Late opening on 28 MHz - Mon 6th May 2019

Monday the 6th of May 2019 was in many ways similar to the previous day in that the 28 MHz band was quiet for most of the day and only really opened up in the late afternoon.

The main Sporadic-E opening started at about 15:30 UTC and what was unusual was that it didn't close until about 23:00 UTC.

The main opening was to the south towards Spain with most of the strong signals from there.

These are the FT8 signals heard on Monday the 6th of May 2019...


Notes...
1) The band opened to South America again although I heard a lot less traffic than on the 5th of May.

2) I noticed that some of the stations in the UK had double hop Sp-E down to the Canary Islands off the coast of Africa. There were no signals here though.

3) This is the map of Europe in more detail...


It shows the areas where the main openings were... to Spain / Portugal and to N.Italy/S.Germany.

The yellow line shows my one hop Sporadic-E limit. I heard just three stations that were double hop.

Beacons...While FT8 hears signals that are buried in the noise, hearing the beacons on cw is another matter. If you start hearing there then you know conditions are reasonable.

These are the beacons heard and they more or less concur with the areas heard on FT8...

The ED4YAK/B beacon near Madrid is one of the most consistent here and I heard it near the start of the opening and it was there for a lot of the evening. I also heard it at 23:05 UTC which was just after midnight local Summer time.

The one of interest in there for me is ON0RY/B in Belgium. This is reasonably close at about 1000kms which shows that the skip distance is getting shorter.

Caribbean... The most interesting part of the opening was probably the opening to the Caribbean. North-South propagation is the norm on 28 MHz when the solar flux is low but it's when the signals start going East-West that it gets interesting.

These are the FT8 signals from that region with Venezuela, Guadaloupe, Puerto Rico and Haiti heard....

North-South Divide... It was interesting to see how the signals from HH2AA in Haiti seemed to have a northerly cut off. None of the stations in the north of the UK seemed to hear him.

Stations hearing HH2AA on FT8 on 28 MHz - 6th May 2019
As for the mode of propagation to the Caribbean? One hop Sporadic-E to the west and then F2? Multi hop Sporadic-E?

I suspect Sp-E and then F2 but that's the thing about 28 MHz, there are times when you can't be certain.

The Solar Flux was down at 72 which is very low.

In total, I uploaded 304 FT8 reports from 188 stations in 30 countries to the PSK Reporter website.

These are the stations heard (2000kms plus in bold)...

Morning John

Another interesting day. Not sure if you saw anything of the OA station being worked by EA/CT 's last night. Nil my end,I ve not worked OA on 10m for a few years, also nothing to me from the Caribbean.
I did work TZ4AM on cw which was a nice surprise.

Good luck today.

Have not been active on 10m yesterday but see you saw my neighbourstation PA4O. Anyway, I noticed long ago that propagation on any HF band is most time better if you are living south. For instance the difference in propagation at Sunday was a dramatic difference between us.

https://pe4bas.blogspot.com/2019/05/unexpected-10m-paths.html

I even see much difference between station in the south and north part of my country and in the past a good friend of mine that lives about 50km south of me always worked the DX earlier then me, before I could even hear the station, yes that much difference...

Hi Steve, I did a quick check and I see that OA1F in Peru was heard as far north as Brittany by F4VPC yesterday.

Checking my blog for May, June and July 2018, I did hear Ecuador and the far north of Chile so it should be possible in the next few weeks if he stays on the band.

FB on the TZ, must keep an ear out for him.

Hi Bas

Interesting that you noticed the difference over just 50 kms.

I know the Sp-E footprint is sometimes oval shaped like a rugby ball. If the signal is coming from the east or west then the difference north and south can be dramatic.

Hi John

Nice site.

Good to see the SpE season well and truly underway, getting better by the day down here.
It was a good day indeed for SA.

btw am keeping my 10M RX on 24/7 where possible (TS590SG to a Hexbeam @40ft pointing due East) and feeding it to PSKReporter - hope it's a useful tool for others & gives me an idea of possible paths that may open on 6m :-)

Had some interesting 10M European openings during the night which have been quite unexpected.
Maybe I'll turn it to the West overnight if useful to anyone ?
