I am following Ptulp instructions to
1. Run VDR with the Hartmut nmea file.
2. Use the timer to make 1 minute entries into the Meteo and Navigation
3. It is working and the file is about 1/3 complete.
4. When complete I will test the Polar_pi and export the file and upload for use during testing.
Thank you Ptulp
Edelvoilier, Thank you for uploading the Logbook database files. I will certainly try them too. Yes, your testing of Polar_pi would be very helpful. Any ideas for improvement such as better filters etc would be great.
