Wavelengths/Frequencies
RNI was unique in broadcasting on multi frequencies using AM, FM and shortwave. However due to complaints of interference and government jamming signals frequent changes of wavelength and frequency had to be made.
6210kHz (49m short wave band) and 102mHz FM
(tests from 23rd January 1970)
186m (1610kHz) medium wave (AM)
(tests from 11th February 1970)
102mHz FM and 190m (1578kHz)medium wave (AM)
(from 10th April 1970)
217m (1385kHz) medium wave (AM)
(from 30th April – 1st May 1970)
100mHz FM (from 30th April 1970)
244m (1230kHz) medium wave (AM)
(from 13th May 1970)
Various medium wave (AM) frequencies between 1227kHz and 1232kHz (changing frequency every 15 or 20 minutes from 28th May 1970 to avoid British government jamming signal)
217m (1385kHz) medium wave (AM)(from 28th June 1970) but the jamming followed and the station reverted to 244m (1230kHz) medium wave (AM) (from 30th June 1970)
102mHz FM (from 24th June 1970)
6205kHz in the 49m shortwave band and 217m (1385kHz) medium wave (AM)
(from 3rd August 1970)

9940kHz in the 31m shortwave band

Broadcasting Hours
RNI’s broadcasting hours varied enormously during the lifetime of the station.
With the introduction of Dutch language programmes in 1971 these generally occupied the daytime hours, while the English language service was provided overnight.
The World Service varied too - sometimes it was broadcast daily and other times just at the weekends, often only Sundays.
