EI22WAW in the log


From 1st January to 31st December 2017 Irish Radio Amateurs will be on air with nine special calls – EI11WAW through to EI99WAW.  Each call will be associated with one of the counties making up the Wild Atlantic Way.  Each call will have its own distinctive QSL card depicting a highlight of the county linked to the call.

Today, I caught up with my fifth one...EI22WAW on 20m CW. There was a bit of a comedy of errors with this one. I was adjusting the morse key beforehand to try and get a smaller gap and sure enough, it jammed just before I gave a signal report! After some frantic adjusting, it got the report across ok.

The signals was quite weak but strong enough to make a contact when the European stations weren't calling.

Four more to go.

World Handball Championships in Jan 2017...TM57A, TM57D, TM57H & TM57N

The 25th World Handball Championships are being held in France from 11th to 29th January 2017 and there are four special event stations on the air ...TM57A, TM57D, TM57H and TM57N.



Today, I worked the 4th station on CW.

16/01/2017 ...TM57H ...3.5 MHz ... CW
18/01/2017 ...TM57A ...7 MHz ... CW
22/01/2017 ...TM57N ...7 MHz ... CW
24/01/2017 ...TM57D ...3.5 MHz ... CW

The four callsigns H A N D spell HAND and as you can see from the image above, the four QSL cards when assembled show a ball in the centre....i.e. Handball.

From the organisers website....
The 25th Handball World Championship will be held in France from 11th to 29th January.
The city of Metz, will receive in its Arena the teams of Spain, Slovenia, Macedonia, Iceland and Tunisia. AMRA was keen to participate in its own way at this event, so the codes TM57H - TM57A - TM57N and TM57D were allocated for the period from 15 to 29/01. The four codes thus forming HAND, a special QSL will be edited for each of these indicative and the four QSL will form a puzzle as below. We look forward to your participation.


The QSL manager is Marc F-11734 and they will QSL via the bureau. See QRZ.COM

Presentation by John EI7IG at the TAPR Digital Conference in the USA

In 2016, John Ronan EI7IG traveled to the ARRL-TAPR Digital Communication Conference in the US where he gave a presentation on using APRS (Amateur Packet Reporting System) to track vehicles and bikes on the Sean Kelly cycle event.

The video of the talk was put up on YouTube in the last week by Gary Pearce, KN4AQ as part of his Ham Radio Now video series.



In the talk, John outlines some of the technical issues and difficulties in covering this large cycle event and making sure that the emergency services can be deployed where they are needed.

Rough guide to activity levels for the Wild Atlantic Way callsigns


The Wild Atlantic Way award has been running since the 1st of January 2017 and already, a number of overseas stations have worked all 9 calls.

If we make the assumption that the more active a station is then the more views they will get on their QRZ.COM page, this is a rough breakdown of the activity levels of the WAW calls so far.

Results of the 2017 IRTS 80m Counties Contest on New Year's Day


The annual IRTS 80 metre contest was held on the 1st of January 2017 and the full results are now available HERE

The chart above shows how the number of entries have changed over the years. While they are down on the initial years, they have  increased since 2014. It's good to see that the entries for the SSB/CW section have reached an all time high and now make up roughly half of all entries.

Slim Jim Vertical Half-Wave for 27 MHz & 28 MHz

Another one from an old magazine article. This design is for a basic folded half-wave vertical for the 11m CB band on 27MHz but it can also be adapted very easily for 28Mhz or 29Mhz. For 10m operation, try reducing the half wave section to 5.10 metres and the quarter wave section to 2.53 metres.



It really is a case of experimenting and see how you get on. It's likely the biggest challenge will be the mechanical construction rather than adjusting the VSWR.

One particular advantage of this antenna is that the quarter wave tuning section effectively puts the radiating element higher above ground level. This fact alone can have a significant effect on the performance of the antenna as it begins to get clear of buildings, electricity wires and other clutter near ground level.

A lot of novice CBer's get fixated on 'advertised gain' and different types of antennas whereas they should be concentrating on getting a decent antenna up as high as possible.

