[aprssig] GPS problems in Los Angeles?

[Alex Carver]

Has anyone had a problem with their GPS receiver in Los Angeles on Friday, May 20 some time between 1200 and 1500 PDT?  I was driving around when my D700 started beeping wildly (I had beeps turned off on my GPSr).  The GPSr was showing me strange or impossible readings for almost an hour.  It would show speeds in excess of 100 MPH, altitudes of negative 90 feet or altitudes of 7000+ feet (my altitude at the time was 1000 feet).

Signal strength was there but the receiver was falling out of lock with the satellites.  At the time I was using the internal antenna and not the amplified external antenna.
