ILR COVENTRY (97.0 MHz v.h.f.- formerly 95.9 MHz v.h.f.) (Mercia Sound / Mercia FM):

Mercia Sound VHF map from 1980
IBA Map from the 1980 Handbook showing the predicted VHF contour for the 0.25 kW FM transmitter
at Shilton NGR: SP410836.  The original frequency in 1980 was 95.9 MHz.
The A.M. coverage is not shown on the above map, but covered a significantly wider area and was on
220 meters medium wave, 1359 KHz, with 0.17 kW e.m.r.p. - later increased to 0.27 kW e.m.r.p.

The v.h.f. coverage was later measured by the IBA, showing the actual coverage to be a little wider,
and this map is shown immediately below:

The general TSA (Total Survey Area) is shown by the radiating lines and is typically the
area where satisfactory medium wave (AM) reception is available during daylight

(Mercia Sound / Mercia FM etc)
VHF contours are for the 0.5kW transmitter at Shilton - measured coverage - 97.0 MHz (Now increased to  1.8 kW)
and the 0.05 kW relay at Leamington Spa

Map of the Shilton transmitter coverage area

The pixel plot above shows the coverage area from Shiton produced by the RadioMobile programme.
The Dark Green area is for the original 250 Watt e.r.p.
The Lighter Green area is for the 500 Watt e.r.p.
The Yellow area is for 1.8 kW e.r.p; which is the power being radiated in 2004 and is according to the directional
characteristics detailed in Ofcom's transmitter parameters.

ILR WOLVERHAMPTON (107.7 MHz v.h.f.)  (The Wolf)

Mander House coverage map
Pixel plot showing the expected coverage for ILR Wolverhampton 107.7 MHz v.h.f. f.m.
(107.7 The Wolf etc)
Transmitter is 0.17 kW at Mander House in the centre of Wolverhampton
Green area is the predicted 54 dB uV/m area where good reception should be possible
Yellow area is predicted 48 dB uV/m where reasonable reception may be possible with a
good radio and/or a good f.m. aerial.


Wolverhampton's very own Community Radio station, licence by Ofcom, launched on 30th March 2007.  As with most community radio stations broadcasting on f.m. (v.h.f.) the transmitter power is only 25 Watts (Vertically Polarised). WCR FM broadcasts on 101.8 MHz FM from a transmitter sited on the corner of the roof of the Adult Education College in Bilston Street, at the south east corner of the city centre. The broadcasts are in high quality Stereo and are encoded with RDS (Radio Data System) which displays the name of the station - WCR FM.

While the Bilston Street transmission site is quite high at 155 m above sea level (Wolverhampton city centre is on a hill overlooking surrounding districts), WCR's vertical transmitting aerial is only 20 meters above ground level, becuase the building is not especially tall, and its outlook is therefore somewhat blocked to the north and west by taller buildings. However the outlook is reasonably unobstructed to the east and south. Actual listening confirms that reception is quite poor in the western and northern parts of the city. I was pleasantly surprised to note that reception was just possible in the Edgbaston district of Birmingham on a good quality car radio, though extremely weak indeed, but reception continued and improved on a journey from Birmingham along the A4123 towards Wolverhampton.

Coverage map for WCR FM - Wolverhampton Community Radio

The map shown above is the predicted coverage produced by RadioMobile:

The Green (54 dB uV/m)
area is where reasonable reception should be possible even on a portable radio in some cases.

The Yellow (48 dB uV/m) area is where reception will probably be difficult, but may be possible given a good quality (i.e. sensitive and selective) radio and very careful positioning of the radio and aerial. It is always best to fully extend a telescopic/whip aerial and a position near a window may improve reception. - In this yellow area the use of a good quality hi-fi tuner connected to an external vertically polarised band 2 v.h.f. f.m. aerial (antenna) mounted above roof-top height should provide quite acceptable reception in mono.

The Blue (38 dB uV/m) area is where reception may be possible, but could be especially difficult. A good car radio may yield some acceptable reception and a hi-fi tuner connected to an external, vertically polarised band 2 v.h.f. f.m. aerial (antenna) mounted above roof-top height may also provide some reception. Portable radios will probably have to be of very good quality and have the aerial fully extended and carefully positioned and may not provide acceptable reception unless placed near a window and/or in an upstairs room facing the direction of Bilston Street.

Station Address WCR FM, Newhampton Centre, Newhampton Road East, Wolverhampton. WV1 4AP
Frequency 101.8 MHz V.H.F. / F.M. (Stereo)
Transmitter Location Bilston Street, Adult Education College, Wolverhampton
Transmitter Grid Reference SO917984
Transmitter Power 25 Watts e.r.p.
Aerial Polarisation Vertical
Transmitter Site Height 155 m a.o.d.
Transmitter Aerial Height 20 m a.o.d.
RDS code

For best reception the use a high quality stereo FM hi-fi tuner connected via high quality coaxial cable to a VHF / FM radio aerial mounted externally and above roof-top height (or at least in the loft space) is recommended.

For reception on a portable radio the use of good quality equipment is recommended - such as that from Panasonic, Sony, Roberts and Philips. The telescopic/whip aerial should be fully extended and carefully positioned until the best possible reception is obtained.

In difficult reception circumstances positioning the radio near a window may improve signal strength considerably. Siting the radio on the side of the house that faces Bilston Street may help. Reception in an upstairs room is usually stronger than in downstairs rooms.

In contrast to WCR FM, Wolverhampton's licenced ILR station on 107.7 MHz (The Wolf) benefits from an aerial mounted at  the top of Mander House, which is the city centre's tallest building and as such benefits from an unobstructed outlook in all directions. This is also a good deal more powerful at 170 Watts and benefits from mixed polarisation.

ILR BIRMINGHAM (102.2 MHz v.h.f.) (Galaxy)

Metropolitan House

Pixel plot showing the expected coverage for the ILR Birmingham (Galaxy 102.2  etc)
The transmitter is 1.0 kW and located on top of Metropolitan House, 1 Hagley Road, Five Ways, Birmingham
Red area is the predicted by RadioMobile to give reasonable stereo coverage
In 2004 a new Lindenblad mixed polarised transmitting aerial replaced the previous vertical dipole antennas, power increased from 500 watts vertical to 500 W V + 500 W H - totalling 1.0 kW mixed
