ULF Amateur Experiments

Stefan DK7FC is always experimenting at VLF and ULF. Recently he has been radiating a signal at 2.97kHz and he has detected his own signal at 9km. This is not earth mode. He is trying to get reports from much further.

Rally - Finningley

Sunday 24 JULY : FINNINGLEY ARS ANNUAL RALLY
 
The Hurst Communications Centre, Belton Road, Sandtoft, Doncaster DN8 5SX There will be a talk in station and doors open at 10.30am with admittance £3. The venue is all on one level. Car parking is free. There is a large indoor and outdoor trader's area with major traders, special interest groups and an RSGB bookstall. There will be a flea market. Hot food and drinks will be available all day. More information from Kevin, G3AAF on 0783 161 4640.

A list of rallies can be found at http://rsgb.org/main/news/rallies/.

As I have said before, I get sent these regularly and reproduce them here in good faith, but contact the organisers if travelling any distance to ensure the information is correct.

Geostationary amateur satellite

If all goes to plan we could have a new 13cm and 3cm transponding geostationary satellite in place next spring. Being fixed in position, Doppler should be no issue. I guess the date is a problem (these often slip) and getting it successfully in the right place and operational is in some doubt. With declining solar conditions, this could be just what we need. Of course, the dish can be fixed.

See https://amsat-uk.org/2016/06/24/phase-4a-geostationary-transponders/ .

I picked this up on the Southgate News page.

6m JT65 and 10m WSPR

There has been Es on both bands although HA9AL (1455km) was the last Es report on 10m WSPR. I was spotted in Italy on 6m JT65 a couple of times overnight.

Sunspots and 10m - Friday July 22nd 2016

Solar flux is 103 today and the sunspot number 49 (K=2). The forecast  for 10m F2 propagation is still "poor". The question is will it improve in the autumn? Luckily, we are still in the Es season and there have been days with quite good Es on 10m and 6m including during the night.

JT65 lead arrives

Well, I was impressed with the service from W&S this week. 2 days ago I noticed a problem with a cable and today it arrived by Royal Mail. I am now back on 6m JT65 TX. In the past I'd have fixed the offending cable, but sadly I am too feeble to attempt this.

UPDATE 2130z:   Received a spot from Northern Italy - I3VJW (1098km) - about 30 minutes ago on 6m JT65. "All systems are go" as they say. Yes W&S - thank you.

FTSE 250 - NOT amateur radio

I found this graph on the Internet. Not sure of the source and it will be removed if a problem. 

 

They say the FTSE 250 share index is a better indicator of the state of UK companies than the FTSE 100. Since BREXIT this has hardly changed at 17018.56 the last time I looked a few moments ago. Maybe the UK economy will be OK after all.

See http://www.londonstockexchange.com/exchange/prices-and-markets/stocks/indices/summary/summary-indices.html?index=MCX .

Tits - NOT amateur radio

We had a couple of young longtail tits eating on our bird table this morning. They are far more common than they used to be. We hear them a lot. They often go around in groups, especially in winter. Their call is a dead give-away.

6m and 10m WSPR

On 6m JT65 RX I have already seen several Gs and 2 stations in southern Europe by Es whereas on 10m WSPR my 500mW beacon has yet to be seen by anyone!

Sunspots and 10m - Thursday July 21st 2016

Solar flux is 112 today. Sunspot number is 56 today (K=1) but 10m F2 propagation is expected to remain "poor" today.

6m JT65 today

Before having to turn everything off because of the storm, I copied quite a few European Es stations and G stations by tropo or aircraft reflection on 6m JT65. I hope my new audio lead arrives tomorrow so I can resume TX on 6m JT65. Results on 6m JT65 are so much better than WSPR. I am sure this is just down to higher activity on JT65.

Storms force QRT

Well, having cut my lawn, it decided to rain, with hail and thunder. The worse seems to have moved east but it forced me to turn off all rigs, the PC and disconnect all antennas.

www.lightningmaps.org

UPDATE 1900z: Since the storm passed,humidity levels have really dropped and it is a lovely, sunny, pleasant evening now. I shall go back on the air tomorrow.

Cordless lawnmower - NOT amateur radio

After some delay, I have invested in a cordless lawnmower, powered by LiIon batteries. I have charged the battery pack and will try it later. If I can only cut one lawn between charges it will not matter. I know of a few people who use cordless lawnmowers and they seem very happy.

UPDATE 1645z: Well I tried it out on two lawns. At the moment it took less than 15 minutes for each lawn. Although I recharged after doing the front lawn there seemed plenty of energy left in the battery. Next time I think I'll do both on a single charge.

Early Es

Both 6m and 10m have shown early Es propagation this morning. It bodes well for the rest of the day, although so far I have only seen, and been seen in southern Europe.

Sunspots and 10m - Wed July 20th 2016

Solar flux is 105 today. Sunspot count is 58 (K=5) and the 10m F2 propagation forecast remains "poor".

