Opening on 28 MHz - Mon 27th Apr 2020

Monday 27th April 2020. A pretty modest day on 28 MHz with a hint of more to come.

The main Sporadic-E opening was to the south to Spain and Portugal.

There was a weak Sp-E opening to Germany but I was unable to hear any of the German beacons. This suggests that the band in that direction was just about open on 28 MHz and the Sp-E footprint was probably small and patchy.

In line with the conditions, just two beacons were heard...

EI7GL 28251.4 ED4YAK/B 11:30 27 Apr IO51TUIN80FK Spain

The most notable signal of the day for me was actually hearing MW0ZZK in the NW of Wales. I could actually hear his FT8 signal by ear even though he is some 280 kms away. This signal was direct and not via Sporadic-E, backscatter or the like.

That kind of distance might be common enough on say 144 MHz with tropo and beams but it's unusual enough on 28 MHz.

I also noticed that MW0ZZK had heard Indonesia and the Caribbean on 28 MHz during the day so there was some decent DX buried in the noise.

Opening on 28 MHz - Sun 26th April 2020

Sunday 26th April 2020. Another good day for Sporadic-E on the 28 MHz band although not as intense as the previous day. The map shows what I heard on FT8 when I wasn't using the radio elsewhere.

Beacons... I heard 13 beacons on 28 MHz during the day which is a sign of good conditions.

The unusual one was F5SN/B in the east of France which runs just 3 watts into a dipole. That was a new beacon for me and it looks from the Dx Cluster as if it may have been off for a few years.

WSPR on 28 MHz - Sat 25th April 2020

Saturday 25th April 2020. There was a pretty good Sporadic-E opening on 28 MHz with very strong signals from around Europe.

Rather than just logging hundreds of signals on FT8, I had a listen to the WSPR frequency instead.

I listened at two different stages during the day and the WSPR results were quite different.

When the band was wide open to Spain and Portugal with very strong signals on FT8, I heard just two signals on WSPR i.e. there is a lack of WSPR activity across the south of Europe.

By contrast, when there was a strong opening to the Netherlands and Germany, I heard plenty of signals.

What I find really interesting about WSPR are the stations running less than one watt output power...

It's amazing to hear signals from stations running 10 milliwatts and 50 milliwatts.

Beacons... The really good conditions also allowed a number of beacons to be logged...

The unusual ones were ON0RY/B and ED1YCA/B which are about 1,000kms from here and require short skip to be heard on Sporadic-E.

FT8... When I wasn't using the radio, I left it on the FT8 frequency on 28 MHz. As can be seen from the map, the opening around Europe was quite intensive.

Reception of the OZ7IGY beacon on 40 MHz - Sat 25th April 2020

There was a pretty intensive opening on 28 MHz on Saturday 25th of April 2020 with the MUF going up as high as 50 MHz.

After hearing the OZ7IGY beacon on 28.271 MHz, I had a listen for the beacon on 40.071 MHz and it eventually came out of the noise.

These were the decodes with the PI4 programme...

40M 13:30 UTC OZ7IGY PI4: S/N=-22 dB Q=64 T=-0.06 s F=3 Hz Carrier: F= Hz C/N= dB
40M 13:31 UTC OZ7IGY PI4: S/N=-1 dB Q=100 T=-0.06 s F=3 Hz Carrier: F= Hz C/N= dB

40M 13:38 UTC OZ7IGY PI4: S/N=-11 dB Q=100 T=-0.08 s F=3 Hz Carrier: F= Hz C/N= dB
40M 13:39 UTC OZ7IGY PI4: S/N=-15 dB Q=78 T=-0.08 s F=3 Hz Carrier: F= Hz C/N= dB
40M 13:40 UTC OZ7IGY PI4: S/N=0 dB Q=100 T=-0.06 s F=3 Hz Carrier: F= Hz C/N= dB
40M 13:41 UTC OZ7IGY PI4: S/N=6 dB Q=100 T=-0.06 s F=9 Hz Carrier: F= Hz C/N= dB
40M 14:16 UTC OZ7IGY PI4: S/N=-16 dB Q=82 T=-0.16 s F=3 Hz Carrier: F= Hz C/N= dB
40M 14:17 UTC OZ7IGY PI4: S/N=-20 dB Q=62 T=-0.15 s F=9 Hz Carrier: F= Hz C/N= dB

The strongest signal had a signal to noise (S/N) ratio of +6dB, the weakest -22dB.

