Caroline 98 was a weekend-only service which shared a frequency with Radio Zodiac, who ran from Mondays to Thursdays.
The dual service launched in June 1986. Radio Zodiac was a relaunch of a station which had stopped broadcasting in April 1985 and had merged with Castle K FM to become BFBS, also weekend-only.
When BFBS stopped broadcasting it reemerged as Caroline 98. At launch it had ambitious plans to have an all female line up. Unfortunately, this didn’t happen.
