LG LED TV 'slipping' onto wrong transmitter

Perhaps there is an option to disable automatic tuning, which should prevent this.

It is not practical on my LG, unlike my ancient Topfield which I can set to Waltham transmissions only, or more and then remove any unwanted channels (by transmitter if desired) and then store the preferences for next time I might need to do a retune.

Does the tuning logic in a TV always ensure that all the 3 or 6 multiplexes that it is tuned to are from the *same* transmitter, in cases where you can receive muxes from more than one transmitter?

The TV at my parents' holiday cottage in Wensleydale has an aerial pointing towards Bilsdale. But one day I noticed that ITV was showing the Leeds-based Calendar local news instead of the Newcastle-based equivalent. I checked the TV's tuning menu and all the UHF frequencies were for Bilsdale except PSB2 which was an unknown frequency which I presume was PSB2 for a relay of Emley Moor. I wish I'd noted what the frequency was...

To this day I can't think which relay of EM would have a strong enough signal to be picked up near Leyburn with an aerial that was pointing due east at Bilsdale, even during abnormal signal propagation.

I've had Belmont on that aerial very occasionally, using my own DVB-T2/USB tuner, which is going some for a transmitter which is about

Mind you, where we are now (Bridlington), Belmont's signal is very occasionally denatured by Crystal Palace's which is on almost the same bearing but 185 miles away! Belmont and CP share all the same frequencies :-( As an aside, I wonder if the interference would be any better/worse if it was the same mux from both transmitters, than if (as is the case in reality) different muxes.

No, but the pattern of frequencies employed, does.

That is, one frequency is one transmitter and one mux.

The frequencies are deliberately spaced far apart from the *next* transmitter

Yes, is by far the stronger signal - the other transmitters are receivable, but variable, and can break up.

I was staying up there, when it caught fire, and the signal went off.

Doesn't necessarily mean that your set wont have two 'BBC1's'

I can definitely receive two transmitters though one is rather weak and in a different direction

It will receive from all three main transmitters, and after a retune, will offer a choice of which transmitter to use as it's local one, but it never then allows you to switch to any none-local transmitter.

Our local transmitter, is the last of the three it finds.

When the white panel appears, asking for the transmitter to be chosen - completely out of the blue, at switch on, usually to watch BBC1, on a morning, I also notice it has somehow switched to the BBC1 north-west transmitter, from the BBC 1 Yorkshire it had been on the, the evening before.

That is a function of the TV software. I've had TVS quite happy to display more than one copy of the same channel

Well it sounds like a crap TV
