10m WSPR (last Thursday)

The last time I was on 10m WSPR was on Thursday when I was spotted by 62 different stations in Europe and South America. And I thought most were now using FT8!! Not bad with 500mW and a low wire antenna. 

In the last week, 74 stations have spotted me on 10m WSPR.

Sunset - NOT amateur radio


This sunset from 2016 was a Facebook memory today. As I recall it was taken in a friend's garden.

These are the wild flowers by "our" windmill next door. They look stunning.

10m FT8 QRP (Friday)

 For a change, I am on 10m FT8 today. Power is 2.5W. Let us see what happens. All quiet at 0630z.

More cancelled rallies

This has not been a good year for radio rallies again, with most cancelled or postponed. Let's hope 2022 is better. 

The weekend another two have been cancelled: the East Suffolk Wireless Revival and the McMichael Rally.

Video channel

From time to time I like to remind readers of my video channel. This gives more details on some of my projects and some of my non amateur radio videos.

Almonry, Ely - NOT amateur radio

Yesterday, we went to Ely with my wife's brothers and wives. We had a snack in the Almonry, which has been serving drinks and meals since the 1200s.  I suspect the scones are not as old! 

This photo was in the Almonry Garden.

10m WSPR TX

For several hours I have been on 10m WSPR TX with 500mW. Nobody has spotted me yet at 1400z.

UPDATE 1530z:  All day had gone by without a single spot, despite my 2.5W 6m signal getting to Newfoundland and lots of 6m stations being copied. I was getting suspicious, so I reset the 10m WSPR beacon. Suddenly lots of spots! All very odd. Perhaps something with my timing was off. Anyway, all fine now. 
It seems that every time I try, I get spotted in South America on 10m WSPR. Not bad with a self contained unit (no PC needed) about the size of a pack of cards and a low wire antenna. My thanks to Jay, W5OLF for such a wonderful unit. It continues to give me hours and hours of fun.

Iceland - NOT amateur radio

We were in Iceland 10 years ago. There were lots of wild lupins and waterfalls. 

6m FT8 today (Thursday)

Stations spotting me to
1455z on 6m FT8 TX
Already spotted across the Atlantic on 6m FT8 TX as well as lots of spots nearer. 56 stations spotted on RX.

UPDATE 1455z:  182 spots of my 2.5W to the omni vertical V2000 so far. On 6m FT8 RX plenty of stations from North America and the Caribbean.

1620 pub - NOT amateur radio

Yesterday lunchtime we ate lunch at a pub nearby that has been a pub since at least 1620! 

It is amazing to think this was serving ale when the Pilgrim Fathers sailed to America 400 years ago!  The bit on the right was added about 150 years ago. Most is thatched.

The food and service were excellent. There were quite a few tables occupied, which is always a good sign.

This came to me via Steve G1KQH

I have no idea where this originated. 

Talk a lot? Radio amateurs? Surely not. Well maybe 80m nets! 😉

Phaser kits

These are QRP SSB phasing transceivers for FT8 designed by Dave Benson K1SWL. I have one (unbuilt) for 10m. My intention was to have a go at building it for the Es season, but I guess I shall miss this based on the time I get around to it!  Since my 2013 stroke, I have found building things far harder. Maybe it will have to be a winter project.

I think these are meant to be about 3-4W pep and take about 6 hours to build. That means 26 hours for me! The idea is to have a rig that can be on, but freeing up the "big rig" for other things.

Ely with sibs earlier - NOT amateur radio

This photo was taken earlier in Ely and shows my wife with her brothers. Ely Cathedral is in the background, 

2m activity contest (UKAC)

Every month the RSGB organises a 2m activity contest on Tuesday evenings. Last evening, I went on for far shorter than normal (because of the sibling reunion) with 5W and the big-wheel antenna.

Iceland - NOT amateur radio

 

10 years ago we went to Iceland for a holiday. We expected it to be barren, but it was green and beautiful with lots of wild lupins. This was the church at Vik. 

Sibling reunion - NOT amateur radio


Every year for 18 years bar two because of my stroke and Covid-19 we have had a sibling reunion with my wife's brothers and wives. We take it in turns to host. From next year we will meet in hotels as we are getting older!

