hi i know there has been alot of talk over the alphas and here is my problem in track point my best alpha was 24.455 in doppler was 23.729 and KA72 reader was 24.26 can i post KA 72 reader is this doppler now?? i have a GT-31 with V1.2 (b1405) firmware.if KA 72 reader is doppler i will post that.

ka72.com is in doppler, providing you upload the original .sbn or .sbp file, not a gpx file.

Dylan.

ok as far as dad and i have looked and studied it seem to be fine i have changed my results to KA72 i also checked my PB alpha from last year though your site and was 24.39 compared to what i got on real speed was 24.264 but wont be changing that.

Which software program did you use to analyse it at home?
Please email me you file and I will try to find the source of the issue.

just pm'ed you.
i don't think there is any issues just alot of variations between programs

That is the issue I need to look into.

I get identical 23.715 Doppler with both GPS-Results (v 6.70) and RealSpeed (v 1.929)
The only way I can get 24.6 is on trackpoints (and there is a obvious error in the trackpoints in that run.)

Now I check KA72 site it looks like you may have uploaded a .GPX file? Can you check that?
edit. Yep. When I download your file from KA72 it is a .gpx file and I run it in the 2 programs and get the same result from doppler - 23.715. I think that is the issue.

ok i uploaded my results on KA 72 in sbn file and got a 23.86 jybe.

this is what i got and its a sbn file uploaded and posted on gtc