Updated version of PI4 reception software... After a successful decode of the PI4 signal, there is the option to right click on it and spot it on the DX Cluster.

OZ7IGY Beacon website... These spots also appear on the OZ7IGY website. When I tried this a few days ago with an older version of PI4 (Ver 0.9.7.0), the spots didn't on the site. With the newer version (Ver 0.9.8.0), they do.

This is screen shot of the site showing the 28 MHz and 40 MHz spots from the 25th...

It worth noting that the various DX Clusters seem to handle the PI4 and 40 MHz spots differently.

DXWATCH DX Cluster... On the DXWATCH site, the PI4 spots sent from within the programme don't appear. The site also seems to filter out 40 MHz as it assumes it's a mistake as it isn't one of the usual bands. The spot above for 28 MHz from me was sent via the DXMaps website.

DXSUMMIT DX Cluster... On the DXSummit site, the PI4 spots appear successfully.

These are the spots on the DXSUMMIT site for OZ7IGY on the 25th of April 2020...

The spots from me shown as just 'EI7GL' are from DXMaps where I am a registered user.

The spots with 'EI7GL-@' were sent from within the PI4 programme.

Also note that EI3GYB also heard the beacon an hour later later at a location further north.

Conditions on 28 MHz - 23rd & 24th April 2020

Wednesday 23rd April 2020. There have been many big Sporadic-E openings on the 23rd of April in years past but alas, not this year. A handful of FT8 signals from around Europe were heard, a really quiet day.

Thursday 24th April 2020.  Conditions were marginally better with a hint of some DX.

Besides a small Sporadic-E opening to the south of Spain, there was a short opening to Brazil.

During the day, I also got single decodes on T8 from YC8DE in Indonesia and ZD7JC in St.Helena Island in the South Atlantic.

Quiet day on 28 MHz - Wed 22rd April 2020

Wednesday 22nd April 2020. A quiet day on 28 MHz and yet, a signal from South Africa managed to make it through on FT8.

ZS1XG 10m FT8 9900 km 15:35:44

There was a very weak Sporadic-E opening to the south-east of Spain but the FT8 signals were just about audible.

Good Sporadic-E opening on 28 MHz to Northern Europe - Tues 21st Apr 2020

Tuesday 21st April 2020. There was a nice strong opening on 28 MHz to the northern part of Europe with the MUF extending up as far as 50 MHz.

The opening started from here to Norway and Sweden and then moved south into Denmark, the northern part of Germany and the Netherlands.

The map of the left shows some of the FT8 stations heard during the day but it's incomplete as I only spent part of the day on FT8.

These are the beacons heard on 28 MHz...

As can be seen, only the beacons from the north of Germany were heard. The unusual ones were PI7ETE/B and PI7BXM/B from the Netherlands as it requires the skip distance to be shorter for me to hear them (~1000kms).

PI7ETE/B runs just 300 milliwatts into an indoor antenna. PI7BXM/B was a new one for me as I've never heard it before.

WSPR... I spent a bit of time on WSPR as well while the band was open. It's always interesting to hear those stations using less than 1 watt/

Opening to Denmark on 40 MHz - Tues 21st April 2020

There was a good Sporadic-E opening on Tuesday the 21st of April 2020 with three stations reporting reception of the  OZ7IGY beacon in Denmark on 40.071 MHz.

The screenshot above is from the DXMaps website which has a special page for 40 MHz reports.

Considering the low level of activity on the 40 MHz band, this page is normally blank so it was unusual today to see three traces on it!

These are some of the 40 MHz spots from the DX-Cluster...

EI7HBB 40071.0 OZ7IGY/B 11:36 21 Apr 539 Denmark

Lloyd, EI7HBB was the first to spot the OZ7IGY beacon on 40 MHz at 11:36 UTC.

