40 MHz signals from South Africa heard in Europe - 5th Nov 2021

Friday 5th November 2021: This was an interesting day for the 40 MHz band
with signals from South Africa reaching Europe and a big Sporadic-E opening
in Europe.

The map above shows the reports from the PSK Reporter website... Rcvr Band
Mode Distance Time (UTC)
SV1DH 8m FT8 6898 km 15:02:56
9H1TX 8m FT8 6828 km 15:02:29
G7PUV 8m FT8 8798 km 15:01:30
TEP Reports: Paul, G7PUV on the SE coast of England (JO00AU)
writes... "Willem ZS6WAB has been on 40.675MHz today using FT8 but I was surprised to get some decodes from him around 1500UTC. The path length is around 8800KM and his peak signal was -10dB although I've listened back to
my IQ recording and it was strong enough to hear quite clearly.
I think it's the first FT8 reception from South Africa in the UK on 40MHz,
and presumably all TEP as I had no reception towards EA/CT/I on 10 or 6 to suggest mixed mode."Reception of ZS6WAB by G7PUV

Thomas, DF6HT in the NE of Germany (JO63BT) writes... "Hi all, today
received for the first time a signal on 40.675, around 8minutes long was
the call from ZS6WAB who called there CQ, received here on a 15m sw
vertical For me a sign to check sometimes this qrg for some action, and
also a sign that North DL also have a chance to work on that interesting
band! 73s from Thomas, DF6HT"
TEP Analysis: Paul is using a log periodic antenna for the low VHF bands. I suspect that there may have been one Sporadic-E hop from G7PUV to the north
of Africa where the signals were coupled into the TEP (Trans-Equatorial Propagation) path to ZS6WAB.
It was probably the same for Thomas in Germany with one Sporadic-E opening
to the south.
The problem in Europe is that there can be an excellent Sporadic-E opening
to the south but as there are no stations in the north of Africa ,we hear nothing and think the band is closed.
Sporadic-E in Europe: There was also a very good Sporadic-E opening in
Europe on the day as can be seen from the report below and the report from Report from Borut, S50B... "Very good prop on 8m today in EU. As far,
EI1KNH have the strongest signal....599+++ on CW ever on my side. Hrd
EI7HBB on SSB too.
Hrd also EI1CAH/b and OZ7IGY/b. I forgot to monitor ZS beacon. Tomorrow....
I was also on 40662, but every time I was on this freq I have strong qrm
from some device only in dir of EI and US. I hope that till next year, qrm
will be lower/disappeared.
