5900km+ opening on 70 MHz from the Canary Islands to Kazakhstan - 25th May 2021


Tuesday 25th May 2021: There was an extensive Sporadic-E opening on the VHF bands with openings all of the way up to 144 MHz. On 70 MHz, there was evidence of plenty of multi-hop Sporadic-E including the one shown above from EA8JF in the Canary Islands to UN3M in Kazakhstan, a distance of 5946kms.

The map above from the PSK Reporter website clearly shows the 3 hop zones. First hop to Spain & Portugal, second hop to the centre of Europe and the one lone triple hop to Kazakhstan.

While double hop Sporadic-E at 70 MHz is rarer than 50 MHz, it is unusual to see triple hop on the band. Sometimes this can be as much to the limited number of countries with access to the band as much as the difficultly of getting three hops at 70 MHz.

These are the reports from the PSK Reporter website for distances over 4000kms.

UN3M EA8JF 4m FT8 5946 km 09:49:14

It was interesting to see that EA8/DF4UE managed to hear Latvia as well.

From the Kazakhstan point of view, this is the map for UN3M...


...and for UN7MBH...

Curious if UN7MBH saw my signal? I was active on 70MHz FT8. Didn't see any UN stations at all. 73, Bas

Hi Bas, when I was checking his PSK Reporter log this morning, I spotted your call in there.