I came across the 28 MHZ version of the beacon at 12:01 UTC during a scan of the band. As the 10-metre signal was strong, I then had a listen on 40 MHz and sure enough, the 8-metre beacon was audible. I spotted it on the cluster at 12:15 UTC.

The distance from the beacon is about 1350 kms for Lloyd and 1390 kms for me.

At 12:39 UTC, G7CNF spotted the  beacon from the south-west of England.

The PI4 in the cluster spot refers to the PI4 software which decodes the OZ7IGY signal which alternates between giving out its ID in morse and in PI4.

The amazing thing about the PI4 software is that it can hear the signal buried in the noise. At one stage, it decoded a -18dB signal and I could hear nothing.

More information about this beacon and the PI4 software can be found on the OZ7IGY website.

This is a screen shot of the PI4 software...

More 40 MHz & 60 MHz news from the IRTS

The Irish Radio Transmitters Society (IRTS) had some news updates (19th April 2020) about the new 40 MHz and 60 MHz bands recently.

EI1KNH is QRV on 60.013 running CW/PI4 for it's first e-season, which might be a good indicator that 4m is opening if anyone spots it ex-EI, and if any EIs spot it, it's a clear sign 4m and maybe 2m are available. It's located at the same site as EI4RF and EI0SIX, running 35w to a folded dipole at 1000ft ASL.

Meanwhile on 8m, the proposed EI1KNH beacon on 40.013 is on hold thanks to the lockdown, but will be deployed rapidly when the movement ban is Lifted. It will run CW/PI4 with 40w to a vertical monopole.

EI0SIX, which is /qrp at the moment, pending a PA and antenna upgrade - also ready to deploy as soon as the lockdown lifts. For anyone that has a MARS-Modded (non-SDR based) radio with 6m, they should be able to run on 40 MHz/8m, in RX mode at least, and the frequency to watch is 40.220 - this is the spot frequency LY2YR (Gintas) is allowed run on this season. He has a MARS modded FT2000 & a hexbeam ready to go.

At EI4GNB a MARS modded FT857d and a 2 element Quad are setup. Last year Gintas worked EI4GNB on 5m for a first, and what may be a 5m distance record, this year it's about 8m, which should be easy enough. Any EIs looking for a new band, or to set a distance record might want to get set for this. One word of caution, especially with 5m (60 MHz) - just because Your radio can be tricked into TX out of band does not follow that it will be clean or any use, this is especially true of the current crop of hybrid & SDR-cored radios.

Comparing an Icom IC7100 and an Icom 7300 for OOB use is night & day - the 7100 has acceptable emissions on 5m and 8m, but the 7300 has been found to be strongly not suitable. A general rule of thumb is, if it's in warranty, or just out of warranty, don't try to use it, get a transverter instead.

A beacon on 40.675 MHz is being run in grid KG46rc. The beacon uses an Icom Ic706 radio, 30 watts to a 5 element YU7EF Yagi on EU. So, with some luck, EI,

ZS [South Africa] and LY [Lithuania] can be worked on 8m this year.

Opening on 28 MHz - Mon 20th Apr 2020

Monday 20th April 2020. There was more weak Sporadic-E around Europe today on 28 MHz with 52 stations heard in 13 countries.

The most interesting signals for me were from the Canary Islands. As the list shows below, I heard eight EA8 stations on FT8.

I also managed to work AM8WARD on CW who had a genuine 599 signal.

That level of signal suggests to me that it was coming back off the F2 layer in the ionosphere and was not multi-hop Sporadic-E.

It just goes to show that the F2 MUF can reach as high as 28 MHz at 52 deg North even at the bottom of the sunspot cycle.

It was also my first contact on 28 MHz since July 2019!

Stations heard on FT8 over 2,500kms...

Short opening to Italy on 28 MHz - Sun 19th Apr 2020

Sunday 19th April 2020. It was another quiet day on the 28 MHz band with just a short Sporadic-E opening to Italy.

One late signal from the Canary Islands was heard around 21:00 UTC.

