I'm rinexing some .dat files from a new survey-run site and suspect an
equipment failure in the first few days of its life.  At first I thought
the files might be getting corrupted during their ftp journey from a
microsoft to a linux system, but the onset is gradual with the first
obvious issues on day 161:

Since then attempts to rinex have yielded nothing but this sort of thing:

I've put the files at ftp://ftp.panga.cwu.edu/private/cpud_problem if any
one is interested in taking a look.
