Samyung Srg-1150dn Installation Manual

The Samyung SRG-1150DN is a compact MF/HF radio transceiver designed for medium- and long-range maritime communication. It is fully compliant with Global Maritime Distress and Safety System (GMDSS) requirements and integrates Digital Selective Calling (DSC) and Narrow Band Direct Printing (NBDP) capabilities. Core System Specifications Power Output: 150W (PEP) for the SRG-1150DN model. Frequency Range: Transmit (TX): 1.6 MHz – 27.5 MHz (10Hz steps). Receive (RX): 500 kHz – 29.9999 MHz (10Hz steps). Emission Types: J3E (USB), H3E, and F1B (FSK).

Display: Integrated large 10.4-inch color LCD for easy information reading, especially when used with the SN-100 NBDP terminal. Installation Requirements

Power Supply: Requires a stable DC 24V (±15%) source. To meet IMO standards, an individual power supply like the Samyung SP-1250ADC is recommended. samyung srg-1150dn installation manual

Compass Safety Distance: To avoid magnetic interference, maintain a minimum distance of 2.4m from a standard compass and 1.5m from a steering compass.

Antenna Exposure: Human proximity to the radiated antenna should not be less than 142 cm during normal operation to remain within safety limits. Initial Setup and Configuration The Samyung SRG-1150DN is a compact MF/HF radio

MMSI ID Input: Crucial for GMDSS functionality. Users must enter their unique 9-digit ship ID through the system menu.

PCB Selection: During initial service setup, ensure the correct PCB type is selected (e.g., T-474 for newer units) to avoid hardware conflicts. Reduce boat speed – turbulence may be the cause

Peripheral Connection: The SN-100 NBDP terminal and optional DPU-414 printer are connected via specific interface cables provided in the installation kit. Operational Features SRG-1150DN Service Manual Overview | PDF - Scribd

8. Testing & Sea Trial

| Test | Action | Expected Result | |------|--------|------------------| | Depth reading | Idle in >3m water | Stable number, no "---" | | Temperature | Compare with known thermometer | Within ±1°C | | GPS position | Mark a waypoint at dock | Returns to same spot | | Chartplotter | Zoom in/out | Smooth scrolling |

If depth is erratic:

Reduce boat speed – turbulence may be the cause.
Check transducer angle – should be slightly down at the rear.

Tools You Will Need

Marine-grade tinned copper wire (for grounding)
Wattmeter and SWR bridge (MF/HF frequency range 1.6–30 MHz)
Multimeter
Crimping tool for terminal lugs
Hole saw (for cable glands)
