It's my understanding the IGC file will NOT be fine if a mouse type GPS is used, because it will be missing the NMEA sentence with the datum that is in use. With a Garmin GPS, the sentence is not sent only when the datum is changed, but with every data point. I also suspect the Garmin GPS sends a sentence identifying itself, which is recorded in the file, but I don't know that for sure. Perhaps Marc or other knowledgeable person can comment? -- Change "netto" to "net" to email me directly Eric Greenwell Washington State USA

At startup some GPS sends (even a cheap mouse type could do it) this data but to get a valid IGC file boot messages doesn't have to be in the NMEA stream. I sent you one example (Vali-ewa.exe validated this). Regards, /Janos