EA8AJC 10m FT8 2729 km 21:04:45

The map shows the signals heard on FT8.

I'd expect some sort of decent Sporadic-E opening in the next few days on 28 MHz and possibly 50 MHz.

Weak opening on 28 MHz - Sat 18th April 2020

Saturday 18th April 2020. The 28 MHz band was almost identical to yesterday except just weaker.

Again, there was a Sporadic-E opening to Spain and Portugal but the FT8 signals were pretty weak.

Just one station from Brazil made it through.

There was a modest opening to EA8 (Canary Islands) around 21:00 UTC which was about 1h 20m after sunset.

What's unusual about the Canary Islands is that it is about 2,700 kms from here, well in excess of a single hop Sporadic-E. This suggest some sort of multi-hop Sp-E path.

I also noted that one of the EA8 stations was working Australia...

Opening to Sierra Leone & St Helena on 28 MHz - Fri 17th April 2020

Friday 17th April 2020. Another pretty quiet day on 28 MHz and typical for April.

There was a modest Sporadic-E opening to Portugal and the west of Spain when the FT8 signals were actually well above the noise level. The footprint however seemed pretty narrow and I was unable to hear any beacons or cw/ssb signals on the band.

It opened to Brazil again with ZD7JC from St Helena and 9L1YXJ from Sierra Leone making an appearance as well.

These are the FT8 signals over 2,000kms in order of distance....

Opening to South America on 28 MHz - Thurs 16th Apr 2020

Thursday 16th April 2020. Conditions were slightly better than yesterday on 28 MHz with an opening to Brazil, Paraguay, Falkland Islands and St. Helena in the South Atlantic.

There was also a minor Sporadic-E opening to Spain and Portugal.

These were the stations over 2000 kms that were heard via FT8 on 28 MHz...

Hint of an opening to Africa on an otherwise quiet day on 28 MHz - Wed 15th April 2020

Wednesday 15th April 2020. This was one of those days where it seemed to be extremely quiet on 28 MHz. As usual, I had left the radio on the FT8 frequency of 28.074 MHz all day monitoring.

When I checked at the end of the day, I had heard a few European stations possibly via meteor scatter or possibly via aircraft reflections for the closer ones.

However when I checked the WSJT-X programme, I had two decodes as well from Africa, 9J2BS in Zambia and ZS1DX in Cape Twon, South Africa.

152600 -20 -2.3 1920 ~  KC3LEE 9J2BS -07
154230 -17 -0.4 2436 ~  IT9IHB ZS1DX RR73

I had decoded just one 15-second transmission from each station and as can be seen from the signal levels... -20dB and -17dB, the signals were buried well into the noise and well below a level I could hear by ear.

Propagation... When I checked who else had heard ZS1DX, I got the map shown top right above. Notice the footprint in the UK. It is a long narrow corridor and it seems to have been around the same time as when I heard ZS1DX, i.e. 15:30 UTC.

As for what happened? I suspect there was either a F2 or TEP opening to from Cape Town to the southern part of Europe. There was probably a weak Sporadic-E cloud somewhere over the western part of France where the MUF got up as high as 28 MHz for a while to allow the ZS1DX signal to extend from southern Europe up into the UK.

As with a lot of Sporadic-E openings, the Sporadic-E cloud was small so the footprint in the UK was small.... or at least narrow and elongated as I'd expect.

As to how I heard ZS1DX, it was possible just one lucky meteor burst over the Bay of Biscay to the south. This allowed me to hear for 15 seconds what the stations in Spain were hearing to the south. It's also possible that there was some weak Sporadic-E that got intense enough for a very short period to allow propagation of 28 MHz signals.

As for 9J2BS, there was no similar opening to the UK or northern Europe for him according to the PSK Reporter website.

Reception reports for the Danish 40 MHz beacon OZ7IGY - 2017, 2018 & 2019

The Danish OZ7IGY beacon on 40.071 MHz is at the time of writing (April 2020) the only operational beacon on the amateur 8-metre band.

While there have been some gaps in its operation over the last three years, this blog post is a record of who posted reception reports on the DX Cluster.

