Narrative:
Location: palm springs, ca. At about XA30 local our flight lost communication with center, probably due to being allowed to fly out of radio range just prior to our normal descent point. When we re-established communication, lax was very upset and stated that they had been trying to contact us via ACARS. As luck would have it our ACARS was displaying a no communication light at this time. Lax then passed us to the appropriate frequency and we were directed to descend in a vectored, descending pattern. We received an ACARS message on landing telling us to contact ZLA on frequency 119.X. There were no further instructions from ATC or anyone else. Supplemental information from acn 349409: must have extensive no communication area east of san.
