Thanks, Nick. Went out today to check if the number box showed the same wrong numbers, and now it works as it should, both mast display and number box. Strange.

I am using Expedition (v. 11.0.14) to send calibrated BSP to mast displays. The system is based on NMEA2000, connected through an Actisense to the PC. Masthead displays are Garmins, the rest of hardware is B&G. Numbers are sent through one of the custom channels. BSP is ticked in the dialog box "Expedition calibrations" and the matrix filled in with reasonable numbers. The manual says Exp will add these numbers to the uncalibrated BSP. This it did last year, but this year the numbers on the mast displays are silly, showing 18 knots when the boat is doing 6. I literally have done nothing but update Exp.
What am I doing wrong?

I was wondering if anyone has tried getting Windows and Expedition to run on a Raspberry Pi. The newly released Pi 4 looks like a hardware that could run something like Expedition, and with the small footprint, low power consumption and ease of building a waterproof case (or hiding the little thing somewhere splash proof at least), it should be a good choice on board. If it is powerful enough, of course.

It turned out Windows needs to be set to using dot as decimal separator. Our locale dictates comma. Once that was changed, the log loaded fine. The joys of internationalisation :-)

When you say to leave first column as it is, what do you mean? In the Expedition log file, the first column is "Boat", the second is "Utc", then the different variables like BSP, AWA, etc. Should the first column be the timestamp "Utc"?
I was not aware of the KND LogCleaner. It wants another licence key, so need to ask Sailing Performance for that.

Trying to import an Expedition log file into Race Replay. It fails, saying it cannot determine start and stop time in the log. In the Race Replay config file I have set DateTime to "Utc" and ticked "Expedition DateTime format". Should the log file be converted somehow to allow Race Replay to read it?

Thanks, unfortunately there is only one source listed, which must be the speed transducer.

I have not found a way to point the GNX displays to use a certain source for data. Agree that being able to filter out the raw data coming from the DST800 speed transducer would solve this particular issue. But it is a fudge, and as Nick says, much better to only have good, calibrated data on the network.

Do you have sensors transmitting on the NMEA2000 network, picked up by the CPU, calibrated, then re-sent as calibrated values? If so, how does that work, are there PGNs for uncalibrated and calibrated values, to differentiate between raw data and calibrated data?

The solution works. Many thanks, Expedition provided a good solution.
Maybe someone else reads this and can learn something, as I have.
With a system using so-called smart sensors transmitting their values directly into the NMEA 2000 network, you risk a classic garbage in, garbage out situation. The equipment vendors market these "easy installation" solutions, and they are easy to install. However, there is a price to pay: they do not give you easy control over the values the sensors transmit.
If you are concerned with having accurate data on your screens, use sensors connected to a server which calibrates and sends the calibrated value into the network. Perhaps in the future there will be editable calibration tables in the sensors themselves, which would solve the issue.
