Opening on 28 MHz after Aurora - Wed 12th May 2021

Wednesday the 12th of May 2021 was an unusual day. The first half of the day seemed to be dead on 28 MHz with very little happening which was probably due to an aurora in progress. From about 18:00 UTC onwards, it sprung into life. This is what I heard on FT8 up until 18:30 UTC...


Once it was obvious that the signals were getting stronger, I moved over to monitoring for WSPR signals...


A total of 20 stations were spotted from the northern part of Europe. What was unusual was that the band just seemed to stay open up till midnight and then stayed open overnight.

What was also unusual for me was that I was hearing the SE of the UK which is about 650kms away for several hours. These are some weak QRSS signals I got a grab of...


What was unusual was just steady the signals were. Normally with short skip on 28 MHz, the signals are fading. QRSS signals come in and fade away. On the 12th, the QRSS signals from the UK just seemed to be there at a pretty consistent level for hours. They never got that strong as can be seen from the WSPR reports below but the QRSS signals never really faded out either.

This was the day of the season where the band seems to stayed open to Europe overnight.

A connection with the aurora event or just coincidence?

Report on 40 MHz activity on the 8th of May 2021 ...by EI7HBB


Lloyd, EI7HBB reports that he was active on the 40 MHz band on the 8th of May and caught the extensive Sporadic-E opening. He managed to work S50B in Slovenia twice on SSB during the day as well as hearing S57RW and S5/M0MPM on FT8.


LLoyd also reports managing to complete a 40 MHz / 50 MHz crossband SSB contact with Hugo, ON6ID in Belgium at a distance of about 900kms. ON6ID was on 50.145 MHz and EI7HBB was on 40.680 MHz and the contact took place at 15:22 UTC. He also wonders if this was a first EI-ON crossband contact for 8-metres?

LLoyd was also heard in the Netherlands at a distance of about 1000 kms.

Modest day on 28 MHz - 11th May 2021

 


After the big Sporadic-E openings over the weekend, Monday the 10th of May was pretty subdued on 28 MHz with just 7 stations heard on WSPR. Tuesday the 11th of May was however somewhat better with 29 stations heard on WSPR on 10 metres.

It was nice to hear the ZB2TEN WSPR beacon eight times which I think might be running 200mW rather than the 100mW listed. 'Hear' might be a bit misleading in that the strongest signal was -24dB which is about 10dB lower than what I could hear by ear. It just goes to show the power of WSPR fir digging out those weak signals.


It still amazes me that I am listening to a signal coming from their little SOTABEAMS WSPRLite transmitter shown above into a wire antenna.

When there were no WSPR signals for a while, I switched over to monitoring FT8 and it seemed to be mainly the south of Spain, the south of Germany and the north of Italy. The only signal of note was 9G5FI from Ghana.

144 MHz beacon on Hawaii heard in California - Apr 2021


Back in April of 2021, there was an opening on 144 MHz between Hawaii and California, a distance of approximately 4074 kms.

The reports shown above are from Chris Arnold, N3IZN in California who heard the WPSR transmissions on 144 MHz from the KH6HME beacon on a mountain in Hawaii.

The tropo duct across the eastern Pacific usually opens up several times a year and allow signals from 144 MHz to the microwave bands to propagate through it. It's probably one of the best long distance VHF paths in the world.

28 MHz Report for Sun 9th May 2021


Sunday 9th May 2021: While the 9th didn't seem to be as good as the 7th & 8th, there were still lots of Sporadic-E signals on 28 MHz for most of the day. Again, I spent most of the day on WSPR with the receive map for me shown above.

This time, I heard 7 stations running 50mW or less.

When the skip went short, I managed to get two QRSS (very slow morse) plots from two stations east of London, about 600kms from me.


I also spent some time monitoring the FT8 frequency and I heard 279 stations in 36 countries.

Guest Post: 40 MHz band on 7th & 8th May 2021 ...by F1EIT

Thanks to José, F1EIT for the following information which forms the basis of this post.


Friday May 7th was surely a great day for the S55ZMS beacon with the first 40 MHz spots but also
for 8m Sporadic-E activity that increased on the 8th .

