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?

Alexei Romanov: Becuase you put your postcode into thsite, we can see all the data for terrain, etc. You should be getting a very good signal from Black Hill, so if its duff, that points to a problem with the aerial system. Although BBC tends to be the strongest signal, if there is a break, etc, it could be that they disappear first (sound strange, but there you are).

Alexei Romanov: Can't speak as far as last weeks problems are concerned, but please be aware that as from today (3/8/2015) engineering work is taking place at the Blackhill transmitter, a notice to this effect of "possible weak signal" having been posted on the engineering page.

Thanks Mike,it must be the engineering work,I have checked my tuning and have 83 channels of which 50 areTV.For years I have had no trouble,it is just in recent months sometimes a few of the BBC channels and HD just goes completely.My set just gives signal quality which can fluctuate widely.

Alexei Romanov: I'd still check the connectons etc. When a signal is coming and going, people often seem to write it off as 'engineering work' (which it cant be - you said you've had signal problems for three months) or ''atmospherics' (which is unlikely for several months!). On the other hand, a failing booster, corroding wiring or a split in the cable sheathing which lets in water are all problems that can get a bit better for a while, but will fail in the end.

MikeB: If it were the problems you highlight how come I get perfect signals for 40 TV stations.It's the UHF channel that transmits BBC channels that has gone.

Alexei Romanov: Because life is strange. Your missing a single mux, which is normally amoungst the most powerful - in fact its 100,000W. However, if you have a look back at past questions, it has sometimes been the case that a stronger mux has vanished, whilst 'weaker' ones have remained. The problem has normally been a frayed cable. Remember that whilst you might think that the other channels are 'perfect', checking the signal strength might show that they are just about OK, but the BBC mux is below the level where you get a signal at all.
It might be nothing to do with that at all, but what else could it be?

Alexei Romanov: Irrespective of any other factors which may, or may not be involved, the fact remains that the "possible weak signal" notice which has been in force since a week last Monday, applies to the multiplex you are having problems receiving.

Mike B: Absolutely correct. I had a reception problem in June with on of c44 Mux and replacing a 3M coax internal extension cable solved my problem. Cable cost under £5. Time to change the cable over and dispose of the old one 10 minutes. I use the Blackhill Transmission Service.

Why is the transmission on Blackhill C32 (562.0MHz) so weak? All other frequencies show 100% signal strength and quality but C32 signal strength is less than 30% making Freeview HD channels on this frequency unwatchable. Are there plans to increase the signal strength of C32 and if not, what is the solution?
