Scotland Glasgow Edinburgh Transmitter Coverage Area Maps

ILR GLASGOW FM1 - (Radio Clyde / Clyde One)

The IBA map for ILR Glasgow (Radio Clyde / Clyde One etc) - 102.5 MHz FM VHF contour is for the main transmitter at Black Hill - at this time the power was 3.6 kW and this has since been increased to 15 kW The coverage area will be marginally wider but not significantly different as the service area is determined more by the terrain of the locality.

ILR Glasgow (Radio Clyde) also has additional relay transmitters as follows:

Rothesay - 102.3 MHz - 0.6 kW
Roseneath - 103.3 - 0.1 kW
Milburn Muir (Vale Of Levan) - 97.0 MHz - 0.04 kW

The above pixel plot has been produced to show the approximate coverage from the major Glasgow ILR licence: Glasgow FM1 (Clyde 1 - 102.5 MHz) with the current transmitter power of 15kW maximum e.r.p. (10kW vertical + 5kW horizontal) from the main transmitter at Black Hill.

Please note that the above plot was produced without absolute reference to all the detailed OFCOM transmitter parameters - but it is sufficiently accurate to indicate the general area of reception for the station. A directional aerial pattern has been used to plot the map with the maximum power to the West which should be very accurate, the pattern used may overstate the reception in the East of the area slightly, but it should be nothing too significant.

ILR GLASGOW FM2 (Saga 105.2)

The above pixel plot has been produced to show the approximate coverage from the major Glasgow ILR licence: Glasgow FM2 (Saga - 105.2 MHz) with the current transmitter power of 30kW maximum e.r.p. (15kW vertical + 15kW horizontal).

Please note that the above plot was produced without absolute reference to all the detailed OFCOM transmitter parameters - but it is sufficiently accurate to indicate the general area of reception for the station. A directional aerial pattern has been used to plot the map with the maximum power to the West which should be very accurate, the pattern used may overstate the reception in the East of the area slightly, but it should be nothing too significant.

ILR EDINBURGH FM1 - RADIO FORTH

The IBA map for ILR Edinburgh (Radio Forth / Forth One etc) - 97.3 MHz FM VHF contour is for the main transmitter at Craigkelly - at this time the
power was 1 kW and this has since been increased to 9.8 kW The coverage area will be wider but not significantly different as the service area is determined more by the terrain of the locality

Forth One also has two additional relays: 0.1 kW on 97.6 MHz at Black Hill for Bathgate and a 0.25 kW transmitter at Penicuik
for Penicuik and the South Eastern reaches of Edinburgh on 102.2 MHz. The anticipated coverage area for the Penicuik relay is shown below:

ILR AYR WITH GIRVAN - WEST SOUND

IBA map for ILR Ayr with Girvan (West Sound / West FM etc) - 96.7 MHz FM VHF contour is for the main transmitter at Darvel - with an additional low power relay at Girvan on 97.5 MHz

ILR DUNDEE AND PERTH - RADIO TAY

IBA map showing the coverage area of ILR Dundee and Perth (Radio Tay / Tay FM etc) The Dundee 0.5 kW vhf transmitter (102.8 MHz) at Tay Bridge (shown here) has since been moved to Angus with the power increased to 5.25 kW. The vhf transmitter at Perth (96.4 MHz) has since had a power increase from 0.25 kW to 0.8 kW

From experience variable reception is possible across parts of Fife and over to Edinburgh and Dalkeith on 102.8 MHz

Predicted coverage plot for the Perth VHF site showing the combined 0.5 kW horizontally polarised directional signal
and the 0.3 kW vertically polarised directional signal: 0.8 kW maximium e.r.p. mixed polarisation.

ILR PERTH FM2 - Small Scale Radio Station "Perth FM 106.6"

The small scale second licence for Perth was advertised in 2006 and awarded to Perth FM. The original plan was to use the main VHF site at Kirkton Mailer using 1kW mixed polarisation and near omni-directional coverage. This would have provided excellent covereage on par with the BBC services from Kirkton Mailer and better than the VHF transmissions from the Perth TV site used by Radio Tay on 96.4 MHz.

However in the end Perth FM left it to the very last minute to launch (November 2008) and used a different site on the corner of South Street (A93) and Dundee Road (A85). This site is much lower down than either Perth VHF or Kirkton Mailer. The aerial height is also lower as is the power used - only 250 watts vertical. There is no horizontal component. The map above shows that coverage is greatly limited compared to Perth and Kirkton Mailer and may even (I feel) be somewhat of an over-optimistic prediction. The frequency used is 106.6 MHz VHF / FM

ILR FIFE - KINGDOM FM

Above: The anticipated coverage provided by the transmitters of the ILR station in the Kingdom of Fife - Kingdom FM. The transmitters are as follows:

1 - Purin Hill - 96.1 MHz - 0.5 kW
2 - Knock Hill - 95.2 MHz - 0.2 kW
3 - Allanhill Farm - 105.4 MHz - 0.1 kW
4 - East Neuk - 106.3 MHz - 0.15 kW
5 - Kirkcaldy - 96.6 MHz - 0.01 kW

(Variable reception is possible on 96.1 and 95.2 in Edinburgh and Dalkeith)

ILR STIRLING - CENTRAL FM

Above: The anticipated coverage for Central FM 103.1 from the 0.5 kW transmitter at Earls Hill. From experience variable reception is possible in Dunfermline and West Edinburgh and certainly over the Forth Road Bridge.
