Anyone using Leica system 1200 MDB data with teqc:

Yesterday it was brought to my attention that there were
certain Leica system 1200 MDB files from which teqc would
not extract GPS navigation messages from MDB records 115
using teqc versions up through 5 Apr 2006.  Since 5 April
there have been a number of changes to teqc to allow reading
of Leica's enhanced system 1200 GG MDB format ("GPS + GLONASS")
which is available on a new set of Leica receivers.  At any
rate, some of the tweeks made for the 1200 GG records allow
the previously unread 115 records to now be read, but I'm not
planning to release teqc executables until Leica has had some
time to see if the teqc decoding of GLONASS data is as expected.
But if you were experiencing difficulty with GPS nav extraction
from system 1200 MDB data, please contact me and mention what
teqc build you were using.
