Hi Greg. Sure, I'll just remove the extra code and let it through.
I *have* noticed that when my unit powers up, it can generate some strange

The station had been on the move for approximately 30 minutes when I noticed
it. From aprs.fi:

The station has noticed one or two odd posit reports shortly after powering
it up when he leaves home. I haven't noticed them on aprs.fi myself.
Possibly a similar issue to your powerup altitude error? I wonder if the GPS
receiver is reporting it has a reliable satellite lock when it doesn't.
Thanks for your feedback.
