NAVTEX RECEIVER MAIN FEATURES: A wide dynamic range/high sensitivity receiver assures reliable reception of NAVTEX messages in the presence of strong local IF and MF broadcasts on adjacent frequencies. An efficient, static discharge-protected whip-type active antenna is supplied as standard, permitting limited space installation without sacrificing sensitivity. If preferred, a long-wire antenna can also be connected in place of the whip. For small vessels that do not requie long distance reception, a 60 cm long whip type active antenna with reduced receiving performance is optionally available. User-friendly man-machine interface makes the equipment easily programmable to receive only desired stations and message categories while allowing automatic printing of SAR, urgent weather warnings and other vital information on navigational safety. Stores a total of 128 received message IDs to avoid repeated printout of the same messages, thereby saving recording paper. Received messages can be output in universal text format via a devoted connector for use in onboard or shore-based applications. An optional audio interface board allows printout of NAVTEX messages received on other onboard communi- cations receiver. A built-in comprehensive self-diagnostic function checks hardware and software integrity and prints test results in an easy-to-understand format in the remote event of questionable performance.
