[Difx-users] Questions on new digital back end for Russian geodetic stations {External} {External}

[Simone Bernhart]

we've been doing this for quite some time now with several stations.

If you are interested in some VEX/v2d example files, please contact me 
or your colleagues from the WACO correlator.

Cheers,
Simone
