Sorting out those QSL cards...

Things have been pretty quiet here on the radio front. The spring gales took their toll and my HF doublet is down at present although it won't take much to get it going again. Otherwise, I have been sorting out my QSL cards. I tried before to sort them out by band but it was just way too awkward. So, I have sorted them out now by country and they're all now neatly filed away. Once thing that became apparent however is the number of German QSL cards. Germany has a large amateur radio population and the distance from Ireland to Germany is almost optimum for Sporadic-E contacts on 10m, 6m and 2m....hence the large number of cards.

I'm not exactly sure how many are in there but there is a 1 Euro coin at the bottom for scale.

I think it's safe to say that I have Germany confirmed by QSL at this stage ;o)

Saker Falcon missing...IRTS News

Just came accross this on the IRTS news.......
Missing Saker Falcon. A request has been made by a member of the Public, to try to find a missing Saker Falcon. The Saker Falcon recently went missing in the Dublin area of Inchicore / Ballyfermot. It has been suggested that if anyone can monitor 216.10MHz FM to try to pick up her signal, which is a constant beep to contact Gerard at 086 3640975
What's strange about this......other than the fact it's about a missing bird.....is that 216.1 MHz is right in the middle of Band III TV in Ireland.
A little more digging suggests that the collar may have come from the USA where that frequency seems to be used for tracking.
Channel I on Band III is at 215.25 Mhz. Now it just so happens that Network 2 is broadcast from Mt.Leinster on Ch I. So, considering that 216.1 MHz is right in with the video signals and if this bird heads for the mountains, this tracking collar (probably milliwatts) is going 'head to head' with a transmitter with an ERP of 230 Kilowatts!!

The best chance of hearing that bird is probably if it lands on someone's TV aerial and causes TVI ;o)

Special Event Station...EI100CQD

I came accross this video clip on the net. EI100CQD was a special event station that was operational over the weekend of the 23rd to 25th of January 2009. I heard them mentioned on the IRTS news but the station didn't seem to be operational on 80 metres so it was very difficult for any EI stations to hear them.


The video clip shows Tony, EI5EM operating the station EI100CQD and having a contact with Jarda, OK5JM in the Czech Republic.

mmmm......a 3 el yagi for 160m

With no antenna for 160m, I had to give the CQWW 160m CW contest a miss last weekend. However, I came accross this gem on the net..........OH8X and their 3 element yagi for 1.8 MHz.

Not only are they using a 3 element on 160m but they have a 5 element yagi for 80 metres above it!!
All of this on a 100 metre high tower....

.........and my favourite....
.......a rail inside the boom for walking on!......at 100 metres above ground level!.........any volunteers??

