Notes:

1 According to an advertisement in March 1, 1948 Broadcasting  magazine,  WJHP-FM was the first FM station on the air in Jacksonville. The ad states that WJHP-FM is now on the air eleven hours daily!

2 WJAX-FM appears to have been the second FM signal in town based on dates of FCC actions on construction permits. Possibly WMBR-FM didn't make it on until early 1950. 

3 Became WZFM in 1960.  Reverted to WZOK-FM in 1961.  Left the air in 1962.  Reactivated as WRLJ in 1968 by Belk Broadcasting.  Call changed to WPDQ-FM in 1969.

In early 1973, WPDQ AM's contemporary music programming shifted to FM.  WPDQ-FM aired an automated service entitled Solid Gold.  Despite the title, Solid Gold was a mixture of contemporary hits and oldies, some quite obscure.  Nightime hours were devoted to progressive music. WPDQ-FM became WAIV in 1976.

4  Before becoming Jones College Radio, WKTZ (96.1) was co-located in Atlantic Beach with WKTX (AM).  Jones College Radio drew a significant listenership programming semi-automated low-key music.

5 A milestone occurred in 1965 when low-key music station WALZ became WQIK-FM and started operation as Jacksonville's first fulltime country music (C&W) station. WQIK AM was daytime-only.

6 In 1971, WIVY-FM became the first FM station to program contemporary and progressive rock music fulltime.  WIVY AM/FM gradually shifted to a top 40 format.  By mid 1974, it topped WAPE AM according to some audience measurement ratings.  

7 After WKTZ moved to Jones College, WAQB-FM began transmitting from the same WKTX (AM) Atlantic Beach location near the ICW on Atlantic Blvd.  By 1970, WKTX (AM) and WAQB-FM became WJNJ AM/FM. WJNJ=Jack & Jerry, two of the owners.)

Additional Notes:

Dates cited in references vary and should be considered as being plus or minus at least a year.

Before the mid-1960s, FM stations often were off the air or inactive for extended periods.  FM listenership was small. Broadcasters kept stations active only to meet FCC license requirements hoping to profit in future years.

Most FM stations simulcasted programming from AM counterparts.

Some didn't sign on until 5pm or so.  

Some stations had interim callsigns that are not indicated above.

By the mid 1970s, cheaper FM receivers, better technology, the addition of FM capability to car radios and FCC restrictions against duplicating AM station programming led to greatly increased audience potential and profitability for FM broadcasters.

* = Exact sign-on years/dates and effective radiated power (ERP) levels for early FM stations varied among references books.  

Dates listed are those deemed most credible.

With power levels, who knows?

Generally, individual station ERP levels increased over the years up to 100kW maximum in some cases.

By 1970, the term megacycle (mc.) had been replaced by megahertz (MHz) in common usage.
