Correspondence with Dr. Hansjoerg Biener in 2004:
Between 1974 and 1987 the RMC/TWR 1466/1467 kHz channel was used only from
Col de La Madonne French-near-Monte Carlo soil, from 1987 only at DAYTIME,
and from 1987 via Roumoules during NIGHTtime on a directional aerial five
mast system for both RMC and TWR purpose.
HJB: I don't think that the dates given are correct. The medium wave
station of RMC at Roumoules [in France] went on the air in September 1987.
This 10 Mio DM project was the first to be entirely financed by Radio
Monte Carlo itself. I agree with Wolfgang Bueschel that there were
daytime-nighttime shifts of transmitter use.
WB: acc to the web site RMC Roumoules-France tx site erected in 1974 as
longwave station 218, it was refurbished and re-inforced in 1983, by
replacement of the LW transmitters by more powerful Thomcast units, LW
218/216 2000 kW (2x1000 kW), and a 3rd 1000 kW unit in reserve.
LW consist two separate antenna systems, a 3-mast installation of 300
metres height each, directional pattern towards Central France, and a
single non- direction aerial, 330 metres tall. Switching procedure between
the installations last approx. 30 seconds.
WB: In 1987 at RMC Roumoules-France MW unit 1467 kHz of 1000 kW power was
built up especially for the TWR services towards Europe and the
Mediterranean area. The directional antenna construction consist five
masts of 100 metres height, produces powerful gain in five privileged
directions via ionospheric propagation during night hours. -
Targets / towards direction in degrs:
GB&IRL at 325 degrs
Scandinavia and NoEastEUR at 25 degrs
Eastern Europe and CIS states at 85 degrs
Spain, Portugal and NoWesternAfrica at 241 degrs
Italy, Albania and Greece at 150 degrs.
Switching time towards another direction is about in 5 seconds. Dead zone
of poor propagation of ground and sky wave mixture is about 100 kilometres
around Roumoules.
Roumoules: Les Ondes Moyennes.
En 1987 un emetteur ondes moyennes de 1000 kW a ete installe a Roumoules
specialement pour diffuser les programmes de Trans World Radio. Une
antenne directive dite a grand gain et composee de 5 pylones de 100 metres
de haut privilegie 5 directions d'emission en propagation ionospherique,
vers:
- la Grande Bretagne 325+,
- les pays scandinaves et le Nord Est de l'Europe 25+,
- l'Europe de l'Est et la C.I.E. 85+,
- l'Espagne, le Portugal et l'Afrique du Nord 241+,
- l'Italie et la Grece 150+,