Up and Running on Logbook of The World

Quick recap.......
1) I had updated my VQLog program so that it now contains just over 23,000 contacts. From this, I could generate an ADIF file that Logbook of The World could use.
2) In mid January, I had tried to use to use the LoTW software but I had problems with passwords at the final step when I was trying to 'sign' the ADIF file and generate a TQ8 file for upload.
3) I looked on the LoTW website but could see no obvious answer. So, I sent the ARRL an e-mail with my private e-mail account (gofree) asking for advice.
Current.......
1) After 2 weeks I had no reply to my e-mail. Someone else had also said that they had not received a mail I sent with my private e-mail account. So, I resent the mail to the ARRL on Fri 23rd Jan using my Yahoo mail account.
2) Within 2 hours, I had a reply! The advice was...
Delete any and all TQ5, TQ6 and TQ8 files in your folders.
Open TQSL CERT
Delete any lines with a callsign.
Select FILE > NEW CERT REQUEST
Request a new UNSIGNED certificate for your call EI7GL. Do not use an end date and do not use a password.
Upload the resulting TQ5 to LoTW. Disregard any messages about overlapping certificates or dates.
Stand by for your TQ6.
3) So, I deleted the TQ5 and TQ6 files that had been generated. Ran TQSL CERT again, generated a new TQ5 file (with no password this time!) and uploaded this to the LoTW website. As I had been approved already, I assumed that I would have a reply in a few days.
4) Within a few hours, I had received the TQ6 file back from the ARRL!! I ran this, unlocked my certificate and then proceeded to sign my ADIF file.
5) This time, it went past the stage where I had got stuck before with the password and it began the slow process of generating a TQ8 file from the 23,000+ qsos in the ADIF file.
6) I got a lot of errors, especially with all of the Satellite contacts that I had. It didn't seem to like the format that VQLog was using for Satellite qsos. In fact, as far as I can see, it rejected all of them. Besides the Satellite contacts, it rejected 2 other contacts.....
EA1DDU.....due to "Invalid PROP_MODE (TRD)". VQLog gives the choice of 'Tropo ducting' as a propogation mode. It seems as if LoTW doesn't accept it. It seems strange as on the FAQ on the LoTW website, it make no mention of needing propogation modes.
GD0PLT.....due to "Invalid amateur CALL (GDOPLT)". My first thought was that I had entered the letter 'O' instead of the number zero in the callsign. But no, I had it correct. I have no idea why it was rejected.
7) Eventually the process was completed and I ended up with the required TQ8 file. I logged on to the LoTW website and uploaded the TQ8 file. At first, I got a message saying that it was pending but pretty soon as I was refreshing the page, I could see that the number of qsos were increasing as well as the matches.
8) I left it for a while and after 30 minutes, I had 22,449 uploaded contacts and 1,945 matches. That is about 8.7% . Compared to the QSL rates that others are getting (15-20%), 8.7% might seem a bit low. I would assume that because my contacts are over a span of 20 years, many of the older contacts will never appear on LoTW because the person in question may have gone off the air. The oldest match was for a contact on the 3rd Oct 1986! The newest was for the 13th Jan 2009.
9) So, a quick look at the matches.
These are the number of DXCC countries that LoTW found a match for on each band. Note that this is via LoTW only. There are no physical qsl cards / previous credits in there.
Looking through the LoTW matches and comparing them to my log, I now have these extra countries confirmed....
Band....../...........Countries
6m......1 new country confirmed (PJ7)
10m....3 new countries confirmed (3X, A6 and ZL)
12m....7 new countries confirmed (HL, J6, KG4, KL7, PZ, ST and XZ)
15m....12 new countries confirmed (EY,FP, GI, HK, J7, KL7, PJ2, ST, VP2E, ZC4, ZD8 and ZL)
17m....10 new countries confirmed ( 3B8, 4U1ITU, C31, EA8, PZ, ST, VK9N, VP2M, XZ and ZF)
20m....1 new country confirmed (YV)
30m....6 new countries confirmed (KL7, OY, ST, TF, XZ and ZD8)
40m....3 new countries confirmed (A6, D4 and V4)
80m....1 new country confirmed (D4)
160m..6 new countries confirmed (CT3, GD, GM, GW, LY and OE)

So, in total, that makes 50 'band' countries that I do not have to get physical qsl cards for.
Out of those, I now have 5 DXCC countries which are only confirmed by LoTW on any band (PZ, ST, XZ, J7 and VK9N)...i.e. I do not have physical QSL cards for them.

After messing about with the LoTW website for a while, I eventually found the page to link the LoTW credits with my existing credits. Again, I thought I would have to wait a few days for someone to process this request but it was done within about 1 hour.

My combined record now looks like this....
I have applied for DXCC on 40m, 10m and 6m before so the overall numbers are high for these bands. For example, what the above chart is saying for let's say 10 metres is that my current DXCC credit is 113, I have another 31 credits from LoTW and when I enable them, I will have a total of 144 DXCC on that band. This of course, does not take into account any physical qsl cards that I may have here for additional countries. For bands where I do not have DXCC, like say 20 metres, LoTW brings my DXCC credit from 14 up to 83. So, if I was to apply for a 20 metres DXCC today (100 DXCC minimum required), I would only have to submit 17 extra QSL cards rather than 86.