Joan EA3ERE put the first spots (PI4) for EI1KNH on the 23rd of April but I heard nothing on CW.

On the 7th of May, Michel, F6HTJ heard the EI1KNH beacon on CW but I still heard nothing!

Finally today the 8th of May, both Michel and myself heard the EI1KNH beacon on CW and we also were able to hear the S55ZMS beacon in Slovenia at the same time.

I have a lot of QRM in the 40 MHz ISM band (Industrial, Scientific, Medical) and sometimes also on the beacon frequency.

I am still using my 50MHz Hentenna with an ICOM 575A. I am also working on a 40MHz wire halo based on the G3XBM (10m) design and am also looking at building a YU7EF 4-element Yagi.

José, F1EIT

28 MHz report for Sat 8th May 2021

 

Saturday 8th May 2021: This was another day where the 28 MHz band seemed to be wide open with lots of Sporadic-E signals from Europe. I heard 358 stations on FT8 in 29 countries but that was only listening on the FT8 frequency for a few hours.

I spent most of the day monitoring the WSPR frequency instead and the chart of stations heard is shown above. As can be seen from the chart, I heard 3 stations running less then 100-milliwatts.

Beacons: These were the beacons heard.

QRSS: The best thing about listening to WSPR is that I can monitor for QRSS signals as well as they just 500 Hz or so below the WSPR frequency. I managed to get one screen grab of ON4CDJ in Belgium.


The Sporadic-E season has well and truly started at this stage and you can expect to see lot of signals on the 10m band from now until late July.

PSK Reporter website passes 20 Billion Reception Records


On the 8th of May 2021, the PSK Reporter website hit another milestone when it passed the 20 Billion reception records mark. As the image shows above, it was recording almost 1000 reception reports per second on Saturday afternoon as it whizzed past 20 billion.

The vast majority of these reception records are of course due to the hugely popular FT8 mode.


The chart above shows the most popular modes over a 2-hour period just after the site passed 20 billion.

The reception reports for FT8 are 46 times the size of those for FT4.

In terms of software used in the last 7-days, the WSJT-X suite is still the largest with 23,741. The next largest is JTDX at 9,935 which seems to becoming more popular. I think when I checked this a year or two back, WSJT-X was a lot more dominant.

The PSK Reporter website can be found here... https://pskreporter.info/

S55ZMS 40 MHz beacon heard in France - 7th May 2021


Jeff, F0FYF in the south-east of France reports hearing the new S55ZMS 8-metre beacon in Slovenia on 40.670 MHz on Friday the 7th of May 2021.

F0FYF wrote... "recycling is good .. an old 4-element antenna for Swiss TV, somewhat retouched for 40 Mhz with its reception amplifier and the beacon #S55ZMS is received intermittently #hamradio#radioamateur" (via Google translate) (Radio = Yaesu FT-897)

The beacon transmits in CW and PI4 and some of the decodes by Jeff are shown below...


The distance was in the region of 775kms which suggests that the propagation mode was short hop Sporadic-E.

In terms of short hop Sporadic-E, the 40 MHz band is worse than 28 MHz but better than 50 MHz. Under exceptional conditions, anything down to 500kms might be expected at 40 MHz.

Since this new 40 MHz beacon moved to its final location at the end of April 2021, it has been now been heard in Ireland, Portugal and France.

Big Sporadic-E opening on 28 MHz - Fri 7th May 2021


Friday 7th May 2021: This was the second big Sporadic-E opening on 28 MHz with 568 stations in 52 countries heard on FT8 (30th of April was 403 in 39). This wasn't even the full extent of the opening as I spent maybe 2 hours listening for beacons or WSPR signals.

The map above shows the big Sporadic-E opening to the centre of Europe and you can see the arc of double hop Sporadic-E stations further east.

The one signal of interest for me was VO1CH in Newfoundland, Canada which was probably double hop Sp-E and a hint of things to come towards North America.

Beacons: I also managed to log 11 beacons on CW...

WSPR: As the band was open to central Europe, I managed to hear a few stations on WSPR...


