Samyung Srg 1150 Service Manual 19 Jun 2026

Test the transmitter using a verified 50-ohm dummy load. Check the 15V switching command sent from the transceiver to the external antenna tuner.

Typically 1st IF at 45.000 MHz (high-order roofing filter) and 2nd IF at 455 kHz (narrow-band filtering). Sensitivity: J3E/F1B: Less than 2.5 µV for a 20 dB SINAD signal. Selectivity: Voice (J3E): 2.4 kHz at -6 dB. Data/DSC (F1B/J2B): 300 Hz at -6 dB. 2. Modular Architecture and Board Layouts samyung srg 1150 service manual 19

: Fully GMDSS, ITU, and IMO compliant for maritime distress and safety communications. Manual Access Test the transmitter using a verified 50-ohm dummy load

Detailed steps for inputting the ship’s MMSI ID and system configuration. Sensitivity: J3E/F1B: Less than 2

This baseline technical layer is used during initial installation or after swapping a main system board. It provides step-by-step procedures to enter the ship's unique into the firmware. Additionally, it instructs technicians on how to trim the transmission output levels, calibrate the Push-To-Talk (PTT) line parameters, and configures the physical Printed Circuit Board (PCB) dip-switch matrices to match the vessel's battery voltage profile. 2.
