Aeronautical and Maritime Radiocommunication Systems The EMRY990 unit is a VHF ground transceiver derived from the TELERAD 900 series technology which already proved its utmost reliability. overview Especially designed for voice communication in control towers, control shelters or ships, the EMRY 990 is provided with a receiver guard channel scan mode. The frequency range extends from 108 to 144 MHz VHF in 25 kHz / 12.5 kHz, or 8.33 kHz channel spacing according to ICAO annex 10 and ETS 300 676 standards. The channel spacing is implicitly given by the frequency value according to ICAO annex 10 rules: the equipment automatically switches to the right selectivity and audio frequency bandwidth. For transmission, the operator can, at any time, select one of two output levels : nominal power or reduced power (preset in 0 to -7 dB range). Up to 99 preset channels can be programmed by the operator, including for each channel the output power (high or low) and the squelch threshold level. The guard frequency is stored in the 99th channel at any desired value. A comprehensive front panel allows the equipment to be directly operated at a control position. In addition to microphone and headphones connectors, speaker and radio status indicators, the operator’s control interface is composed of a keyboard and a 4-lines / 20-characters-perline LCD, operated in «menus» oriented mode. In addition, the transceiver is provided with a serial data link and the required input/output signals for total remote control. The rear panel has separate RF connectors for transmitter and receiver section, and also a location for a coaxial relay, allowing the use of one common T/R antenna, or separate T and R antennas according the installation. The transceiver, is 19» wide and 3U high, and can be supplied in rack mounting or desk version. Two power supplies are available : 24 VDC voltage and 85-265 VAC mains voltage (EMRY990A) or 24 VDC only (EMRY990B). 40300074 V2.0 This sheet is available on the site www.telera