Even though FT8 is excellent for monitoring band conditions, I find WSPR more interesting in terms of trying to hear weak signals.

I understand the 50 MHz was also open on the 7th but I didn't check. I did try listening for the OZ7IGY beacon on 40 MHz but had no luck.

Video: Introduction to QRP ...by Dick, G0BPS


Mid-Ulster Amateur Radio Club in the north of Ireland hold online ZOOM presentations every few  weeks which they then post to their YouTube channel.

This week, they had a presentation by Dick Pasoe, G0BPS about the history of QRP (low power) radio operation. 

Many radio amateurs prefer the challenge of building their own low power radios and have the satisfaction of using something they built themself  rather than buying a 'plug n play' commercial radio.

 The video gives a general overview of what is involved.

Modest opening on 28 MHz - 6th May 2021


Thursday 6th May 2021: Another modest day on the 28 MHz with 302 stations in 43 countries heard on FT8. Outside of the Sporadic-E to Europe, a number of signals came through from South America, Africa and the Middle East.

Two signals of note were 5T5PA from Mauritania and 9J2BS from Zambia.

I did a few scans of the band during the day and I didn't hear a single CW beacon. 

I'll probably spend a few more days monitoring the band to see when the first multi-hop Sporadic-E opening to the USA occurs.

Opening to Siberia on 28 MHz - 5th May 2021


Wednesday 5th May 2021: This was an unusual day on the 28 MHz band in that the main opening seemed to be to the east with very little from the south. The furthest station heard on FT8 was UA0SU near Lake Baikal in Siberia.

As for the propagation mode? Probably multi-hop Sporadic-E but you can never rule out F2 on 28 MHz over those kind of distances.

A total of 157 stations in 25 countries was heard on FT8 on 28 MHz.

Guest Post: Experimental reception of the OZ7IGY 40 MHz beacon via meteor scatter ...by S57RW

Andrej, S57RW in Slovenia left the following comment on the blog today under an old post. Rather than leaving it there largely unnoticed, I am putting it up as a short guest post.

* * *


Wednesday 5th May 2021:  Today I tried to listen to beacons on the 8m band and around 09:30 UTC, I got two bursts from OZ7IGY in Denmark. 

Both had a duration of about 10-seconds. First, I got a part of the PI4 transmission but that was not long enough to decode. After 2-3 minutes, I got a second burst and copied part of locator and final carrier.

This one was quite strong about S5 to S7 and had a typical burst and after burst. Don't know if that is the right term but it sounded like typical strong MS burst. 

It may be worth listening in the morning when there are more meteors around :) 

RIG was IC-7300 and a dipole for 8m abt. 4m high N/S direction. 73 Andrej - S57RW!

* * *

As the map shows above, S57RW is about 1200kms from the OZ7IGY beacon in Denmark, an ideal distance for meteor scatter on the 40 MHz band.

Note that the Eta Aquariids meteor shower peaks on the 6th of May.

Looking back at the start of the Sporadic-E season on 28 MHz - April 2021

For every day during the month of April 2021, I listened from about 08:00 to 22:00 UTC every day for FT8 signals on the 28 MHz band. For the first few days, I heard only a few countries every day. The chart below shows from the 7th to the 30th of April.


As can be seen from the chart, the second week of April continued at a low level with just a few countries heard every day. The 10th was one of those exceptions in that I didn't hear a single signal  despite listening all day. 

The chart clearly shows that the Sporadic-E season started on the 15th of April with the third week being in marked contrast to the second week.

Lyrid Meteor Shower: For Sporadic-E to occur, there needs to be a supply of metallic dust from the residue of meteors burning up in the atmosphere at a height of about 100kms. The first real meteor shower of the Spring is the Lyrids which goes from the 18th to the 25th of April and peaks on the 22nd.

Was the early arrival of the Lyrids responsible for the Sporadic-E season starting on the 15th and 16th. The exact start and finish of the shower seems to be different depending on what source you look at.

The 23rd of April is for me always a main date for Sporadic-E. I just noticed every year from my logbook that it was a date that stood out. It's probably no accident that it comes just a day after the peak of the Lyrids.