JT65 lead

I heard this evening that W&S has dispatched my SignaLink to FT817 lead. I hope this fixes the TX issue. In the meantime I am still on 10m WSPR TX and 6m JT65 RX.

6m JT65 today (RX only)

Hot day - NOT amateur radio

We have had the hottest day of the year so far with a temperature of 32 deg C, so we spent some of the afternoon in the garden. We had tea outside. There was a gentle breeze.

Here are a few images in our garden. The first is our Crocosomia "Lucifer" and the second a cobweb on our birdbath. The birdbath was being well used by the wasps today. There was a sparrowhawk chasing the young swifts high above us. The last but one picture is of a goldfinch on our neighbour's TV antenna.  The frog (?) appeared when we started watering.

JT65 issue

I "think" I may have a faulty cable from my SignaLink unit to my FT817. I shall get a new one to see if this makes it better. The PC sees the SignaLink unit, I have TX enabled, and the FT817 works fine on USB so the FT817 PA is OK. In days gone by I'd have tried to fix the lead, but not these days as I am still unable to manage fine motor skills as a result of my stroke. I do not think this is a Windows 10 issue as I can hear the TX if I select the PC's own speakers.

Luckily I am still able to be on 10m WSPR with the stand alone beacon.

Knowing my luck 6m will be wide open across the Atlantic these next few days!

UPDATE 0948z: New lead ordered from W and S. Should be here later this week.

Sunspots and 10m - Tues July 19th 2016

Solar flux is 107 today and sunspot number 68 (K=1). The forecast for 10m F2 propagation continues to be "poor".

I need to sort out my JT65 issue next! I shall be on 10m WSPR in a few minutes. This is "stand alone", so will work once synced to internet time.

JT65 issue?

My shack PC did a Windows 10 update this evening. Whether this was coincidental or not I cannot tell, but neither WSJT-X or JT65-HF software now work: my FT817 refuses to go on TX. I need to check this out in the morning. It could be something tivial. I hope so. I shall look tomorrow with a clear head.

Ickworth (National Trust) - NOT amateur radio

Today, we went for a walk at the National Trust grounds at Ickworth near Bury St Edmunds. It was very hot, for a change. In the car coming home it touched 30 degrees Celsius. There were several dragon flies and damsel flies about.

Trident Vote - NOT amateur radio

This evening, the UK Parliament votes on whether or not to renew the Trident submarines which carry our "independent" nuclear deterrent.  I personally think this is a TOTAL waste of money. Most nations don't have this. Are we really any safer? Personally I'd rather spend the money (£100 billion?) on things that help us with 21st century threats such as terrorism.

What amazes me is why so many in the UK parliament think this is "a good idea". Sorry, but we are in NATO and are very very unlikely to fire nuclear weapons. In my view, Trident should be phased out as soon as possible.

Sorry if this is political, but I hate the whole idea of the UK having nuclear weapons at all. Were these ever to be used, it would be the end of civilisation. We should be setting an example for others to follow. Please don't tell me Trident is a deterrent. It certainly is no deterrence against terrorism and never has been. If we are short of money then we should spend what we have prudently.

Es

Both on 6m JT65 and 10m WSPR I am being spotted in Spain by Es early. This bodes well for the rest of the day.

Sunspots and 10m - Monday July 18th 2016

Solar flux is 112 today and the sunspot number 51 (K=1). The forecast for 10m F2 propagation remains "poor".

Local Museum Summer Fete - NOT amateur radio

Today, in the sunshine and warmth, our local museum and windmill is holding its summer fete with free entry for all. It is good the sun is shining. The windmill and museum are well worth a visit at any time. There is always so much to see and do.

See http://www.burwellmuseum.org.uk/ .

JT65 on 6m and 10m WSPR - Early Sunday

So far, no Es seen here yet on 6m JT65 but 5 UK stations (best DX report 219km with 1W ERP) have spotted me, most in the last few minutes. This is either tropo or aircraft reflection. It is early (0910z). Meanwhile 10m WSPR is very quiet with not a single spot so far. I did a full re-sync to internet time before breakfast. The PC clock is automatically readjusted every 1000 seconds, so as long as the PC works JT65 timing should be very good. The stand-alone W5OLF WSPR beacon on 10m is re-synced every day, although this is probably not necessary.y

UPDATE 1230z:  Still 6 UK spots on 6m JT65 and no Es here on 6m. I see that 4X1RF has spotted at least one G today, sadly not me. Maybe my 1W ERP (vertical) is not enough?  Just LZ1UBO (2039km) has spotted me on 10m WSPR earlier.

UPDATE 1728z:  Now been spotted by 8 different UK stations on 6m JT65 toda. Have copied Cornwall, France and Belgium on 6m JT65 RX today, but this must have been either tropo or aircraft reflection. No 6m Es today and very little on 10m WSPR - just LZ1UBO this morning.

