Opening to Africa on 28 MHz - Sun 17th March 2019

There couldn't have been a greater contrast in conditions over the last two days on 28 MHz. Saturday the 16th was practically dead while there was a nice opening on Sunday the 17th.

Saturday 16th March 2019... Just one signal heard all day on FT8 on 28 MHz. I scanned around a few times as well...nothing.
124900 -11 -0.1 1942 ~  CQ DJ5JD JO33

Sunday 17th March 2019... Nice Sporadic-E opening to Europe and it probably allowed some signals from Africa to reach this far north.


Note that this map is off the PSK Reporter website. It seems as if it only shows stations that I heard calling CQ where as I actually heard more while they were making contacts. I have shown these as Pink dots above.

This is a breakdown of the stations I heard on FT8 on 28 MHz...

OZ7IGY 40 MHz beacon off air for foreseeable future

On the 1st of January 2019, it was announced that the OZ7IGY beacon on 40.071 MHz was off air while it was awaiting a renewal of its licence.

On the 15th of March 2019, it was announced that the beacon was going to remain off for the foreseeable future.

From the OZ7IGY website.....
"40 MHz operation suspended – 2019-03-15. The operation has been suspended due to operating and licensing costs. The future of the beacon is unknown at least for the time being....OZ2M."

This is significant as it was actually the only beacon in the world that was operational on the 40 MHz band.

With the Sporadic-E season only weeks away and the increasing interest in the band, it would have been great to have something on the band for propagation tests.

Signals heard on 28 MHz - 11th to 15th March 2019

Not exactly an exciting few days but a good reminder that just listening to FT8 signals doesn't show what is really happening on the band.

Mon 11th March... Listened most of the day to the FT8 frequency of 28.074 MHz and heard nothing!

Tues 12th March..... At least there were a few signals on Tuesday.
110830 -11 -0.4  943 ~  CQ G0OYQ IO93
113730 -12 -0.1 1001 ~  CQ ON8DM JO10
145730 -21 -0.6 1820 ~  CQ G4HZW IO83

Wed 13th March... Pretty similar to yesterday with the usual suspects being heard.
124615 -10 -0.0  583 ~  DJ8QX PD1DL RR73
125930 -16 -0.1  582 ~  CQ PD1DL JO22
132200 -17 -0.2 1143 ~  CQ DJ8QX JO31

Thurs 14th March... Just the two regulars on the band.
105630  -3 -0.3  955 ~  CQ G0OYQ IO93
133430 -16 -0.4  875 ~  CQ DJ8QX JO31

Fri 15th March... This was probably the most interesting of the five days. Most days, I just leave the radio on the FT8 frequency and decode any signals heard. The one obvious problem with this is that I have noticed that there is an obvious lack of stations using the band and whenever I hear someone, it tends to be the same person.


FT8 decodes on the 15th...
151315  -7 -0.6 1687 ~  CQ DL2RH JO32
153730   7 -0.4 1318 ~  CQ DJ8QX JO31
171645  13 -0.2 1136 ~  CQ EB1HRW IN71
184715  -1  0.0 1283 ~  CQ EA1GAR IN52

For a change today, I decided to have a listen around the band. Looking at the DX cluster, DX Maps and the PSK reporter websites, it looked as if nothing was happening on the band.

Example of Italian CB signals heard at 43 MHz...



The video clip above shows an example of a signal heard on the south-east coast of England of  a 43.3 MHz signal from Italy.

The CB band at 43 MHz in Italy is more of a 'working band' as opposed to the hobbyist nature of the band at say 27 MHz.

There is a short discussion about Italian 43 MHz radio on this forum.

It would also seem that the band is used is used to relay church services in Italy to elderly members of the public at home. Video of 43.575 MHz signal below. In Ireland, this is usually done on the 27 MHz CB band although some churches have been known to use 88-108 MHz!

