FM BROADCASTING TRANSMITTERS " MARK" It is intended for the broadcasting in FM band. The system transmits stereo and mono radio programs.Frequency synthesizer with digital indication allows the discrete tuning with a step 25kHz. Transmitters are produced in three modifications: "MARK-66"; "MARK-88"; "MARK-100". Specification | Frequency range: | | MARK - 66 | 65,8...74 MHz | | MARK - 88 | 88...100 MHz | | MARK - 100 | 100...108 MHz | | Nominal deviation: | | MARK - 66 | ± 50 kHz | | MARK - 88 | ± 75 kHz | | MARK - 100 | ± 75 kHz | | Output power onthe 50 Ohms load: | | MARK- XX/25 | 25 W | | MARK- XX/100 | 100 W | | MARK- XX/500 | 500 W | | MARK- XX/1000 | 1000 W | | Power consumption: | | MARK-XX/25 | 60 W | | MARK-XX/100 | 200 W | | MARK-XX/500 | 1000 W | | MARK-XX/1000 | 2000 W |
