On my last two flights at Marfa Texas May 24 and May 10 I have lost
GPS navagation fixes for a few minutes on both flights. I have two
GPS receivers (cambridge GPS/Nav and a lx-7000) both units lost their
fix at the same time and came back together. Both flights are up on
the OLC if you want details. Anyone else have the same experience?
Is it anything I can fix?