Overall Conclusion....By using LoTW, I have got 50 new band countries confirmed and it has reduced the need for me to submit physical QSL cards for future DXCC awards. Overall, it was well worth doing and in my opinion, it really is vital that anyone who has a serious interest in the ARRL DXCC award programme should get going on Logbook of The World as soon as possible.

Short Wave Listener QSL cards...

Having recently gone through a backlog of incoming QSL cards, I had the usual few SWL (Short Wave Listener) cards in there as well. I came accross one for which I could find no match in the log so I left it to the end.
Got to the end, re-checked VQLog and my paper log....no sign of the station mentioned.

This is the QSL card...


........and here is the back.


Now, the card is a bit unusal. SWL's don't usually send cards for having heard 'cw' contacts. If they have spent that much time listening to and learning morse, most have gone one to get a licence and get on the air themselves.
I knew I had worked PA1SIX before but just not on that particular day.

I was curious....so I used the 'search' function on the DX-cluster.


PA1SIX 50105.0 EI7GL 559 E 1426 29 Dec


So, PA1SIX had spotted me but did not call me. Note the time, 14:26, the exact same time as what was on the qsl card. So, was this SWL just picking callsigns off the cluster and sending them qsl cards???


So I dug a bit more.......


I found this on an AMSAT forum...
Hi all , this is JH3DJX/Yuki . I received SWL card from DO2OTH . The report was the QSO via SO-50 worked with JH5DAH over Japan .How could he hear our QSO at Germany ?I send e-mail to DO2OTH , but no reply . Can anyone explain this mystery ?


Now, SO-50 is in low Earth orbit so it is impossible to hear it (70cms) in Germany when it is over Japan. Again, a quick check on the cluster suggests an answer...


JH3DJX-@ 436800.0 JH5DAH VIA SO-50 SAT (Saudisat-1C) 1211 21 Jan (2003)


There seems to be little doubt this time, DO2OTH (now DL6BT) just picked a contact off the DX-cluster and sent them a qsl card hoping that they would reply.


Q. What is the point in a SWL sending someone a QSL card for a contact they did not hear???

QSL status......19th Jan 2009

Now that VQLog is updated, I spent the last few days going through the backlog of incoming QSL cards. Out of the 200 or so cards, there were a few nice ones which confirmed a few new band countries for me. I think the one from Iraq might be the only card I have from that country. Needless to say, the vast majority were from European countries. All QSL cards have now been answered and I'll probably send them to the outgoing buro in a few weeks time.

Next step...
1) Logbook of The World. Nearly got it working but fell at the last step! I was near the end of the process and I had problems with the password that I thought I had supplied. Looks like I'll have to start again and get a new key. At least this time, it should be pretty quick.

Video clip from EI/ON5GS/P in IO55 square...


In some previous posts(here & here), I had some information about ON5GS's 144 MHz meteor scatter expedition to IO55 square in Dec 2008. I recently came accross a video clip of his on YouTube. I think the sound of the wind and the snow on the mountains say a lot about the bad weather conditions.


Irish Castles on the Air...24-25th Jan 2009

Just came accross this news item.....
Oranmore Castle activation
Members of the Galway VHF Group will be activating
Oranmore Castle from 12 mid-day on Saturday the 24th until 4 pm on Sunday the 25th of January.
Activity will be on all bands depending on conditions. The WAI locator square is M32 and the Castle number will be EI/001/C.
This will be the first activation of a castle since the launch of
CASHOTA-IRELAND. The Galway VHF Group Club callsign, EI4ALE/P, will be in operation for the duration of this event.

