It is not known why the owners of Radio Northsea International chose 1610 kHz, 186 metres, for the
medium wave outlet of their station. Whatever the reason, it was an unfortunate choice. Not only was it off the end of the
dial of some receivers but it caused intererence to the emergency services. The Dutch pilot service was forced to move its
transmissions from 187 to 182 metres and, in the UK, lighthouse communications had to boost their power because of the
interference being caused by RNI.
The station, which did not broadcast in Dutch at this time, was not particularly welcomed in Holland and, as British
listeners were complaining that RNI's signal was disappointing in the UK, the owners decided to move the ship closer. On
Sunday 22nd March, after just a month on the air, they announced that the Mebo II was to travel to Britain. This proved
to be another bad decision.

At 7pm the next day the anchor was raised and, broadcasting as she went, the ship circled the rival
Radio Veronica ship and set off for her new home.

The anchorage turned out to be six miles off the Clacton, Essex, coast and as soon as the Mebo
II arrived a deluge of complaints flooded in. RNI's medium wave frequency, 1610 kHz, was used by lighthouses,
lightships and coastguards and the station's signal was blotting out these essential transmissions. Because of the
interference it was causing, RNI closed down medium wave broadcasts on Good Friday 27th March. A few days later station
boss Edwin Bollier visited the headquarters of the Royal National Lifeboat Institute in London. He apologised for the
inconvenience that his station had caused and offered a large donation to the fund. This was refused because of concerns
that accepting it would contravene the Marine Offences Act.
THE JAMMING

On 10th April RNI was back, on a new frequency, 1578 kHz, 190 metres. Immediately the Post Office,
then responsible for policing the UK airwaves, announced that it had received protests from Norway and Italy, the two
official users of the frequency and, on 15th April, a Government-authorised jamming signal started to interfere with
RNI's AM output. Another wavelength change was announced, to 1385 kHz, 217 metres.
On 30th April the station re-opened on this new wavelength. Also the FM frequency was altered to 100 MHz. Unfortunately
a fault developed in one of the transmitters and a fire broke out on board. This was easily subdued but once again RNI was
silenced.
On 13th May it was back, this time on 1230 kHz, 244 metres, medium wave and 100 MHz FM. Both shortwave transmitters were
still out of action. Reception for this new medium wave frequency was excellent until 23rd May when the Post Office
resumed its jamming. A high-pitched tone was broadcast from a ten kilowatt transmitter located in a naval base near
Rochester, Kent. Although this made listening to the station extremely unpleasant, RNI continued. The jamming also caused
problems for people living near the naval base who were trying to listen to BBC Radio One (then on 247 metres, 1212
kHz).
