Recently we released the Navico Radar plugin 3.0 for OpenCPN (br24radar_pi). This plugin for OpenCPN (running on Mac, Linux and Windows) currently supports the older BR24 radar, the 3G and the 4G. The plugin provides most features you expect from radar software, such as:<br />- Anonymoushttps://www.blogger.com/profile/05734063490805449373noreply@blogger.comtag:blogger.com,1999:blog-3086978695636448584.post-28582418961475268422017-03-01T19:16:28.471-05:002017-03-01T19:16:28.471-05:00Yes, I saw that post on SetSail.

Regarding...Hello Jochen,<br /><br />Thanks for the comments.<br /><br />Regarding the AIS, the vessel position reports are broadcast on the N2K network for all to hear. This is how most all N2K data is transmitted, and hence there is no notion of it being consumed by one device, and hence not available to another. It's like listening to an announcement in the airport.
