The symbol shows the location of the Sandy Heath (Central Bedfordshire, England) transmitter which serves 920,000 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 Sandy Heath (Central Bedfordshire, England) mast?

Sam: Well Sandy is located at 28 miles @ 133 degrees from your location whereas with Suzy its 20 miles @ 37 degrees, so your problem isn't necessarily directly linked to Suzy's unless through the possibility of atmospheric conditions applying in both cases.
Of course in cases where reception problems are suspected of being caused by external reasons, although I fully understand peoples reluctance into taking this action but making an enquiry with someone that lives reasonably nearby is really the only way of finding out for certain if the problem being experienced is common to the area, and in your case it would be particularly interesting to know if the resident of the third house up (white door as well as panel above) from the very end pebble dashed one is also having problems with Sandy, as their property appears to be fitted with a Log 40 aerial pointing towards Sandy, these aerials being a good standard to judge reception on whereby if they are having problems then anything will.
By the way a Log 40 aerial does not have a reflector on its rear and tapers inwards towards the front.

I would be interested to know how many people are experiencing single RF channel interference. i.e. problem receiving all the logical channels on the same RF MUX frequency. I would like to establish if the reported problems are due to weather and time of day related co-channel interference. Should this be the case no amount of adjustment of the receiver or aerial is going to improve the situation.
Such interference is characterised by a high signal strength, which may change rapidly in value, and poor quality as measured by bit error rate.
Symptoms include picture freeze, pixelation and breaks in sound with associated pops and squeaks.
The tuning menu of most TV sets allow the user to check both the signal strength and quality on a scale of 0 to 10. This menu option also displays the frequency and/or RF channel number.

jb38: Hi again, i will try a signal booster as this is driving me round the bend, even though i like watching the Olympic ( not much choice really ) i am getting a bot board with it and i miss my programmes from Really, Pick tv etc, but do you think a booster will help ? if it pours down with rain i have a great picture but for the past few days ive had nothing at all on those stations :( i just cant understand the weather causing so much trouble with my viewing . so will get a booster like you said if it doesnt work i can always return it lol thanks again x ( oh cut down a lot of those trees that you see on google, but cant cut down the ones surrounding the property as they are council ) lol

Had a look at the signal booster in argos, i will also have to get an aerial extension and if my outside aerial goes into that i will need something to run from that to the digibox i will see how it goes x

Suzy: Yes, give it a try as you have nothing to lose provided that you do not damage the packaging and have kept your receipt safely away.
By the way, test it out by first of all selecting a channel on your TV and checking the results "before" connecting the aerial to the TV via the booster, then once connected via a jumper lead from the boosters output to your TV and the aerial straight into the booster, set the booster at just above zero indication making sure the reception was still as before, if not advance it until it is, then if the channel is suffering from intermittent freezing etc try "slowly" advancing the booster whilst observing the picture for any improvement.
I do have to say though that although these boosters can in many cases make a vast difference to reception its in situations where although the signal level received is maybe dropping off in the evenings resulting in pixelation etc, that although the signal might well be at a lower and critical level its "not" of an erratic nature as far as quality is concerned as virtually nothing can compensate for that, and of course trees are notorious for causing that type of problem.

after retuning again today 24/08/12 , as do every morning , find reception totally useless . it was much better when on analogue . all system components are fine . why should we have to have satalite to get a decent t.v. service ? we pay full license fee for around 25% of the service . try reporting , but , fulls on deaf ears .

I live in Stilton and for the last 2 days have experienced signal loss or signal delays( picture freezes for a second) constantly on ITV, channel 4 & 5. Have tried retuning etc but still the same. Have checked with someone else in my village who I know is on freeview and they're experiencing the same problems. It's starting to make these channels unwatchable with all the jumping etc.

Claire: I live in the Stevenage area and receive Anglia TV. Since Saturday evening September 1st at about 7pm the signal started breaking up and the picture was blocking. This lasted until about 10pm. This problem only affected ITV1. I did a reboot on the TV and Freeview box but this made no difference. Again last night at about 7.50pm the sanme thing again. I know it is not my box of TV as my second TV was the same. I live in a block of flats which has a communual aerial. What can I do as my reception on this channel is unwatchable.

I have had similar problems on Sunday evening,with Sandy Heath on ITV1 Ch4 and 5.
Signal strength very good 84%(as normal) quality 100%(as normal) Humax Fox T2, Loewe TV and Panasonic TV.
Could well be a transmission issue on this multiplex as there is no indication that the signal is poor.
