The Icom Black Box VHF Marine Tranceiver is a spacesaving unit that is ideal for owners of compact boats and shipbuilders looking for a black box solution.
The M400BB comprises only a black box main body and a supplied COMMANDMIC HM195 remote control microphone accessory. The two-piece radio set can easily be installed behind a wall or console-leaving a small or hidden footprint-and completely controlled from a remote position.
Although compact in size, the M400BB possesses the same robust functionality found in Icom's M424 VHF fixed mount. Features include Class D DSC and the COMMANDMIC intuitive soft-key interface design. Active noise cancelling, a 10W loudspeaker and public address (PA) are built in for optimal audio performance. The M400MB is compatible with Icom's MA-500TR AIS transponder for additional safety at sea.
Space-Saving, 2-Piece Configuration
The IC-M400BB consists of a two-piece, black box configuration. All function control including DSC operation, can be made from the COMMANDMIC™, HM-195SW, and the RF unit, IC-M400BB, can be installed in an out-of-sight place.
Intuitive User Interface
The menu system is shared with Icom's latest models. The bottom line of the dot-matrix display shows the software key functions which can be toggled with the left and right buttons.
Active Noise Cancelling
The built-in bidirectional active noise cancelling reduces background noise to up to 90% and improves both your transmitted voice and incoming call. Hear and be heard more clearly.
10W Loud Audio, Public Addres & Foghorn
Built-in 10W amplifier that increases the audio output from an additional external speaker. The public address function allows you to make an announcement from the microphone like a loud speaker, and the foghorn can also be emitted from the external speaker.
Built-in Class D DSC
The built-in DSC watch function monitors Ch.70 (DSC channel) actively, even while you are receiving another channel. DSC functions include: distress, individual, group, all ships, urgency, safety, position request/report, polling request and DSC test calls.
Common NMEA Interface
When connected to an external GPS receiver, current position and time are shown on the Commandmic display. When receiving DSC information from another vessel, the radio can transfer it to a navigational device via NMEA 0183 connectivity.
AIS Target Call With MA-500TR
When connected to the optional MA-500TR Class B AIS transponder, the AIS
target call function allows you to set up an individual DSC call from the MA-500TR.

If you live in a city, you may take the safety of the water that you drink for granted, although recent developments in Flint may have changed your mind about that. But for 45 million Americans who drink water that comes from private wells, drawn from groundwater and unregulated by a public utility, the question of what's in that water is an even bigger unknown—a potentially dangerous one. In 2016, the Environmental Protection Agency (EPA) released a report indicating that supplies of drinking water near hydraulic-fracturing or fracking sites are more likely to be affected by contamination events. Scott Jasechko and Debra Perrone, Researchers at the University of California Santa Barbara, wanted to find out just how many privately-owned groundwater wells might be at risk.Read More
In the wake of various water quality crises from Flint, Michigan and Puerto Rico, there is a growing interest and demand among consumers for home water testing. Enter DIY water testing kits like Tap Score by SimpleWater . Tap Score in particular was conceived of and launched by former UC Berkeley grad student John Pujol and co-founder and CTO Julio Rodriguez. “In 2015 we began testing small and rural communities for arsenic in their water,” Pujol explains. “We found it much more frequently than we expected, and also discovered that people in these towns greatly appreciated someone telling them what was in their water and how to fix it.Read More
For most of us, when we think of nitrate and agricultural pollution, we think of the nitrate that comes from fertilizers and leaches quickly through the soil. The effects of this kind of pollution are realized quickly, but researchers from Lancaster University and the British Geological Survey have recently revealed an underground time bomb of nitrate in rock. In the recent paper , lead author and hydrogeologist Matthew Ascott and the team quantified the vast amounts of nitrate that exist within the layers of rock between the soil and groundwater tables for the first time. They discovered that there is about twice as much nitrate lurking in this rocky vadose zone than there is in the soil—up to 180 million tons—nitrate that has been omitted from global scale nitrogen budgets.Read More