Men's World Handball Championship Croatia 2009

On the 2nd of January, I worked 9A2009ST thinking he was just a special event station for the new year. Today (13th Jan), I heard a few more 9A2009 stations and checked them out. They are in fact special event stations for the Men's World Handball Championships and there are 7 stations, one in each city.

A special award is available to anyone working 3, 5 or all 7 stations.

Some details....
Award is available to all amateur radio and SWL stations that in the period from 1st January until 1st February 2009 establish certain number of QSOs with special stations from 7 cities in which will be held 21st World Handball Championship for men as follows: Zagreb, Varazdin, Osijek, Porec, Pula, Zadar and Split.

All modes of operation are allowed: CW, SSB, DIGITAL, MIX.

For the award it is necessary to work just one special station in each city on any band.
Special stations from before mentioned cities will operate under following call signs:
ZAGREB – 9A2009ZG, VARAZDIN – 9A2009VZ, OSIJEK – 9A2009OS, POREÈ – 9A2009PO, PULA – 9A2009PU, ZADAR – 9A2009ZD, SPLIT – 9A2009ST

More info can be found on the this website. Judging by the pile-up they had on 80m ssb this evening, it seems to be very popular.

Checking of VQLog finished...

I started the long and arduous process of checking my logging program, VQLog against my paper logs back in mid-November 2008. Now 2 months and 23,039 qso's later, I'm finished at last!! At the beginning, it was really slow as I had to enter a lot of old contacts that I had never entered into my old Fastlog logging program. Originally, I had feared the whole process would take about 6 months but in the end, it took 'only' 2. With the exception of a small number of repeater and crossband contacts, I literally put everything into the logging program....towns, counties, Worked All Ireland squares, Worked All Britain squares, US states and so on. From the rare DX contacts to the local contacts accross town on 70 cms. Lots of data that can be used and searched.

And of course, lots of graphs! Here is a breakdown of all my contacts per band.

Some observations....
1) I found perhaps 20 mistakes where I had originally put the incorrect callsign into Fastlog. 20 out of 20,000 is only about 0.1% . Perhaps I missed a few more? but the logging program is now a lot more accurate. One typo was for R1FJL. I had entered the wrong suffix and VQLog recognised it as Russia. Corrected the call and I got one extra band country on 20m. I had entered the wrong date on several contacts....not much use if they end up getting used on Logbook of the World which looks for a date and time match.

2) When I imported all of the 20k or so contacts from Fastlog into VQLog, it did not always recognise the country correctly. An example was the prefix TO which was used in Martinique and Guadeloupe. VQLog had thought they were just French stations. Correcting these gave a few more band countries. Another more obvious one was for GB stations. These are used all over the UK. VQLog presumed that they were all in England but in a lot of cases, they were not. Lesson.....if you are importing data from one logbook into another...(or even data generated by a contest logging program)....you have to check the unusual prefixes to make sure that they are recognised properly. I'm sure that holds true for any logging program.

Next step.....
1) LoTW....I received the password from the ARRL back on the 5th of January. I now have to figure how to use this Logbook of The World. Uploading 23,000 qso's should get me a 'few' matches ;o)
2) QSL's.....I have several hundred cards that need to be checked. I had a quick look already at these and there are some nice DX ones in there. As well as updating VQLog, I will also need to reply to a lot of those cards. Hopefully, I'll be sending off a batch of qsl cards to the outgoing buro at the end of February .

E44M not in the log...

I didn't have much luck trying to work these guys in Palestine. It seemed as if most of Europe were calling them.....too many for a low horizontal antenna and 100 watts to get through on the low bands (3.5 to 18 MHz).
Here is a video clip I found. Seems as if they were getting a lot of interference from the lifts in the building they were in.....

BH7H...video clip from 1997

A few weeks back, I had a post about the 2007 Scarborough Reef expedition. I came accross a video clip about the 1997 expedition on YouTube. It really shows how small these rocks are.


Recent events...

