Yes I remember that, Surprised it went that far. I and my father set up the
timebase to do 819line, but with restricted bandwidth on an old valve set,
but we had to use a band 1 audio tuner to get the sound. Those channels were
over 11 Mhz wide after all.
I always found it a little oddball to go from such a high line rate to 625
later on yet keep the old positive mod, as positive mode made the sync
pulses at the lowest output of the transmitter and hence prone to noise
more than the other way around.

No, I no longer have my rota aerial on the chimney, but I did plug in a
discone the other day and found duplicate channels up in the 800s, but don't
know where they came from, Hannington perhaps?

More likely local relays?

No they used positive mod for the 625 as well. They did this from what they
say to allow simple adoption back in the day. However, The few times I saw
it even in colour back then it was nowhere near as good as the UK negative
going system in my view.

Yes, that's what I said, so you ended up here with an unlocked negative
image, with peak white sync pulses

But how does what they do help them, I have to say though French TV did seem
to be pretty boring, even given that you could not understand the language.
Lots of serious looking men around chatting for hours, and Sacha Distel in

Yagis, especially wideband ones, tend to have alarming side lobes when
mounted for VP.

Very frequent problem here in Yorkshire. Customers used to complain. One
geezer called me a liar to my face when I told him it was interference
from abroad.

I believe France did/do use use VHF channels for their digital TV, at least one
of my TVs includes VHF channels if asked to do a full scan.

Full scan to include analogue?

Yes, if I'm lazy and don't change it from analogue+digital to digital-only

My LG TV can do an analogue scan, but by default it offers the same scan
as was used last time.

I have a box that takes in a SCART connection and outputs an analogue
signal on the channel chosen by DIP switches. I don't use it now, but
it is comforting to know that if I do, my TV can be set up to handle it.

The thing about Saccha Distel was that he was always 27.
Met him once. Lovely guy.
