Raymarine Ray90, a full featured black box VHF radio with wireless handsets and Bluetooth audio

I believe that VHF radios from the big four MFD manufacturers are primarily offered so that boat builders and customers can put a single brand of electronics at the helm, and thus my normal advice is to consider VHF radios (and AIS transponders) from specialist manufacturers who may offer fuller-featured, better-performing equipment.  Testing the new Raymarine Ray90 makes me reconsider that recommendation…

FLIR Launches Next Generation Raymarine VHF Radios

FLIR is excited to announce the launch of its next-generation Raymarine VHF radios. The compact Ray53, full-sized Ray63 and the multifunction Ray73 with AIS are all full-function VHF marine radios with Class D Digital Selective Calling (DSC). Each new VHF model is equipped with a built-in GPS receiver and connection point for…

Vesper SmartAIS MOB simulation, a little known & nifty test tool

I often use and deeply appreciate the bundle of clever features that Vesper Marine calls SmartAIS, but darned if I didn’t miss one. While the WatchMate app screen above shows some aspects of the Vesper collision avoidance intelligence that makes this my favorite real-world AIS plotting tool (among many choices), it is actually a built-in simulation with significant benefits…

Hella Marine – EMI dangers from LED lights can be prevented

The United States Coast Guard (USCG) recently published an alert detailing the effect of Electro Magnetic Interference (EMI) caused by some LED products, and the potential for electronic communication interference. Simple testing can identify whether there’s a problem, but the situation can be avoided if owners choose products that are certified to international standards.

USCG warns about LED lights interfering with VHF & AIS, wants test results

The USCG recently issued a Safety Alert about how LED lighting near VHF antennas can cause poor reception on attached radios, which of course includes AIS and DSC reception along with regular marine VHF audio channels. I’m surprised because I remember such problems coming up and being solved a decade ago, which was very early in the evolution of LED lighting…but…

Standard Horizon GX6000 bad and good news, plus new HX890 and HX40

What the heck? An AIS transceiver with a decent antenna up reasonably high can see other AIS transceivers fairly far away, but not 3,508 nautical miles! What’s actually illustrated here was a Standard Horizon GX6000 mistranslating AIS target positions into NMEA 2000, as strongly suggested by the photo below. But as bad as that glitch was, there’s already a firmware fix and the way the update operation works has further benefits.
