Would you mind have a look at this observation of SamH? You're the G HD expertise here.
Thanks

I gave this a little bit more thought and from what I figured out, the issue lays in that radar_pi use exact range_meter, where garminHD uses range_meter -1. That means "fixing" the garmin range definitions was a ugly hack, it was whats broke the nautical viewing in the control-window.

I have since reversed the rangedefinitions back to what it was, and instead adjusted the range_meter where it is beeing sent/received. That is range_meters -1 when changing/sending range, range_meter+1 when receiving the message. With that it works like a charm and displays correct.

For seaclutter there is something strange going on. In radar_pi it can show som-ething like Status calm 100% when Im changing it from my 3010 plotter. I havent been able to compare the actual packets yet, my onboard switch wasnt to happy with ettercap/arppoisening, Ill have to tap in to the network cable to catch packets. More results for that in a couple of weeks when Im back.

I'm closing this as we implemented the range fixes in PR #123