31st Dec 2008.......Back on HF....
Spent the day repairing my old Doublet antenna. 3 years of neglect (.......and running over the feedline with the lawnmower ;o) had taken it's toll. Ran a new lenght of 300 Ohm twin lead cable from the shack to the feed point of the antenna. Replaced 2 other lenghts of cable. Left the antenna that evening at a mere 1.5 metres above ground level and even at that height, I managed to work DL7VPE/P near Berlin on 80m cw. Raised the antenna the next day so that now, it is roughly 5 metres above ground level. Still a bit low but enough for the moment so that I can use 3.5 MHz to 18 MHz. Even at this height, it seemed to work fine on 80m for the IRTS counties contest. Also worked OH0 and ZD8 on 30 metres over the last few days. Getting a bit more height on it should make a big difference.

3rd Jan 2009.....Quadrantids Meteor Shower...
I was on for this one. Plenty of pings and bursts. I must put up a seperate post about it soon.

5th Jan 2009...ARRL Logbook Of The World...
I had posted the documentation back on the 22nd of December to the ARRL. Received my password by e-mail from the ARRL on the 5th of Jan. A wait of only 2 weeks. I hope to be up and running on LOTW by the end of January :o)

6th Jan 2009...EI 6 Metre activity evening...
I had a listen around 21:00 and heard nothing. From what I hear from e-mail correspondance, it would seem that this activity evening is no longer supported. Seem's a pity.

IRTS 80 Metres Counties Contest...1st Jan 2009

This was my first time trying out this contest as I had been off the air for the first 3 (2006-2008). I repaired my HF doublet antenna on the 31st of Dec so that I would be ready for the contest on the 1st. I had no real intention in taking part in the contest as such, more just to get on and give away a few points.
My contest...
The contest started at 14:00 and lasted until 17:00.
14:00 to 15:00...I spent the first hour on CW calling CQ Test, worked 19 stations and gave away a few points.
15:00....Time for coffee!! ;o) I spent about 15 minutes listening around. Going from CW to SSB was like changing to a completely different band. On CW, there was hardly any contest activity at this stage. Just some G and European staions in qso mode. On SSB, the contest segment was hopping and all of the EI stations seemed very busy.
15:15 to 16:00....Back on CW calling CQ Test. Worked just 6 stations in 45 minutes with most of my CQ calls going unanswered. By 16:00, the CW part of the contest was well and truely over.
16:00....More coffee!! This CW is thirsty work ;o) The SSB section was still hopping at this stage. I was half thinking about calling it a day but seeing as how busy the band was, I decided to give away a few more points. Time to get the microphone out of the drawer ;o)
16:15 to 16:48...Tuned up and down the SSB part of the band giving away a few points.
16:48 to 17:00...Found a clear frequency and called CQ Contest so that anyone tuning around the band would find me. Worked about 16 stations in the last 12 minutes.

Totals......61 contacts, 25 on CW and 36 on SSB. 18 counties worked.

Overall Impression and thoughts.....
1) An excellent contest. 3 hours is just the right lenght, 80 metres is the right band and it was great to see so many EI stations on the band.
2) Good to see that the IRTS have not introduced that 'Sprint'/ 'QSY' rule like they did for the 2 metre counties contest.
3) After the first hour, the CW section of the contest was more or less over. If anyone is going to try CW, then the first hour is the time to be on that mode.
4) It seems a pity that for those in the Mixed contest, CW contacts only have the same value as SSB. If someone was going to try and win the mixed section, there would be a case for just working 2 to 3 CW contacts and then spend the rest of the contest on SSB to maximize the points. Perhaps if CW contacts had double or triple value, it might make things more interesting. i.e. Do you stay on CW with a lower qso rate but higher value points or do you try SSB with a higher qso rate but lower value points.
5) Looking at the results for the last 3 years, these were the entries...
Section......2006........2007.........2008
SSB............29..............45.............47
Mixed........11...............20............7
It will be interesting to see what the entries for 2009 will be like. Listening to the serial numbers given in the contest, I'm guessing that the SSB numbers will be up while the Mixed entries will be low again.

