Incident at RED DEER REGIONAL AB (CYQF) (Conflict - loss of separation, Aircraft navigation/communication equipment)

UPDATE M. & M. confirmed that the transmit switch on C-GSFI was indeed the one sticking on intermittently. The defect was entered by the flight crew after they became aware of the problem. The defect was then rectified before the next flight.
While Edmonton ACC was vectoring two aircraft for spacing about 25 NM north of Red Deer, a third aircraft attempted to check in on the frequency, but his microphone was stuck open and for approximately one minute the Controller was unable to establish contact with any of his aircraft. Because of this interference, the two aircraft being vectored got to within 4 NM and 800 feet of each other. The required standard in this area is either 5 NM lateral or 1,000 feet vertical. The aircraft believed to be the one with the communication equipment problem is C-GSFI, a Cessna 425 enroute from Calgary to Edmonton.
