Type / Model : HT4610 – TU 1150
SAILOR HT4610 / TU1150 MF/HF Transceiver Unit
Overview
The HT4610 (also referenced as TU1150) is the core transceiver unit of the SAILOR (formerly Thrane & Thrane) System 4000 MF/HF radio series. It delivers 150 W transmission power and is designed for medium‑ and high‑frequency maritime communications, featuring DSC (Digital Selective Calling) capability and full GMDSS compliance for ship‑to‑ship and ship‑to‑shore operations.
Key Features
-
150 W output power for robust MF/HF communication.
-
Wide frequency coverage: From approximately 150 kHz to 30 MHz (MF/HF band).
-
DSC Functionality: Integrated DSC watch‑receiver and Class A or equivalent capability for distress, urgency and safety calls.
-
Modular system design: Integrates with compatible control/display units (e.g., HC4500B / TCU1150 / Debeg 3105B) and automatic antenna tuning unit (ATU 1150 / HA4615).
-
Marine‑grade build: Designed for installation in shipboard radio rooms, aligned with GMDSS station requirements and IF channel standards.
Technical Specifications (Typical)
| Specification | Description |
|---|---|
| Output Power | 150 W PEP into 50 Ω load |
| Frequency Range | ~150 kHz to ~30 MHz |
| Power Supply | Nominal 24 V DC (or compatible shipboard supply) |
| System Compatibility | Works with System 4000 MF/HF control units & ATUs |
| Functionality | Voice + DSC + telex/data capable |

Applications & Benefits
-
Ideal for ocean‑going vessels, offshore support craft and other ships requiring long‑range MF/HF communication beyond VHF coverage.
-
Supports full GMDSS compliance for sea areas A2/A3 (depending on installation).
-
Modular design allows for flexible mounting: control panel on the bridge, transceiver in the radio room, ATU next to antenna etc.
-
If a unit is re‑conditioned, cost savings are possible while still maintaining full functionality.
Important Notes / Considerations
-
Although this transceiver remains supported, the System 4000 series has been discontinued by SAILOR/Thrane in newer product generations.
-
Ensure compatibility of your existing control unit, ATU and other system components before purchasing or installing this unit.
-
If acquiring a re‑conditioned unit, confirm that it has been fully tested and certified for operational use.
-
Installation must follow the manufacturer’s guidelines for antenna tuning, earthing, and power supply to ensure DSC and MF/HF transmissions meet IMO/ITU requirements.
