Under Theodore Shackley's leadership from 1962 to 1965, JMWAVE grew to be the largest CIA station in the world outside of the organization's headquarters in Langley, Virginia, with 300 to 400 professional operatives and possibly including about 100 based in Cuba and an estimated 15,000 anti-Castro Cuban exiles on its payroll.
JMWAVE's activities were so widespread that they became an open secret amongst local Florida government and law enforcement agencies.
[2][3] On June 26, 1964, Look magazine published an exposé by David Wise and Thomas B. Ross which revealed that Zenith was a CIA front.
University of Miami authorities denied knowledge of the CIA operation, though Shackley claimed privately that University President Henry King Stanford was fully aware of it, and JMWAVE changed its main front company name from Zenith to Melmar Corporation.
[2] By 1968, JMWAVE became increasingly obsolete, and concerns emerged that the CIA station would become a public embarrassment to the University of Miami.
