As someone else has said up-thread, the work wasn't at the transmitterThe multiplexers are nowhere near the transmitters, haven't ever been in

regions so each transmitter receives a *different* version of BBC One,
rather than most receiving a red slate during the regional news.

Sorry, I should have clarified that when I referred to "the
transmitter or its multiplexer" I wasn't implying that they were they
were located in the same place. I realise that all the muxers will be
in one central switching zone which will switch between (for example)
BBC One national and BBC One Yorkshire regional news (and likewise for
ITV national and ITV Yorkshire regional news or the Yorkshire-specific adverts), and send the combined PSB3 stream to Yorkshire's
transmitters, and likewise for all the other versions of PSB3, each
with its own regional programmes insert between the national programmes.
Am I right that, in essence, BBC One is now treated in a similar way
(similar topology) to ITV?
Is there a good BBC article which describes the before-and-after
technical setup and signal flow, and why BBC One didn't until recently
do it the way that ITV have done for ages?
However, not without risks (this is from 2007, so ITV have been doing it a long time)

Like I said, 'don't assume'. Most likely it'll be OK but sometimes,

The trees behind my father's home, in the direction of the Hannington transmitter seem to cause more problems in the Summer when they have

only a very slight variation. The HD channels are zilch. No signal
strenth at all.
Now when I first got the Humax the HD channels were fine. I don't see
how trees (which are not in leaf yet) can affect only the HD channels.
I must admit that we mainly use the Freesat Humax, with the Freeview
one being a reserve, so haven't tracked any change over the months.

At our last house we had trees in line (of Hannington) too, summer wasI was able to do that when the one tree was in the middle of a large lawn, and the lower branches had been trimmed to allow the sit-on mower to get close to the trunk.

tree canopy. That worked fine. It was LOS too, could make out the red
mast lights at night from the aerial.
