Since the retune event on the 17th the UHF channels used at Kilvey Hill are 21, 22, 24, 25, 28 & 34 for the local mux. C27 is the HD(T2) mux. C37 is the local mux from Wenvoe.
I'm not familiar with your card & software, but based on the list you've posted, those are not all the correct channels.
Put your postcode into Digital UK - Coverage checker it will indicate predicted reception at your location. I assume you have a group A aerial set with vertical polarisation if Kilvey Hill is your intended transmitter, however with recent weather & propagation conditions, you could well be receiving channels from a number of other transmitters some of which might cause interference to channels you want. (You can of course use a Group K, T or Wideband aerial instead of Group A if you want!).
If you only want Kilvey Hill, you need to configure your system (however you do that) to receive
C21 (474Mhz) for BBCA, C24 (498Mhz) for D3&4, C25 (506Mhz) for SDN(COM4), C22 (482Mhz) for ArqA(COM5), C28 (530Mhz) for ArqB(COM6) & C34 (578Mhz) for the Local Mux. If your card will do HD (T2) then C27 (522Mhz) for BBCB (HD) mux.
Remember that C37 (602Mhz) is the Local mux from Wenvoe.

Hi,
Since been asked to retune on the 17th I only seems to get 22 tv channels.
I leave in EX34 9AY and always got the tv vis Kilvey Hill. I am not able to touch teh aerial as I leave in a block of flat.
Any advice as how I can get all teh channels missing?
Thank you

Checking the expected reception at your l;ocation shows that you should be using the Ilfracombe Freeview Light transmitter, see Coverage Checker - Detailed View Reception fropm Kilvey Hill is shown as being very poor.
Please check what multiplex channel numbers you are receiving, Ilfracombe uses 33, 36 and 48. Kilvey Hill uses 21, 24, 27, 25, 22 and 28 but you are unlikely to get much in the way of reliable reception.
As Ilfracombe is a Freeview Light transmitter, you appear to be getting all the correct channels.

I wasn't going to post in response to regis as yours seemed to cover it until my brain registered "block of flats" as I was about to close the page. I suddenly thought that as you correctly mention Ilfracombe is a Light Transmitter this could well be a customised installation & distribution system to receive Kilvey Hill to give more choice, and if it's a channelised system that could be why less is being received. On the other had an automatic tune may have just picked up the strongest channels, it depends on which ones are missing.
regis:
I would unplug your aerial and do an automatic tune - this will clear the set of any previously stored channels. Then do a manual tune of UHF channels 33, 36, (&48 if you have HD) which would be Ilfracombe and give you your local Westcountry news, then UHF channels 25, 22 & 28 for COMs 4/5/6 which would be Kilvey Hill and are unlikely to give reliable reception BUT that would depend on your block of flats installation which you'd have to contact your landlord about if you continue to have issues - you'd need to do that anyway if it's the BBC and main ITV channels that you are missing. Which way is the aerial pointing and is it vertical or horizontal?

Regis and all:
If you received Kilvey Hill before, it should still work on the new channels. A clean retune, as recommended by Chris, will delete redundent channels and select the new Kilvey Hill channels (21,22,24,25,27,28). If your aerial is vertical and points at KH, you might receive a better signal from Carmel (channels 21,22,24,25,27,28) with the aerial horizontal, but pointed roughly in the same direction. I can receive both KH and Carmel, the latter being more reliable, although both can be affected by the 7meter tidal range in the Bristol Channel. Note that the new Ilfracombe relay channels are now the same as three of the new Carmel channels, so, despite opposite polarisation, interference might result - as we had some years back :-( If you can receive Ilfracombe (aerial vertical) it only offers the three main multiplexes, not the full complement of six as from KH and Carmel, but it is good for Southwest news. For all the new channels, a wideband aerial would be the most reliable. A Group-A aerial would struggle with the Carmel Arqiva-B multiplex. If you are able to tune channels in *manually*, you can select the channels you want, with six multiplexes from Wales, possibly plus BBC and ITV Southwest from Ilfracombe. If you use the automatic tuning option, in its inscrutable wisdom it will probably select weaker channels... Fallback position : forget the Ilfracombe relay and manually select either KH or Carmel and get SW news via the internet. Hope this helps!

Chris.SE: I have edited the config file in Kaffeine Kaffeine - LinuxTVWiki and still cannot receive BBC4 SD (My computer card is not an HD card ) I have no trouble on either of my TVs after retuning. I have 95 channels which is quite a few less than my TV has found. Does it make a difference if I scan when BBC4 is not broadcasting ? Here is my current config file :
[dvb-t/uk-KilveyHill]
T 474000000 8MHz 3/4 NONE QAM64 8k 1/32 NONE
T 482000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE
T 498000000 8MHz 3/4 NONE QAM64 8k 1/32 NONE
T 506000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE
T 530000000 8MHz 3/4 NONE QAM64 8k 1/32 NONE

John P: "Does it make a difference if I scan when BBC4 is not broadcasting ?" Very likely you'll get CBeebies during the day instead.
I think this is correct:
[dvb-t/uk-KilveyHill]
T 474000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE /ch 21 BBC A
T 482000000 8MHz 3/4 NONE QAM64 8k 1/32 NONE /ch 22 ARQ A
T 498000000 8MHz 2/3 NONE QAM64 8k 1/32 NONE /ch 24 D3&4
T 506000000 8MHz 3/4 NONE QAM64 8k 1/32 NONE /ch 25 SDN
T 530000000 8MHz 3/4 NONE QAM64 8k 1/32 NONE /ch 28 ARQ B
T 578000000 8MHz 3/4 NONE QPSK 8k 1/32 NONE /ch 34 Kilvey Hill (Local Mux)
T 522000000 8 MHz 2/3 NONE QAM256 8k 1/32 NONE /ch 27 BBC B HD

John, as nobody says, you might get CBeebies, but during the day the LCN is normally populated with a data stream and I'm afraid I haven't a clue how you card handles them but I guess nobody may know ;)
My only experience with a "box" that didn't handle such streams was that is ignored/failed to find the LCN. (IIRC I had to do an "add" channels when it was broadcasting - that method doesn't work/not available on all devices).

Thank you. Could someone tell me what is the significance of the 2/3 or 3/4 as I had some of these different in my config file and they seem to work OK

HI,
Thank you for all your comment, unfortunately I cannot do a manual scan as I use a bt box (humax) and it does not have the facility.
I seems to have try everything , factory reset the box and all but still only 43 channels showing (14 of are actually radio)
I am not over technical like some of the comments you mentioned so may have to try to see if I can get someone to look inot it.
Cheers for all your answers and help
