9、 The TRP 9250 is a general purpose HF SSB transceiver designed for maritime applications covering the frequency range 1.6 - 30 MHz. The standard version offers simplex and semiduplex radiotelephone communication in the maritime mobile bands and is intended for installation in voluntarily as well as

10、compulsor- ily fitted vessels. With the optional built-in DSC and Radiotelex the TRP 9250 forms a inte- grated communication system ideal for simplified GMDSS installations. The TRP 9500 can be fitted in the SKANTI COMBRIDGE communication system for GMDSS. The TRP9250 consists of a compact Trans- ce

11、iver Control Unit, a fully remote controlled Transceiver Unit and an automatic Antenna Tuning Unit. The Transceiver Control Unit, Transceiver Unit and Antenna Tuning Unit may be installed 100 m apart using standard screened cables. One or two Control units are easily connected to the same transceive

12、r unit increasing the flexibility of the installation. The Transceiver Control Unit contains all re- ceiver and transmitter operating controls. It is fully push-button controlled by means of a splash-proof keyboard with tactile and audible feed-back . The LCD-display shows several information includ

13、ing receive and transmit fre- quencies, the mode of operation and time of day. Back-light with dimmer function is in- cluded for both LCD-display and keyboard to ease operation in any light condition. Mode, receive and transmit frequency set-ups can be stored and recalled directly from keyboard or u

14、sed in conjunction with the 10 scan programs. Sweeping of a selected frequency range is also possible with the sweep function. Where required by authorities transmitter frequencies can be preprogrammed into a PROM allowing transmission only on these frequencies. The compact Transceiver Control Unit

15、is easily in- stalled horizontally as well as vertically and with the optional rotatable wedge tilted to fit any installation. The Transceiver Unit contains all receiver and transmitter circuitry and all connections for ex- ternal equipment. The standard equipment has a built-in two-tone alarm gener

16、ator and single key selection of 2182kHz. A squelch circuit, an low noise RF-amplifier and RF-atte- nuator are also included. The transceiver is fully synthesized and the receiver may be tuned in selectable steps of 1kHz, 100Hz and 10Hz. The fully protected solid state 250W Power Amplifier, cooled b

17、y forced convection, mat- ches a 50 ohms antenna system, but is normally used in connection with the Antenna Tuning Unit. In the standard version, the transmitter covers the marine bands between 1.6 to 30MHz, but an optional PA-filter is available which give continuous coverage of the frequency rang

18、e 1.6 to 30MHz. The microprocessor controlled Antenna Tun- ing Unit tunes automatically to all antennas between 7 and 18 meters and requires no presetting at the installation. The typical tune time is less than to 0.5s. The TRP 9250 is designed for 24V DC oper- ation. Mains operation is possible wit

19、h the optional AC Power Supply Assembly installed in the Transceiver Unit. A Battery Charger Extension enables the AC Power Supply As- sembly to be used as a battery charger. The built-in test facilities and easy-to-replace module design of the TRP 9250 simplifies the service concept. GENERAL DESCRI