UPDATE 1814z:  6m Es at last today!

ON4KST chat

See http://www.on4kst.com/chat/start.php . This is probably the most well used chat facility for radio amateurs on the internet. It is set up with various "rooms". People tend to use it to arrange skeds from VLF to microwaves.

Sunspots and 10m - Sunday July 17th 2016

Solar flux is 106 (respectable) and the sunspot number 47 (K=2). Yet again, the 10m F2 propagation forecast remains "poor".

10m WSPR

Odd, but no 10m WSPR Es spots here since breakfast, whereas 6m JT65 has produced quite a lot, mainly this morning. I assume there was Es on 10m and this shows a lack of activity on 10m WSPR?

Shortage of RF Engineers? - NOT amateur radio

Southgate News has a link on this subject. When I was in the RF business most RF engineers were getting older and close to retirement. There were few RF engineers coming through leading to a crisis in the near future. A shortage of RF engineers is a real issue in any nation. In my youth, RF was magic: these days it is not seen this way.

See http://www.southgatearc.org/news/2016/july/looming-rf-engineering-age-crisis.htm .

UPDATE 1512z:  In a recent look in our local shop I counted 15 train magazines, but not a single radio magazine. No, RF (radio frequency) is not the magic it once was. When there are as many radio magazines as train magazines RF will again be seen as interesting! It goes without saying that gaming and PC mags are everywhere.

WSJT-X versus JT65-HF software

On 6m JT65, I have reverted to WSJT-X v1.6 from JT65-HF. For some reason, I seem to RX more stations with WSJT-X. A few days ago I had some locals reporting a "ghost" TX signal some 700Hz HF but I have not heard again, despite asking, so I am carrying on with using WSJT-X V1.6. For those not familiar with WSJT-X V1.6 it combines JT65, JT9-1 and WSPR into one package.

For those not familiar with it, JT65 allows basic QSOs and is not that much worse than WSPR. Activity on 6m is far higher than WSPR.  Software is free.

6m JT65 and 10m WSPR

Plenty of early Es about and lots of 6m spots already.  Today could be a good day, but still to catch a transatlantic Es opening here on 6m JT65. Most 10m WSPR spots have been local.

UPDATE 1055z:   Best DX on 6m JT65 TX was a spot by SV1NZX (2421km) in the early hours of the night. On 6m RX I have spotted Ukraine on JT65.

UPDATE 1842z:  Still to see any transatlantic Es DX on 6m JT65. I keep looking, but no luck as yet on TX or RX. I am sure the chances are better than on 6m WSPR. I shall be on overnight again, ever hopeful.

Sunspots and 10m - Sat July 16th 2016

Solar flux is 101 today and the sunspot count a respectable 73 (K=2). The forecast for 10m F2 propagation remains "poor". Yet again, Es comes to the rescue on 10m and 6m.

Kazakhstan (again) on 6m JT65

UN7TW (5214km) was spotted on 6m JT65 this afternoon. This is a very long way on VHF. Although the considered view is this is multi-hop Es, I think some sort of chordal-Es is more probable.

UPDATE 1702z:  Still UN7TW as the best 6m DX.

6m JT65 spots

I get sent these notifications and reproduce them in good faith.  It is worth contacting the organisers before travelling any distance to check the data is correct.

Nice, France - NOT amateur radio

My heart goes out to the people of France who suffered another nasty terrorist attack last night. This was an act of pure evil. There is no way that those who carry out such acts will be rewarded in an after-life.

The people who are encouraged to carry out such attacks on innocent men,women and children may have genuine grievances, but acts of evil are evil. Losing ones life to carry out acts of evil cannot be rewarded.

2m UKAC Results

See http://www.rsgbcc.org/cgi-bin/vhfresults.pl?Contest=144MHz%20UKAC&year=2016 .

It was gratifying to see I am more than half way up the AL section at 73rd out of 162, despite just using 5W, a small omni-antenna and only being active for about 40% of the time because of my poor voice. There are multipliers I know I could have worked, but did not. As you can tell, I only enter a few contests a year and go on the air because of the activity, not to seriously enter contests. I am definitely a "fair weather" contester. I am the same with my bird watching!

Re-sync

6m JT65 spots in last 12hrs (1W ERP)

At about 0655z I re-synced my PC to internet time. I also rebooted and re-synced my 10m WSPR beacon. So, I should be perfectly set up both on 10m WSPR and 6m JT65 for the rest of the day. It could be a while before my 10m WSPR beacon settles: this can take up to 20 minutes.

UPDATE 1000z:  So far this morning all the 6m JT65 spots have been from G stations with the best DX 219km. No Es seen here as yet on 6m. At this distance this is either tropo or aircraft reflection. On 10m just one Es spot so far at 0938z by EA1FAQ (1249km) in northern Spain.

UPDATE 1208z:  Plenty of Es about now on 6m and 10m.
