Narrative:
Due to a stuck microphone from a company a aircraft a possible loss of separation occurred between company B jet and company a jet. The microphone was stuck for approximately 5-6 mins. In this time I was unable to communication with a total of 8 aircraft on my frequency. In these cases I should be able to override the stuck microphone and communicate with all aircraft except the stuck microphone. I couldnþt and didnþt know why.
