Hello Felix,
first of all a big thank you for setting up a 630 m WSPR RX station in
Antartica.
At this moment there are very few stations active on 630 m in the southern
hemispere, I think your "best shot" is Roger, VK4YB, (QG62ku), but it is still
9000 km!
For a positive note: it is not exceptional for Roger to be copied at distances
of 9000 km or more (an extract for the past 14 days from wsprnet.org below). I
think it is a mather of finding the right moment (path in darkness), during the
given timeslot of 04-07 UTC is still daylight in VK4.

Onderwerp: Re: LF: Antarctica on 630m WSPR
Good morning!
Stefan, DK7FC, was kind enough to guide me to this group. I am one of the
operators of the DP0GVN beacon receiver and have just returned from
Antarctica after the successfull installation of the system.
We are using a Red Pitaya STEMlab system with a preamplifier to receive and
decode WSPR signals. The setup is quite versatile and can monitor up to eight
frequencies simultaneously. The antenne for the low bands is a delta loop
with a circumference of approximately 180m, about one mile south of Neumayer
Station III in an electrically very quiet environment.
We do not usually monitor 630m, but can do so at request. For the time being,
I have included 475.7 kHz daily in the time slot from 0400 UTC to 0700 UTC,
around our local sunrise. These times can be modified by request. Please do
not hesitate to contact me if you would like conduct tests on LF.
The receiver was on 630m all night long last night, but unfortunately no
spots were recorded, even though I know that quite a few stations tried.
We plan an upgrade to the beacon receiver next summer that will enable it to
cover more frequencies simultaneously. This would enable us to monitor LF
continously, but that won't happen until early 2019.
Laurence, I enjoyed reading about your previous trips to Antarctica. I never
got to see Neumayer I, have only been traveling south regularly since 2002
and spent one winter each at Neumayer II and Neumayer III.

Felix, DL5XL (DP1POL in Antarctica)
