Well, the data that you're receiving is the from the Tridata and wind instruments... don't see why you're not getting the VHW unless the VHW information is dependent on having the HDG and HDM data... which would normally be coming from a fluxgate
compass.
Again, is your
autopilot on when you're doing this, since that is the only fluxgate
compass in your setup AFAIK. If the
autopilot isn't transmitting the HDG/HDM data, you probably won't get the VHW data either.. since HDG is probably required to give you VHW.
The Tridata can only give you VBW IIRC without a fluxgate compass.
The graphic may not give you the HDG/HDM/VHW information without having a standalone fluxgate compass connected to it.

You know what the first rule of sailing is? ...Love. You can learn all the math in the 'verse, but you take
a boat to the sea you don't love, she'll shake you off just as sure as the turning of the worlds. Love keeps
her going when she oughta fall down, tells you she's hurting 'fore she keens. Makes her a home.
