This is one well documented example of an earlier unintentional jamming
incident.

Nigel-
I remember that event. This issue I'm remotely dealing with now seems
to be
limited to a specific local
area bounded by a few km. So local QRM is possible. On Saturday the
techs
identify a 3rd
party vendor equipment problem.
THANKS!

Does anyone know if there is ANY recent active Lightsquared testing
taking place in the SFO area of the US?
I'm dealing with a day-job issue with GPS clocks

We have about 25 different GPSDOs running from four cheap antennae on the roof

I guess any truckers with jammers on hwy 17 pass by so

Hi Brian:
Would you please let me know which antennas they will be using and if
this solves the problem?
Thanks,
Ron

I'm dealing with a day-job issue with GPS clocks in the Bay Area showing
GPS unlocked errors from 3rd party equipment.

Very unlikely.. they've lost their experimental license.

Interesting that they use jammers. The guys on the ambulances just wrap the
antennas with the foil from burger wrappers or the like.

I've had a graph logging on my HP3816A in San Jose. I see one big glitch
on 7/27 ~17:00 UTC. I don't know if it unlocked, nor if it was from
something received, or some jump in my hardware. Other than that one
jump, I don't see anything unusual over the last week or so.
There must be others
