MikeP: My Sony PVR does - it just scans twice a day, and then gives a message along the lines of 'new channel added'. I suspect its an automatic feature on most TV's, but its not always enabled. On the other hand, the Manhattan HD box doesn't seem to. I can't speak about my LG TV, since its a little older, and since we tend to use the HD box with it, I havn't noticed if it updates itself or not.

As stated, my LG does not automatically update either Freeview or Freesat services so I have to do an update when the TV detects changes. It gives me a notice to that effect. I understand from others that this is more the norm than TVs automatically updating, which could be quite annoying if it happens while you are watchoing an interesting programme - a bit like the default behaviour of Windows 10 updates unless you change the default settings.

My ITV (and all PSB2) channels have lost power since yesterday, and these channels are not viewable. My neighbours report the same problem. All other channels are fine. Resetting channels has no effect. The transmitter at Beckley (Oxford) reports no faults. What now?

The D3&4 mux on C60 is the most sensitive to 4G interference -
To check for possible 4G interference see at800 | 4G & Freeview | 4G Disruption | 4G Filters | at 800 MHz
but it is also the highest frequency which tends to suffer attenuation from aerial condition, leaves on trees, moisture in downlead etc...

Are there any issues with Oxford today. Last night all muxs from 4 to 8 disappeared. 4 to 6 returned this morning. Currently LOX - C29; Com7 - C31; and Com8 - C37 are all missing on my TVs. As these are all low frequency transmissions this would mean it is not a 4G issue.

Adrian Crafer: Hi, Adrian. I have just checked and there are no faults or engineering work on Oxford today. Oxford still has high atmospheric pressure, 1023 millibars this morning, and so you may be experiencing the disruptive effects of high atmospheric pressure conditions on your television sets. Lower pressure weather systems have been forecast to be coming in by Saturday, and so your tv viewing will hopefully be back to normal by then. Don't do any full retunes, because your sets will 'forget' the details of the channels you were receiving ok before the high pressure set in! Richard, Norwich, Thursday, 9th. June at 09:40.

Richard Cooper: Thanks for the suggestion. I am sure somewhere in the past someone (possibly BBC Engineering) said that one of the virtues of Digital TV was that atmospherics would be a thing of the past!

Adrian Crafer: Hi Adrian. I don't dispute what may have been said prior to digital switchover, however, many of the posts on ukfree.tv this week have been testament to the fact that Freeview has been susceptible to atmospherics! Richard, Norwich. Apparently the atmospherics problems have peaked now and low pressure systems are on their way by Saturday, by which time normal reception should resume if the weather forecasters are correct! Richard, Norwich.

Adrian Cafer: Nobody claimed that temperture inversions would be a thing of the past, but what you dont have so much of now is the way in which say French Tv channels would intermingle with British ones. I grew up on the South coast, and that was often a problem. With digital, you can pick up other transmitters, or even lose that transmitter entirely, but overall its less bad than it was.

For the last month our freeview channels have dropped in and out like a yo-yo. We have BT TV , Broadband and phone line. The problem affects both the TV in the living room and the TV in the main bedroom where we also have a signal booster. There are building works 400 metres away but there is no notification of any BT engineering works on their site. I thought it might be 4g interference but why has this started so recently.
Any advice, Im in the process of complaining to BT because we aren't receiving our contracted services.
