The above QSL card was sent to us by Martin A Shelley who sent a reception report on 29th June 1964 from his home in Saundersfoot, South Wales.

 When the verification arrived (postmarked October 1964) the location of the MV Caroline had been amended, but clearly this was incorrect as the ship only arrived off the Isle of Man in early July 1964.

Martin had in fact been listening to the original Radio Caroline, anchored off Felixstowe, not Radio Caroline North from Ramsey Bay in the Isle of Man !

Thanks to Martin for allowing us to include this unique QSL card
