But the OCPN right mouse click menu to open the radar control is still there and functional, right?
What's below relates to OS-Windows:
I'm sorry there is not much development help for BR24Radar_pi for the moment. We are busy on the new plugin called radar_pi. See: https://github.com/opencpn-radar-pi/radar_pi
And we are working against OCPN alfa 5.0, that's current
OCPN master, so the Windows binaries available are only working on OCPN version 4.99.0
If you are able to build from source or install OCPN 4.99 you can give radar_pi a try. https://github.com/opencpn-radar-pi/radar_pi/releases
(Note!-- if you run O4.99.0 all other plugins, except inbound, have to be rebuilt for 4.99 as well.)
