Robert, thanks. That's about the time frame most of us near
Philadelphia saw the problems, too. However, I saw it last Tuesday, as
well.

Jim, that's the site I cited and is how I know Pawtuxet River was
doing GPS interference. I cited it because while I thought Pawtuxet
was too far from me for concern, I didn't know if it really could
interfere with my signal reception. They cite a 35 nm radius around
Pawtuxet. Not sure I agree with you that it's useful, since it caused
me and others problems on a good soaring day...

I had similar problems while flying in The Pacific Northwest. There is
a number of distinct spikes in the trace because of lost GPS signal
from the satellite. It happened couple of weeks ago.

Pawtuxet is one of several sites doing this useful service. As are
China Lake, Fallon, Nellis, White Sands...