While the Slim Jim won't be as good as say a Yagi beam up on a tower, it should still perform pretty well.

Ideas for radio clubs...

It's pretty obvious that a lot of radio clubs in Ireland and in the UK have a declining membership and many are not attractive to newcomers.

One of the more active areas in the UK is in Essex and the Essex Ham website has plenty of ideas and tips on how to make clubs more attractive and relevant.

One of these is to have a skills night where there is something for everyone...newbie and experienced alike.

http://www.essexham.co.uk/skillsformula

It obviously may not work for all clubs but there is plenty of info on that site that clubs might find useful.

Old IRTS Newsletters now available...

The Irish Radio Transmitters Society is the national body representing radio amateurs in Ireland and they produce several newsletters for members throughout the year. While the newsletter isn't in the same league as say Radcom or QST, it is in many ways more relevant locally as it relates to Irish issues.

The IRTS have now put up an archive of old newsletters from 1988 to 2000 on their website.


Just go to their website... http://www.irts.ie/ ... and look for the Publications Library.

Members of the IRTS also have access to all the IRTS newsletters from 2001 to the most current one as well. Taken together, the newsletters represent almost 30 years of the history of amateur radio in Ireland from the late 1980's.

The quality of the IRTS newsletter has changed greatly over the years. Before the late 80's, it was little more than some copies of typed text. With the advent of proper desk top publishing software, it improved hugely in the 90's before colour was finally introduced in mid 2008.

As of the end of 2016, some 27% of IRTS members opt for the PDF version which is available from the IRTS website. This does of course mean that fewer physical copies must be printed and posted out which results in a saving for the Society.

For me, I just prefer the digital version as it means I don't have a physical copy that I need to store or dispose of. I can also zoom in on diagrams and photos on the PDF document allowing me to see things in more detail, something which is of course impossible in the printed version.

I just upload the PDF version to my own private online Google Drive account where they are all available for easy access. This is a screenshot from that site...


Looking at the annual financial statements for the IRTS, roughly half of the Society's annual expenditure is spent on the publishing and posting of the newsletters to members. In an age of high speed broadband and smart phones, perhaps more IRTS members should consider opting for the electronic PDF version?

It seems to me an obvious way to help the IRTS to reduce its costs and help maintain the current membership fee.

Good tropo conditions on 2m & 70cms...Wed 28th Dec 2016


The current high pressure system over the country resulted in some fine conditions on the VHF bands on Wed 28th December 2016. The local Cork repeater on 145.750 MHz seemed to be active with stations for most of the day while a few more distant repeaters were heard as well.

The opening seemed to favour the sea paths and the most consistent repeater all day was GB3WR at about 400kms. I heard this back in November but it was probably stronger this time around with a max signal of about 5/2 on my attic antenna.

A new one for me was hearing the F1ZEE repeater in Brittany also on 145.600 MHz. This has a very distinctive 'di dah dit' sound between overs with the 'dah' at a higher audio frequency compared to the two 'dits'.

The distance was 518kms which is the furthest 2m signal that I have heard so far in 2016. I was suprised to have heard it at all considering the antenna is in my attic.

According to QRZ, the repeater is at 300m ASL with a very good view towards EI.


Relais R0 de l'ARACA22  145,600Mhz en emission shift -600Khz , déclenchement 1750Hz
316m ASL installé depuis 1978 sur le site de Menez Kerespez , 22810 Plougonver, c'est le premier relais installé en bretagne. Antenne 6db COMET à 8m du sol. TX et RX Motorola MC Micro , 40w à l'emission. Responsable du site : F1LHC

It is also part of a larger repeater network in Brittany covering 10m, 6m, 2m and 70cms. Info here... https://f5nlg.wordpress.com/2015/12/28/nouveau-reseau-french-repeater-network/

70cms.......There were two repeaters heard...GB3CH on 433.050MHz and GB3CM on 433.200MHz.


While GB3CH was just above the noise, GB3CM was pretty good at times and got up as high as 5/4. It was also the most consistent signal and was there for a lot of the day.

