont coverage area,
even in places where they like Peter Levy, such as geriatric homes in Brigg.
The option of launching a satellite from the top of Holme Moss to
broadcast jamming on channels 22, 25, 28, 30, 53, and 60 has been
abandoned, following the police raid on the Chinese Firework shop in Maltby.

Check that your downlead is still there. Copper fetches a good price at
the moment.

That's right. In fact I was receiving Belmont analogue, a couple of
months before DSO. I assume that was because the analogue transmissions
were being stuffed through the new S1 array, that is now used for the
post DSO transmissions. So the DTT reception conditions now, are the
same as those few months when analogue was using the same aerial.

The beam tilt probably differs from the old 'analogue' stack.

Before that, I've never received in almost 40 years of searching the
ether round here during lifts any sign of Belmont. Emley Moor, and
Winter Hill have always been regular visitors however.

Back in the 1970s, the Rediffusion mast on the downs near Eastbourne used a
wire mesh screen on the back of the COP aerials to keep out the French
channels quite successfully.
