Over the last few years, there have been many reports of contacts on 144 MHz from South America to the Caribbean region via Trans-Equatorial Propagation (TEP). There have been no reports of similar openings on 144 MHz from Europe to Africa in the same time period.
On the 31st of March 2024, it looks as if finally there was a TEP opening when V51WW in Namibia managed to receive SV8PEX in Greece, a distance of about 6532kms.
This is the report from the PSK Reporter website...
SV8PEX V51WW 2m Q65 6524 km 19:08:02
Tom, SV8PEX reports... "Unfortunately I was too late sig went down, one way. I was using 500W and V51WW I guess 100. Me -15db the best". Tom also notes that they tried FT8 and no decodes were possible.
Alex, SV1NZX writes... "First confirmed TEP reception of a signal between EU and AF tonight by V51WW from SV8PEX on 2m band after almost 40 years since the last signals between AF and EU intersected. Mode Q65a/30s "
Analysis... As the map shows above, both stations are about equidistant from the Geomagnetic Equator and are crossing it at right angles, an important consideration for TEP signals at 144 MHz.
As SV1NZX mentions, there used to TEP contacts on 144 MHz from Europe to Africa back in the 1970's when there was activity from Zimbabwe. The key thing is the location. Zimbabwe and the north of Namibia are far enough north for signals to reach the TEP zone. There are plenty of stations in South Africa (ZS) active on 144 MHz but they are much further south.
In this particular case on the 31st of March, it was a reception report but it shows that a TEP path was open at 144 MHz. Hopefully more stations in southern Europe will now beam south and see if the path is open to Namibia and the southern part of Africa.
It would be good to see more TEP reports from Europe to Africa on 70 MHz, 88-108 MHz and 144 MHz.

By the way, this is not an April Fools Joke! I know I posted it on the 1st of April so some might be wondering.
Thanks for the mention - there are more than 30 members across two different groups (TG and WhatsApp) talking about this endeavour. In fact, as a fun fact, it was given that, on 31/3/79 I4EAT had a QSO with Namibia for the first time.
ReplyDeleteThere are stations in ZD7, V5 and ZS4/6 on the one hand and I, EA6, SV, CT, 9H on the other hand, now given the primer, to start this most exciting period of testing.

That is a great report ! After several evenings of tests. Congratulations again!!
ReplyDeleteJust to mention that FR is also testing eTEP, I am a bit far east maybe, but who knows...
Too bad not much activity from North of FR, sure we may have TEP path too, so i am looking for candidates!!
I am almost qrv daily.
