The main nav system on the boat is a Raymarine system with an itc-5 for converting the log paddle wheel signals into the system. On the Raymarine network the STW agrees with the SOG and seems to display sensible values.
A vYacht router transfers the SeaTalk NG / NMEA 2000 data to the pc / RPi.
Maybe somebody has encountered a similar issue and knows the solution or a possibility to calibrate STW values in opencpn or similar.
Thanks for the help in advance!
Look for the format the data is handlet . and presented . SignalK use SI units . So NM become KM . in Instrument Panel . you can chosse , what format you like to see .