So overall, a good fun event. I might try and make a serious effort at it next year.

GB3RAL on 28 MHz & the Ursids Meteor Shower

On the morning of the 22nd of Dec 2008, I had a listen for meteor bursts from the GB3RAL beacon on 28.215 MHz during the Ursids meteor shower. This shower is supposed to have a number of active 'outburts' sometimes. This year, the forecast for the peak was for 07:30 UTC.

Why GB3RAL??.........I tried listening to other beacons in Europe around the 1,200 km to 1,500 km mark. Some run very low power so the refections are very weak. In addition, this distance is very good when there is any type of Sporadic-E propogation and it can be very hard at times to tell the difference between the Sp-E and meteor scatter. At least with GB3RAL at 490 kms, Sporadic-E is somewhat less likely and reflections for meteor scatter are likely to be stronger although shorter in lenght.

Equipment : As before, Kenwood transceiver on CW with a 500 Hz filter. Antenna in use was an old CB type half wave vertical.

Listening Period.........07:00 to 10:00 UTC on the 22nd of December 2008.

Results.......Plenty of pings and bursts but there was nothing spectacular. I didn't notice any particular sharp peak in activity. At best, it could be described as 'a small' increase in what be heard normally.

For the 3 hours, the level seemed to be much the same.
Between 08:00 and 09:00 UTC, I heard 9 pings and 9 bursts (10 sec x 1, 20 sec x 3, 30 sec x 3, 60 sec x 2).
Between 09:00 and 10:00 UTC, I heard 14 pings and 9 bursts (10 sec x 3, 20 sec x 3, 30 sec x 1, 60 sec x 2).

All signals were pretty weak. Note however that it was not possible to get a positive ID of the GB3RAL beacon as it's keyer is currently faulty. However, there would seem to be nothing else that it could be other than GB3RAL as there is no other beacon listed within meteor scatter range on that frequency.

From my point of view, there did not seem to be any 'outburst' in activity. Looking at the activity level plotted on the Make More Miles on VHF website, it does not seem to show much activity either. On the chart, the Geminids show up very clearly whereas the Ursids look pretty poor.

It looks as if the 2008 Ursid meteor shower was nothing special.
The next shower is the Quadrantids. These are supposed to peak at 13:00 UTC on the 3rd of Jan 2009.

Dec 22nd....Good Tropo conditions on 144 MHz from EI

Interesting to see that even at this time of year, 144 MHz can still suprise. On the 22nd of Dec 2008, there was some nice ducting of 144 MHz signals between the North coast of Spain, the West coast of France and the UK and Ireland. While most of the signals were over a marine path, perhaps the duct was somewhat elevated because plenty of 'inland' stations were getting in on the action.
For example, the EI stations in IO52 and IO53 would have hills (~400m) between them and the South coast of EI. The fact they were working so much and the DX signals were in GI as well might suggest the duct was elevated?? I know there are times when we get marine ducting here on the South coast (IO51) to the North of Spain and the DX signals don't seem to get too far North.

No sign on the cluster of any 432 MHz activity. Lack of stations??? or propogation???

The graphic above was from the excellent Make More Miles on VHF website.

Getting ready for the ARRL's LOTW....Logbook of the World program

This post is mainly for my own benefit so that I can keep track of what I have done and what I need to do.

Logbook of the World is the system used by the ARRL in the DXCC program to get electronic confirmation of contacts/qso's. If two stations upload their logs and there is a match for callsigns, date, time (30 minute window I think) and mode then each station gets a credit. There is no need to submit a QSL card to the ARRL to verify the contact if you were applying for a DXCC award.


