South African 8-metre beacon on 40.675 MHz heard in Greece - 6th October 2021

In a report by email, Leonidas SV2DCD in Greece informs me that he heard the ZS6WAB 8-metre beacon in South Africa on 40.675 MHz.

"Hi there John. TEP is back again on 8m band. Today me and SV8CS had copy from ZS6WAB/B 40.675mhz with peak around 16:50z best copy 539 qsb

Here is a video of my copy ZS6WAB/B @ SV2DCD via TEP 6/10/2021 16:40z 40.675mhz "

You can see a video of the reception below...

As outlined in the video title, Leonidas feels that the propagation mode was TEP (Trans-Equatorial Propagation). I have shown the Geomagnetic Equator in the map above and it seems to be roughly equidistant from both stations.

The distance was approximately 7,220 kms. Leonidas was using an 8-element Yagi for 50 MHz to listen to the beacon on 8m.

I also understand that the South African 40 MHz beacon has been heard in the south of Portugal in the last few days as well.

SV2DCD also reported hearing the same 40 MHz beacon in April of 2021. See previous post HERE

Now that we have concrete evidence of the 8m South African beacon being heard in Europe, hopefully others will try to have a listen and report it.

Analysis... This new 40 MHz beacon could prove very useful for serious 6-metre operators in Europe checking to see if there is a propagation path to South Africa. There is quite a jump from say 28 MHz to 50 MHz where as if the band is open at 40 MHz then 50 MHz may not be far behind.

Australia heard on 28 MHz - Fri 15th Oct 2021

Friday 15th October 2021: It wasn't a great day for propagation on 28 MHz but it was interesting all the same to see Australia coming through on FT8.

VK8NSB 10m FT8 14315 km 10:03:44

Everything is relative I suppose, it's down on other recent days but way ahead of the poor conditions at the bottom of the sunspot cycle two years ago.

There was some Sporadic-E from Spain and a reasonable F2 opening to Greece, Turkey, Ukraine and southern Russia.

A total of 151 stations were heard in 37 countries. The solar flux was 83.

EI1KNH 40 MHz beacon heard in Lincoln, England - Oct 2021

I got a recent email from Keith, G0RQQ to say that he was hearing bursts of the Irish EI1KNH beacon on 40.013 MHz recently. The distance is approximately 370 kms.

Keith, who is in the city of Lincoln, England heard the 15-second burst with a signal of S5 at around 08:15 UTC on the 13th of October 2021. He was unable to listen to the PI4 signals as he didn't have the software installed. 

Keith is using a Yaesu FT-817ND wide-banded, and the antenna is an end-fed wire 20m long and about 1.5m above ground.

It's just a reminder that it is very easy for anyone in the UK to listen to the Irish 40 MHz beacons during the early morning (~6-7am) when meteor scatter conditions tend to be best.

For EI1KNH/B, just leave your receiver on SSB about 800 Hz lower on 40.0122 MHz and you should hear the CW and PI4 tones eventually.

For more information on the 40 MHz band, check out my 40 MHz page.

Opening to China on 28 MHz - 13th Oct 2021

Wednesday 13th October 2021: The big openings to the USA on 28 MHz seemed to have eased back a bit in the last few days and no two days seem to be the same. The 13th of October was a bit like that with an F2 opening to the east but very little to the west.

A total of 200 FT8 signals from 39 countries were heard on the day but most of these were due to a  Sporadic-E opening to Europe. In truth, there weren't that many F2 signals in comparison to some of the openings of late.

The ones I found of interest were the signals from China which I think were the first for me this season. On 28 MHz, it's not always the stations that are furthest away that are the most interesting but it can be  those East-West signals with the most northerly path.

The solar flux on the day was at 84.

Signals from China...

Antarctica heard on 28 MHz - Sun 10th Oct 2021

Sunday 10th October 2021: I got a bit tired of listening for FT8 signals on the 28 MHz band so I decided to go back to WSPR instead. As I had expected, the amount of activity on this digital beacon mode was drastically lower.

I had the radio on from about noon on and as you can see from the map above, it's a bit sparse. I know that if this had been FT8, there would have been lots of stations heard.

The BIG surprise however was the German research station DP0GVN in Antarctica! Wow! 

It's always interesting to see Antarctica coming through but it's really nice on 28 MHz. According to their WSPR page, they run 5-watts on WSPR. 