Club Log stats show the rise of FT8 mode in 2018


A huge number of radio amateurs upload their logs to the Club Log site every year. In 2018, a total of 41.3 million QSOs were uploaded (2017 = 36.8 million, 2016 = 36.8 million, 2015 = 39.8 million).

With so many contacts being uploaded, it's a good place to show recent trends.

The chart for 2018 shown above shows the popularity of each respective mode during normal operating times outside of contests. (Note that the data from the major contests is excluded so as to not distort the data).

A few things jump out from the chart...

1) The sheer popularity of the FT8 digital mode.

2) The decline in phone / SSB contacts.

3) Morse / CW seems to have declined as well but fares better than SSB.

4) The decline in all other modes like PSK31, RTTY, etc.

A lot of people complain about FT8 and its 'impersonal nature' but the stats show what people are interested in using.

Full info up on G7VJR's blog.

Italian 43 MHz CB's for sale...


One of the obvious problems with the new 8 metre band at 40 MHz is the lack of equipment. I recently came across an Italian website selling 43 MHz radios. As outlined in a previous post, there is a CB band in Italy on 43 MHz.

The HardSoft Products website is selling the following at present...

1) INTEK - SY-5430M - MOBILE 43 MHz
...a) The Italian version has 24 channels with a 4 watt output. It covers 43.3 MHz to 43.5875 MHz. The cost is €185.

...b) The Export version has 224 channels with a 20 watt output. It covers 42.3 MHz to 45.0875 MHz. The cost is €210.

2) LAFAYETTE - MOBILE UTILITY 43 MHz 24 CHANNELS
This has 24 channels with a 4 watt output. It covers 43.3 MHz to 43.5875 MHz. The cost is €145.

Please note that these were the prices and models as of mid-March 2019. I don't know anything about the website so I can't say if it's ok or not.

FT8 signals heard on 28 MHz - Sat 9th & Sun 10th March 2019

Another quiet weekend on 28 MHz with the highlight being one South American station being heard.

Sat 9th March 2019... Just a few signals from the UK and Germany heard.


073430  -6 -0.3 1052 ~  CQ G0OYQ IO93
081100 -16  0.1  789 ~  CQ DO3MA JO40

Opening to Sierra Leone on 28 MHz after quiet week - Sat 2nd to Fri 8th March 2019

I have been monitoring the FT8 frequency on 28 MHz for the last week and things have been pretty quiet. The best day of the last week was Friday the 8th of March when there was an opening to West Africa.

This is a breakdown of the last seven days...


Saturday 2nd March 2019... Just two stations heard all day.
135445 -13  0.7 1690 ~  CQ PA8MC JO20
164015 -11 -0.1  596 ~  PD1KD PD1DL RR73

IRTS Membership - 2000 to 2018


The Irish Radio Transmitters Society (IRTS) is the national association representing amateur radio in Ireland.

They have just released their membership stats for the end of 2018 and it stands at 919 members, a drop of 8. To put that in context, that's a drop of 0.9% so it's pretty much negligible.

That figure of 919 includes overseas members and short wave listeners so the actual number of EI stations that are members is probably around the 770-780 mark, about the same as last year.

Thanks to the new GDPR regulations introduced in 2018, the data on the total number of radio amateurs in Ireland is not available. However, it is probably much the same as last year.

At the end of 2017, roughly 45% of all EI stations were members of the IRTS. Contrast that to the ARRL in the USA where the figure is below 20%!

IRTS release Spring 2019 issue of Echo Ireland


The Irish Radio Transmitters Society (IRTS) have just released PDF version of the Spring 2019 edition of Echo Ireland to members.

The electronic version is sent out to members before the printed copy and is of course much cheaper to distribute. These savings help to keep the Society in the Black as costs are increasing all the time.

Details of the PDF option below...

DMR repeaters in Ireland - March 2019

These are the DMR repeaters in Ireland at present. Some are on air, some are planned.


