designs. The remaining 5 kW transmitter was later converted for short wave use. The Ross Revenge also featured powerful generators. O'Rahilly wanted Radio Caroline to become an oldies station. He was opposed by some DJs and crew who had worked on the Mi Amigo and the album format stayed along with presenters such as Andy Archer, Samantha Dubois, Grant Benson, Robin Ross and Simon Barrett. Officially, Radio Caroline was managed from offices in North America, with advertising from the US and Canada. In practice, day-to-day servicing was carried from France and the UK. From the anchorage in the Knock Deep the Mi Amigos mast could be seen on the horizon. Four studios were on board, enabling other broadcasting services. Radio Caroline tried several frequencies, among them 963, 576, 585 (briefly), 558 (after Laser 558 closed) and later 819 kHz. European medium wave channels had been reallocated to multiples of nine. In the evenings on 963, some alternative music programmes were tried, including the reggae "Jamming 963", and in 1986 and early 1987, a progressive and indie rock programme called Caroline Overdrive hosted by Tom Anderson, Fergie McNeal, Andy Johnson, Stevie Lane, Mark Matthews, Kevin Turner, Peter Phillips, Mick Williams (a.k.a. Ray Clark) and Rob Charles. On 9 August 1985, an official vessel anchored 150 yards from the Ross Revenge. The UK Department of Trade and Industry (DTI) put a permanent watch on movements around the Ross Revenge and the MV Communicator, Laser 558s ship. On 3 September 1985 at 00:00 hours the Dioptric Surveyor departed in a storm. Radio Monique From December 1984 the Ross Revenge broadcast Radio Monique, recorded and live Dutch-language programmes of a Dutch music radio production company using the 50 kW transmitter during daytime. They were pop and Europop aimed at the mainstream Dutch audience. Radio Monique was popular throughout Benelux. In the evenings, Radio Caroline transmitted Dutch and American religious evangelist broadcasters such as Johan Maasbach and Roy Masters on medium wave, and later on short wave, under the name Viewpoint 963/819, or World Mission Radio (WMR) on short wave. In November 1985, the competing offshore station, Laser 558, closed after electrical problems and Caroline moved from 576 kHz to Laser's 558 kHz frequency, with a Top 40 music format similar to Laser's under the name Caroline 558. When Laser returned as Laser Hot Hits, it used Caroline's former and inferior frequency of 576 kHz.
