I read on a forum recently that Zodiac broadcasting who run The Radio Ship as a wi fi radio station, do not think that they are getting enough listeners, and may wind their operations up.
It is an excellent radio station on line, in my opinion. They play a good variety of oldies, linked together by archival clips of offshore announcements. It is very cleverly done. For example yesterday at 5pm I heard Andy Archer saying it was 5pm on Radio Caroline. On the weekend there are occasional shows with announcers. They have music hours dedicated to Radio 390, Britain Radio, King Radio and Radio Invicta. They have hours dedicated to the other offshore stations, with a good variety of clips from offshore radio. These archival clips do not repeat too often either.