The full listing of all DMR repeaters can be seen here... http://ham-digital.org/dmr-rptrreg.php

New Digital repeaters near Dublin on the way

Update March 2019 : It looks as if there are two new repeaters on the way.

EI7BCR will be located at Three Rock in the Dublin Mountains and will have DMR ID of 272222. This should give excellent coverage of the capital city and will be a great addition to the digital network in Ireland.

The proposed output frequency is 439.7875 MHz and the input is 9.0 MHz lower.

The second repeater EI7LLD is located near Kingscourt, Co.Cavan. This will have DMR ID 272223. This should give good coverage of Dundalk and the area to the north-west of Dublin.

The proposed output frequency is 439.7625 MHz and the input is 9.0 MHz lower.

This was first announced back in November 2018 and there is no sign of them to date.

RSGB Paper suggests additional access to 40 MHz unlikely in the UK



The IARU Region 1 (Africa, Europe, Middle-East) Interim Meeting takes place April 27-28 in Vienna, Austria.

An Information Paper submitted by the RSGB seems to suggest additional access to 40 MHz is unlikely in the UK. See below... 

Document number: VIE19 C5 INFO1 
Source: RSGB – Murray Niman G6JYB, Spectrum Chair 
Subject: Innovation Bands & Activities (Information Paper) Committee(s): 
C5 Summary: The Information below is a short summary regarding the additional spectrum available to UK Full Licensees and how it is used. 

In general:- 
• All require a strong justification, conditions to avoid interference and have a Strong Emphasis on Innovation & New Activities – not ‘More of the Same’ 
• They are renewable permits - not permanent allocations 
• Renewal is based on regular progress reports to our regulator against the purpose it was made available for Previous Bands/Requests:- 
40 MHz – One Propagation Beacon – additional access refused

When will the next sunspot cycle start???

At the moment, we are very much at the bottom of Solar Cycle with no sunspots being reported on the sun for the whole of February 2019.

The obvious question is when will the next solar cycle start? When will conditions improve?

Some think conditions will improve in 2019 but my own take on this is why the rush? In terms of a solar cycle, we have only just got to the minimum and we will probably hop along the bottom for a while before things pick up.

As with all things associated with the sun, we can only make calculated guesses based on past observations.

Say we take an arbitrary figure of an average of 25 sunspots on the sun. This point is measured on the way down to the minimum and on the way back out again.

Looking at the chart below, the sunspot number was below 25 for roughly three years between solar cycles 22 and 23.


The next minimum between solar cycles 23 and 24 was deeper however and lasted longer. It was below the 25 sunspot mark for about five years.

If and that is a big IF this current minimum is deep like the last one and is below the 25 sunspot mark for five years then we get a chart like this.



This suggests that conditions for the rest of of 2019 will remain poor. It also suggests that it will be the second half of 2020 before the number of sunspots and conditions start to pick up. It will be mid-2021 before the sunspot numbers hit 25.

A sunspot number of 25 seems to roughly correlate with a solar flux of about 80 which isn't exactly huge. It should result in some more North-South openings on 28 MHz as well of course much better conditions on the lower bands.

Things after that however will only get better and it's anyone's guess as to how high the next peak will be.

In conclusion, if the next solar cycle behaves like the previous one then it was be mid-2021 before we see any dramatic improvement.

Early 6m DXing in Ireland article reprinted in club newsletter in the USA



A few weeks back, a club in the USA made contact with me about republishing one of the articles on my old website about the 50 MHz band in Ireland from 1957 to 1980.

The article is now in the March 2019 issue of the club newsletter.

Opening to South Africa on 28 MHz - Fri 1st March 2019

After a dismal three weeks, the 10-metre band finally opened up to South Africa on the 1st of March.


