No Signal from Black Hill transmitter C43 & C44 for coverage in EH11 Edinburgh. Although Engineering work is necessary, doing it on a weekend is very annoying. Hope it's back to full service soon.

I'am missing various channels on my communal aerial. Is it the Council that looks after this. Some of the houses in my area are bought and some are rented from council?

It seems to be com7 that I'am missing channels from. Any ideas. The signal strength I get from the communal aerial is 100%.

GMAN73:
100% signal strength is far too high! At that level most HD capable TV sets or set top boxes with claim there is no signal as it's so strong it 'swamps' the tuner system. The idea is more like 50% to 70% for SD and HD services.
COM7 is an HD multiplex so with signals that strong you are very unlikely to get any of the channels on that multiplex. Search on this website for "too much of a good thing" and see what is generally accepted as good advice, namely reduce the signal strength with an attenuator.
A full piost code would allow us contributors to determine your reception conditions and perhaps give more advice.

Thanks MikeP,
Is the attenuator the same thing that Virgin Media put on your Superhub to reduce the Power Levels. I have a spare 4db attenuator or will I need a larger number.
My Post code is G14 0YE, I fall under the Blackhill Transmitter for Central Scotland.
I have checked my TV and this is the levels Im getting for some of the channels I checked.
BBC 1 Scot (001) - Signal Quality - 100% / Signal Level - 80%
BBC 2 Scot (002) - Signal Quality - 100% / Signal Level - 80%
STV (003) - Signal Quality - 100% / Signal Level - 80%
BBC 1 HD (101) - Signal Quality - 100% / Signal Level - 76%
BBC 2 HD (102) - Signal Quality - 100% / Signal Level - 76%
Sky News (132) - Signal Quality - 100% / Signal Level - 72%
E4 (28) - Signal Quality - 100% / Signal Level - 80%
BBC News SD (132) - Signal Quality - 100% / Signal Level - 79%
In my back garden there is a manhole cover, which has coaxil cable in it, think this might be the cable coming from the Communal Aerial.
Thanks very much.

GMAN73: These levels are perfectly OK, the advice given by MikeP was based on you having said that signal *strength* was 100%.
The signal path from Blackhill is seen to be obstructed at approximately 0.75 miles prior to your location, and this might be a contributory factor in not receiving any signal the COM7 transmitter, as no engineering work is being carried out at Blackhill, nor are any faults listed against it.
You should try carrying out a "manual" tune on C32/562.0Mhz (Blackhills COM7) pausing after entering the channel number, (do *not* press search) to see if any levels appear on the signal bars, if they do, try pressing search and check if they get entered in the EPG listings, e.g: 107 BBC News HD.
