A Gallup poll published in April 1964, after the station had been on the air for just one month, revealed that out of a potential audience of 20 million listeners aged 17 and above an estimated 7 million had tuned to Radio Caroline's broadcasts at one time or another. The immediate and overwhelming popularity of Radio Caroline programmes demonstrated the public demand which existed at that time for an all-
By the end of April 1964 advertisers, realising the huge size of Radio Caroline's audience and the apparent absence of any official action against the station were beginning to lose their initial inhibitions about buying airtime.
The very first commercial on the station, aired on 1st May 1964, was for Woburn Abbey, a stately home opened to the public by its owner, the Duke of Bedford. Increased attendances were reported by the Duke in the days immediately after transmission of this commercial and soon afterwards other advertisers also began booking airtime. Amongst early Radio Caroline advertisers were national clients such as Harp Larger, News of the World, William Hill's Turf Accountants, Ecko Radios, Bulgarian Holidays, Peter Evans Eating Houses and Kraft Dairylea Cheese.
In a written statement to the House of Commons on 12th May 1964 the Postmaster General, Reginald Bevins, indicated that, although Radio Caroline had allegedly been responsible for interference to British and Belgian maritime communications during its first few days on the air, interference since then had been negligible and, for the time being at least, the Government had put off taking any unilateral action against offshore broadcasters pending the formulation of a concerted approach by all European countries
Meanwhile Allan Crawford’s rival station, Radio Atlanta, began test transmissions on 9th May 1964 with regular programmes starting on 12th May 1964 on a frequency a mere whisker away from Radio Caroline's. With the history of close links between Radio Caroline and Radio Atlanta since their inception and the fact that they were both targeting the same audience in the south and east of England it is not surprising that by early June 1964 rumours began to circulate about a merger between the two rivals. After more than a month of negotiations the directors of both stations agreed to a formal merger and a joint press release was issued on 2nd July 1964.
Without any ceremony Radio Atlanta ceased broadcasting from the Mi Amigo at 8.00pm that evening (2nd July 1964) and, after Radio Caroline had also closed for the day, the MV Caroline sailed to within a mile of the former Atlanta vessel, Mi Amigo.
Arrangements were then made to enable Radio Caroline to commence transmissions at 6.00am the next morning as scheduled, not from the MV Caroline as it had since the end of March, but from the former Radio Atlanta ship, Mi Amigo. The intention was that it should not have been obvious to Radio Caroline's listeners that overnight the station had completely transferred operations to what had formerly been a rival radio ship.
Because Radio Atlanta's programmes were mostly taped on land the Mi Amigo had few on-
With essential wiring work not completed until about 5.40am, Radio Caroline South only just made it on air as scheduled at 6.00am on 3rd July 1964.
