I am missing a transmission multiplex?
Brian Butterworth published on UK Free TV If you are missing a single multiplex on a single frequency, it may be that you have a local source of interference - such as a VCR, games console or Sky Digibox - causing the problem rather than a poor signal from the aerial.
Try eliminating any such devices, and if one does appear to cause the problem, change it's RF output channel to a new value.

Hi, I'm trying to sort my mum's TV... She is based in Felbridge and cannot get PSB2 on the lounge TV, but can in the kitchen. Previously she has had ITV etc, it has just disappeared. It's a Sony Bravia TV, she doesn't have sky etc. ive re-tuned, unplugged Arial etc... When we put a different TV onto the aerial we can pick up ITV, Channel 4 etc.
Any suggestions greatly appreciated.
Many thanks

Jo: If the kitchen TV can still receive PSB2 when connected into the lounge TV's aerial socket, then carry out a manufacturers reset on the Sony Bravia in order to correct the glitch in the tuners memory, this procedure also known as "default setting" or "first time installation".

Hi
I am having trouble receiving certain channels on my Sony Bravia TV. I've done multiple channel scans and sometimes I get 100 plus channels but mostly get about 58. I have investigated and believe it is certain multiplex's that I cannot get. Of the BBC channels i can presently get BBC 4 HD and BBC News but not BBC 1, 2 etc. I have done a factory reset on the TV. I've checked that the transmitter ( Sutton Coldfield) is working correctly and it is. My cable from the TV to the wall socket is gold tipped and only about 3 years old.
I've also switched the TV off, unplugged it and taken out the cable and then done a scan without the aerial cable plugged in, then tried again with it plugged in ?.......HELP :-)

Hi Guys
I have this weird problem again where I lose all channels on com4. It seems to start going off about the same time every year (Mar/Apr) and then the same time every night (its around 8pm at the minute). However, as the year goes on, the time it goes off gets later. In total, this lasts about 6 months, after which everything is fine again. I live in Gateshead (NE10 8JP) and on the Chatton transmitter. Any help would be greatly appreciated.

Ah, this thorny old problem again. We did a thorough analysis of this almost a couple of years back. We did ask/suggest a couple of things to which we didn't get a response from you. The last post from me was -
https://ukfree.tv/extras/inreplyto/1050243
Now whilst I said what I did about the trees, it's possible that your reception of the SDN mux on C29 is sufficiently marginal, which if you recall is predicted to be the worst in your postcode, that the addition of some tree growth and the slight change in propagation conditions as dusk, is enough to make a difference, possibly coupled with some interference which wasn't identified.
I remember commenting about the lowish signal strengths and not knowing anything about your aerial installation. I didn't see any additional information about this other than it was put in by an installer. Where is the aerial located, is it external?
If perchance they installed a Group B aerial, it won't perform well for the SDN and ArqA muxes.
I did suggest you have a chat with neighbours whose aerials point at Pontop Pike - compass bearing 242 degrees (almost WSW) and those at Bilsdale - compass bearing 158 degrees (almost SSE) to see how reliable their reception may be. Did you discover anything?
Now, on the subject of interference, you did mention a 5G mast not too far away. I'm not too sure why we didn't pursue this, maybe at the time your postcode wasn't sent postcards by Restore TV, but just checking, it has now.
See https://restoretv.uk/postcards-not-sure/ and put in your postcode.
Dealing with this potential (even likely) issue first would be the next best thing before doing anything else.
Contact Restore TV and tell them you keep having intermittent interference problems (I wouldn't elaborate on when etc) other than its been for over about 18 months or so, and you understand that postcards have been sent (though you don't recall seeing one - or did you?) and say you understand they can supply a Free Filter to eliminate any interference from Mobile masts.
Let us know how you get on.
