Implausible Time Records

I don't see what you're seeing.Â* But how could records be out of
sequence?Â* Maybe because my position apparently reversed while
thermalling during a GPS outage and getting one or two hits and then
another drop out, etc.?

Yes, it was from the vario which just started acting up.ÂÂ* The ClearNav

Lately I've been getting a boatload of GPS drop outs.ÂÂ* Maybe that's
because I'm close to the source of the interference testing or maybe
it's because I've cut my antennae cables to length in my cockpit.ÂÂ* I now
seem to recall reading that one should not shorten the cables. I know
about reflections due to wavelength/transmission line length, but I was
unaware that that would affect reception.ÂÂ* Do I need to acquire new
antennae?ÂÂ* The antenna that came with my PF portable was 10 meters
long!ÂÂ* Who needs a big bundle of cable under the panel?

For my last three flights I've been getting a message from OLC warning

means and what I might do to correct the problem? I've asked the
question on the ClearNav forum but haven't gotten a reply yet.

Here's a link to the file if that helps:

Noticed it was from the vario. I'll use a vario file today and see...

Looking at the file, there is an out-of-sequence issue:

Could this be the issue?
