I exchanged emails with the op at DP0GVN who advised me that he operates as time permits usually on 20 or 10 meter FT8. No schedules. But he advises that he is uploads to pskreporter and to watch there for his activity. The qrz page has an outdoor web cam.
DPØGVN is a club station located at the German Antarctic Research Station "Neumayer III" in Dronning Maud Land.
