As already mentioned there is Planned Engineering listed for Mendip at present. If your set auto-retuned when signal was interrupted (if it has that function turn it off, it's more trouble than it's worth) or you retuned, then as StevensOnln1 has already said it can clear the correct tuning!

At time of posting Mendip is transmitting at normal power, try a manual tune on UHF channel C32 (the BBCA/PSB1 multiplex) to see if it restores the channels. If you have an HD/T2 tuner and the HD channels are also missing, try a manual tune on UHF C35.

If you still have no luck, as already advised, check connections and check your aerial is intact and still pointing in the correct direction. If you need more help, please provide a full postcode so we can examine predicted reception at your locale.

How old is your aerial?

The Sony Movies Classic channel is broadcast on the Local Multiplex which doesn't have the same coverage as the other main multiplexes carrying other main channels BUT it should still be receivable in most parts of Chipping Sodbury, see Channel listings for Industry Professionals | Freeview for which programme are carried on which multiplex.
As StevensOnln1 has already said we need a full postcode to look at predicted reception in your locale.
The Local multiplex is on UHF channel C30 from Mendip. You could try a manual tune as that may pickup the channel. Auto-tune sometimes misses weaker signals.

If your aerial is an old aerial group C/D then you may have occasional trouble with the main BBC SD channels (the BBCA/PSB1 multiplex is on UHF C32) and may not be able to get the Local multiplex on C30. These days you may need a Group T/Wideband aerial to get all the multiplexes satisfactorily (depending on location).
Do you have intermittent problems with other channels?

There's an OFCOM document with polar diagrams, I see if I can track it down. IIRC there's been no significant changes to coverage apart from where those additional beams were provided.

Just to add to my post on Monday, 15 February 2021, I omitted to note the Local Mux from Guildford on UHF C33.

Try this link https://www.ofcom.org.uk/….pdf

There are two other documents but I think they are just parts of the above. The structure of some of OFCOMs documents has a lot to be desired!

Ian Carrick:

The frequencies you've listed are correct BUT no:8 754000kHz (COM8) is no longer being transmitted, it was closed at the end of June 2020 for commercial reasons.
If you see my post on Monday, 9 November 2020 (at the top of p111 here) you'll see all the correct UHF channels listed for Pontop Pike. If you hover over each of the C numbers it gives the frequency.
Bandwidth is always 8MHz.

For the rest of the information, rather than me laboriously listing them, you'll probably be best putting your postcode in the box at Platform management | Freeview and then hover your mouse over the relevant channel numbers and it give you the transmission modes and powers.

Ian Carrick:

Just to add, the transmission modes and powers are listed at the top of the page but I haven't double checked that all the information is correct and up-to-date as some information on pages on this site has not been fully updated/corrected.

Details of 11B_Bournemouth DAB multiplex
Friday 12 March 2021 11:50PM

Mark Warner:

Too many DAB radios still being sold by such "large grocery" stores are not DAB+, they are plain DAB. If you think you've been "mis-sold" the radio, take it back and ask for a DAB+ exchange or your money back.

Timothy Davis:

The transmitter hasn't been currently or recently listed for Planned Engineering and I can't find any reports of outages. Have you tried a manual retune on C40?
If you've tried that with no success, what signal strength and quality figures are you getting for the other muxes?

Check all your connections and coax plugs for corrosion etc. Make sure your aerial looks intact and still pointing in the correct direction. Check your downlead is secure and appears undamaged.
Problematic connections, water ingress etc. can seem to affect reception of just an individual or several multiplexes.

Have you changed anything in your set up prior to this problem arising?
