Although I believe that SA has not been turned on and that the gov't isn't interfering with the signals, I have noticed a lot of inconsistencies lately.
Inordinate amount of time to get a lock, EPE being reported in the range of 80-100 feet, days where my position is off as much at .25 miles, etc. The majority of days though, the position is spot on.
Today as I was driving to one, as soon as I crossed the border from New York into Conneticut I started loosing satellites (not just the lock but the view of them also). By the time I was at the cache I was down to two birds and only one lock ( found the cache by instinct). I didn't get a good position reading until I was several miles back into New York.