Other than listening, I had just one contact with GW0PLP in South-West Wales on 145 MHz FM. While Don had 90w into a 5/8 GP on his house, I had 50w into a Slim-Jim vertical in the attic. While we made a contact, the signals were at best 5/2 so it might be time to think about an outdoor antenna for 2017.

Irish radio amateurs gain secondary allocation at 5.3MHz



The Irish Radio Transmitters Society have just announced that Irish radio amateurs can use the WRC-15 band of 5.3515 MHz to 5.3665 MHz with immediate effect. No application is necessary and the power limit is 15 watts. This is very good news for anyone with an interest in the 60 metre band.

The following was announced by Séan, EI7CD...

ComReg has just today published an amended version of the Amateur Station Guidelines in Document ComReg 09/45R2. The main revision is that the WRC-15 band of 5351.5 to 5366.5 kHz has been released with immediate effect on a secondary basis. No application or fee is necessary for this segment. The power is 15 watts PEP (12dBW) measured at the output of the transmitter or amplifier. All modes including digimodes may be used. The WRC-15 decision was for 15 watts EIRP and this will be taken up with ComReg. The Society recommends that USB be used for voice as has been the convention on this band and as used by the primary user and that the provisional IARU band plan be used:

5351.5 - 5354.0 kHz CW, Narrow band Modes
5354.0 - 5366.0 kHz All modes USB for voice
5366.0 - 5366.5 kHz weak signal narrow band modes.

This allocation does not affect the availability of the existing channels centred on 5280, 5300, 5332, 5348, 5400 and 5405 kHz. Special authorisation is still required for these channels at an annual licence fee of €30. Lets hope for some more activity on 5 MHz to help our case for an increased allocation.

Seán EI7CD IRTS/ ComReg Liaison

Up to now, Irish amateurs had to apply to use the spot frequencies of 5.280 MHz; 5.300 MHz; 5.332 MHz; 5.348MHz; 5.400 MHz and 5.405 MHz

The relevant document can be downloaded from the Comreg website HERE


For the moment, the Irish allocation is different from our neighbours in the UK. See HERE

UK Radio Spectrum Review Shows Increased Noise on VHF Bands


Ofcom is the organisation that is responsible for radio regulation in the UK and they have just released a document for a review of the UHF spectrum from 410 to 470 MHz. While most of the report covers the UHF spectrum as expected, they do make a reference to the increase noise levels on the lower VHF bands.

In the chart below, 'Band 1' covers 55 to 68 MHz while 'VHF Low' covers 68 to 87.5 MHz.


In the past, the assumed noise floor for radios was -116dBm and the planned coverage area of a radio system was -104dBm, i.e. 12 dB over the noise floor.

What Ofcom have found is that the actual noise floor is currently 12dB higher than previously thought. As a result, the planned service signal level must now be -92dBm.

This higher noise level is likely due to a variety of sources. Just think of the extra electrical power lines, increased use of switch mode power supplies in electrical equipment and the vast multitude of computer and IT systems. Taken all together, they result in a large increase in electrical noise especially in urban areas.

What this means for amateur radio is that bands like 4 metres (70 MHz) and 6 metres (50 MHz) are likely to be much noisier than they used to be in the past. Higher VHF and UHF bands are not effected as badly. It's likely that the extra noise levels also extend down to the higher HF frequencies like 14 to 28 MHz as well.

This higher noise floor as announced by Ofcom is in contrast to what was said by Comreg, the Irish licensing authority. In response to a submission by the Irish Radio Transmitters Society, they said the following in a report published in mid-2016....

2:17 ComReg notes that no evidence was provided by the IRTS to support its assertion that the noise floor is increasing and, further, ComReg observes that its monitoring activities do not indicate a significant increase in the noise floor on the whole;

Perhaps the noise levels in the Ofcom report are based on the very large urban areas in the UK but it's hard to imagine that the noise levels haven't increased substantially in the various Irish cities and towns in the last 20 years.

Opening to the Indian Ocean on 28 MHz...Wed 14th Dec 2016


Wednesday the 24th of December was another one of those days where the 28 MHz band seemed completely dead but early in the morning, I received 3 separate transmissions on WSPR from FR1GZ on Reunion Island in the Indian Ocean.

