MF,
Well, several strong stations were TXing WSPR-2 last night on 630m.
The condx seemed to be quite good. FR5DH has got 35 decode from 3
stations, best reports were:

The path to FR5DH is not directly on the path to DP0GVN but the
landpath to cross for these 3 stations is similar or even more. The
rest of the distance to make is just across sea water.
I don't know, maybe it is much more difficult to get a decode on 630m
in Antarctica because it is so close to the pole, geomag stuff and so
on. Or, it could be an issue of RX sensitivity at that frequency.
The audio file to analyse would help.
Yesterday we (Rik) invited VK4YB to participate in the experiment but
he just started to TX again at 08:24 UTC.
Any more ideas someone?
For tonite i'll be back on VLF, continuing to try to pass the 5 char
message over to W1VD and K3SIW...
73, Stefan
