Hmm. I've just used my analyser and it is still showing a large^
carrier of something on C55. This is at 11pm Friday. It is about the
same amplitude as C55 always was ie. slightly less than the main 6^
but much larger than the mobile phone signals.
I've also done a retune and got nothing from C55 But I don't think
they've turned of the transmitter Com7 Sutton at this moment, just
not sending anything to it.

You're too late, all the COM 7 carriers dropped at bang on 11am

S.
It should have shut down without the transport stream being
present, as it's an SFN transmitter
Doesn't matter in this instance of course, but normally if a tx
loses its feed and it's in an SFN, the carrier should drop
otherwise it'll punch a hole in overlap areas

Hasn't COM7 already stopped broadcasting? Or is the carrier still
present even if it has no programme streams?
BBC Four HD and CBeebies HD still haven't appeared on PSB3. The channels
are listed in the table of channels, but there are no
video/audio/subtitle streams - as shown by TSReader. Looks as if some
last minute hitch may have prevented the normal seamless handover of a channel from one mux to another. I gather (from thread on DigitalSpy)
that the multiplexing servers for each transmitter's regional version
(*) of PSB3 are being changed at the same time, so it's a bigger change
than normal.
(*) To include regional ITV HD - and presumably regional BBC One HD in
the future.

With playable video and audio streams? On Belmont, the entries in the
list of channels on the mux were present right from when I first checked about 13:00 on 29 June, but they were index entries only, with no
matching video/audio streams. All I got was the "BBC Four HD will return
to Freeview soon" caption.

Firstly, the SI tables for all the transmitters had to cross refer to all
the other muxes carried by all the other transmitters.
This led to a huge unwieldy lump of data that gave some receivers indigestion.
And I'm not sure, as you say, the signals in the overlap zones were timed properly to give constructive rather than destructive reception.
I don't think anyone on the Tx side will miss it !

I can see the arguments for and against making COM7/8 into
single-frequency networks. But when it was decided to do this, why did
they choose such high carrier frequencies, *above* the 700 MHz threshold
that was being sold off?

What is the highest UHF channel that is now used for terrestrial TV in
the UK? I can't find a list of every transmitter and its frequencies,
to sort it by frequency.

From its conception t'was only ever going to be a temporary service.
It used spectrum that even in 2013 was headed for mobile operators.COM7 was originally at CH31,32,33 depending on transmitter and COM8 at CH34,35,37 similarly.

If the BBC mention the word "close", even if it is qualified by
"might" or "could", I think we can take it as read that it is the firm
plan to do so, even if this is an internal-only-not-for-publication
plan. Or am I just being cynical?

The message actually says that "BBC 4 HD will return soon" both in the caption and EPG (?). Presumably written by someone down South who is

this sub band (500 MHz band) had originally been cleared of broadcast services, and lay empty between DSO in each area, and COM 7 and 8 coming along in 2013/4.
I can't remember whether the original intention was to flog this off too ?

It seems a lost opportunity to rejig Com4, com5 and Com6 to become HD
and a SFN for the whole country as that could have freed up some space
for Com7 and Com8 to have moved down in frequency.

Just a quick check before I switch off C55 in the Triax TMB2000 and surprisingly, according to my spectrum analyser C55 carrier is still
there over a month after the mux closed. Of course I cannot be
certain it is still the Sutton Coldfield that is putting the signal
there but it is the same amplitude as before and there's nothing else continuous around it until you get down to C48.
I would have expected it to be shut down PDQ to save power and to
comply with license restrictions. Most odd to me.