It's almost as if the North-South path is there on a lot of days but there just aren't any stations there to exploit it.

The Solar flux is down around 72 and the K index is a 1.

Proposed changes to the 70 MHz Band in Ireland

This is the current IARU Region 1 band plan for 70 MHz band...


The Irish allocation is from 70.125 to 70.450 MHz while the British one is from 70.0 to 70.5 MHz.

What it has meant is that the UK calling frequency of 70.450 MHz is actually on the limit of the Irish band. If any EI station were to transmit there on FM then their side bands would be outside the Irish allocation.

The most recent newsletter from the Irish Radio Transmitters Society carried details on submissions that had been made to Comreg, the Irish licensing authority. While many of the submissions were declined, it was obvious that Comreg was using European Common Allocations as their guide. i.e. if the European agreements said something about the amateur radio service then that's what they were likely to implement.

As regards to the 70 MHz / 4 metre band, they are guided by footnote ECA9 in the CEPT European Table of Frequency Allocations.

This is what the International Amateur Radio Union (IARU) said about ECA9 / EU9...

The 70MHz band is increasingly recognised as being appropriate for amateur allocations. In the CEPT area this progress is now recognised in the European Table of Frequency Allocations by Footnote EU9 which states:
EU9: CEPT administrations may authorise all or parts of the band 69.9-70.5 MHz to the amateur
service on a secondary basis. In addition it is worth noting that there is some experimental access on a national basis in the range 69.90 - 70.0MHz in cases where 70MHz is not available.

In response to the IRTS proposal, Comreg said the following about 70 MHz...

"Comreg's work plan for radio amateur services is to make available the following bands:
. the 30-49 MHz and the 54 - 69.9 MHz and 69.9 - 70.125 bands to facilitate propagation beacons, digital amateur television repeaters and to align current allocations with those in the European Common Allocation Table: and 
. the 70.45 - 7-.50 MHz band to align it with the European Common Allocation Table.

So it looks as if they will be extending the Irish allocation so that it will cover 69.900 to 70.500 MHz. This is likely to be implemented soon...perhaps early 2017???

This is how the new Irish allocation will look now compared to other countries...


As can be seen, Irish stations will now be able to work other countries simplex without having to resort to split frequency operation.

Overall, a very positive result!

Opening on 28 MHz...Sun 11th Dec 2016

With the ARRL 10 metre contest on this weekend, there was always going to be a chance that something would pop up. Even if there was a weak opening, there was a chance that contest stations running kilowatts of power might make it though.

I could see one of the big English stations spotted on the cluster and I could hear them weakly in the noise on SSB, probably as a result of some meteor scatter.

Around midday, I heard a weak cw contest station... GW5B or so I thought. Checked the cluster but no sign of that one. But ZW5B was spotted on that frequency and sure enough when I listened more carefully, that's what it was...ZW5B in Brazil! ...F2 propagation on 10m.

Within 20 minutes, more signals popped up on the band and some were pretty strong...up to s'7' at times. The following were worked on cw with 50 watts into the vertical...EA8AH & EA8CN in the Canary Islands and FY5KE in French Guyana. All of these were probably via F2 propagation. It seemed to be a pretty short opening...maybe an hour or two with the occasional strong signals for about 30 minutes.

Also heard were EA7ATX on SSB and the German beacon DL0IGI...both probably Sp-E.

I left the rig then on WSPR and heard the following weak signals via Sporadic-E during the afternoon on 28 MHz...


What was unusual was that I seemed to be hearing a lot more than the stations in England. Like yesterday, it was the fact that I was a lot further to the west than them which allowed me to hear the European stations shown above.

What I have also noticed about WSPR is that there are a lack of stations on 28 MHz. For example, today there were 4 from Spain, 3 from France, 3 from Italy and none from Poland. These are major European countries and very few were active. I was the only person in Ireland. Yet if you check say 14 MHz, there are plenty of stations there but it is questionable if a lot of those reports are of any real value to anyone.
