The symbol shows the location of the Black Hill (North Lanarkshire, Scotland) transmitter which serves 940,000 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 Black Hill (North Lanarkshire, Scotland) mast?

Tim: That booster? You probably don't need it.

Check that the box has actually tuned to Black Hill transmissions and not something else. The Kilmacolm relay transmitter is very close to you and uses lower frequencies, so could well be picked up when tuning, as older boxes often just store the first signal found when scanning. See Digital Region Overlap for thoughts on how to deal with reception from more than one transmitter.

Otherwise I'd be inclined to assume it's impulse interference caused by the thermostat or other central heating device (pump motor). Does it happen shortly after the central heating comes on?

If none of that sorts it, you can report the problem to the BBC at BBC - Reception problems . Select 'No' for 'Does this answer your problem?' and continue through.

Digital UK, and that BBC page, suggest that you can get a signal from the Strathyre Link transmitter, but I think that's very unlikely. It's probably what you'd expect to get from Black Hill if your aerial was pointing at Strathyre Link. My guess it's treated as a Single Frequency Network in the DUK predictor, but the sole purpose of Strathyre Link is to get the signal down the valley to the Strathyre transmitter itself, and hence is very, very low power (130 milliwatts).

Mike Dimmick: looking at the "Blue Book 7", it rather implies the change is just to increase the capacity of the multiplex from 24.13 Mbit/s to 27.14 Mbit/s


Option 1 - 2k (1705) 64QAM 2/3 1/32 24.1283422 Mbit/s

Option 8 - 8k (6817) 64QAM 3/4 1/32 27.1443850 Mbit/s

"For the Option 8 mode, transmission trials have started. It is too early to say whether the above modes under consideration will be specified for future use. It is felt prudent that performance parameters for Option 8 should be specified in this version of the D-Book. However at his time, receivers need only be tested ... with a small sub-set of the Option 8 performance parameters. "

Tim: I'm [still] suffering from the same experience on Mux2 Channels only. See my posting on the 2nd Oct. Although, in my case, the channels in question are JUST watchable. I have a Humax PVR and the signal detection shows the strength at around 60% and quality is constantly jumping between 40% and 80%. I know these readings through the PVR are only approximate, but the other Mux's show a higher strength signal and the quality reading is pretty well constant at around 80/90%.

I'm in Clydebank, not far to the north of you. I use Blackhill because Whitelees Wind Farm [currently the largest land wind farm in Europe] created similar, but worse, problems when the Darvel transmitter was used - although Darvel IS the Clydebank area recommended transmitter. In fact Scottish Power provide a free service for retuning to Blackhill - if required!

I'm wondering whether some minor wind farm, or something similar has gone up between us and Blackhill...?

I have been experiencing break up ITV around 6pm last evening, and a timer set for STV news went to 2 and a half hours!
Currently we have only BBC channels with 100% signal.
The signal on ITV came back briefly, without sound and breaking up! Then the screen displayed the NO VIDEO message!

Post I sent recently seems to have been lost, so here we go again.
Mike - we have a booster in the attic because there are about 5 TV sockets in the house and I thought it made sense to do the splits this way. However, as it turns out, there is usually only 1 TV turned on at any one time.
Mux2 signal strength drops below 30 and teh bit error rate climbs drastically when we lose signal - as you would expect. The other Muxs' are all sitting rock steady at between 70 and 75 signal strength with 0 BER. So there has got to be something either wrong with the transmitter or interfering with the Mux2 signal. If it was interference, I would expect another Mux nearest in frequency to Mux 2 to be affected as well (unless the interfering signal is very narrow band - which I would have expected if it was a washing machine or central heating pump - they would be fairly broadband). Mobile phone, OK, would agree, but are there mobile wavelenths operating around 650 MHz? If so, that would appear to be a "design" fault on someone's part. So, still a mystery. But thanks again for the replies.
