The symbol shows the location of the Carmel (Carmarthenshire, Wales) transmitter which serves 72,000 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 Carmel (Carmarthenshire, Wales) mast?

Is there a weak signal to the Carmarthen area as the free view reception has been very poor for a few days. Thanks

Roger Owen: Hi, Roger.There are no reported issues on the Carmel transmitter but a retune may be necessary on your tv because Bay TV for Swansea may have been added to Carmel possibly. Richard, Norwich.

I have a 5 year old technika TV which, as of about a week ago, looses the signal about 4.30pm and even though I am not using any new equiment near by it takes several attempts to retune it and then it is "temperamental" pixilating until about 7pm when the signal goes up to 100% again. Is it my TV or does anyone else have this problem? Do I need some sort of booster?

Gill: There could be two possible reasons.
1) Your suffering from whats called 'single source interference' - you've got something like a thermostat or something with a timer, which comes on and causes interference. Search for that phrase on this site, and it should offer some ways to find out if you have, and what you can do about it.
2) You've just go a problem with your aerial, which just happens to act up at a time you notice it. Check your signal strength - if its very low, then there is a problem somewhere along the chain from the aerial to your TV. Could be a simple as a dodgy aerial lead in the back of the set - they are very cheap, and easy to replace, so at least you can check it. Remember that none of us check signal strength much unless there is a problem - it tends to work or it doesn't. And if thats the time we happen to be watching it, then we'll assume it only problematic at that time. Rain can get into the joints, kill a signal, and then dry out, and everything is fine again, but at some point, thats going to happen again.
3) Your getting 100% signal? See 'too much of a good thing' on this site for further info - 75% signal strength is perfect. If you can supply a postcode, we can see if your getting too high a signal.

Gill: The timings of the symptoms referred to would suggest that the problem is likely being caused by some form of localised interference, for example such as a neighbours washing machine, worn / sparking motor brushes in same being notorious for causing problems of this nature, other potential offenders in this respect being vacuum cleaners or sewing machines, or indeed any domestic device fitted with a brush type motor can be a potential source of interference.
Should you reside in a property with a neighbour through an adjoining wall? a good way of checking for interference from motorised equipment is by using a transistor radio fitted with a LW band. The procedure being to tune the radio to above where radio 4 LW is received (198Khz) followed by advancing the volume until background mush is audible, if you then position the radio close to the adjoining wall (preferably near to a power socket) shortly prior to when the interference is known to start, said interference if originating from a faulty device in a neighbours property will show up on the radio as a loud raspy type crackle.
This test also works on FM radio's tuned "not" to receive a programme, although the interference referred to shows up as a high pitched raspy noise above the background hiss.
Devices used to extend the range of WiFi etc or cable boxes used by Virgin and such likes are also potential sources of interference with reception, although in this case its somewhat more difficult to determine if the use of such equipment is responsible or not except to observe if said interference ever occurs when the neighbour is not at home.

I am not far from the transmitter less than eight miles I can't get a signal on my indoor Ariel that has a 40 miles range how near do you have to be

Martin morgan :
Indoor aerials rarely give useful results in my extensive experience. It's a question of signal strength, not distance. 8 Miles from a smaller transmitter could well be too far away. If it is a main transmitter it could still be too far. You're better off with a properly installed roof aerial of log-periodic design.

You say there is no engineering work going on, yet the last few days, channel 4 and ITV have been off for longish periods in the evening; and today it is the turn of BBC channels to be down - no 10pm news as well as premium programmes at 9pm. (I don't watch continually)

Glyn Taylor: Engineering work is not generally undertaken in the evenings as at this time of year it would be too dark for the engineers to see what they are doing up a transmitter mast and it would generate thousands of complaints from people finding their prime time viewing interrupted. It's far more likely that you're either suffering from some kind of interference or there is a fault with your aerial system. Start by checking for any loose or damaged cables or connections. Does the loss of signal coincide with your central heating turning on or another device with an electric motor (e.g. washing machine, tumble drier, powertools, etc) being used?

Hello,
The TV set utilizes digital terrestrial signals from the Carmel transmitter but it has not been receiving any programmes for some days now. (I'm not sure exactly how many days the problem has been happening because the set is in a bedroom and we only use it occasionally.) I've tried the auto-tune procedure a few times, using first an external aerial and then an indoor one, but no stations have been found. The TV is a very old Sony pre-HD model so could this be an indication that there is a problem with the set?
Thanks for your help.
