Wed 7/15 fantastic day, but SPOT??

I soared from the Minden area down to abeam Independence then back to
Mono Lake before needing my engine to get home to the Bay Area. (I
also used the engine to get me to Minden.) As long as I stayed with
the clouds, lift was fantastic east of the Sierras. I saw 13 kts on my
averager several times, and 10 knots while dolphin flying. South of
Mono Lake, there were clouds that could take you to the Whites or the
Sierras and, since I'm a sucker for soaring the Sierras, I took that
fork in the clouds. Made it to abeam Independence before turning
around. Lift on the Sierras was spottier -- as usual, but still very
good.

When I got home and checked my SPOT messenger track was missing an
hour and twenty minutes -- a new record. The last message before the
dropout was at 12:10 PM PDT and the next one was around 1:30 PM. Did
anyone else with a SPOT have a similar problem today? If anyone wants
to compare data, my shared page is

but, as usual, it will disappear in a few days or a week.

Thanks for any help on this question.
