Really? 7-7 was eliminated in ’84?
Yes, and prior to 1996 we also had duopoly building. For example, Heftel owned 3 FMs and two AMs in the Dallas market prior to 1996. A number of companies either increased their station count in existing markets or added markets. These included Jacor, Clear Channel, Cox and a number of others in smaller markets, like Ingstead.
Cox, for example, had 3 FMs and an AM in LA in 1994, about two years prior to the more extreme 1996 change.
Back to Jacor. From a brief history of that company: " In 1984 Congress eased the radio ownership regulations somewhat and established the "rule of twelves." Under the new regulations, a radio company could now own up to 12 AM and 12 FM stations across the country. That year Jacobs began to seriously expand the company, acquiring WQIK-AM/FM, two stations in Jacksonville, Florida, for $5 million.
1985-89: Continued Growth
The Florida purchases were followed in 1985 with the acquisition of two stations in Cleveland, Ohio, for $12.8 million, and a move into the Georgia market with two stations and the Georgia Radio News Service for $20 million. In 1986 Jacobs purchased an FM station in Cincinnati for $9.3 million, and in December Jacobs merged Jacor with another Cincinnati radio company, Republic Broadcasting Corp. As a result of that transaction, Republic's head, Randy Michaels, joined the Jacor board.
The company continued to grow through acquisitions. In 1987 Jacor paid $24 million for two stations in Denver and in 1988 increased the company's presence in Florida by purchasing Eastman Radio, Inc. and two stations in Tampa, spending approximately $28.5 million."
Obviously, Jacor was well on its way to 12/12 soon after the rules changed. Read more on this one at

PS - I am a bit surprised that no one has jumped in to support you by saying that their company owned 8FMs right after ’84. . . but hey, don’t let that bother you. . . you can always ask your buddy who claims to have been in a big market (likely while on vacation).
I think if you get a 1986 Broadcasting Yearbook (which would show the status towards the end of 1985), you will find the beginning of the expansion beyond 7/7 in radio... with multiple operators starting to increase towards the new caps... and then agressively growing when in-market caps were increased.