The signal however was very weak here. According to the log, I had one single decode at -26dB which is well below what is audible by the human ear.

Looking at the map, there is other evidence of F2 propagation as well. During the Summer months, I used to hear VE1VDM in Nova Scotia via multi-hop Sporadic-E. On the 10th of October, it was very likely due to a single F2 hop as the solar conditions improve.

The solar flux on the day was at 85.

Addendum...

Related to 10m info  on https://ei7gl.blogspot.com/ I would like to add, that yesterday, during Makrothen RTTY contest, there was interesting and excellent 10m opening towards USA. This is extract from S53M log.

553 stations heard on 28 MHz - Fri 8th Oct 2021

Friday 8th Oct 2021: This was a really good day on the 28 MHz band with a total of 553 stations in 52 DXCC countries heard on the band.

The high number of stations was due mainly to two factors...

1) An extensive Sporadic-E opening to Europe which shows that even though we are in early October, there can still be Sp-E openings. It's not confined totally to the Summer months.

2) Good F2 layer opening especially to the eastern part of the USA. 

As always, it's the East-West propagation that it the most interesting rather than what rare stations popped up. If the maximum usable frequency (MUF) was struggling to reach 28 MHz then all of the propagation would be North-South. The fact that I'm hearing stations in the USA and Russia on 28 MHz probably means that the MUF to the south for me was up above 30 MHz and into the low VHF spectrum.

It's interesting to note the sharp cut-off of the stations in the USA at about 6500 kms. This was likely due to the limit of two F2 hops and there wasn't a third hop to go further.

For me, the most interesting station was AB6A in Oregon. Not so much because of the distance but because of the northerly path.

The solar flux on the day was at 93 which is on the way back up again.

FT8 / SSB... I know all of these reports are for FT8 signals but it just happens to be the easiest way to monitor band conditions. If you operate on SSB only then get ready for the CQWW SSB contest at the end of the month. I expect the 28 MHz band then to be excellent.

Big opening to the USA on 28 MHz - Wed 6th Oct 2021

Wednesday 6th October 2021: After a few modest days, there was a good opening on 28 MHz again with plenty of East-West propagation. Quite a number of FT8 from the USA were heard but the pick of the crop was W6IBU in California. 

That makes California interesting is not so much the distance but the fact that the path was well to the north.

It was also interesting to see Mexico coming through as well as 3B9FR on Rodriguez Island in the Indian Ocean.

Between the extensive worldwide F2 opening and the Sporadic-E to Europe, a total of 488 stations in 54 DXCC countries were heard.

The solar flux on the day was 85.

Here are the maps for the previous few days but didn't really warrant an individual post.

Opening to Texas on 28 MHz - Sat 2nd Oct 2021

Saturday 2nd October 2021: It looks like the 28 MHz band is on a bit of a roll at the moment with plenty of DX signals coming in from across the world every day. No two days are the same and the defining feature is how good the East-West propagation is.

On the 2nd, there was a very good F2 opening to the East but the multi-hop to SE Asia wasn't as good as the previous day. On the other hand, there was a good opening to the USA.

From my location in Ireland on the NW of Europe, the first and best F2 openings on 28 MHz are usually to the SE of the USA as this is the most southerly path. This turned out to be the case on the 2nd with a lot of stations from Florida making it through.

The most unusual signals were from Texas which required a more northerly path. This was another first for this season as these are the first signals that I have heard from the Lone Star state.

The Solar Flux on the 2nd was 87 and dropping. A total of 243 stations were heard on FT8 including 12 alone from South Africa.

The CQ WW SSB contest is coming up at the end of the month and I suspect all of the HF bands will be in great shape for it.

Opening to Australia on 28 MHz - Fri 1st Oct 2021

Friday 1st October 2021: The map above shows the 206 stations that I heard on 28 MHz during the day and it shows signals coming in from all over the world. 

Considering I'm only listening with a simple half-wave vertical antenna, it shows that the band is really begin to open up as we climb out of the sunspot minimum.

There wasn't much in the way of Sporadic-E propagation to Europe and the main mode was F2 as the solar flux is at 91.

For some areas of the world, it seemed that the limitation what the number of stations that were active rather than how good the propagation was. Here are some of signals...

VK8NSB from the north of Australia, the first VK this season. There is always something special about an opening to VK from Europe on the 10m band.