These were the stations heard...
110100 -13 -0.6 1264 ~  CQ DJ8QX JO31
114415   1  0.1  899 ~  CQ ZS5PD KF59
114615 -15 -0.2  441 ~  CQ EA5AMC IM98
120715 -16 -0.1  664 ~  CQ G7ODN IO92
123545 -17 -1.2  942 ~  CQ G0OYQ IO93

Some points of interest...

1) South Africa... There seems to have been a Sporadic-E cloud over the Bay of Biscay allowing me to hear an EA5 station near Valencia. This then coupled into some F2 propagation to South Africa.

2) Low Activity... The map on the right above shows who heard ZS5PD on 28 MHz. PSK Reporter shows only four stations hearing him which suggests a distinct lack of stations monitoring on 28 MHz.

3) Sporadic-E Propagation... I noticed from G3XBM's blog that he was hearing an EA7 station near Gibraltar about the same time I was hearing an EA5 near Valencia. We were both probably getting signals from the same Sporadic-E cloud over the Bay of Biscay.

It's likely that I was just in the right location as the path to EA5 lined up with South Africa. For G3XBM 500kms or so to the east, the extended path beyond EA7 probably was just down into the South Atlantic.

Slim pickings but hopefully things might pick up as the equinox approaches.

FT8 signals heard on 28 MHz - 23rd to 28th February 2019

I have been listening on 28 MHz for the last few days on the FT8 and the pickings have been slim. Just a few signals were heard most days with no sign of anything from outside Europe.

The last time I heard a signal from outside Europe was back on the 8th of February when I heard Paraguay. February has been easily the worst month of the 2018/2019 winter season in terms of 10 metre propagation. Easily known we are at the bottom of the sunspot cycle!

Perhaps as we get closer to the equinox, things will pick up? At least we're only 6-8 weeks away from the start of the Summer Sporadic-E season.

This is what was heard over the last few days.

Sat 23rd Feb... Three signals!

IRTS paper on the new 5 and 8 metre bands to be presented at IARU Meeting


The IARU Region 1 (Africa, Europe, Middle-East) Interim Meeting takes place April 27-28 in Vienna, Austria.

Among the many things discussed, there will be a paper from the Irish Radio Transmitters Society on the new proposed bands at 40 MHz and 60 MHz.

Link... https://vienna.iaru-r1.org/wp-content/uploads/2019/01/VIE19-C5-002-IRTS-40-and-60-MHz-bandplans.pdf

There probably isn't a whole lot new in it that hasn't been seen before but it does present the information to other member societies. If the new band plans are formally adopted then other countries may start looking for allocations of their own.

Extract from the document..."Next Steps : Tables 1 and 2 below are suggested band plans for most of the 5 and 8 metre spectrum granted to the amateur service in Ireland by ComReg. The plans are loosely based on the current 50–54 MHz IARU band plan and have been in the public domain since May 2018 by means of the IRTS web-site.

Concerning propagation beacons work has begun on upgrading some existing beacons and procuring beacons in the new bands. Transverters are already on the market to transvert 40-42 MHz to 28-30 MHz. Originally intended for the Italian 4 Watt “Apparati a 43 MHz” service in the 43.3000 – 43.5875 MHz band, an “international” version is freely available in the Ukraine. This 25 Watt FM transceiver for the band 42.3000 – 45.0875 MHz has a 224 channel capability and is manufactured in Korea and the Philippines.

Amateurs in the Dublin area are currently trialling both the 40 MHz transverter and
the 42 MHz FM transceiver."

Other VHF related papers to be presented at the meeting can be seen here...

Listening to OSCAR 100


The new Geostationary satellite OSCAR 100 is now up and running and the narrow band down-link can be heard online here... https://eshail.batc.org.uk/nb/

The up-link is at 2.4 GHz and the down-link is at 10 GHz.

Anytime I've listened during the last week, there has been a small number of signals on the down-link. There has been a lot of hype about this particular project although I'd wonder about how popular will it be?

The coverage footprint is shown below...
