Raymarine’s new Ray90 and Ray91 modular VHF radios offer the convenience of two wired handsets and three optional wireless handset stations. Both models feature a commercial-grade marine VHF radio transceiver with the latest Class-D Digital Selective Calling, as well as a built-in loudhailer and fog-signal generator with an optional hailing horn. The 91 model also has a built-in Class B AIS receiver. Connect the 91 to your MFD and instrument network to see the position and identity of nearby AIS-equipped vessels. The basic system comes with a black-box transceiver module and a wired handset/speaker kit. The transceiver hides out of sight and offers connections for an optional second wired station or wireless hub. Wireless handsets have built-in lithium ion rechargeable batteries. To recharge, just place the handset back in its supplied dock. Each wireless handset even has a locator alarm in case you misplace it. Both models have an onboard GPS receiver and a connection for an external GPS antenna. The radios communicate with your other MFDs and instruments via NMEA2000 or NMEA0183.
