The model WiNRADiO WR-G33EM is a powerful shortwave receiver, developed especially for
usage on ships. The frequency range starts at 9 kHz and end at 30.000 kHz.
Beside the classical modes of a shortwave receiver, like AM, SSB and CW the
WiNRADiO WR-33EM offers decoding programs for HF-FAX, NAVTEX, DSC and
TELEX. In the version WR-G33EM/GPS a GPS-receiver is included additionally.
Because of the high-resolutuion world maps your boat will be shown with the actual position
at any time. The WiNRADiO WR-G33EM offers good sensitivity and was optimized for reception in
conjunction with relatively short antennas.
In connection with the high dynamic range the model WR-G33EM is the ideal basis for communication
on board. The receiver is built into a small housing and has to be connected to a PC (not included)
via USb. The antenna socket is located at the back of the housing.
More functional safety by digital signal processing
 As the WiNRADiO WR-G33EM is a „Software Defined Receiver“, the special maritime signal decoding means no problem ana more. The signal has to be digitalized anyway and given to the signal processing. Data transmissions can be decoded easily this way and new modes can be added by software. Another advantage of digital signal filtering is the decoding of distorted or weak signals.
These functions are offered by the WiNRADiO WR-G33EM:
|
Digital Selective Calling DSC
The DSC-function of the WR-G33EM receives and stores security messages that are transmitted on emergency frequencies. The incoming messages are displayed and stored. They can be printed manually or automatically as well.
|
|
NAVTEX (Navigational Warnings by Telex)
The NAVTEX function of the WR-G33EM receives and stores security messages that are transmitted on NAVTEX-channels. The incoming messages can be filtered by content and geografic criteria. NAVTEX-messages are diswplayed and stored. Printing is possible here also.
|
|
HF-FAX Weather maps
The HF Fax function of the WR-G33EM allows to receive and store Fax-Weather maps. The receiver offers a largely automatic Fax reception, which requires only few actions by the operator. The received wather pictures may be zoomed, turned, displayed and stored or printed.
|
|
TELEX
The TELEX (RTTY) function of the WR-G33EM receives and stores text messages for maritime navigation that are transmitted on TELEX-channels. The radioteletype can be decoded in the modes Baudot and SITOR-B. Messages can be displayed, stored and printed. For more ease of use also the code filters BUOY, MAFOR, SHIP, SYNOP, SYN.MOBILE and PLAIN TEXT are available, which translate the special syntax and abbreviations into clear text.
