30th July 2020 - There was another impressive 4000 km plus opening on the VHF & UHF today from Cape Verde Islands off the west coast of Africa to the north-west of Europe.
The map above from PSKReporter shows the FT8 signals being sent and received by D4VHF in Cape Verde. The mode of propagation was the usual marine duct but it was unusual to see the conditions extend into the midlands in England.
One of the most unusual reception reports was from PB0AHX in the Netherlands for two reasons.
1) The distance at 4680 kms is just 100kms short of the IARU Region-1 tropo record which was from D4VHF to the Isle of Skye in January of 2020.
2) The path from the Netherlands was over a lot of France and parts of Spain raising the possibility that perhaps there was another mode of propagation at work for the northern part of the path such as Sporadic-E or Meteor Scatter?
These are the FT8 reports on 144 MHz in order of distance for NW Europe...

The tropo prediction map below from Pascal, F5LEN shows the sea path from Cape Verde...
70cms... The sea path was also open at 432 MHz.

It's always amazing to see a 4000 km plus path at 432 MHz.
Canary Islands... It's also worth mentioning that the sea path was also open from the Canary Islands to NW Europe...

It's always worth remembering that the distance across the North Atlantic from Ireland to Newfoundland is about 3000 kms.

I was also lucky enough to work EA8CSB on 432MHz FT8 on the evening of 30th July. What's quite fun is that we were both using vertical antennas. I didn't hear D4VHF on 432MHz this time, sadly!
