COLINSWELL
- Medium Frequency Radio Transmitter - Serving
Edinburgh, Fife and East Central Scotland
Colinswell is the mast used by Edinburgh ILR radio station Forth
2.
Radio Forth opened in January 1975 simulcasting on 96.8 MHz v.h.f. / FM
from a 0.5 kW transmitter at Craigkelly and on 194 meters (1548 kHz)
medium wave / AM from a 2.0 kW transmitter located at Barns Farm.
The medium wave transmitter at Barns Farm had to be moved some years
later (late 1980's we think). We don't know why the site move was
necessary, but it may have been due to site redevelopment perhaps
(?). In any event the Independent Broadcasting Authority had to
find a new site for the AM transmitter, and this site at Colinswell was
chosen.
Update: Chris Ronald kindly adds this information: "Re your page on the
Radio Forth AM tx at Colinswell and the reason for relocation from
Barns Farm. In the early 1980’s a petrochemical development at
Mossmorran near Cowdenbeath was under construction (I was an apprentice
electrician at the time and worked on the 11Kv mains power
installation) and there was a pipeline laid the coast where a tanker
terminal was being built at Braefoot Bay. The Barns Farm
site was just up from the shoreline at Braefoot Bay so I’m
guessing that it was decided that to minimise risk it would be a
sensible idea not to have a 2.2kW so close to a petrochemical terminal."
I have heard the signals from this transmitter, and from Barns Farm,
very strongly in the evenings and mornings in the South West Midlands
over
many years and very clearly indeed too at times.
