The symbol shows the location of the Sutton Coldfield (Birmingham, England) transmitter which serves 1,870,000 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 Sutton Coldfield (Birmingham, England) mast?

David Luckman: The digital UK postcode checker gives a prediction for Bole Hill and Emley Moor at your location after switchover. I can't help wondering if at present you may be receiving enough signal from Nottingham/Kimberley on C34 (analogue Channel Five) from behind the aerial to block the low power HD signal from Lichfield as you appear to have a good line of sight to the North. It might be worth waiting until 13th April 2011, when analogue signals are switched off at Kimberley, then having another look for the HD Mux.Also check for VCR or Sky boxes with the RF modulator set around C34.

Hello,
Have lost digital signal since Friday (I also experienced long outages in the previous week, but these were due to "engineering work"). Analogue is extremely snowy as well.
Roof mounted High Gain, wideband aerial (300 deg bearing), CV21 1PH.

This morning I have digital back, all be it low quality. I have listed my reported Quality and strength for one channel from each mux
BBC1 q=10 s=7
ITV1 q=4/5 s=6
ITV3 q=6 s=6
BBC Four q=2 s=5
Pick TV q=0 s=4
Film4 q=2 s=4
(before the weekend I used to get q=7-10 for nearly all channels)
Could my problem be due to Sandy Heath being switched on, and should I perhaps turn my aerial to point that way (regional programmes will be wrong, but better than nothing at all)?

When I use the post code checker I get the following list
Sandy Heath - 74.4km 46.2 miles
Ridge Hill - 98.9km 61.5 miles
Waltham - 54.4km 33.8 miles
Oxford - 67.2km 41.8 miles
Sutton Coldfield - 46.2km 28.7 miles
Is the order in best signal to worst signal? Its not distance and its not alphabetical. If it is based on signal then I guess I have answered my own problem, and assume Sandy Heath (best?) signal is swamping Sutton Coldfield (worst?).
Can any body confirm my conclusion. I don t like heights, and dont want to go up ladder unless I have to!

Alan T: Don't trust the list here. The terrain data is just too inaccurate and it doesn't take account of other transmitters on the same channel. Instead, use the Digital UK postcode checker.
This shows that Sutton Coldfield is your best option now and after switchover completes. If you want East Midlands news rather than West Midlands, you could also use Waltham.
There may be a basis for the order displayed, but I can't figure out what it is.
If analogue is snowy, your problem is probably a deterioration in the aerial or cable's performance. Check that the aerial is still pointing where it should be (299° for Sutton Coldfield) and is intact, and check for broken, loose or disconnected cables.
Predicted analogue signal levels are actually above the recommended *maximum* level for analogue with any aerial at all - using Field Strength Calculator I get a prediction of 84 dBuV for BBC Two (C40 at 1000 kW) using an aerial with 7dB of gain and 10m of cable. The recommended range is 60 to 80 dBuV, as it says at the bottom of the page.
However, according to their terrain information, there is a hill just to your north-west blocking direct line of sight, which reduces signals a fair bit. (RG47SH)

Mike Dimmick: Thank you for your response.
I thought this was the digital postcode checker....
....my main issue is with the signal keeps on disappearing (fine a couple of weeks ago, sporadic last week, completely lost over most of weekend (but ok Sunday mid morning), most of it back again today). I have just walked in from work and turned telly on.
Analogue:
Looks almost perfect on 1,2,3 and 5 (5 no picture glitches, but sound is crackling!), grainy on 4.
Digital:
BBC1 q=10 s=7
ITV1 q=4/5 s=6
ITV3* q=6 s=7
BBC Four* q=3/4 s=5
Pick TV q=0 s=5
Film4* q=4 s=4
* have all improved since lunch time! I swear I have touched nothing.

andy: I cant say it gets worse or better during rain as we have had none to speak of (very light smattering this morning).
Signal is still as it was when I got in from work (previous post). Is it just coincidence that Sutton had engineering works last week, and Sandy Heath turned up the power (almost directly behind me) and now I get a poor signal?

It does appear to be atmospheric related. This lunch time clear blue sky, quality on ALL channels 9/10, strength 5-7 across all channels.
The last week, that I have been experiencing problems has been mainly overcast.
Could this this be the "Inversion Effect", perhaps from the stronger Sandy Heath? What should I do about it?

Alan T: 'Normal' inversion problems (tropospheric enhancement, single bounce off the atmosphere) usually occur at night as the atmosphere cools. Tropospheric ducting (multiple bounces between layers in the atmosphere, travelling much further) requires specific weather conditions: you can see a forecast at Tropospheric Ducting Forecast for VHF & UHF Radio & TV . No ducting has been forecast over Rugby for the last week, though it was close on Saturday (see past week forecasts at the bottom of the page).
Sandy Heath has no channels in common with Sutton Coldfield at present. The commercial multiplexes' changes to their final channels and power levels are delayed, so while ArqA has been allocated C52, it won't get there until November, after Sutton Coldfield has stopped using it (and Tacolneston has stopped using it for C5 analogue). Likewise, Nottingham has been allocated that channel but won't get there until September.
I think it's much more likely that your problem is too much signal, and Mux B and C are clobbering each other, because they're on adjacent channels. An adjacent analogue channel seems to do much less harm, because most of the power is concentrated in the carrier sync pulses which have very narrow bandwidth.
How can it be too much signal with the box only showing 5/10 signal strength? Simply, that the meters are not calibrated to sensible levels. On my box 100% appears to be 95 dBuV, 35 dB greater than the maximum recommended level, or 56 times what it should be! 0% is 35 dBuV, about the minimum that could possibly work - at least an extra 10 dB is recommended to allow for normal signal variation.
I'd suggest removing any amplifiers you might have, and adding an attenuator if that doesn't help. (RG47SH)
