Opening to Antarctica on 28 MHz - 27th Oct 2021

Wednesday 27th October 2021: For a change, I decided to monitor the 28 MHz
band for WSPR signals even though I knew the level of activity would be dramatically lower than FT8.
FT8 is a really good mode for monitoring band conditions and seeing what
part of the world the 28 MHz band is open to. The problem for me is that
when things start getting too easy and every days looks the same then I get bored.
The same happens in April of every year. I start off looking for the start
of the Sporadic-E season with FT8 and seeing how it progresses. Once the
season gets underway and there are hundreds of stations heard on FT8, I get bored and move to WSPR.
On the 28th of October, I heard just 28 stations on WSPR as compared to the usual several hundred on FT8. Despite the low number, it was enough to make
it interesting.
The longest reception reports are shown below but it was nice to see VK2DVM near Sydney and the German Antarctic station DP0GVN make it through.

WSPR is far from perfect though. I heard nothing from North or South
America and this was more due to a lack of stations rather than a lack of propagation.

Most of the WSPR signals heard were due to a Sporadic-E opening to Europe.
The solar flux was up to 111.
