Aeronautical and Maritime Radiocommunication Systems T The EMRY991N unit is a VHF ground transceiver derived from the T TELERAD 900 series technology which already proved its utmost w reliability.  O OVERVIEW E Especially designed for voice communication in control t towers, control shelters or ships, the EMRY991N can be u used for the Navy communications (Navy Mobile Service c channels*) in frequency modulation. T The channel spacing and associated bandwidth p parameters are automatically determined by the displayed f frequency value, in accordance with annex 10 of the ICAO recommendations. r For transmission, the operator can, at any time, select one of F two output levels : nominal power or reduced power. t There are 99 channels available to users with frequencies, T power levels (normal or reduced) and with squelch initiation p levels that can be programmable individually. l Principally designed to be operated by a controller from a P front panel which includes all the required elements and f required ergonomics, the set is also equipped with all the r means of access required for remote operation and a remote m control/supervision serial link. c The control human/machine interface consists of a keyboard T and a display unit with four lines of 20 characters each, all a operated in “menus” mode. o The rear panel has separate RF connectors for transmitter T and receiver section, and also a location for a coaxial relay, a allowing the use of one common T/R antenna, or separate T a and R antennas according the installation. a The transceiver, is 19" wide and 3U high, and can be supplied T in rack mounting or desk version. i  GENERAL CHARACTERISTICS Frequency range: 118-144 MHz in A3E mode 118-163 MHz in F3E and G3E modes Other frequency range in option Channel spacing: 25 kHz (12.5 kHz), 8.33 kHz automatic selection according to the frequency coding (ICAO annex 10) in A3E mode Preset channels: 99 preset channels with frequency, offset frequency, bandwith, power level, squelch threshold level parameters Frequency accuracy: 1 ppm Remote control:  By series link RS485, under JBUS protocol  3 wires parallel access (channels 1 to 8) Radio squelch: locking of a loop to the ground to forbid transmission Power supply (all versions): DC: 21-31 VDC (rated 24 V) Power supply EMRY991NxA: AC: 85-265 VAC, 47-63 Hz Mechanical characteristics:  132 mm x 430 mm x 470 mm (H x W x D)  Weight: 12 kg about Climatic and environmental characteristics:  Operating temperature: -20 °C to +55 °C, 95 % relative humidity at +40 °C (non-condensing)  Temperature storage: -40 °C to +80 °C 40300041 V2.4 40300041 V2.3 This sheet is available

SERIES 900 EQUIPMENT  TRANSMISSION SECTION  RECEPTION SECTION Power consumption:  Typical at 24 VDC: < 12 A  At 115 VAC: < 4.4 A  At 230 VAC: < 2.2 A Output power (at 24 VDC):  ≥ 50 W as a nominal value can be reduced to 10 W by the user  > 30 W for NL version (A3E > 144 MHz)  Reduced power: adjustable down to 10 W  Reduced power on load mismach = normal operation up to SWR = 2. Gradual power reduction for VSWR > 2. No damage on infinite VSWR. Frequency stability (between -20 and +55°C): ± 1 ppm Channel spacing: 25 kHz in AM and FM, or 8.33 kHz in AM Offset carrier generation (25...
