Help with BRB 900 needed please

[Salvage-1]

I think I may have a problem with my BRB900. I have flown it various times, with and without the G Switch enabled in the setup program, also done tests ‘walking’ the transmitter around. Then I download the data to a .kml file, but then when I try and open it on Google Earth, I just get a line around the equator.
I have viewed the file with a text viewer and the data does seem to be there, but, for the two files I have, which are the last two flights, with G Switch enabled, I seem to only have data stored after the landing of the rocket.

I have attached files but renamed them from .kml to .txt , also included snapshot of the setup.

any help would be appreciated.

Open the KML file in a text editor (Notepad will work) and see if there's valid data, followed by a bunch of zeroes. If there are, clean out the zero lines, but be sure to keep the XML format intact. Save it under a different name, and try again.

No bunch of zeros.

header looks like

<name>gps</name>
<Style id="khStyle690">
<LineStyle id="khLineStyle694">
<color>ff00ffff</color>
<width>4</width>
</LineStyle>
</Style>
<MultiGeometry id="khMultiGeometry697">
<LineString id="khLineString698">
<tessellate>1</tessellate>
<altitudeMode>absolute</altitudeMode>
<coordinates>

Then lines of co-ords

-120.643523, 43.799202, 02998 <!-- 0 sats:9 UTC 20:22:32 -->,

Then

</coordinates>
</LineString>
</MultiGeometry>
</Placemark>
</kml>

When I try and take one of the co-ord lines , ie, -120.643565, 43.799207, 03015 <!-- 16350 sats:9 UTC 20:22:31 --> and then use the -120.blah, 43.blah, 03015 into Google maps, I have to chage it to W120.blah, N43.blah before it accepts it. I though the 03015 bit was the altitude, but that doesnt seem right with the progression I see in the file.

First flight was to 5295 ft (my mile attempt), second flight was to 3567ft.

Pads are 4250 ft above sea level.

did a meters to feet conversion of 1370 and get 4494ft which is close to the actual reported value in the stratologger.
2500 would equate to 8202ft, which means would show a difference of 3708ft, close enough to the recorded 2nd flight. So, conclusion is that the alt data is in meters.

Launch site is at N43 47.9721,W120 38.9119 (43.799535,-120.648533)

Looks like you are right about the reporting in meters.

-120.643565, 43.799207, 03015 <!-- 16350 sats:9 UTC 20:22:31 -->

reversed to
43.799207, -120.643565
works in Google Earth and Google maps

Min reported satlock was 5, average 7. That should have been enough.

Hey, I know that spot.

Lets guess... WSU Binder Excel rocket??

OK.. seem to have got the whole thing 'fixed'.

If I go to GPS Visualizer and get it to run the original files, it gives me a great output!

Outputted files and tracks attached. Option to color by altitude, etc, is nice.

Flight profile Both overlayed
Flight profile Flight 1
Flight profile Flight 2 altitude colored
