Peter McDonald was the third junior technician appointed by the TV station. Peter was also one of the junior technicians involved in the three week cycle of one week transmitter shifts and two weeks studio shifts. He worked mainly with Gordon Snell on the rotating shifts.
However, he moved across to the operational side of the station sometime later. He became a program switcher, assisting Keith Paton who had also moved from the technical staff to become a program director. Peter also assisted in other areas of the production side, and other work on the operational side of the TV station.
