McMaster Students Union had its application for an FM station denied. The 107.9 MHz frequency applied for was awarded to Burlington Broadcasting Inc. The CRTC was impressed by the McMaster proposal but was unwilling to assign a class B channel for a low power, specialized station.
McMaster Students Union Inc. tried for an FM licence again. This time they were successful. A licence was issued for operation on a frequency of 93.3 MHz with an effective radiated power of 50 watts.
McMaster University's CFMU signed on the air on January 13. The station had broadcast before this as an AM closed-circuit operation. The "MU" in the call letters: McMaster University. CFMU used a Wilkinson transmitter and 2-bay circularly polarized Phelps Dodge antenna.
Alex Daschko, on behalf of a company to be incorporated, received approval to acquire CFMU-FM from the McMaster Students Union Inc.
On January 11, the CRTC renewed CFMU's licence until September 30, 1985.
On November 1, CFMU received approval for the relocation of its transmitter from the urban core to the escarpment overlooking Hamilton (McMaster Chedoke Hospital).
On January 29, the CRTC approved the application to amend the licence for CFMU-FM by increasing the effective radiated power from 50 watts to 250 watts. The Commission noted that the increase in power was associated with a decrease in the antenna height. The licensee indicated that these changes would result in a slight increase of the station's coverage area and improve service.
CFMU was searching for a new transmitter site. The signal from the existing tower atop Chedoke Hospital was not penetrating the east end of Hamilton. There were also concerns about the future of the hospital due to restructuring of the health care system.
On June 9, a decrease in effective radiated power from 250 to 166 watts was approved. CFMU also proposed to relocate its transmitter a distance of 2.5 kilometres to the existing CIOI-FM site at Mohawk College. A directional antenna would be used.
CFMU began broadcasting from new studios in the basement of the student union centre.
On August 13 the CRTC renewed CFMU-FM's licence until August 31, 2014.