Methodology & shortcomings: In hindsight, I probably should have recorded the number of stations and countries on a day by day basis but I wasn't really planning to record the start of the season. The chart was just an idea I had once the month was over.

I was able to extract the number of countries heard on FT8 from my previous blog posts but the exact number of stations heard wasn't good enough that I would have confidence in the data for a chart.

As we are still near the bottom of the solar cycle, most of the signals that were heard were via Sporadic-E. It might be more difficult to repeat this test near the sunspot peak as there could be a F2 propagation in the mix as well.

I'll make a note in my calendar and I might repeat the exercise in 2022 and see if the results are the same.

Sporadic-E on 28 MHz for 9 hours - 4th May 2021


Tuesday 4th May 2021: The 28 MHz band was open more or less continuously for about 9 hours from about 13:00 to 22:00 UTC with signals from most of Europe coming through via Sporadic-E.

A total of 358 stations in 42 countries were heard which is usually a sign of a reasonably good day. 

The main Sporadic-E opening seems to have been to Italy as can be seen from the concentration of stations on the map. While I wasn't able to do that many scans of the band, I did hear two Italian beacons on CW...

EI7GL 28218.0 IQ5MS/B 18:31 04 May IO51TU<ES>JN54AB Italy
EI7GL 28227.2 IW3FZQ/B 18:28 04 May IO51TU<ES>JN55VF Italy

The Eta Aquarid meteor shower peaks on the 6th of May and that should provide even more fuel for the Sporadic-E propagation. The season is only just starting.

Sporadic-E on 28 MHz - 3rd May 2021

 


Monday 3rd May 2021: Just another typical Sporadic-E day for the start of May with 234 stations from Europe heard on FT8 on the 28 MHz band.

The pattern has been much the same for the last two weeks. It starts off with FT8 stations appearing on the screen that were buried in the noise and I couldn't hear. 

Eventually the FT8 signals get stronger and I can actually hear plenty of them. I do a scan of the beacon band from 28.150 to 28.300 MHz and I hear nothing.

At some stage, the FT8 signals get stronger and I can see the S-meter moving up to S5 and above. When I do a scan at that stage, I might hear a weak CW beacon. I'll try WSPR and hear nothing. Once I go back to the FT8 frequency, it's full of signals.

Traditionally, CW beacons were used to show that a band was open and stations would call then on SSB or CW. They seem to have a lot less relevance now.

I heard just one beacon on the 3rd of May.

S55ZMS 8m beacon heard in Ireland - 2nd May 2021


A few days ago, I had a post up about the new S55ZMS 8-metre beacon in Slovenia on 40.670 MHz and how it was on-air now from its new location on the 30th of April 2021. Post HERE

Just two days later on the 2nd of May, Tim EI4GNB near Dublin reports hearing it.


The signal was down at -9dB and buried in the noise but it still made it through. The distance was around 1745 kms which is pretty normal for one-hop Sporadic-E.

S51FB in Slovenia also reports hearing it on the 1st of May but that would have been via tropo.

If you hear this or any of the other 40 MHz beacons then be sure to spot it via the DXMaps website.

Modest opening to Europe on 28 MHz - 2nd May 2021


Sunday 2nd May 2021: This was a reasonably modest day on the 28 MHz band with 198 stations in 37 countries heard on FT8. The map above shows what I heard. It's interesting just how the Sporadic-E footprints can be pretty small and clusters of signals from a certain region make it through. 

Notice the batch of signals from Sardinia and yet there was hardly anything from France for most of the day.

I did a few scans of the beacon band and I heard two...

EI7GL 28271.0 OZ7IGY 12:07 02 May PI4 -14 dB Q=74 1393 km <es> Denmark

As you can see from the second spot, I was messing about with the PI4 software to decode the signals from the Danish beacon.

I tried listening on WSPR for a while but it was useless. On 28 MHz, WSPR is fine if the band is open to say the UK, Netherlands and Germany because there are a lot of stations there sending out WSPR transmissions. There is a major lack of active WSPR stations on 10m in France, Spain and Portugal which means the mode is of little use for propagation tests in certain directions.
