Thread-topic: LF: RE: Antarctica on 630m WSPR
Stefan  - this is great news. I installed and operated the still in operation 10m Antarctic beacon on Rothera base 6734S 6808W back in 79, and was a avid LF/MF listener then and seasonally could hear Eu and America NDBs; even Capital Radio in "London" on 1548kHz as it was then. Even watched BBC1 TV on 405 lines on a Black and White TV

As ever remote NDBs that were close to the Pacific or Atlantic ocean were strongest and some time Huge signals, especially West coast Pacific stations - and of course this predates digital/visual detection

Im sure there will be detection for Eu and Americas/SA, and perhaps ZL/VK but the geomag field can be kind of unkind in that direction at time.

Neumayer 1 was just being built on my first trip but got to speak to them and exchanged weather on HF in 82/82 when I was stationed at Faraday, Argentine Islands.

Our 420kHz 100W 40ft top loaded vertical NDB at Rothera (ROT) was often heard off continent. Is morphed a bit and moved freq since then Im advised

Cheers

Laurence KL7L etc

PS: Now it is up to the active stations how this will continue!

If we can leave a decode on their site, they will probably put more attention and enthusiasm into that 630m band, even if our 50 Hz sidebands are just rejected by 37 dB.
Alternatively we can reject them by 50 dB at 10W RF and stay here in a range of 1000 km.

Hi Luis,

Yes, play the ball!!!! You are in an excellent location and your signal is, i would say, in the TOP 3 of EU :-)
I'm still transmitting on VLF daily but if DP0GVN comes on air before 22:30 UTC i may give it a short try.
The greyline is reaching their location right now!!
Due to the always up to date image of their webcam i assume that they will upload sports immediately.

Nice to see the good news Stefan J

 

Now the ball is in our side. From 4 to 7 UTC may be a good window for North America too

Hi MF,

Since a few weeks the German Antarctic research station Neumayer III  (https://en.wikipedia.org/wiki/Neumayer-Station_III) is running a Red Pitaya on a wideband RX antenna to receive/decode/upload WSPR reports on up to 8 bands simultaneously. You may have noticed them already on the WSPR map on other bands. I saw regular spots on 160m from DL statations and other countries in EU.

They seem to have quite a good satellite internet connection. So uploading WSPR spots is no problem. They also run an up to date webcam showing an image for example here:
https://www.qrz.com/db/dp0gvn

One of the maintainers of the radio station there is Felix / DL5XL. I know him personally and, taking the idea of EA5DOM, i contacted him and asked if they want to try to receive on 630m as well. Yesterday i got an answer.

DP0GVN in IB59UH will receive WSPR(2) on 630m daily between 4...7 UTC now.

I asked them if they can extend the time to 20...07 UTC. Let's see.

So turn on your PAs and make a first contact from your continent to Antarctica on 630m! And spread the message into other reflectors, VK could be in a favorite position.
