The radiotelephone system consisting of the JSB-196GM that covers the frequency range of 1.6 to 27.5MHz and the NCT-196 DSV terminal with an internal DSC watchkeeping receiver conforms to the applicable regulations including the IMO performance standard and the national standard.
FEATURES
- Simple installation on small ship
Each equipment if of very compact design for simple installation on small ship. The GMDSS-based system consists of the JSB-196GM MF/HF Radiotelephone, the NCT-196 DSC Terminal and a DC-DC converter. The main unit of the JSB-196GM and the NCT-196 can be integrated as a stacked system and installed in a easy-to-operate place on the bridge.
- High expandability
The JSB-196GM can provide the HF E-mail communication capability by connecting a dedicated modem and a general-purpose personal computer.
- Easy operation
The JSB-196GM is designed for user-friendly operation using a single large control dial for frequency channel selection, mode setting and high/low transmit power switching. The NCT-196 integrates the DSC modem and the watchkeeping receiver in it, enabling operations to fully meet the GMDSS requirements.
- Digital signal processing(DSP)
The JSB-196GM radiotelephone uses 32-bit floating point DSP for digital signal processing in and after the IF stage. The DSP technology improves a number of functions including noise reduction and various types of interference rejection, ensuring enhanced performance.

The powerful SAM MF/HF system 5000 fully complies with
all GMDSS safety requirements and provides voice
communication, DSC and radiotelex. It is available in 150 W,
250 W and 500 W versions making it suitable for all types of
vessels, from smaller fishing vessels to large merchant vessels.
The radio telephone system fully complies with all installation
requirements for sea areas A2, A3 or A4. Each radiotelephone
is operated from the robust and compactly designed control
unit (CU5100) which controls the powerful transceiver
unit (TU5150, TU5250 or TU5500) and the fast antenna tuning
units (ATU5215 or ATU5515).
