Abstract :
During 1991 a number of inductive output tube (IOT) equipped transmitters were installed by Comark. Equipment using the IOT in both diplexed and common amplification applications are now in service at power levels from 30 kW to 120 kW. The author describes the unique features of the IOT transmitter and details several installations from both a physical and operations point of view. Finally, the author describes a new UHF transmitter breakthrough that provides 110 kW peak visual output and 11 kW average aural output from only two parallel 60 kW EEV #IOT7360 IOT tubes in common amplification
