Black Hill Transmitter OS Grid Ref NS 828 647
Note As work takes place on various digital transmitters (to prepare for the DSO)
you may experience reception problems, e.g. with certain MUXES disappearing.
First try rescanning your set top box and if this fails to work check on Transmitter work
or phone reception advice on 08700 100 123 (BBC) or 0844 881 4150 (ITV).
Black Hill television transmitter was first opened in 1957 but the first mast was replaced by
a higher structure in 1961, the original was moved to Selkirk and is still in use.
It has the fifth highest population coverage of any TV transmitter at around 2.5 million and it is located 14 miles East of Glasgow. For the sake of impariality, that`s about 25 miles
West of Edinburgh ! The mast is 307m high giving a total aerial height of 543m.
The transmitter puts out all 5 analogue programmes at 500kW and Digital/Freeview MUXES at 20kW. Black Hill is horizontally polarised and was originally a B group but MUXES 5 & 6 now require an E group (or wideband) aerial. It should be noted that MUX5 is transmitted on CH55 and so will still be receivable with a B group antenna but MUX6 is up on 65 so will probably require a change of aerial unless you live in a strong reception area.
Black Hill is a main transmitter and it has fifty five smaller relays (or repeaters) to improve coverage in poor reception areas within its coverage area.

Also check Black Hill`s fifty five smaller relays
Note that Torosay, Darvel and Caldbeck transmit on the same frequencies. I suspect that Caldbeck may well have a restricted radiation pattern in a Northerly direction and that “Caldbeck Scotland” will act as a supplementary transmitter (on different frequencies) only transmitting in this direction, just like Winter Hill and Winter Hill B do now.
Angus and Rosneath also transmit using the same frequencies.
On the “Post DSO” guide (below), large gaps in the spectrum - for other uses - are present on channels 31 to 35, 37, 39 to 40 and 63 to 68.

Note the channels out of the original B group of the transmitter.
(see Channel Allocations Guides)
The graph below illustrates Black Hill`s channels in relation to B group aerials
which are
an alternative for those in particularly bad signal areas. A group B aerial will
work better
than an E group (or wideband) but will not pickup analogue MUX 6 until after DSO.
Post DSO all channels will be within the compass of our B group aerials.



For Black Hill`s TV frequencies/channels see its Channel Allocation Guides for before
and after the DSO. These also include the same information for other potentially
co-receivable transmitters within Black Hills coverage area, namely Craigkelly, Angus,
Torosay, Rosneath, Darvel, Caldbeck, Selkirk, and Chatton. This information can be
very useful for identifying possible causes of co-channel interference or other transmitters
which may give a superior signal. It can also be invaluable if you are trying to
find a spare channel for a modulated output (e.g. for a Sky box or CCTV system) to
be added to your TV setup/distribution system without suffering from co-channel.
Ofcom report that the transmitter has minor restrictions in power to the SE and the
NW on all six digital MUXES and DSO is due for March 2011. Unsurprisingly it has
been confirmed by Ofcom that Black Hill will be returning to a B group at DSO.
