The latter maybe, but surely not the former ?


BBC News HD is useful for Click, when it isn't cancelled or truncated to
make way for (supposedly) "breaking news".

Channels 61 to 69 a the top end have already been given over to 4G,
now they're coming back for a second bite for 5G from 49 to 60, TV has
to be squeezed in 21 to 48.


Does that mean that channels 55 & 56 are only temporary, and when we
have to tune lower down maybe a group 'A' aerial will work again?


55 and 56 will represent a 'guard band' in the new 700 MHz mobile band.
That guard band will be retained for broadcasting until 2022, at which
point COM 7 and 8 will close.

Everything that is currently between 49 and 60, is being moved 'down
band, between 21 and 48. COM 7 and 8 have been up until now in the 31 to
37 range, this area is the refuge for the other 6 muxes (and local
muxes) therefore COM 7 and 8 in all areas will be moving to 55/56 before
the end of 2020

I too have lost channels owing to the abandonment of the sensible
grouped channel system. I don't know why they couldn't have put the new
phone allocation at the top of the UHF band instead of the middle, but
maybe the high channels are useful for fill-in transmitters.

My understanding is that they did exactly this by reallocating the top
part of the TV band for telephony.Â* My understanding is that channels
55 and 56 are in the centre of the new 5G band where there is a gap to
keep the transmitted and received mobile signals apart; and that slice
is temporarily used for broadcasting.

Mark can keep us right if necessary.


If there are/will be telephone signals below, as well as above 55/56,
what is the point in all those at800 filters they distributed a few
years ago and that most people will have lost by now?


Yep !

Somewhere on the Ofcom website is a study examining the performance
of receivers using 55 and 56, in the presence of strong '5G' signals
either side.

In short if they cause problems, then tough. COM 7 and 8 are sacrificial
muxes, you'll just be given a 700 MHz low pass filter instead to chop
everything above UHF 49

They are temporary until after the next but one election, at which point
terrestrial broadcasting will be reduced to one mux carrying the five
basic channels on a national SFN.
Objectors will be hushed and told that since 'everyone' has fast
internet and/or satellite they should use that. Their comments will not
be reported by the mainstream media. Since from 2020 onwards all
internet messages will be scrutinised for hate speech by a robot sensor
the only available medium will be the walls of public lavatories, the
graffitists wearing a balaclava and Corbyn mask. Dissent about the
effective end of terrestrial broadcasting will be classed as hate speech
(Public Order Act 2022) and anyone speaking out of place will be locked up.

Bill


Very funny, but public lavatories were the first facilities to have been
removed.

Truncating or cancelling 'Click' would be the kindest thing to do to it...

height that you get no signal at all.

Once the the aerial is high enough to have line-of-sight further height
will not increase the signal strength received. It could even reduce it...

The latter maybe, but surely not the former ?, especially now that
that female who threw a hissy fit and left, and has grudgingly
come back on a much higher unjustified salary, seems to be a
regular face.


"Golden girl six-figure auto-cue Carrie Gracie was reading the news
yesterday:

‘Unjustifiably high salaries paid by some academies’.

Oh dear me. It gets better:

‘MPs on the Public Accounts Committee (PAC) highlighted how 102 academy
trusts paid some senior staff over £150,000 a year. And in two-thirds of
cases where the government had challenged this, it had not been
satisfied with the response’

Ouch.

‘PAC said: “Unjustifiably high salaries use public money that could be
better spent….”

Luckily our Carrie, apparently, has no shame."

There's more to it than that. As Francis Xavier said, "Give me a child
until he is seven and I will give you the man." The BBC is intent on
brainwashing our children into accepting multiculturalism and their
other leftist/liberal values as the norm.

Can I at this point draw contributors' attention to my recent post on
the subject of these filters?

Yes well at the time they had become superfluous, but then the telephone
boxes went as well.
