Narrative:
We departed sfo and flew the porte departure. We were cleared direct czq. Short of czq VOR, we were given a heading to intercept J-92 around lidat intersection. Before the intercept, we were told to turn 10 degrees right and expect direct bty VOR we were given direct bty a few mins later. As we were flying direct bty, we lost communications with ATC. We later re- established communications and were told we had drifted into a restr area, approximately 10-15 mi. We were then given a heading to intercept the bty 115 degree radial, fuzzy arrival. We then continued and landed in las vegas.
