AREQ base station for post-processing in Pathfinder Office

For those working in southern Peru/Altiplano/Northern Chile (from Nico tripcevich):

Good news: Working through our california trimble rep (Isaiah Mack) I was able to get Trimble to review the Trimble base station list in the Differential Correction software and reinstate AREQ to the list.
Try to differentially correct some peruvian GPS data and if you click \”Update List\” in the base station list the AREQ station should now appear (as it used to before about 2004).

We just finished fieldwork in Ayacucho.
Using a GeoXH 2008, sometimes connected to a Zephyr antenna, mine are as follows.
