Class D DSC VHF Marine radio JMC RT-2500

Compliant to EN 300 698-2, EN 301 025, EN 60945, EN 300 828, EN 60215

Transmits and receives on all 55 International Marine VHF channels selectable directly from the front panel or from remote control microphone.

A single press of the DISTRESS key in an emergency allows you to broadcast your ship's ID and GPS-derived data including your position coordinates, date and time in the DSC format. The keytop is protected against accidental keypress.

The DSC Position Send/Request feature allows you to transmit/receive GPS-derived position between your vessel and other vessels.

The Tri-watch function, activated by a single press of a dedicated key, allows monitoring on channel 16, channel 9 and one user-specified channel.

Remote control microphone with a backlit keypad for making user-settings or for instant selection of a desired channel without having to reach the front panel.

Programmable scanning of user-specified channels selectable using a dedicated key

A public addressing (PA) function is built in, and its output is available for connection to an optional external loud speaker.

A dedicated key for instant switching of transmit power between high (HI) and low (LO) levels, with automatic low power setting on mandatory low power channels.

Housed in a waterproof cabinet to ensure dependable service under the exacting marine environment

Sailor RT5022 VHF DSC

Thrane & Thrane has developed the SAILOR RT5022 VHF with a focus on creating a reliable and user-friendly VHF, not only for everyday communication, but also for critical situations where lives may depend on it. All this combined with Thrane & Thrane’s advanced technologies have led to the introduction of a state-of-the-art VHF containing revolutionary new features.

As a world first, the SAILOR RT5022 VHF introduces the Replay function for improved communication and safety at sea. Push the Replay button and the SAILOR RT5022 VHF will replay the important messages you may just have missed.

Thrane & Thrane has developed the SAILOR RT5022 VHF with the aim of making a durable and powerful tool. Much effort has gone into creating user-friendly menus and buttons, optimal displays, good audio, a carefully designed handset that fits perfectly in your hand, as well as easy and flexible installation. The display has been thought over like never before, resulting in separate menus, one for the most used standard VHF functionalities and one for the DSC functions. The design and positioning of the buttons have been well planned with large tactile buttons for main functions and tactile knobs for volume and squelch.

All functionalities fulfil the obligation to provide easy and intuitive operation while retaining the basic SAILOR merits; durable, reliable high-quality VHFs created for rough conditions at sea, combined with new technologies and inventions. The SAILOR RT5022 VHF aims to take history into the future.

Conforms to all relevant international requirements and resolutions as agreed by ETSI, IEC, ITU and IMO as well as other national requirements, i.e. ETSI EN 301 925, ETSI EN 300 698-1, ETSI EN 300 338, ITU-R M.493-11, ETU-R M.541-9, IEC 61162-1 and IEC/EN 60945 (CU5000).

SAILOR RT5022 VHF DSC Basic Configuration:

Transceiver SAILOR RT5022

The SAILOR RT5022 includes a very powerful transmitter, as well as a very sensitive, selective receiver, which reduces blocking and intermodulation from other VHF or AIS products installed. The integrated DSC functionality has been designed for ease of use. The built-in loudspeaker is both powerful and provides very clear sound quality. The SAILOR RT5022 can be fitted to any bridge, flush mounted or in a bracket. Installation is facilitated through a built-in switch mode power supply.

Handset SAILOR HS5001

The SAILOR HS5001 Handset fits perfectly in your hand and has high sound quality. The design reduces wind noise in the microphone and the speaker unit covers the ear very well, making hearing easier in a noisy environment.

Semi-intelligent Control Unit SAILOR CU5000

The SAILOR CU5000 has been carefully designed for use on bridge wings or other secondary operating positions. All primary VHF functions and quick muting of incoming DSC alerts can be operated from this unit. It has been tested as exposed equipment and is water resistant to IP66.
