Anglophile tellies

We have a number of tvs fed from the one aerial via an amplified
splitter. I'm noticing the same odd behaviour from two of them: a Slingbox
(OK, not really a telly) and a small-screen Technika.

When autoscanned, both of them insist on putting BBC1 and ITV1 (England -
probably from Mendip) in the prime slots (1 and 3) and the Slingbox
totally ignores the Welsh (Wenvoe) alternatives. This despite the fact
that the Mendip signals are too weak to be usable while the Wenvoe ones
are a good strength and on lower UHF channel numbers (so they are scanned
first).

They also show BBC1 and ITV1 rather than BBC1 Wales and ITV1 Wales in
their channel listings. The Slingbox proceeds to announce that there's no
signal while the Technika just breaks up all the time. (While I'm
mentioning BBC1 and ITV1, the situation is no better with BBC2, Channel
4, etc. Only the COM multiplexes come in properly.)

Fortunately, scanning with a 12 dB attenuator in place sorts out both of
them but I'm a tad suspicious that this is some sort of bodge in the
firmware to reduce complaints from English users who were finding
themselves tuned to S4C, etc.

It could be that the receivers are finding a weak local Wenvoe relay
down at the bottom of the UHF band, between UHF Chs 21 and 30, and
subsequently ignoring what they consider to be a duplicates from Wenvoe
itself at 40-50. They reach Mendip at 50-60, consider that to be the
primary Tx, because it's stronger than the Wenvoe relay found initially,
and stick its channels on the primary LCNs ?

What (if anything) gets stored at 800+ ?

Mind you, people the other side the Bristol Channel would pay good money
for any receiver that magically ignores Wenvoe ! :-)

It could be the Kilvey Hill muxes which are Group A but very weak because
of a hill in the way and the aerial polarisation being wrong. But surely
it'd be catastrophic to ignore a decent signal because an unusable
version was seen first?

The Technika puts the Wenvoe versions in the 800s. The Slingbox doesn't
and it doesn't have manual tuning either.

I'm just speculating that it was the moaning from those across the
Bristol Channel and in Lancashire that's being addressed and that the
balance needed to be evened up.

Anyway, the whole issue of tuning of digital terrestrial receivers is a
right mess. It's not like these problems couldn't have been foreseen and
addressed in the specifications. E.g. after scanning, list the regions
and let the user choose which they want as the primary one.

And people on the Welsh side would pay good money for any receiver
that magically ignored it too, I mean, "Clirlun" and have does anyone
actually watch S4C ??? The choice to opt out would be really, really,
really nice.

There's a good argument for putting West on Wenvoe and Wales on Mendip.
