Disclaimer:  I've just relaunched and reconnected the cable running up my mast to my wind instruments.  This may be a connection issue, but...

I have an H2000 system onboard.  Old yes, but it's been bulletproof.

After getting everything connected, I started Expedition and noticed that the TWS on Expedition seemed to be alternating between an accurate value, no value, and something at least 2X reality.

TWS displays just fine on my B&G ffd's and Zeus mfd.

Then when I switch the configuration from H2000 Perf to H690 the wind speed displays as it should?

Any suggestions??

PS>  I saved "raw data" files for both settings but can't find a way to attach them here.