49 stations from Indonesia, 13 from Israel and 10 from South Africa.

D60AC from the Comoros Islands, FR4OO from Reunion, VU3RGB from India and 4S7AVR from Sri Lanka.

5H1FF in Tanzania, 9G5FIin Ghana, V51MA in Namibia and 5T5PA in Mauritania. 

It wasn't a great day towards the west with only one lone signal coming through from New Hampshire in the USA.

More US stations on 28 MHz - Thurs 30th Sept 2021

Thursday 30th September 2021: This was a mixed day in terms of propagation. On the one hand, a total of just 61 stations were heard on FT8 and there was a very little Sporadic-E propagation. The usual F2 opening to South America was subdued.

On the other hand, the was some interesting East-West propagation with stations further north in Russia and the USA coming through. It was also the first time I heard someone from Canada this season.

I have seen reports of plenty of DX on the lower bands where things are much easier in terms of propagation but I don't really have much interest in the lower HF bands.

The Solar Flux on the day was 95.

4800km+ opening on the Band 2 VHF band between Chile and Columbia - Sept 2021

In some recent posts, I noted how there was openings on 144 MHz between the Caribbean and Brazil via TEP - Trans-Equatorial Propagation. The distances were in the region of 4600kms.

As can be seen from the graphic above, there was also an interesting TEP opening further west with Band 2 FM signals at 102.7 MHz in the north of Columbia being heard in Chile in early September, a distance of just over 4800kms.

The recording below is from Felip, CE3SAD in Chile who is an avid FM DX-er.

Small opening to the USA on 28 MHz - Wed 29th Sept 2021

Wednesday 29th September 2021: This day was a little bit more subdued than the 28th of Sept but there was still a nice mixture of Sporadic-E and F2 signals on the 28 MHz band.

What was of interest to me was the small opening to the USA which is a sign of the more elusive East-West propagation. It certainly wasn't huge as I only heard four US stations signals on FT8.

Overall, a total of 99 stations were heard with the solar flux jumping up to 102 from 89.

Opening on 28 MHz to the Far East - 28th Sept 2021

Tuesday 28th September 2021: There was an extensive opening on the 28 MHz band with signals coming in from several continents as can be seen from the map above. 

If this map was for say 14 MHz then I'd be thinking 'so what?' but it's not, it's for the 28 MHz where we are just below the low VHF spectrum. At 28 MHz, we're near the limit of what is and isn't possible with F2 layer propagations.

What does the map show???

1) Sporadic-E to Europe - Despite the fact that it's the end of September, there are still Sporadic-E openings. Not only do these allow contacts in the 1000-2000km region but they also allow you to reach further south where F2 conditions are more likely.

2) Real East-West F2 propagation - Notice all those stations in the south of Russia, Turkey and the Middle East. That is genuine F2 payer propagation and it's East-West as opposed to North-South. That is a really good sign that we're coming out of the low point of the sunspot cycle.

It's also likely that if there were East-West openings on 28 MHz then North-South paths in the low VHF spectrum above 30 MHz were also likely to be possible.

3) Far East - This opening to Indonesia, the Philippines and Singapore was via multi-hop F2 layer propagation. I heard 38 separate stations from Indonesia in the region of 12000 to 13000 kms using a simple half-wave vertical antenna so conditions must have been good.

4) South Africa and South America - Possibly a mixture of F2 layer and TEP propagation. As already noted, it was likely that the opening in this direction extended up into the low VHF spectrum.

5) USA - This is the first time that I heard the USA this season and I wasn't expecting to hear it for another few weeks. In truth, it was barely open and it was what I would have expected i.e. the south-east corner of the USA. What was missing were the single hop F2 signals from Newfoundland, Nova Scotia and Maine.

In Conclusion... In total, I heard 368 different stations in 42 DXCC countries on 28 MHz on the 28th of September 2021. The Solar Flux was at 89.

If we are getting East-West propagation now on the 28 MHz at the end of September, I'd expect there will be some pretty good conditions in October and November.

Extensive opening on 28 MHz - 23rd Sept 2021

Thursday 23rd September 2021: There was a reasonably extensive opening on the 28 MHz band with FT8 signals heard from Indonesia to South Africa to Puerto Rico. There have been hints of various openings in the last week or so but this is the first time this season that it has been so extensive.

