Radio Caroline made a surprise, albeit brief
return in June 1970.
Radio Northsea International had started
broadcasting, from off the Dutch coast at the start of 1970, and a few
months later had moved across to a position off the English coast.
The move did not please the British government,
who thought they'd seen the last of offshore radio, when Caroline had gone
off the air in March 1968. The government considered a number of ways to
get rid of this new offshore station, including forcibly boarding the ship
and taking it off the air. Eventually they decided to jam the stations
signal, which it was claimed was being done at the request of Czechoslovakia.
Radio Northsea - RNI moved frequency a number of
times to avoid the jamming signal, and also stated that they had
permission from Czechoslovakia to use the 244 Metres / 1230 Khz frequency.
