Yup.  Sorry if you misunderstood that.  It is ALL 9-series.

Yup.  The epoch is wrong.

Let us know what you find.  We already know that every PPP service rejects
some valid RINEX files.  We know that some PPP services, like NRCan, are
happy with the gpsdrinex files from 8-series, and from other vendors
L1/L2.

So, beyond the known bad epoch, any other problem would have to be in the
drive_ubx.c decode of the new L2 signals.