A total of 139 stations were heard with a combination of some Sporadic-E from around Europe and F2 propagation further afield.

The most unusual signal was D60AC on the Comoros Islands in the Indian Ocean.

All of these were heard with a simple CB vertical half-wave antenna.

The solar flux was 90 which is on the way back up again, it had dropped down to 73 a week earlier.

As it's only the end of September, it is still very early in terms of real DX. I suspect once we get to November, we might see some really interesting openings on the 10m band.

144 MHz TEP openings from Brazil to the Caribbean continue - 23rd Sept 2021

Following up on my previous post, the TEP openings on 144 MHz from the Caribbean to Brazil are still happening. On the 23rd of September 2021, there was a modest opening from FG4SU in Guadeloupe, FM5CS in Martinique and 8P6ET in Barbados to the south of Brazil.

The distances were all in the region of 4500 to 4700kms which is typical for Trans-Equatorial Propagation.

5000km+ paths on 144 MHz recorded in South America as the TEP season begins - 20th Sept 2021

It was interesting to note that there were several openings over the last few days on 144 MHz between the Caribbean and South America.

The map above shows the 5155km path that was open on 144 MHz between Aruba and Argentina.

P41E 144300 LU8FLB 00:59 20 Sep 21 Tep Argentina

The DX spot was most likely for a SSB signal and the propagation mode was TEP or Trans-Equatorial Propagation.

At around the same time, the path was open for FG4SU in Guadeloupe to the south of Brazil.

These are the FT8 spots...

FG4SU PY2OAL 2m FT8 4566 km 01:04:59

Notice how the signals from the two locations are different. At 144 MHz, only signals that cross the Geomagnetic Equator at right angles tend to get propagated via TEP. What this means is that stations near Aruba work Argentina while stations further east in Puerto Rico work the south of Brazil.

While I was looking up some information for this post, I noticed that there were also TEP openings on 144 MHz on the 17th and 19th of September.

It's likely there are going to be plenty of more openings between the Caribbean and South America on 144 MHz over the next few weeks. It would be interesting to see some reports of similar openings from the south of Europe to Africa.

Irish Amateur Radio Survey & SWOT Analysis Report 2021

The Irish Radio Transmitters Society (IRTS) conducted an online survey a few weeks back and the results are available now. You can view the PDF document HERE

A 64 minute video outlining the findings is shown below...

Opening to South Africa on 28 MHz - Sun 19th Sept 2021

Sunday 19th September 2021: The map above shows the FT8 signals heard on the 28 MHz band during the day. There were signals from the south of Europe which were probably via Sporadic-E and then longer distance signals from South America, St.Helena, South Africa and Namibia.

It's likely that the signals from the southern hemisphere were via TEP (Trans-Equatorial Propagation) with a single Sporadic-E hop at the northern end of the circuit.

The solar flux was down around the 74 mark.

While this was the first day this season that I heard signals from the south of the African continent, I could hardly say that the opening was exceptional. The two things to take from it are 1) There are openings on 28 MHz almost every day and 2) Most of the DX is on North-South paths.

We have a good bit to go yet before we see the East-West openings from Europe to North America on the 10m band for modestly equipped stations.

The DX heard on Sunday...

Polish contest station works 134 locators in recent 144 MHz contest

The Polish contest group SN7L were active for the recent IARU 144 MHz contest and it was interesting to see what they worked as it shows the potential of the 2m band.

The SN7L team were using 4 Yagi antenna system on the summit of a 1603m mountain in the south-west of Poland. Over the 24 hours of the contest, they managed to complete an impressive 1365 contacts with stations across Europe in 135 locator squares and 30 DXCC countries.

Some of the longest distance contacts were to Ireland, Scotland & the Isle of Man with distances in excess of 1500kms being recorded.

How often do we see articles for beginners which tell them that VHF is more or less 'line of sight'?

The reality is that the VHF bands have a lot of potential if people are prepared to put in the time and effort to exploit them.

Opening to Indonesia on 28 MHz - 14th Sept 2021

Tuesday the 14th of September 2021 was reasonably quiet on 28 MHz but one single station from Indonesia did manage to get through. It's likely that it was due to a weak Sporadic-E opening from my location to the north of Germany and from there by F2 propagation to Indonesia.

There was also a weak Sporadic-E opening to Spain later in the day. A total of 28 stations were heard on FT8. The solar flux was at 83 on the day.
