The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Mendip (Somerset, England) mast?

BBC channels may vanish from 760,000 homes across Mendip as Freeview stations move to new airwaves - Somerset Live says:

"Further updates at the Mendip transmitter group to move other channels will take place on 5 June and 19 June. On both dates, work will be carried out overnight at the main transmitter and be completed by 6am. Viewers can then retune at any time after this."

Wonder if this will fix things without needing a new aerial?

FAQs here https://www.freeview.co.u…D.97 mentions:

"4) I've retuned but I'm still missing some channels. What do I do?
Carrying out a full retune on your Freeview TV or box should restore your channels. However, in some cases you may need a new aerial to continue watching all available services. For more information or help with this call the Freeview Advice Line on freephone 0808 100 0288. You may be eligible for free in-home support, including aerial work if needed."

Some form of compensation? Who would be eligible?

Gammerx: The retunes in June will see further multiplexes move to new frequency allocations. If you have a fault now, you should contact the Freeview Advice Line, as you have quoted above. Any viewer who has reception issues following the recent frequency change (where there wasn't a pre-existing fault) and who doesn't also have satellite or cables will be eligible to have a replacement wideband aerial fitted free of charge. This must be arranged by contacting the Freeview Advice Line, they won't reimburse you for the cost of having work carried out by anyone else.

Gammerx:

Did you carry out a retune as I advised in my Friday 9.10pm post? Clear the existing tuning, then do a MANUAL tune using the Mendip UHF channels (mentioned again to Brian yesterday).
Current Mendip UHF channels 32, 54, 58, 48, 33, 52, 36, 35.

I think a Manual tune is the answer if people are still finding problems. A lot of the Mendip coverage area is also covered by Stockland Hill and Wenvoe, which confuse many boxes on an auto set up option.

To whom it may concern:

Mendips is still sending out a signal on c49.

1) this is a waste of electricity.

2) My old Sony vcr DOES NOT have a manual digital channel search (it has one for analogue...) which means the auto search always locks on to c49 first, over-riding the new BBC1 channel (c32).
.
Please will someone do something about this??

Brian Newcombe: There's nothing anyone on this website can do as no one here has any connection with any broadcaster or the transmitter company (Arqiva). There are further frequency changes due at Mendip on 15th and 19th June so perhaps the additional mux will be switched off on one of those dates.
