Don't forget they're only predictions. Get your installer to check the actual received strengths with his meter - actually the same goes for Mendip, sometimes a skight tweak of the aerial can make a difference.

Mendip transmitter
The LBS station for 'Bristol TV' given above as C51 714MHz seems to be in error and out of date.
Currently available as multiplex C30 546MHz and tuning station 7. Agreed?

Correct. As has been mentioned several times around this site and now several pages back for Mendip, the site owner has not had time to keep up with the many changes resulting from the 700MHz Clearance programme and this is one of the errors, although the Local mux was recently mentioned just a couple of pages back.

I listen to Classic FM on my LG TV; I live in an apartment and the aerials here are up in the roof space of the building, and cannot be accessed, or tweaked, by residents, only byengineers. The reception of Classic FM frequently breaks down or disappears; I re-tune frequently, last time, 30 minutes ago. Also removed aerial and did another auto retune.. Classic Fm restored, but reception not the best. I live in Mi nehead, postcode TA245DA. I have checked and there are no current engineering works, or known problems. Do you have any suggestions for what else I can do to ensure my reception of Classic FM remains constant, and enjoyable. I have similar problems with Golden Days Radio, which I listen to on my TV, via the internet.
With many thanks for any help you are able to give.
Regards

The Mendip transmitter isn't currently listed for Planned Engineering and I can't find any current fault reports and the BBC haven't reported any problems with their multiplexes recently.
Classic FM is carried on one of the Commercial multiplexes (ArqA/COM5) see Channel listings for Industry Professionals | Freeview for which channels are carried on which multiplex.

Now, reception in your locale should normally be extremely good, however you could receive signals from Wenvoe (and only the PSB muxes from Carhampton) so check in your TV's tuning section that Quality is 100% and the Signal Strength is high for each Mendip multiplex - as follows -
Mendip's correct UHF channels are C32, C34, C35, C48, C33, C36, C55, C30. That's is the order PSBs1-3, COMs 4-7, Local mux. You probably don't get the Local Mux as you aren't in the correct area. (There's a slim chance you might get a Local mux from Wenvoe on UHF C37 but this will also be very dependent on the aerial set up in your building!).

Further advice, STOP retuning! There is no point in doing that, if there is a problem with a signal, whether it be due to Planned Engineering, weather conditions affecting signals, transmitter faults or aerial system faults then most times all it will do is clear the correct tuning. The only time you need to retune these days is if you get an on screen pop-up because a commercial channel has moved multiplex or a new one has been added (you may get an on-screen message that programme mapping has changed).

If you are not getting 100% Quality on all multiplexes virtually all the time (there's the possibility of some temporary disruption due to current weather conditions) then check with a neighbour if they are having the same issues and if so, complain to the building management that there's an issue with the system.
If you have problems with Internet radio as well it might be worth checking your TV's sound settings in case some thing else is amiss. Also check on a computer or other device, it could be your internet connection being poor.