This has 2 big advantages as far as I can see...
1) It's another method by which you can get some of the rare countries confirmed. Having had countless direct QSL cards not replied to, getting contacts confirmed electronically has obvious attractions.
2) It should/might reduce the number of incoming QSL cards. After all, if someone else works me and needs to have EI confirmed then regular LOTW users won't need to send me a QSL card.

Current status.......22nd Dec 2008
I remember looking at LOTW before but I could not remember when. I had a folder on my PC with files created in March 2005 so it was three and half years ago!
I download the current version of the programme tqsl-111.exe (the version I had was tqsl-110.exe).
Normally, you would run this programme and complete the first step which is to run TQSLCert and create a certificate request. I obviously had done this before as I have the required file (EI7GL.tq5) already in the relevant folder on my PC.


I went to the ARRL LOTW website and uploaded the certificate request. I got the following results....

Certificate request processor result:
Started processing your New Certificate Request.
For call sign: EI7GL
For DXCC Entity: IRELAND (245)
For QSOs not before: 1986-10-03 00:00:00
For QSOs not after:
Your certificate request is accepted and awaiting further processing.
You must mail in (via postal mail) supporting documentation to complete the request.
Details about what to send and where to send it can be found at:
http://www.arrl.org/lotw/
Your certificate request processing is completed.



All non-US radio amateurs are required to send in supporting documentation to obtain a certificate. As luck would have it, buried in amongst all of the packets of QSL cards I found an old envelope with all the required photocopies (passport & EI7GL licence) and I had never posted. Next step is to post it! (Posted letter 22nd Dec 08........Received password by e-mail on 5th Jan 2009)

With the current progress of updating my logbook, I probably won't be in a position to use LOTW until April 2009 at the earliest anyway so there is no mad panic.

Beacons on 28 MHz during the Geminids meteor shower...14th Dec 2008

Back in mid November, I tried a few tests listening to the beacon GB3RAL on 28 MHz during the Leonids meteor shower. For the Geminids, I repeated some of the tests but this time, tried listening for some other beacons as well.


Equipment...
Same as the last time....Kenwood transciever on CW, 500 Hz filter. Antenna....old commercial CB type end fed half wave about 4 metres above ground level. I monitored the received audio using the Sprectrum Lab audio analyzer program.

I tried listening for 4 different beacons on 28 MHz......GB3RAL (~500 kms), LA4TEN (~1,200 kms), F5ZWE (~1,300 kms) and DL0IGI (~1,500 kms). I listened at two different times on the 14th of December.....around 01:00 for GB3RAL and LA4TEN and around 09:00 for all 4 beacons.


Listening around 01:00......
GB3RAL.....I received a few bursts from this beacon. Nothing spectacular but it seemed to be there ok. Due to the fact that it has a faulty keyer, I was not able to get a positive ID. Like before, a lot more shows up on the trace than what I could hear by ear.


LA4TEN......This beacon seemed to be very good. It seemed to be nearly always there and at times, it got strong enough so that I could hear the CW by ear and make a positive ID.


Why was the LA4TEN beacon so consistent?

1) My view in that direction is excellent with no obstructions so that may have helped.
2) Is it the fact that 1,200 kms might be a much better distance for meteor scatter. Certainly for GB3RAL at 500 kms, I would expect that more intense meteor bursts might be required (more ionization) and the bursts would be of shorter duration.
3) Perhaps certain directions are better at different times during the shower??
4) Or perhaps it was the power level? LA4TEN is supposed to have an ERP of 250 watts which is very high for a beacon.
5) Of course, there is always the chance that what I heard was actually weak Sporadic-E rather than just meteor scatter propogation. It's seems unlikely at 1am in the morning in December. Considering that the peak of the shower was around this time, it was probably meteor scatter.

Listening around 09:00....
Conditions were worse. I still got a few pings from GB3RAL. I got very little from DL0IGI and F5ZWE. However, LA4TEN seemed as busy as ever! Looking at other sites, the peak was well over at this stage. In addition, the radiant point for the showers in Gemini may have set below the horizon by that time. I wonder though if the LA4 beacon at this stage was Sporadic-E or or not???



