StevensOnln1:

Thank you very much for the feedback. The aerial in use has been in the loft for at least 10 years, so maybe a new purchase for a wideband aerial is needed.

Interested in what you said about contacting Freeview advice line as I don't have satellite or cable, just Freeview.

Will let you know how things progress, especially in the light others are complaining about the same problem.

Gary Colby: Details of the Freeview Advice Line can be found at the link below. You should be eligible for a free replacement wideband aerial if you don't have cable or satellite and are unable to restore the channels you've lost via manual tuning.

Gary Colby: Just to add what has already been said, you shouldn't have any trouble with reception once your aerial has been sorted. AFAIK there's no new buildings in the Concorde Rd area of the trading estate that might obscure the signal, and especially as you've implied you aren't having any issues with the other UHF channels from Mendip.

I live near Dursley, north of Bristol, and manually tune my devices to avoid picking up Welsh channels.
Recently i've noticed a problem with no signal on the bbc news hd channel 107. This is on 2 Panasonic tvs and a panasonic hdd recorder. Ie none show 107. However, a talktalk youview box which was tuned automatically does show107.
This website shows 107 being on channel 33 or com 7, but there seems to be a big discrepancy between the stations you indicate here and what i actually got after factory resetting and manually tuning to the channels you list for the mendip mast. Eg 107 and 108 et al are not picked up but 12 which should be on 56 is.
Is your lusting up to date and should i be tuning into other channels?

All the advice regarding loss of comm 5 ,is nothing related to the aerial size . modern sn=mart tvs tune automatically to the strongest signal ,when they retuned the signal to 33 it fell below the auto scaning range. so you cant receive sky new ,pick etc.

the fix is simple and cheap go to the tv manual setting and search for 33 then it will restore the lost channel.
I spent a lot of time any money changing aerials to no avail from advice from this site.

phil : Manual tuning will only restore the missing mux if you have a strong enough signal, although it is certainly worth trying. Many viewers will require a new aerial, which should be available free of charge to those who don't have satellite or cable.

Since com7 has gone to ch 36 I am having problems with it pixellating and sound cutting out when checking the signal on my you view box it was a lot weaker than ch 33 and ch 35 is the transmitter output on ch 36 at much lower power than the other two thirties channels.I can see the mendip mast on a clear day from my downstairs lounge window and have a professionally installed log periodic roof aerial. my postcode is np11 6qx.
