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?

I've been getting reliable HD reception on Ch59 from Blackhill at ML1 5NJ but since the day of the royal wedding the reception has degraded until today when there is no HD reception at all.
I have a wideband antenna pointed at Blackhill, and when I originally sited it the angle from which I got a signal was extremely acute. A nudge in either direction meant 0% signal for my Humax HD 2 box. So I am certain the antenna is sited and operating well.
Changing flyleads makes no difference either.
I've switched everything else off too to remove any potential interference sources.
SD channels are 75% strength and 100% quality BTW.
What should I do next? I want my HDTV!!!

I would be patient guys. By June the temporary transmission will have ended and HD will be transmitted at ten times the power (I know this is not the correct way to look at it - should be in decibels).
For what it's worth, I have never had a single problem with HD since I bought the TV and I live a long way from the transmitter.
I still hold to the theory that the propagation is directional and those at certain angles form the transmitter are having problems. No-one agrees with this though.

Scott: From what I have been told, all of the "preview" Freeview HD services have been "piggybacked" onto the analogue Channel 5 transmitter at the various sites, so they should have the same radiation patterns as the Channel 5 services.
These old analogue Channel 5 transmitters are all (I think) omnidirectional and not the "panel" type transmitters used for digital services which allow considerable flexibility for radiation patterns.

According to:
Black Hill Transmitter
Black Hill is planned to transmit a pre switchover low power HDTV MUX (on CH59 at 10kW) from Feb 2010. Its radiation pattern is the same as that for analogue C5, which is concentrated in a cross shape, due N, S, E and W, i.e. it is nominally omnidirectional.
My interpretation is that the signal is stronger on the east-west and the north-south axis, which would account for me getting perfect reception living due west and others having problems.
I accept I could have got this completely wrong but I thought this was worth pointing out.

jenny wilkie: It might be a good idea to do a "first time installation" on the BT Vision box.
