 Frequency Finder UK - Radio 1 transmission history
Prior to launch additional Radio 1 transmitters were built for the Midlands; South Wales, Avon & Somerset; Southampton & Portsmouth; the Brighton area; the Norwich area; and Hull, all on 1214 kHz, or 247 metres as radios were calibrated in wavelengths on AM then.
The transmitters serving the North, Midlands and South East were tripled in power and new high power transmitters introduced for the South West and the North East.
Four transmitters were then ceremonially switched on through the day: Wrotham for the South East (replacing Crystal Palace), Tacolneston for Norfolk and Suffolk, Sandale for North East Cumbria and South West Scotland and Blaenplywf for Ceredigion and SW Gwynedd.

 LF Radio Data
These transmitter sites are located at Burghead (50 kW) north Scotland, Westerglen (50 kW) in south Scotland, with the main transmitter located at Droitwich in central England (500 kW).
The stability of the long wave transmitter carrier is very accurate and can be used as a frequency reference.
The audio is used to amplitude modulate (AM) the carrier wave, whereas the data signal is transmitted by phase modulation of the carrier wave.

 Ross Revenge - Transmitter Room - Continental Electronics   (Site not responding. Last check: 2007-10-23)
These transmitters were available as both medium wave and shortwave variants, with very little difference in circuitry, and many hundreds, if not thousands have been built and shipped around the world since the 1960's.
I am unsure as to the exact release date of the 315/316/317B, but a good guesstimate would be 1957, a year after RCA launched the first ampliphase the 50G.
An even later version of the 316, the 316F is generally regarded as being the finest sounding AM transmitter ever built, with exceptionally low distortion and noise levels and excellent phase characteristics.

 Frequency Finder UK - History of radio transmission
A smaller 5 kW transmitter was opened at Penmon to bring the Welsh Regional Programme to North Wales and Aberdeen was replaced by a 5 kW transmitter at Redmoss.
To combat this, the long wave transmitter was closed and the medium wave transmitters grouped into three synchronous groups of four on the same frequency.
Increasing the bandwidth on AM was not an option because of interference to and from foreign stations.

 Radio Rewind - Radio 1 History - Transmitters
The transmission wavelength of Radio One was moved from 247m (1214 kHz) to 275 and 285m (1053 and 1089KHz) in November 1978 as part of a plan for BBC AM broadcasting in order to improve national AM reception, and to conform with the 1975 Geneva Conference on radio wavelengths.
The use of two AM frequencies avoided the problem of interference due to nearby transmitters operating on an identical frequency.
Radio 1 lost its AM 1053/1089KHz (275/285m) frequencies at 9AM on the 1st July 1994 due to a Government Bill to encourage commercial radio competition on AM.

 List of masts - Article from FactBug.org - the fast Wikipedia mirror site
Electric devices on them are fed via cables running through the coils of a parallel resonance circuit which is switched in parallel to the transmitter output.
For high power transmitters in the MW range, masts with lengths around half of the radiated wavelength are preferred because they focus the radiated power better to the ground than constructions with heights of quarter wavelengths, which are preferred of economical reasons for low power medium wave transmitters.
For longwave transmitters, however, the construction of masts with heights of half-wave wavelength is, because of economical reasons (and perhaps problems with the flight safety), in most cases impossible.

Yes they are 'daft' suggestions because none of those transmitters cover more than about a quarter of the UK during daytime and away from the coasts you are talking anorak quality not fussy listener standard.
Any broadcaster wishing to use an overseas transmitter to broadcast to the UK can only have the coverage that is provided by that transmitter and not hope to cover the whole of the UK with it.
So, the idea of broadcasting on AM from foreign shores may not be ideal, but it is better than nothing in the absence of any other alternative that has reasonable coverage and can be received on portable equipment that the listener already owns.

 Aircheck UK
There are 43 transmitters serving the British Isles - between 99.9 and 101.9 - six dotted around the coast of Wales, two in Northern Ireland, six in Scotland, one on the Isle Of Man, one on the Isle of Wight, and the remaining 27 across England.
The 1970s saw the island's ministers making repeated requests for increases in transmitter power, but they were told that this could not be possible due to the fact that, with the newly established commercial mainland operators, such an increase could steal listeners away.
This was due to the BBC's equivalent of the old IBA and subsequently RA's policy of not simulcasting on two frequencies and to encourage commercial radio on the AM band.

 Droitwich AM transmitter
The Droitwich AM transmitter is a large broadcasting facility for longwave and mediumwave established in 1934 close to the village of Wychbold, near Droitwich, Worcestershire, England (Grid reference SO929663).
This transmission site is the location of the strongest longwave transmitter of the British Broadcasting Corporation, which together with the longwave transmitters at Burghead and Westerglen forms a network on the same frequency.
The carrier frequency is controlled by an atomic frequency standard in transmitter building, enabling the transmission to be used as an off-air frequency standard.

 UK Radio History 1, Marconi, 2LO, BBC and Radio Normandy By Mike Smith
On 17th February 1935 the BBC moved Midlands regional transmitter from Daventry to Droitwich to form the Midlands 'twin-wave' station, on the same day BBC Belfast was renamed BBC Northern Ireland and changed wavelength from 267 to 307 meters, with improved reception.
The 150kW Droitwich longwave transmitter was also converted to medium wave operation and together with the other former National Programme transmitters, was synchronised on 1149kHz and broadcast the European Service during the hours of darkness.
Subsequently the 5XX transmitter at Daventry, the Droitwich transmitter and a new transmitter installed at Brookmans Park were established as a longwave group of transmitters to broadcast the European Service on 200kHz, later joined by a high power transmitter at Ottringham in the East Yorkshire Riding, in February 1943, also using 200kHz.

In Europe, North Africa and Asia, longwave radio frequencies in the band 148.5 to 283.5 kHz are used for domestic and international broadcasting.
In the Americas, frequencies between 200 and 430 kHz are used for non-directional beacons (NDBs), and do not necessarily follow the same 9 kHz spacing that other areas do.

But also using 909 is a 1 kW transmitter at Whitehaven (west Cumbria), Lisnagarvey 10 kW (N. Ireland) and Westerglen 50 kW (Central Scotland) and so even using a portable receiver with ferrite rod antenna it is necessary at my coastal location to position the receiver carefully.
Sounds like a transmitter is off frequency he told me. Imagine my surprise when I received yet another call later on from an engineer who had been sent to the Lisnagarvey site and he had called to ask what my reception was like now after making some adjustments.
I am still mystified but maybe worth passing to the Digest to see whether a monitor further East has noticed a broadcaster filling the gap between 1200 (end of Radio Australia) and 1600 (start of VOA Africa).
