It is great to see the list of stations with data yields <80% (from the CDDIS
status file for doy 260) is getting shorter. Most of the 19 stations on this
list were among the 29 stations listed last time, but a few new names have
joined. Hardware problems might explain some, but many probably still are not
recording L2 P-code data from GPS Block IIR-M and IIF satellites due a
receiver setting or translation issue.
