My postcode is G67 4SE.
Recently my reception on Mux channel 41 has been impossible to watch due to low signal strength/interference. At present time of 1225 16MAY2015 the picture and sound are perfect. I am watching my channel10 (ITV3) and the system indicates full signal strength. When the picture and sound breakup on the channels on this MUX I can tune to STV Glasgow and the picture and sound are perfect. I understand from your website that this is from a low power transmitter, so I don't think the problem relates to my aerial. My aerial is roof top mounted and was installed by a professional company.
Please let me know what you think is going wrong.

Hi. I'm in postcode ML5 and I've noticed significant issues with am radio frequency interference across all my devices, including car radio (used in ml5 and ml6 areas). Specifically, talk sport, 5live and BBC Scotland.
Do you know if there are understood issues?

Alexei Romanov: You havn't given your full postcode, so I dont know your location in relation to the transmitter. However, a decent bet is that your aerial has a problem, perhaps a frayed cable, etc. Check your signal strength (obviously make sure your tuned to the transmitter your meant to be) - and then check your system. It might be something as simple as a loose or broken aerial lead from the back of the set.

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.