2017... The OZ7IGY beacon on 40 MHz was only spotted by these stations in Denmark... OZ2M, OZ5XN, OZ8ZS, OZ2PBS, OZ1QX, OZ1BNN & OZ1DJJ

2018... In 2018, some stations outside of Denmark posted reception reports on the DX Cluster...

OZ1QX < > JO65FQ
OZ5XN < > JO65GQ
OZ7AMG < > JO55KR

As the map shows, there was a marked increase in the number of reports from Ireland which is obviously due to the fact that there is now an allocation there for the new 40 MHz band.

Propagation... All of the reception reports outside of Denmark for 2018 and 2019 are in the range of 800 kms to 1800 kms. This is pretty typical of a Sporadic-E opening on the band.

It should be possible for anyone in Europe in that range to hear this beacon during Sporadic-E openings in May, June and July.

Dx Cluster... If you do hear the beacon then make sure to report it on dx-clusters like DXSummit or DXMaps as some of the other clusters ignore spots for 40 MHz as they assume they're a mistake.

Irish 60 MHz beacon EI1KNH/B heard in West Wales - March 2020

Back in early 2018, the 60 MHz (5-metre) band was allocated to radio amateurs in Ireland (EI) on a secondary non-interference basis. A new 5-metre beacon with the call EI1KNH became operational on the 16th of December 2019. See previous post.

It is on 60.013 MHz and runs 25 watts into a vertical folded dipole. This is currently the only 5-metre beacon operational in the world.

The new 5-metre beacon is co-sited with some of the existing Irish beacons - EI0SIX on 50 MHz, EI4RF on 70 MHz. The elevated site has a locator of IO63VE and is located about 20 kms to the south of Dublin.

On Sunday the 29th of March 2020, Steve GW0GEI in West Wales reported reception of the EI1KNH beacon on the DX Cluster, a distance of about 175 kms.

While there isn't anything particularly remarkable about this reception, it does seem to be longest reception report to date on the cluster.

It's also an excuse for me to remind people about this beacon on 60 MHz as we head into the Sporadic-E season. A lot of people will have SDR receivers that cover that portion of the spectrum and might well be able to hear it.

More info about the EI1KNH beacon in this previous post.

If you do hear the beacon then make sure to report it on dx-clusters like DXSummit or DXMaps as some of the other clusters ignore spots for 60 MHz as they assume they're a mistake.

Opening to Indonesia & Falkland Islands on 28 MHz - Tues 14th April 2020

Tuesday 14th April 2020. Despite what the map above would suggest, it was only a modest day on 28 MHz with most of the signals heard being pretty weak. Despite this, YB0BOB from Indonesia and
VP8LP from the Falkland Islands did make it through.

A total of 236 stations from 31 countries were heard on FT8 and the majority were of course from Europe...

The one notable feature on the map is the cluster of stations in Russia and Ukraine. This indicates the likely presence of double hop Sporadic-E which is the first major multi-hop opening of the new season.

Beacons... Despite all of the FT8 stations, just four beacons were heard which ties in with the modest conditions...

As we heard into the second half of April, we should start seeing more openings on 28 MHz and above.

FT8 stations heard that were over 2,000kms...

Opening to Thailand on 28 MHz - Mon 13th Apr 2020

Monday 13th April 2020. The big suprise on 28 MHz was the reception of HS5YLK in Thailand in SE Asia at the distance of 9,460 kms. This coincided with a reasonable Sporadic-E opening in Europe which was further to the north than usual.

This is a map showing the stations in Europe that heard HS5YLK...

Its interesting to see a small footprint across the south of the UK and Ireland and yet, there were no reports from the Netherlands and just one in Germany. There are large numbers of active stations there on FT8 but it looks as if they were in the skip zone for this particular hop.

In Europe, there were reasonable signals to the north of Italy, the north of Germany, Denmark and the south of Sweden.

Beacons... There were the beacons heard...

This was the first time I heard the Danish and Swedish beacons this year. There was no sign of the beacons from the south of Germany this time.

These are the FT8 station heard in excess of 2000kms...
