The MA-500TR is a class B AIS transponder that offers modern navigation safety while matching the clean look of Icom's award-winning VHF and SSB radios. Give your helm a handsome, harmonious look for fraction of the price. If you want to contact another vessel, you no longer need to locate and punch in its 9-digit MMSI number - the MA-500TR does it automatically. AIS information is displayed on the MA-500TR's own modest (yet clear and bold) screen or, for those who want a larger screen, in an NMEA-standard data stream for use by third-party chartplotters or other onboard nav gear. When you want the best, get the best. Get Icom. Simply the best.

The MA-500TR is a Class B AIS transponder for Non-SOLAS vessels such as pleasure craft, work-boat and small vessels. Your vessels information will automatically be transmitted at fixed intervals or under base station control. The MA-500TR receives dual AIS channels (Ch. 87B and Ch. 88B) simultaneously and receives both Class A and Class B AIS information. Transmitted information by MA-500TR is:

  • MMSI code
  • Vessel name
  • Call sign
  • Type of ship
  • GPS antenna position
  • Ship's position
  • SOG (Speed over ground)
  • COG (Course over ground)
  • UTC date and time
  • GPS antenna type
  • PA (Position Accuracy)

    Simple operation
    The Plotter display looks like a marine radar display. North-up, course-up and range zoom from 0.125 NM to 24 NM are supported. The Target list display shows all detected AIS equipped vessels and targets. The Danger list display shows a list of vessels that are within 6 NM CPA and 60 minutes TCPA from your vessel. The Danger list can be sorted by CPA or TCPA order. In addition to these display types, the Detail screen shows various information about the selected AIS target.

    CPA and TCPA for collision-risk management
    When a vessel comes into the CPA and TCPA range, the vessel icon blinks on the Plotter dispaly and emits a beep sound. When connected to external audio equipment installed on the deck tower, the collision alarm function will alert you even when you are away from the AIS transponder.

    Individual DSC call
    When connected to a compatible Icom VHF radio. It's easy to make an individual DSC call. Select a vessel using the MA-500TR's cusor keys and then push the "DSC" button on the MA-500TR. It is not required to input an MMSI number manually.

    100 Waypoints memory
    Up to 100 waypoints can be stored on the waypoint list. The "MOB" button allows you to set a waypoint on your current position instantly.

    Safety-related message
    When the MA-500TR receives a safetey-related message from a Class A AIS transponder, the message icon appears on the Plotter display. Up to 20 received DSC messages are automatically stored in the log memory.

    3-line NMEA input/output
    The MA-500TR has 15-pin D-SUB connector providing 3-lines of NMEA input/output on the rear panel. The supplied NMEA connector cable simplifies the installation and connection to the VHF radio and other navigation equipment.

    GPS receiver comes with MA-500TR
    The MX-5000 GPS receiver is a 12 channel parallel GPS receiver with SBAS function.

    Boise River Watershed Watch Shows Volunteers Issues River Faces

    Having just wrapped up its ninth year, the Boise River Watershed Watch program is an increasingly popular citizen science program in Boise, Idaho. It takes interested volunteers and joins them with expert scientists from the U.S. Geological Survey (USGS) who teach them about the river’s health and sampling water quality using transparency tubes, dip nets and chemical test kits. “Our focus is to educate folks on the parameters that we measure, to give them an idea of the river’s health,” said Tim Merrick, public information officer at the USGS’ Idaho Water Science Center. “So they can collect data on the river’s conditions and get plugged in.

    New Benthic Underwater Microscope Captures Coral Wars

    Researchers from Scripps Institution of Oceanography at the University of California - San Diego have designed and built a diver-operated underwater microscope to study millimeter-scale processes as they naturally occur on the seafloor. The research team has observed coral turf wars, coral polyp “kissing” and much more using the new microscopic technology. Many important biological processes in the ocean take place at microscopic scales, but when scientists remove organisms from their native habitats to study them in the lab, much of the information and its context are lost. In a quest to overcome this challenge, Scripps oceanographers developed the new type of underwater microscope to image marine microorganisms in their natural settings without disturbing them.

    First Environmental Monitoring System For Baltimore’s Inner Harbor

    Baltimore’s Inner Harbor and the rivers that flow into it are important sources of water to Chesapeake Bay, popular recreation sites and the targets of an ambitious clean-up plan. But the city has for some time lacked an environmental monitoring system for tracking water quality in the harbor continuously. That is about to change, thanks to a collaboration between the U.S. Geological Survey (USGS) and Environmental Protection Agency (EPA). It will lead to the new installation of a suite of sensors that will provide the public and scientists with the first comprehensive, real time look at water quality in the harbor.
