I suggest you re-read my Friday post at 9.10pm - the long one before your last. Especially the paragraph beginning "If you are still having trouble getting all the muxes ....".
Closing down C49 will make no difference. If you follow the MANUAL tuning method I described after clearing the tuning memory by scanning with the aerial unplugged, it should solve the problem.

I'm also reminded by Adrian finding and resolving the cause of his issue with C32 being blocked by an RF modulator, that if you have any RF modulators running from any other "boxes", in the first instance switch them off to see if it solves your retuning problems with the aerial then plugged directly into the device you are retuning. It would probably be best to adjust the modulator channels to ones at the top of the UHF band above C60.

Yes, the channels on this site are currently wrong, please re-read my post immediately preceding your last.
As has been mentioned many times on this board and most other transmitter boards putting your postcode into the DigitalUk coverage checker at Digital UK - Coverage checker will not only give you the current Mux channel allocations, but details of retunes etc. Other pages on DigitalUk and Freeview will give you a wealth of useful information.
The tvchanges page also has some useful FAQs as well as mention of a "Code of Service" and mention of the changes being announced by OFCOM whose site will have lots of background information if you wish to search for it.

Iain Davies:

Your post Mendip (Somerset, England) Full Freeview transmitter | free and easy gives the impression you are an experienced aerial installer, you also made mention of the 2019 retune events in a post prior to that, so frankly I'm flabbergasted that you aren't aware of all the information and support that's available.

The "organisers" haven't shot themselves in the foot at all. As mentioned by StevensOnln1, retune events, 700Mhz clearance etc has been well publicised over recent times as well as the potential need for a new aerial. In the last few days before the retune(s), there've been on screen messages.

FYI in the analogue days when Channel 5 started up it's UHF allocations were typically C35/C37 indifferent parts of the country. With it being C37 at Mendip, there were "Enhanced" C/D group aerial produced to give improved reception of C35/C37. I guess it probably made them a bit like a Group E.
Anyone with one of these may not have any particular problems with the retunes. But as mentioned in previous posts, help is available from Freeview.
I would guess that C49 will remain on air a while, to give those having problems with C32 chance to contact Freeview for possible help with an aerial upgrade.

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…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.

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.