Out pedestrian portable

Before I had a stroke, I quite enjoyed operating pedestrian portable. That is with a rig with a whip antenna on the set, not out portable with large antennas such as SOTA or POTA operations.

When the weather is good (it is raining here at the moment!) it is great fun. Seaside operation with good take-offs can be surprisingly good. If you have high noise levels at home, you can choose quiet places.

Wild flowers - NOT amateur radio

The ground next to the path near "our" windmill next door has been left so wild flowers can grow. It looks great.  

It was such a good idea. It encourages bees and looks good. I was amazed how quickly they grew.

10m WSPR TX (500mW)

 As the antenna was free, I decided to go on 10m WSPR TX again. Nobody has spotted me yet today.

UPDATE 1026z:  No spots yet today.

UPDATE 1152z:  So far today, spots from 2 stations with the furthermost EA8BFK (2880km).

6m FT8 today (Tuesday)

It is much quieter so far today. 

I have been on for about 30 minutes with 2.5W and the V2000, but only 3 stations spotted on RX and 4 stations spotting me on TX. 

Yesterday the FT8 slot at 50.313MHz was busy with plenty of Far East stations on 6m FT8.

UPDATE 0958z:  9 stations have spotted me on TX and I have spotted 12 stations on RX.

UPDATE 1155z:  18 stations have spotted me on TX and 22 stations spotted on RX. No super DX here today.

Homebrew 70cm antenna


This appeared as a FB memory today. It shows the antenna made from an old coat hanger for 70cm 8 years ago. The map shows the contacts with it. 

Yesterday on 6m FT8

For the first time since 2017, I spotted Japan on 6m. This time it was  FT8 with the V2000 vertical omni antenna.  Last time, with the same antenna, it was JT65.

With a beam at a decent height, I would expect to spot stations some 10dB weaker. I suspect I would copy Japanese stations every year on 6m FT8. 

Nonetheless, I was very pleased to spot Japanese stations on 6m FT8 yesterday with the V2000 omni antenna.

Afghanistan - NOT amateur radio

Why? 

We have been fighting wars in Afghanistan since the first half of the 19th century when Victoria was queen. Countless people have been killed or maimed. 

What will happen now the western troops leave? Most likely it will descend into civil war again and the Taliban will again fight for control. In many ways things will be as bad as when we arrived.

In my view, we should stop interfering. Yes, we wish to support democracy and freedom, but we do not exactly a good track record. Vietnam, Iraq, Afghanistan to name a few. 

We have a great record in soldiers and civilians being killed or maimed and wasting billions. Instead we could spend the money on fighting climate change.

Lightning

Although we may experience a few showers, it is quite warm outside. The thunder risk looks low with most storms over Denmark. 

I think there is some link between thunder activity and Es, although I have not studied it. I think it has something to do with sprites? There must be people who know far more than yours truly! If you know the link, please leave a comment.

10m WSPR TX (500mW)

At the moment I am on 10m WSPR TX and 6m FT8 RX. 

The W5OLF beacon is totally self contained (no PC needed) and about the size of a pack of cards. It is on 100%, but randomly changes frequency each slot. In the past it has been spotted in every continent with simple, wire antennas.

No spots yet at 1037z, although I have only just turned it on.

UPDATE 1137z: Just 4 WSPR 10m spots so far by F4CWN (969km).

UPDATE 1303z: 16 unique stations spotting me today.

UPDATE 1640z: 23 spots of me so far today.

First ever photograph of a person - NOT amateur radio

Photo from Wikipedia Commons
Recently I posted a photo of a man reported to be born in 1746. 

The first ever photo to capture a person is supposed to be a Daguerreotype taken in 1838. This is a street scene and shows a person having his shoes cleaned. This person had no idea he was making history that day! The photo was taken out of a window in Paris. The image here does not do it justice. The man having his shoes cleaned is in the bottom left.

Photography was invented (I believe) in the 1820s. Just imagine if we had had photography centuries earlier. Samuel Pepys would have been busy!

