Qualifications: Meets applicable requirements of ICAO,FCC, and FAA. Frequency Range: 190-535 kHz, (optionally 190 to 625kHz) or (250 to 1250 kHz for offshore installation using the222 whip antenna), crystal controlled synthesizer, switchselectable in 500 Hz increments, stability better than .005% (-40°C to +70°C). Power Output: Carrier power into 50 ohms continuously adjustable 25 to 100 watts, (100-400 WPEP). Spurious Emission: Radiated harmonics (measured ata dummy antenna) are better than 63 dB below the 100 watt carrier. Type of Emission: NON, A2A, A3E (Optional), GID(with optional GPS beacon modulator, or any combination. Modulation: Switching modulator/regulator provides highlevel modulation 0-95 percent. Internal 400 Hz and 1020Hz tone is selectable. Internal keyer normally operates ateight baud (approximately 7 WPM) and is adjustable from 5 to 16 baud. In normal operation, carrier is on continuously with keyed tone modulation. Noise and Hum Level: Better than 40 dB below the carrier level. Input Power: 115/230V ±15%, single phase 50-60 Hz.24 VDC. Nominal input power is 180W at 100W carrier and tone keying at 95% modulation. Metering: Power output, reflected power, PA voltage,PA current, percent modulation, audio input level. Keyer: The solid state keyer provides 95 DIP switch programmable dot spaces. A dot space is adjustable from 63 to 166 ms. Special coding is available. Circuit Protection: Individual fuses are used to protect the AC and DC circuits. VSWR circuit that shuts down the transmitter if VSWR exceeds an adjustable value. Working Conditions: Continuous unattended operation in the following environments: ambient temperature, -50°C to +70°C; relative humidity, 0-100% noncondensing; high salinity as encountered in offshore conditions. Monitoring: Transmitter shuts down with loss of tone,drop in modulation below an adjustable value, or continuous tone, or when power falls below an adjustable value, or when VSWR rises above an adjustable value.With a dual system, a shutdown signal initiates a transferfrom the primary transmitter to the secondary transmitter.
