Barry kenneth Richardson:

Can't find any faults listed at present and it's not listed for Planned Engineering at this time either.

Have you checked that your aerial is still pointing the correct direction with its rods (or squashed Xs) vertical.
Check all your coax connections behind the TV etc.
Do you have any form of amp or distribution amp?

Another possibility is there is some tropospheric ducting/temperature inversion around which can be causing interference from other transmitters (continental interference in old money)!
But that doesn't usually carry on for length periods affecting all multiplexes and there's nothing you can do but wait for it to clear.

Have you signals returned yet?

David Thomas :

It'll most likely due to the terrain in your location especially if you are in a valley, and you get signals from a relay "Light" transmitter which only has the 3 main PSB multiplexes. Relay transmitters often only serve small communities and the commercial operators don't consider it cost effective to pay for the extra transmission equipment.

If you provide a full postcode we may be able to advise if there's any possibility of getting signals from another transmitter.

Yes there is "tropospheric ducting" around affecting reception in various parts of the country but especially the south coast at present.
You won't have "strayed" to Margate as it operates as a SFN with Dover (along with Ashford) on all channels (that's a Single frequency Network - for each multiplex) since October 2019.

You should still be correctly tuned unless you've tried retuning which is something you should never do when you have weak or pixellating signals due to weather, engineering or faults as invariably it just clears your correct tuning and you have to retune again when signals are normal.

The UHF channels you should be tuned to are C33, C35, C36, C39, C42, & C48
That's in the multiplex order BBCA/PSB1, D3&4/PSB2, BBCB HD/PSB3, SDN/COM4, ArqA/COM5, ArqB/COM6

All:

Just a reminder -

In the multiplex order BBCA/PSB1, D3&4/PSB2, BBCB HD/PSB3, SDN/COM4, ArqA/COM5, ArqB/COM6
The UHF channels you should be tuned to are C33, C35, C36, C39, C42, & C48
A Group K aerial is required (though Group T/Wideband should suffice depending on location, in strong signal areas some may get away with some Group B aerials, but not recommended).

Also note that Margate and Ashford operate as an SFN with Dover, and also there is NO Local multiplex.

Just to update information here, Margate is longer a "Light" transmitter and has transmitted all six multiplexes as an SFN with Dover since October 2019.

I see Mendip is still listed for Planned Engineering, but information on Engineering work isn't automatically coming up on Transmitter pages.

Craigkelly (Fife, Scotland) transmitter
Thursday 4 August 2022 5:27AM

Graham Webster:

I think there's been some confusion here, no doubt not helped by the channel listing at the top of the page having an error as well as the "change over time" section not being updated as the site owner has not had time to do all he changes since the 700MHz Clearance and COM7 closure.

Ideal World LCN51 is carried on COM6/ArqB and is on UHF C37 at Craigkelly.
See Channel listings for Industry Professionals | Freeview for which channels are carried on which multiplex.

In the multiplex order BBCA/PSB1, D3&4/PSB2, BBCB HD/PSB3, SDN/COM4, ArqA/COM5, ArqB/COM6, Local
The UHF channels you should be tuned to are C27, C24, C21, C29, C31, C37 & C32.

Depending on your Location, you may/may not receive the Local multiplex.

Just to add to the complexity, Craigkelly is currently listed for Planned Engineering with "Pixelation or flickering on some or all channels".
There is also some "Tropospheric ducting" affecting reception in different parts of the country at differing times, this can result in interference from distant transmitters in Europe or the UK although this is mainly affecting the south of the country at present.

Divis (Northern Ireland) transmitter

hsrrysmyth:

Sorry, your assumptions are incorrect.
The Divis transmitter isn't currently listed for Planned Engineering, but the lists aren't always 100%.
There are no current faults listed by the BBC that I can find either.
There has been some "Tropospheric Ducting" with the current weather conditions which may have affected reception recently, and predicted that it may do so again at the weekend in your area.

Have you checked that your aerial is still intact and pointing the correct way?
How old is your aerial roughly? Is the downlead undamaged and not flapping in the wind?
Have you checked the coax connections behind your TV?
Do you have any amp/splitter, if so is it still powered and functioning correctly?

The transmitter power since DSO is 50kW and comparable with many other UK main transmitters when comparing Digital to Analogue, many of which have improved coverage.

If you provide a full postcode we can check your predicted reception.

Wendy Barnett :

You shouldn't need a "special" aerial, but what sort of aerial is it, is it external or is it a set-top?
Apart from trying to describe it, see if you can find an internet picture of a very similar aerial and post the link.

The aerial should be pointing virtually due South for Caradon Hill with its rods (or squashed Xs) horizontal, and you should get excellent reception of the 3 main PSB multiplexes (those carrying BBC and ITV/Ch4/Ch5 and some of their sister channels), reception of the commercial multiplexes may be variable, there is no "Local" multiplex.

See Channel listings for Industry Professionals | Freeview for which channels are carried on which multiplexes.

Is there any close-by obstructions on the line of sight - eg. another caravan directly in the way or is the aerial height above them?
If there are obstructions then you could try to get signals from Huntshaw Cross which is bearing 57degrees, that's 12 degrees E of NE at your location. PSB reception should be good, but the COM multiplexes are likely to be more variable.

If there are local obstructions you need to get the aerial height above them.

in the multiplex order BBCA/PSB1, D3&4/PSB2, BBCB HD/PSB3, SDN/COM4, ArqA/COM5, ArqB/COM6

Caradon Hill's UHF channels are C28, C25, C22, C21, C24, & C27
Huntshaw Cross UHF channels are C30, C31, C37, C32, C34, & C35

Check in your TV tuning section you are tuned correctly. If not clear current tuning by doing an automatic tune with the aerial unplugged, then plug it in and do a manual tune for each channel.

You'll have to contact the station and ask! As this isn't their website, they won't see your comment here.
