3000km+ opening on 144 MHz from the Canary & Maderia Islands into Europe - 10th June 2021

Thursday 10th June 2021: This was a pretty remarkable day in Europe for long distance 3000km plus openings on the 144 MHz band. There is a LOT of information so I will split it up into three posts. 

This post is the first one of three.

This is a long report so scroll down to see the individual stations from the Canary Islands and the Madeira Islands. I'll put a propagation analysis at the bottom but it seems that depending on where the European stations were located, it was a mixture of tropo only, Sporadic-E & tropo and probably double-hop Sporadic-E / chordal hop Sp-E.

* * *

I'll start with EA8JK as he had the most impressive map from the PSK Reporter website.


There are an amazing eight paths that were in excess of 4000kms! This is well beyond the normal 2300km or so one-hop Sporadic-E limit.

Here are the FT8 paths for EA8JK and just look at how many stations that were in excess of 3000kms.

These are the paths for EC8AZE. Even though there are only three of them, anything over 3000kms on 144 MHz is worthy of a mention.

View from Romania: It's interesting to check the FT8 map for YO4GJH ...


The two EA8 stations were covered already but just look at all of those EA5 & EA7 stations in the south-east of Spain. The longest ones are over 2800kms which is 500kms or so in excess of the normal single hop for Sporadic-E.

There are no stations near Gibraltar or the south coast near Portugal. This to me suggests that it wasn't just a case of just one-hop Sporadic-E from Romania to Spain and then into a tropo duct to the Canary Islands. I think on this occasion we are looking at what was probably Chordal Hop Sporadic-E with the signal 'bouncing' between two Sporadic-E regions.

Mode of Propagation: Well, it's complicated! First of all, let's look at the tropo prediction map from Pascal, F5LEN...

It clearly shows the almost ever present tropo duct between the Canary Islands and Portugal. There has been reports of a tropo duct extending all the way up to the south west of the UK and the south coast of Ireland for the last few days.

I have included the map for EA8JK again below for clarity.

I think the western paths shown are via a marine tropo duct. These include Ireland, the UK, the NW of France and the west coast of Portugal.

I think for stations in Germany, the Netherlands and Belgium, we are seeing one Sporadic-E hop to the SW of Spain and then tropo to EA8.

I suspect the more southerly paths to the likes of Romania and Bulgaria were via chordal hop Sporadic-E. There was a 4000km+ opening from Portugal to Israel as well and this would tie in with a Chordal Hop / Double Hop theory.

However, other than the UK and Ireland, I don't think we can pick out any one of the other paths and be 100% sure what they were.

All we can be certain of was that the 10th of June 2021 was an exceptional day for long distance DX on 144 MHz.

Look at PSKreporter at CU3EQ, 4X/OM2IB, 4X1UN, 4X1GA, OD5KU, OD5VB, stations as well! A lot of distances between 3000-4000km. Amazing mixing of two regions of Tropo Ducting and two regions of ES.
