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?

steve: If signals are bad on C55, C59 and C65 but good on the others, the most likely explanation is that you have a Group B aerial, covering only channels 35-53, rather than a wideband. A Group E semi-wideband, covering channels 35-68 is recommended before switchover.
The HD service will be worse affected than Mux C and D because it's half the power, and requires more than twice as much power as those multiplexes do. (This page shows this for Mux 2 and A, which also use a mode requiring more power than Mux 1, B, C and D, but not for the HD mux.)
However, at switchover, all services move into Group B, so I wouldn't bother for just two more months (plus two weeks - only BBC SD services move on the first day, HD services don't move until 22 June).

Have a problem receiving HD mux from blackhill which has me confounded. It should be on channel 59. Am based in Edinburgh.
Am using a new Sony HD Freeview+ receiver which tunes all the SD muxes no problem.
Receiving the Mux's on ch55 and 65 no problem, so I guess aerial is ok.
What mode is this mux running? Is there something I can check?

I still cant get any of the HD channels and my aerial is pointing at the Blackhill transmitter although I am a good bit away in Grangemouth. Any ideas? I also noticed that there is a Grangemouth transmitter

Graeme: You are predicted to be able to receive Freeview HD, as long as you have a suitable receiver. Grangemouth digital switchover date | ukfree.tv - independent free digital TV advice will not have Freeview HD until Wednesday, 15th June 2011.

Many thanks for the tips Briantist.
Sadly no luck so far. Have turned off virtually else off in the house, including the fish tank pump and disconnected all switch mode power supplies and chargers etc .
I also tried looking at the analog background on ch59'by using the fine tuning on my telly's analog tuner. No signal or evidence of background noise.
The really odd thing is that despite getting very good quality and 80% levels on ch55 and 65, there is NO signal on 59- zero, nada, none.
It seems to be a recurring theme on this thread for Blackhill. saw somewhere that the transmitter for this mux maybe halfway up the mast. Can anyone verify this?

According to
mb21 - The Transmission Gallery
The site transmits all 5 terrestrial television channels, with Channel 5 analogue operating at the same power as the other channels (500kW max ERP), from an aerial only marginally lower.
Briantist has said earlier that the HD multiplex is transmitted from the same aerial (antenna for those who prefer American).
Make what you wish of the comment on
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.

Thanks again Brian
The receiver is the new Sony svr-hdt-500 hd freeview box. Definitely supposed to be hd but i agree that the symptoms point to a sd tuner!
I have tried factory reset etc. Thus far there appear no updates on the Sony site for firmware.
Scott- thanks also for your comments. I guess this means there should be no directional or elevation issues with receiving the hd mux.
Perhaps time to return the receiver?