Conclusions.......
1) I need to find out what times the radiant point is above the horizon for any future shower and what the likely peak time will be.
2) The results show that meteor scater on 28 MHz is pretty impressive. Everything heard here was with an antenna with no gain.

Next shower is the Ursids on the 22nd of December.

ARRL 10 Metre Contest...13th/14th December 2008

Considering that this is the only band I am really currently active on, I was on during the 2 days of this ARRL contest to see what would pop up. At this stage of the solar cycle, the solar flux level (~70) is way too low to support direct F2 propogation from this far North in Europe (52 deg N). However, some Winter time Sporadic-E came to the rescue and there were short weak openings to F and EA from here. It's amazing that when all that activity is concentrated on one band, every propogation path becomes obvious and is spotted on the DX-Cluster. Most of the signals were weak although one French station did peak at 599+10dB. However overall, most signals were weak and CW was really the only way of working most stations.
Some observations...
1) In total over the 2 days, I worked 7 EA stations, 3 F stations and 1 S5 station. There might have been some openings to Germany as well but either I was missing or it was too weak for me to hear. The band opened up for a while to LA as well with the beacon LA4TEN in JO28 making an appearance for a while. No LA stations were heard though. In terms of DX, V51AS was heard although very weakly.

As you see from the map, the orange areas represent was worked....all Sporadic-E and about 1,000 to 1,800 kms distance. The V51 station was probably a combination of both Sporadic-E and F2 layer propogation. Sporadic-E from here (IO51) to Spain and from there probably by F2 to V51.

2) This year, the contest coincided with the peak of the Geminids meteor shower. I heard plenty of pings from beacons over the weekend and no doubt, a good few contacts made by stations in the contest may have been due to meteor scatter whether they realised it or not!

3) On a personal level, several years off the radio didn't do much for my CW!.........Oooo........very rusty ;o)

4) After I worked the S5 station, I heard Robbie, EI2IP working him. Later that night I noticed that Robbie had put up the following spot on the DX Cluster

EI2IP-@ 28000.0 EI7GL John ur cw tone is not so clear! 1215 14 Dec

So, I turned on a 2nd reciever with no antenna attached and listened to my signal on 5 watts....

di...di...di...dah.....di...di...di...dah........sounds ok........Turned up the power to 50 watts.....

ch...ch...ch...chirp.....ch...ch...ch...chirp.......Oooooo......Not so good!! :o(


It reminded me of when back in the days when the Soviet Union existed and a lot of the stations there were using home made rigs and plenty would have a chirp on cw.

How to fix my problem??? I thought at first it might be too much RF in the shack. I know I cause interference to the loudspeakers of the PC in the shack so I thought that might have something to do with it. Perhaps RF was getting into the power supply or somewhere else.

Connected up my 20 year old home brew 100 watt dummy load and tried it...

ch...ch...ch...chirp.....mmm.....no joy. Then I looked at the power supply. It's a variable power supply going from 0V to 20V with a small analogue meter to show the o/p voltage and current. Looked a bit low.......mmm......checked it with a digital volt meter.....~11 volts!

Turned it up to 13.5 volts and tried again...

di...di...di...dah...success!!...........It turned out that I must have knocked the voltage dial at some stage and the Kenwood transciever didn't like transmitting with a low voltage supply. Not only that but my max power out now has increased from 80 watts to the full 100 watts.

All from a simple spot on the cluster!....Thanks Robbie :o)

5) .....and on a final note, I found myself listening nearly all the time on the CW part of 10 metres for the duration of the contest. I listened to the SSB section for a while, heard some weak signals but to be honest, I never felt inclined to open the drawer, take the microphone out, plug it in to the rig and call someone. I wonder if I was operating just SSB only, would I just get bored of the whole radio thing again???
