Hi Brendon,
We're still using GEMPAK6.10, but no problems with decoding have been
noticed(looking at log files). I have noticed the file sizes for the
ukmet.gem files are smaller than they use to be(less than half). The
data files go out to hour 36 instead of 72 hours now.

Hello,
We've noticed an issue with reception of UKMET grids, it looks like
surface grids have stopped coming in. Has anyone else noticed this?
One clue is our GEMPAK decoder logs:

Perhaps a table was recently changed? I just upgraded to the latest
version of Gempak 7, so my tables "should" be up to date. Seeing
similar behavior in WXP, so my prime suspect is a change by the UKMET
office. Any help is greatly appreciated.
Thanks,
Brendon
