500W MF/HF Radiotelephone
newly designed 500W MF/HF radio delivers enhanced performance and stability

Features
The new JSS-2250/2500 Class A DSC MF/HF radio equipment features an intuitive user interface and advanced modular design that allows for a flexible installation approach.

6-Channel DSC Built-In
The MF/HF has Digital Selective Calling (DSC) as standard with a built-in 6-channel DSC watch-keeping receiver. You can transmit and receive digital selective calls for quick and efficient establishment of distress, urgency, safety and routine communication with other ships and coast stations.
In distress situations, the MF/HF sends an alert once you press the distress button. The integrated DSC watch-keeping receiver monitors distress alarms through continuous scanning of distress frequencies.

Display settings
The MF/HF uses a 3.8-inch high visibility LCD display, which you can adjust at your own convenience. The display has 10 dim settings and you can set the contrast up to 11 different levels. An integrated screensaver and the ability to assign a commonly used menu to a user key for direct access, are just a few of the possibilities.

Distress alerts
The MF/HF includes a prominent distress button, with features to prevent accidental activation. When in distress, you can send a DSC message instantly, transmitting your MMSI, position, time of position and nature of distress, enabling an immediate response for search and rescue efforts.

Digital audio
The MF/HF integrates an advanced digital audio amplifier, which increases the amount of power, making the receiving message loud and clear.

Connect a remote control
Getting a second operation display onboard is easy. Connect a second display to the transceiver and position the display at a secondary location on the ship. The second MF/HF station is fully operable and you can transfer saved channel data to optimize your operation.

Unified design
The display design allows you to carry out all operations simply by using the same unified keyboard layout as found in JRC’s VHF radiotelephone. The keypad is solid and responsive, which allows for precise operation. The keys are also backlit, making it easy to operate in low-light settings on the bridge.

NBDP (telex) option
Complement your MF/HF with the NBDP kit for telex communication with shore radio stations and with other ships. It includes a10.4-inch messaging unit featuring a color display with a variety of color backgrounds. The LCD gives you a bright picture with excellent color consistency, even when you are viewing the display from the side.

USB
The USB 2.0 port located on the front panel allows you to connect a mass storage device to save and load messages.

Remote Maintenance System (RMS)
JRC has the ability to cost-effectively monitor performance and functionality of all MF/HF models while at sea, significantly reducing downtime and maintenance costs.

Flexible installation
The new 250W and 500W come with a display+handset, along with newly designed antenna tuner, transceiver and power supply that fit into a 19-inch rack option.

Antenna tuner
Outside mounting available as standard. Built-in antenna grounding circuit. Same mounting dimensions as preceding model (JSS-296/596).

Self diagnosis
With JRC’s MF/HF radio equipment you can perform self-diagnosis checks on the display and transceiver, allowing for easy maintenance and more reliability. The results are directly shown on the screen and can be saved as a log (up to 10 possible) or printed (with optional printer).
