The symbol shows the location of the Lark Stoke (Gloucestershire, England) transmitter which serves 38,000 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.

Are there any planned engineering works or unexpected transmitter faults on the Lark Stoke (Gloucestershire, England) mast?

MalcolmW:

Although the site owner has not found the time to make several updates since the 700MHz Clearance program and the "transmission frequencies change over time" section hasn't been updated, the UHF channel list a the top of the page are correct. Lark Stoke's UHF channels are C26, C23, C30, C33, C36, C48 that's in the multiplex order PSBs1-3, COMs4-6. The allocation of programme channels is a bit out-of-date.

GB News is on ArqB/COM6.

See Channel listings for Industry Professionals | Freeview for which programme channels are carried on which multiplex. That list is normally up-to-date.

I am at post code WR11 1YJ in Evesham and do not receive
an acceptable signal level and quality for channels in the COM6
mux during the day. I have my aerial aligned with the transmitter
at Lark Stoke.
I also have an aerial aligned with the transmitter at Ridge Hill which
gives very acceptable signal strength and quality 24/7.
I find this anomaly difficult to asign it to "atmospherics"!!

Well as it so happens if this is a recent occurrence - you don't say how long this has been the case - it could well be Current weather conditions -
Tropospheric Ducting - causing interference from more distant transmitters in Europe or the UK. This can be very variable and is usually short term at any instant but conditions have been persisting for several days, different parts of the UK are being affected at different time. Not every multiplex will be affected, nor necessarily more than one at any time, it will depend on where the interference is coming from.
Both Freeview and the BBC have issued warnings about short term interference to reception.

Although there is some slight variability across your postcode, you are predicted to get good reception from Lark Stoke for all 6 multiplexes, COM6 is only fractionally less good in some spots, in others it could be COM5!
The aerial should be pointing at a bearing of 90 degrees (that's due E) with its rods (or squashed Xs) vertical, although reception can be affected by very local conditions such as trees, other buildings, (any scaffolding or metal chimneys etc) height of aerial and so on.
You don't say how old the aerial is. If it's an old Group A (pre-DSO), it will not have good reception of COM6 on UHF C48, and if it is that vintage, I would question the quality/current state of the coax which could also reduce the strength of the higher frequencies if there has been any water ingress at any time.

Check you are correctly tuned to Lark Stoke's UHF channels as per the post before yours.

Your postcode is predicted to get quite variable (PSBs) to poor (COMs) reception from Ridge Hill, bearing 257 degrees (12 degrees S of due W) with its rods horizontal. A Group A aerial would suffice.
On the other hand, its predicted to get very good reception from Sutton Coldfield, bearing 6 degrees that's just E of due N, with the rods horizontal. A Group B aerial would suffice.
Again reception can be affected by very local conditions.

In all cases a quality Group K aerial will cover all transmitters, although Group T and Widebands can be good enough, it will depend on the particular model of aerial and local signal strength.

I have had reception drop outs for some time (signal quality but not signal strength from Larkstoke), mainly around 5.30 pm during ITV's 'The Chase' for many many years. I live in Warwick, CV344PT.
Retuned many times, amplifiers of many types and roof mast raised. Obviously I could point the aerial to Leamington repeater station for a better signal but that would reduce the number of channels.
Several days ago I retuned during a poor signal occurrence because HD BBC and ITV was not watchable. To my surprise the problem has disappeared from HD. I do note that when in Freeview signal test HD is on programme 47 (682000khz) not 30 as you state on the website.
Any explanation for this would be appreciated.

S. Ayres: From entering your postcode into the Freeview detailed coverage checker, it looks like you're in a slightly difficult location for reception. Lark Stoke is not predicted to give you a strong signal (it's 25km away and only has a 1kw output). It sounds like you've picked up the Leamington Spa relay when you retuned, which broadcasts the PSB3 HD multiplex on UHF channel 47, even though reception from Leamington is predicted to be poor at your postcode. The transmitter coming up with the strongest predicted signal is actually Sutton Coldfield (39km away on a compass bearing of 332 degrees) and your aerial would need to be mounted horizontally with the elements going side to side, rather than vertically (elements going up and down) as it would be for Lark Stoke or Leamington.

Please post a question, answer or commentIf you have Freeview reception problems before posting a question your must first do this Freeview reset procedure then see: Freeview reception has changed, Single frequency interference, and Freeview intermittent interference.

If you have no satellite signal, see Sky Digibox says 'No Signal' or 'Technical fault'

If you have other problems, please provide a full (not partial) postcode (or preferably enter it in box at the top right) and indicate where if aerial is on the roof, in the loft or elsewhere.