6m FT8 humming

Quite a few stations are calling the Far East on 6m, suggesting there is propagation from Western Europe to the Far East on 6m. This regularly happens at this time of year. 

It seems linked to noctilucent clouds that form about now, although I am not clear about the mechanism. It looks like E layer propagation, although I think multi-hop Es idea is wrong in my view! There would have to be so many hops and this makes this so improbable. It would not surprise me if we discovered some new E layer mechanism in the next few years. 

There are quite a few incorrect myths about. Never believe all you are told!! Look at facts and make up your own mind.

UPDATE 0908z: 149 stations spotted on 6m FT8 RX including 2 in South Korea and 1 in Japan, JA6SBW (9053km) being the furthermost. Although better equipped stations have been spotting and working the Far East, this is the first time I have spotted Japan on 6m since 2017. This is my first time I have spotted Japan on 6m FT8. I think my V2000 vertical omni needs signals to be strong to copy them although at -15dB S/N this station was quite strong here. On TX (2.5W) 37 spots, but no spots from the Far East unsurprisingly!

UPDATE 1112z:  50 spots of my 6m FT8 (2.5W) so far today.

UPDATE 1305z:  92 spots of me so far today on TX. 247 spots on RX plus several QSOs.

UPDATE 1644z:  133 stations have spotted me so far today on TX.  330 stations spotted on 6m FT8 RX today.

10m WSPR TX (500mW)

When I am on 6m FT8, I keep forgetting that my 10m antenna is not in use!  So, I am on 6m FT8 (2.5W) and 10m WSPR with the 500mW W5OLF WSPR beacon. Much to my surprise I got 3 spots on my first transmission with the furthermost TF4X (1995km) on 10m WSPR.  I shall leave the 10m WSPR TX running to see what other reports come in.

UPDATE 1242z: Glad I went on! Now being spotted in South America with 500mW.

UPDATE 1337z: Plenty of WSPR spots on 10m today. 

UPDATE 1534z:  Spots today on 10m WSPR by 13 different stations with the furthermost FY5KE (7110km).

UPDATE 1737z:
  32 different stations have spotted my 10m 500mW WSPR beacon today so far. Did someone say everyone now uses FT8? If so, they are wrong!! I like FT8, but have been blown away by the WSPR spots.

UPDATE 2000z:  
My 500mW WSPR on 10m spotted by 42 stations today. See table.

Still 7 - NOT amateur radio

We first saw these cygnets more than a week ago. Good to see there are still 7. This was at Anglesey Abbey. 

6m FT8 with 2.5W and the V2000 omni

As the antenna and coax were faulty, I had not been on 6m for some weeks until just now. The FT8 slot on 6m is filled with Es stations from Europe. I am on TX too. I wonder who I shall work? 

Within a very short time (a few minutes) I had been spotted across Europe by 25 stations and I have spotted 55.

UPDATE 1224z:  120 stations have spotted me and 2 QSOs.  225 stations spotted on 6m FT8 RX. When open, 6m Es is every bit as good as 10m in my view.

UPDATE 1411z: 235 stations spotted today on 6m FT8 RX. 5T5PA (3791km) in Mauritania, West Africa, remains the best DX spotted on 6m FT8 RX although I see Caribbean and USA stations are being worked. As I said before on this blog, a decent beam antenna at a reasonable height could be worth 10dB over my station, which can be a big difference on some signals. It means signals that I cannot even detect become workable.

UPDATE 1542z: Furthermost spotted today on 6m FT8 is A71AM (5138km)

UPDATE 1744z:  412 stations spotted today on 6m FT8. 

Stations spotted today
on 6m FT8 RX
UPDATE 1922z:
  530 stations spotted on 6m FT8 RX with the furthermost PV8DX (7830km). On 6m TX FT8 (2.5W) I have been spotted by 212 stations with several QSOs around Europe.

238 stations
spotted my 2.5W
6m FT8 TX today 
UPDATE 2122z: 
Spotted by 238 stations using 2.5W to the V2000 vertical omni antenna. The furthermost was a YU on RX in Niger, south of the Sahara (4200km). I was going to go QRT, but 6m is still wide open.
