CBS’ 103.3 WEEI-FM in Boston was in the process of a drawn out evolution from Soft Rock to Top 40 in the early 1980’s. The station had already been using the name “Hit Radio 103” when CBS sold AM sister 590 WEEI. As part of the sale, per FCC rules at the time, 103.3 had to change it call letters. In order to play up the new “Hit Radio” format, WHTT was born. This aircheck features a WEEI-FM legal ID from 5:00pm on March 8 and the birth of WHTT at midnight on March 9.
