Title: Looking for Samyung SRG‑1150 Service Manual (Page 19 / Rev 19)
Post:
Hi everyone,
I’m searching for the service manual for the Samyung SRG‑1150 (marine radar/GMDSS equipment). Specifically, I need the information on page 19 (or revision/version 19 if that’s what “19” refers to).I’ve already checked the usual manual databases and Samyung’s official site with no luck.
Does anyone have a PDF copy they could share, or know where I can download the full service manual (not just the user manual)?
Thanks in advance for any help.
Service Manual Overview: A 47-page technical document covering circuit descriptions and adjustments is available on Scribd.
Operating Manual: A comprehensive 104-page guide for daily use and setup is hosted on Scribd.
Official Downloads: You can also check for legacy documents on the Samyung ENC Support Page. Core Specifications Frequency Range: TX: 1.6 MHz – 27.5 MHz (10Hz steps). RX: 500 kHz – 29.9999 MHz (10Hz steps). Output Power: 150W (J3E mode), 100W (F1B), and 75W (H3E).
Power Supply: DC 24V ± 15% (Draws ~15A during transmission).
Channels: Supports all ITU maritime channels plus 300 user-editable memory channels. Key Service Tasks If you have a specific problem (e
Reprogramming MMSI: While in SSB mode (not DSC), press Func + 3030, then ESC, then DSC, then Menu to access the Self ID entry.
Initial Setup: The manual provides procedures for inputting the ship's ID and adjusting transmission output and PTT settings.
Circuitry Breakdown: Service documentation includes details on the motherboard, synthesizer, power amplifier (PA) board, and wireless receiver components. Troubleshooting Indicators
LED2 (T-553): Should flicker regularly to indicate normal PLL/VCO operation. If it does not, there may be a fault in the synthesizer circuit.
DSC Reception: If DSC messages are not being received, technicians are advised to check the wireless receiver board and the 455kHz IF signal. SRG-1150DN Service Manual Overview | PDF - Scribd
In the Samyung SAR-1150 circuit diagrams, components are often numbered by type. "19" is commonly associated with:
For professional technicians: Absolutely. Without Revision 19, you may misdiagnose the ALC fault or overheat the final amplifier during alignment. The updated parts list and PCB changes are essential for a reliable repair.
For boat owners: Only if you have advanced electronics experience (soldering SMD, using an oscilloscope). If you simply want to change the microphone or clean the keypad, you do not need the service manual—stick with the user manual.
For hobbyists: Consider joining a marine radio forum (e.g., RadioReference.com or Transmission1). Other users may share the specific alignment page you need without requiring the full 120-page manual.
If your manual section shows a diagram of the radio chassis, this is the mechanical breakdown. This is essential for replacing the speaker, microphone jack, or front panel.
Key Disassembly Steps:

This is the most sought-after part. Revision 19 includes:

Warning: Avoid eBay or random “manual download” sites. The phrase "samyung srg 1150 service manual 19" is often used as bait for bots—you may pay $9.95 for an old user manual or a virus.
Q: Is Revision 19 compatible with the SRG-1150D (DSC version)? A: Yes, the "D" variant shares the same RF deck. Revision 19 adds two pages specific to the DSC modem board.
Q: Can I use Revision 12 instead of 19? A: You risk misalignment. Revision 19 changed the bias current for the driver transistor from 80mA to 110mA. Using Rev 12 values would under-drive the final.
Q: Does the manual include the AT-1300 tuner? A: No. The SRG-1150 service manual covers only the transceiver. The AT-1300 has a separate service manual (current revision: AT-1300 Rev 8).
Q: My radio has a sticker “MOD 19” inside. Does that mean it matches the manual? A: Possibly—but not always. “MOD 19” on a board or chassis indicates a factory modification (Mod #19). You should still use the Revision 19 manual, but cross-reference with the Mod 19 technical bulletin (often included as an appendix).
Without the actual manual, it's challenging to provide a detailed explanation of "feature 19 — complete." Here are a few possibilities:
If you manage to get your hands on the service manual, it should provide a detailed explanation of what "feature 19 — complete" entails and how to use it.
