I just love it when a format which is standardized doesn't work. I needed three tries to get a working GPX file from my new Holux M-241. At least working with OPM, other programs seem to have less problems with it. The program which came with the logger didn't produce a workable GPX file, using GPSBabel to translate that failed file into a real GPX file didn't work either. Finally I succeeded by using the NMEA-file written by the Holux software and converting it to GPX in GPSBabel. Trying it at a weekend didn't help either with 16 hours delay before getting the mail that the import failed.

For the second track I uploaded I used BT-747 and it worked without a problem. I would have tried that for the first track as well, but I had deleted it from the logger before I found out, that the upload had failed. Now I only have to find some time (weekend) to turn that second track into a map. I will try JOPM this time. And I will try to get out a bit again and create another track (in the area I live there is still an unmapped village I can walk to).
