I lost GPS signal south of Elko for about 50 miles today. The signal would come in and out, not sure if I was on the north edge of some jamming. I have never had any problems in that area before.

6/4 had GPS jamming out of China Lake. There is much activity out of that location and can affect areas up to 475 NM at high altitudes.
