Malcolm Brooks: Well that possibility always exists as general warnings of a weak signal have been published, although should this be applying then when you go into the manual tuning menu on most devices as soon as you enter the channel number you intend to scan into the box provided the signal strength its being received at will immediately appear before you scan it, so does nothing show when you are at the pre-scan stage?

jb38 - Thank for your reply.
When I go into manual scan I get 61,58,54,48 and 52 - all showing 100% signal strength, but no 56. Maybe it is something local. I live in an apartment block, so will get the management agent to check out the incoming transponders here. Seem to remember a problem when the last stage of the switchover was made, but all channels re-appeared then, after a week on their own. Thanks again.

Malcolm Brooks: I'm also experiencing as you've described (no-show on C56 only). I'm on the west side of Swindon (limit of Mendip coverage), so it could be a maintenance issue as I could receive all muxes prior to the freq change & power boost.

Just retuned my mico stb231 freeview box and notice that bbc3&4 are flaky now, is there an obvious reason for this. All station that were flaky before pwr increase now seem to be stable.

Hi, I am wondering if the channel list above is correct. It is showing Really as on CH 52, when I manually tune CH 52 it does not appear but does on CH 56. I am at BA22 tuning in to Mendip.
Thanks
John

John: Clicking the link next to your posting for Digital UK Tradeview confirms that the above is in fact incorrect. ArqA is on C56 and ArqB on C52, and not the other way around as shown.

Absolutely dreadful reception all week, even worse today, breaking up so much I really cannot watch anything at all.
We are in BA1 1US Bath.

Sorry, pressed enter before I'd finished! I have re-tuned 2 or 3 times each day this week, and just finished again. Utterly ridiculous.

If you look at the bit just above the map of the mendip coverage area map, you can see that there is engineering work taking place and that mendip is subject to weak signals. I live in BS22 in Weston-super-Mare and have had a very poor signal strength all week. But I've heard from one of my dads mates who is in the aerial trade that it should all settle down by the end of Friday.

so that's 2 weeks without a decent signal? Oddly enough, the signal may be terrible, but since the last tune-up we have a few more channels like Quest - all terrible reception too of course; this happen just after Xmas when the wind blew the aerial about a bit. I think 2 weeks without being able to watch a TV I pay a license for, without any explanation (other than on here, not everybody in my building has a computer - many are old and frail and rely upon their TV)is ridiculous in this day and age. Thank heavens for TV Catchup!
Going to get the landlord to send aerial people out anyway, make sure the aerial's in the right position yet again.
