Trans-Atlantic opening on 144 MHz between the Canary Islands & the Caribbean
It looks as if there is a remarkable tropo opening in progress at the moment with EA8CXN on the Canary Islands making contact with several stations in the Caribbean on FT8 & SSB on 144 MHz!
These are some of the stations listed on the PSK Reporter website for the 27th of August 2020.

EA8DEC NP4BM 2m FT8 5236 km 23:30:14
Note the distance! Several are in excess of 5000 km which would be a new distance record for a 144 MHz contact across the Atlantic.
Back on the 8th of April 2020, D4VHF on Cape Verde worked PJ2BR on Curacao and the distance on that occasion was about 4759 km. It looks as if the new contact by EA8CXN to NP4BM in Puerto Rico has extended that record by roughly 500 km.
This is the tropo map from F5LEN which shows a marine duct across the Atlantic…
Note that this opening is still in progress and there does seem to be a remote possibility of an opening from the west coast of Spain & Portugal to the Caribbean!
Here are some of the screenshots of the FT8 contacts with EA8CXN.

Update – 28th of August – 13:17 UTC: The trans-Atlantic path is still open on the 28th.

EB1DJ 144174.0 KP4EIT 23:57 27 Aug TR FT8 -22 dB 1092 Hz Puerto Rico
Update – 28th August 2020 – 15:21 UTC: Alex, EB1DJ in the north-west of Spain reports that he got one single decode of the FT8 signal from KP4EIT in Puerto Rico.
EB1DJ 144174.0 KP4EIT 23:57 27 Aug TR FT8 -22dB
As you can see from the report above, the signal was pretty weak at -22dB so it was buried in the noise. It does however show the potential of the path and if the conditions are right, it may happen again.
To put this in context, the distance from NW Spain to Puerto Rico is just over 6000 km!
Update – 28th August 2020 – 17:10 UTC: Video of the SSB contact on 144 MHz between EA8CXN on Tenerife on the Canary Islands and FM5CS in Martinique. Just remember, this is just a 4800 km contact on 144 MHz across the Atlantic!
In this second video, EA8CXN completes another SSB contact with FG8OJ in Guadeloupe.
