[DG] [DG11]Windspeed values incorrect, too low, after some time, especially with more wind

Hi Kees,

Great news about the masthead wind, sadly they get a lot of bad press, but work harder than most onboard a boat, the top of a mast is a pretty hostile place, high 'g' forces, rapid movements and high shockloads, they also endure periodic seagull attacks too!
Aside from general maintenance to check the security of the main knurled nut, check for corrosion on the mounting block pins, you also need to consider the mast cable, some mast cables are supported inside the mast, others just hang from the top and so there are potential issues with fatigue too, so the voltage tests will help identify where the issue is more likely to be.

Yep - with the AIS700, please start a new thread, but a good starting point is update all software to the current version and thoroughly check connections, cables, and voltages!

All the best
Derek
