Humour: 28 MHz V 14 MHz

I came across this on Facebook and I thought 'Yup'! 😂😂

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.

More information about the OZ7IGY beacon can be found here... http://www.oz7igy.dk/

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...

Big opening on 28 MHz - Sunday 12th April 2020

Sunday 12th April 2020. This was the first proper opening of the Summer Sporadic-E season with an extensive opening to Europe and beyond on 28 MHz. A total of 524 stations were heard on FT8 in 35 countries.

As can be seen from the map above, the strong Sporadic-E conditions in Europe coupled into F2 and possibly TEP propagation further south. It just goes to show the potential of the band when there is some Sporadic-E about.

There are some interesting points to note from the map.
a) I heard 3 stations from Lebanon and none from Israel which suggests a small footprint.
b) Nothing from Norway, Sweden, Finland or the Baltic states as the opening was primarily to the south of Europe.

This is the European map in more detail...

The main Sporadic-E opening from Ireland was to the north of Italy as can be seen from the concentration of FT8 stations heard.

As can be seen, there was a lack of propagation to the northern half of Europe.

Beacons... As the FT8 signals got strong, I started listening around for some beacons...

I heard 6 beacons from the north of Italy including I3GNQ/B on 28.3217 MHz which also gives out a slow morse QRSS signal. It only uses 0.2 watts into a vertical which is a sure sign of just how good the conditions were.

As we move into the second half of April, the Sporadic-E openings on 28 MHz and above should become more frequent and intensive.

Stations heard in order of distance....

Historic first Trans-Atlantic contact made on 432 MHz - Tues 7th April 2020

On Tuesday the 7th of April 2020, a remarkable contact was made with the FT8 digital mode on 432 MHz between D4VHF on the Cape Verde Islands off the coast of Africa and FG8OJ in Guadeloupe in the Caribbean.

This was the first 70cms trans-Atlantic contact without using satellites or the moon. The most likely mode of propagation was marine ducting with the signal being trapped close to the ocean.

* * * * *

Update: Saturday 11th April 2020 - D4VHF in Cape Verde and WP3ND in Puerto Rico complete a contact with FT8 on 432 MHz. This extends the trans-Atlantic distance to approx 4,367 kms. Full info further down this post.

SEARG IRTS news moves to 8pm from the 14th of April 2020

The news from the Irish Radio Transmitters Society is broadcast every Tuesday evening on the Southern Ireland Repeater Network on 2m and 70cms.

As of the 14th of April 2020, they will be moving the time from 9:30pm to the earlier time of 8pm.

Opening to St Helena on 28 MHz - Sat 11th Apr 2020

Saturday 11th April 2020. There was perhaps a sign of things to come with a weak Sporadic-E opening on 28 MHz to the Iberian Peninsula.

The morning seemed pretty quiet with just a few signals heard.

In the afternoon, ZD7JC on St Helena Island was heard at about the same time as EA7HPI in the south of Spain.

It's likely that there was a Sporadic-E opening from Ireland to Spain around this time and then the path was either F2 or TEP (Trans-Equatorial Propagation) down to St Helena in the South Atlantic.

I saw a report of a TEP opening on 50 MHz between the USA and Argentina on the 11th so TEP is certainly a possibility.

In the evening time, there was a weak Sporadic-E opening to Spain and Portugal which lasted until 22:00 UTC.

144 MHz Trans-Atlantic record extended to almost 4,760kms!

The incredible tropo conditions between Cape Verde Islands and the Caribbean continue to amaze with trans-Atlantic contacts on 144 MHz and 432 MHz being made.

On Wednesday the 8th of April 2020, D4VHF in the Cape Verde Islands managed to work PJ2BR on Curacao on 144 MHz using the FT8 digital mode.

The distance was approximately 4,759 kms which is roughly 300 kms further than the previous trans-Atlantic record of 4,460 kms between D41CV and NP4BM on Puerto Rico in June of 2019.

The new 2m trans-Atlantic record distance was just 10 kms or so short of the IARU Region-1 144 MHz tropo record of 4,769 kms.

The map below shows the limit of the current IARU Region-1 record...

Update: Friday 10th April 2020 - It looks like conditions on the trans-Atlantic path improved to the point where a SSB contact was possible. While you watch the video below, remember that the distance is over 4,700kms. The distance across the North Atlantic from Newfoundland to Ireland is 3,000kms.

Quiet day on 28 MHz - Wed 8th Apr 2020

Wednesday 8th April 2020. This was a quiet day on 28 MHz with just four stations heard on FT for the whole day.

095215 -14 -0.1  959 ~  CQ PA9CC JO32
102430 -15 -0.2 2009 ~  CQ DJ5JD JO33
121145 -20 -0.3 1165 ~  CQ EA5AD IM87
153530 -12 -0.2  622 ~  CQ PD2WL JO22

The Geomagnetic Kp index was at 2-3 for most of the day which isn't good for Sporadic-E. Some of the signals heard may well have been from meteor scatter as only there was only one decode from each of the stations.

Opening to Algeria and Saudi Arabia on 28 MHz - Tues 7th Apr 2020

Tuesday 7th April 2020. This was one of those days where there was hardly a murmur out of the radio on the FT8 frequency on 28 MHz yet there were still a good number of stations recorded.

Most of the 59 stations heard were probably via Sporadic-E although it's heard to be sure about HZ1SK in Saudi Arabia as that could have been multi-hop Sp-E or F2.

As we move further into April, we should start seeing more Sporadic-E openings.

List of stations heard in order of distance...

Small opening on 28 MHz - Mon 6th Apr 2020
