The Sailor 7222 VHF DSC Class A is a modern marine radio designed to support reliable, clear, and safe shipboard communications. This device is suitable as an essential part of maritime communication systems, whether for daily operational needs, ship-to-ship coordination, ship-to-shore communications, or emergency calls at sea.
In maritime operations, a VHF radio is not just an ordinary communication tool. It plays a major role in safeguarding the safety of crew, passengers, cargo, and the vessel itself. The Sailor 7222 serves as a next-generation VHF DSC Class A radio solution, featuring a practical interface, robust audio quality, and support for international maritime safety standards.
This radio can be used across various fleet types, including merchant vessels, workboats, fishing vessels, tugboats, offshore vessels, oil and gas industry support vessels, and government ships. With a design tailored to professional needs in the marine environment, the Sailor 7222 is an ideal choice for shipping companies and vessel owners who prioritize safety and uninterrupted communications.
The Sailor 7222 VHF DSC Class A is built to meet maritime safety communication requirements under the Global Maritime Distress and Safety System (GMDSS). This system is used internationally to support the transmission and reception of safety information, navigational warnings, and distress calls.
The Sailor 7222 is even designed to exceed IMO requirements for VHF Class A radios. This makes the radio suitable for vessels that require communication equipment compliant with international maritime safety regulations.
In addition to GMDSS support, the Sailor 7222 also adopts Bridge Alert Management provisions based on IMO Resolution MSC.302(87). This feature helps integrate alarms and important notifications on the ship’s bridge, enabling the crew to respond to specific conditions more quickly and in a coordinated manner.
This radio also complies with IEC 62923-1 and IEC 62923-2 standards introduced in August 2021. Compliance with these standards demonstrates that the Sailor 7222 is built to support the communication and safety needs of modern vessels.
One of the main advantages of the Sailor 7222 is its audio quality. Shipboard environments often have high noise levels from engines, weather, cargo handling activities, and other operational equipment. Therefore, clear communication is essential to ensure instructions are not misunderstood.
The Sailor 7222 is equipped with a 6-watt internal speaker capable of producing clear and sufficiently powerful audio. Sound remains clearly audible when used in the bridge, control room, shipboard work areas, or certain outdoor conditions.
In addition to the built-in speaker, this device also supports external speakers with audio output up to 6 watts at 8 ohms impedance. This capability provides flexibility for users to customize the audio system based on the vessel’s layout and operational needs.
With excellent audio quality, ship crews can communicate more effectively during voyage coordination, receiving safety information, monitoring radio channels, or handling emergency situations.
The Sailor 7222 is designed for easy operation by ship crews. The system consists of the Sailor 7226 VHF Transceiver Unit and the Sailor 7224 Control Unit. This combination allows for more flexible installation according to bridge requirements.
The Sailor 7226 weighs approximately 1.5 kg with dimensions of 161 x 306 x 51 mm. This transceiver unit operates within a temperature range of -15°C to +55°C, making it suitable for use in diverse marine environmental conditions. For storage, the device can withstand temperatures from -25°C to +70°C.
Meanwhile, the Sailor 7224 Control Unit features a 5.5-inch TFT display with capacitive multi-touch technology. This screen has a brightness level of 350 cd/m², ensuring information remains easily visible when used in high-light bridge areas.
The control unit also includes several important connectivity options, including LAN, USB 2.0, CTRL Port, ACC Port, and AUX Port. These ports support integration with additional devices such as handsets, hand microphones, GNSS, AIS, VDR, I/O alarms, external speakers, and even the Sailor 6204 device.
For voice communications, the Sailor 7222 operates within the frequency range of 156.000 MHz to 164.000 MHz. For DSC communications, the device uses the frequency 156.525 MHz. This radio supports all international maritime channels with 25 kHz channel spacing.
The Sailor 7222 can also be programmed with up to 100 private channels. This feature is useful for shipping companies or vessel operators requiring internal communication channels or specialized communications based on operational needs.
Transmit power is available in two options: 25 watts for longer-range transmissions and 1 watt for short-range communications. Users can select transmit power according to the situation to make communications more efficient and avoid interfering with unnecessary channels.
For voice reception, the Sailor 7222 has a sensitivity of less than -119 dBm at 20 dB SINAD. Meanwhile, the DSC receiver sensitivity is -117 dBm. These specifications help the radio receive communication signals effectively under maritime operational conditions.
The Sailor 7222 supports DSC operation according to ITU-R M.493.15, ETSI EN 300 338-1, and ETSI EN 300 338-2. The DSC system on this radio also complies with Recommendation ITU-R M.493-13 Class A, IEC 61097-3, and IEC 61097-8.
Digital Selective Calling (DSC) enables vessels to send digital calls to other ships or coast stations in a more targeted manner. This system is crucial for transmitting distress, urgency, safety, and routine calls.
The Sailor 7222 radio also supports navigator interfaces based on IEC 61162-1, including data formats GLL, RMC, ZDA, GGA, VTG, and GNS. With this support, the device can receive position, time, heading, and navigation data from GNSS systems or other navigation equipment on board.
