Andy is correct -

On page 64 it also says "Temperatures below zero are expressed as -01
to -99".  The 0 is necessary according to the spec.

If you look at my raw data
(http://www.findu.com/cgi-bin/raw.cgi?call=kb0kqa&time=1) you will see
that my negative values, when they are single digit negatives, are
reported by xastir as -07 instead of -7.  Right now the temps are in
the double digit negatives (burr) so you'll have to look back a little
bit in the raw data.
