10m QRP FT8 (Saturday)

Stations spotting my 2.5W
10m FT8 up to about 1120z

10m FT8  is "humming" with plenty of stations spotted with the furthermost VK3WK (16832km). In all, my 2.5W FT8 has already been spotted by 161 stations. The map shows the stations spotting me until about 15 minutes ago.

Stations spotted here
on 10m FT8 today

UPDATE 2052z: 
 So far today, I have spotted 565 stations on 10m FT8 and 346 stations have spotted my 2.5W 10m FT8 today. QRT shortly.

Sunspots - Saturday August 24th

 Solar flux is 242 and the SSN 180. A=7 and K=3.

OFCOM updates

OFCOM regularly updates the information it holds on licence numbers etc.. Please see the OFCOM website for the latest.

365project - NOT amateur radio

One of the things I like about 365project is seeing a "window on the world". 

The idea is to post a photo a day. At $19.99 you can have more albums and privacy, but otherwise it is totally free. It has no connection whatsoever with Microsoft.

This photo was taken in the Faroe Islands and recently posted. This is a place I am very unlikely to visit.

OSCAR 100 activity


Every few weeks I like to give an update on the narrow-band transponder of this geosynchronous satellite. It has been in orbit now for several years. 

Apart from those keen to assemble a ground station (fixed, small antenna, no tower, much of the world in range day and night, no QSB etc.) it has been under-used. 

The last peek was a Friday evening in Europe. Once again it was sadly quiet. 

It has never appealed to me, but I was quite surprised it was not more popular. Based on this satellite, I can't see another for some time.

By now, I was expecting it to be busy. It is not.

Homegrown tomatoes - NOT amateur radio

For some reason, tomatoes grown yourself always taste better! 

With the tomato bags, feed etc, I am sure they cost more than at the local supermarket, but they smell and taste great. These are some of the first this year.

Yaesu competitor to ICOM IC-705?


Although not available until next year MLS has announced a Yaesu competitor to the ICOM IC-705. At the moment I don’t know the price, but it has to be well below £1k to compete with the Chinese . This HAS to sell well for Yaesu's sake. Expect the IC-705 to drop in price!

The exchange rate against the Yen has improved a lot in the last few months.

I wonder if Yaesu has considered designing in Japan but manufacturing in a low cost area?

More something for nothing

 

Many years ago I experimented with this QRP transceiver circuit on 80m CW. It is hard to find anything much simpler!

Granddaughter - NOT amateur radio

 

This was one of my granddaughters yesterday at our home.

My dad over 100 years ago - NOT amateur radio

 


This was my dad over 100 years ago at Infants School. He is in the back row 4th from the right.

10m QRP (Friday)

Currently on 10m FT8 with my 2.5W. 

UPDATE 0929z:  Spotted by 62 stations already this morning and on RX the furthermost (115 spotted!) is VK6RK (14469km). 

Stations spotted here in the last day on 10m FT8

UPDATE  2024z:
  132 stations have spotted me today on 10m QRP FT8. 705 stations spotted here in the last day (see map).

Sunspots- Friday August 23rd

 Solar flux is 231 and the SSN 175. A=10 and K=2.

10m QRP FT8 (Thursday)

 About an hour ago, I decided to go on 10m FT8 instead of WSPR. 

UPDATE 1715z:  43 stations have been spotted and 4 stations have spotted me. See map for the stations spotted here today.

UPDATE 1905z:  Spotted by 9 stations with the furthermost ZS1TX (9753km). 69 stations spotted here on RX.

Tenner - QRP CW on 10m

This rig is many years old. It is simple, but it worked lots of DX. 

As I recall, it produced about 500mW of CW.

Baby crocodile - NOT amateur radio

 

When I saw this twig on our walk yesterday, I immediately thought of a baby crocodile. 

I know it is not, but it is funny how the mind works.

Solar peak - cycle 25

My favourite site for solar data is now showing the smoothed peak of cycle 25 as this October at 162.8. At one time they were showing a much smaller peak last November. 

This suggests good F2 conditions this autumn and spring.

10m 500mW WSPR TX (Thursday)

My beacon was turned on at about 0800z. 

UPDATE 1525z:  No spots. I suspect fewer people use WSPR now preferring FT8. Perhaps I should try 10m FT8 tomorrow?

6m QRP FT8 (Thursday)


My QRP 6m FT8 was turned on about 0800z.  


UPDATE 1046z:  10 English stations have spotted me See map.

UPDATE 1255z:   11 stations spotting me.

UPDATE 1518z:  12 stations have spotted me. See map.

Websites and dates

This really annoys me. It would be really helpful if people put dates when webpages were updated. I can’t tell you how often I have seen data only to see it was created some years ago and the data is out of date!! 

As an example CQWW contest website. Dates are shown for 2024, but were these written last year? The last blog update was April. 

This has happened so many times. All it needs is a footer saying when the webpage was last updated.

Sunspots - Thursday August 22nd

 Solar flux is 239 and the SSN 176. A=8 and K=2.

Brandon Country Park - NOT amateur radio

This is about 30km from us. 

It has a series of lovely woodland walks with plenty of heather in bloom on the heath as the photo shows.  

As you would expect with a large quantity of trees, many are felled or fall down naturally.

10m 500mW WSPR (Wednesday)

Whilst on 6m, I keep forgetting the 10m antenna is available, so I can use my 10m WSPR TX beacon.

UPDATE  0952z:  No spots of me.


UPDATE 1715z:
  Spotted by 6 stations.

6m QRP FT8 (Wednesday)


My 2.5W 6m FT8 was turned on about 0800z. 

UPDATE 0843z:  Spotted by 9 English stations. It makes you think how useful 6m FT8 could be inter-G when the band is not "open". Also many of those spotting me so far are probably cross polarised and using horizontal antennas. Just one G spotted on RX.

UPDATE 1721z:  20 stations spotted.  One might be Es.

CQWW contests?

As I recall, CQ magazine has stopped. At one time the CQWW contests were perhaps the most popular in the world. Even without submitting an entry, it was a way to contact new countries. When my voice was good I used to fill pages in the logbook. In later years, it has become too hard for me.

With the demise of CQ, I wonder what is happening with these contests?

Sunspots - Wednesday August 21st

 Solar flux is 244 and the SSN 200. A=7 and K=3.

8m or 6m?

In recent times, I have not been on 8m much, even though I have a UK T&I permit to TX on the 8m band. 

The main reason is I know what the band can do with Es. It is possible to span the European continent with just a few milliwatts of FT8 on 8m. 

The 8m band, being between 10m and 6m, comes into its own when the F2 MUF just exceeds 47MHz. 

With the sunspot count being good recently, it has exceeded 50MHz, especially on N-S paths.  Activity on 6m is much higher, so getting spots is easier than on 8m currently. 

As the F2 MUF goes down, I expect 8m will be more useful showing how the F2 MUF can reach 8m, but not 6m. I shall probably try again on 8m this autumn It would be great if more PTTs allowed amateur access. 

I hope the FCC, OFCOM and the RSGB are listening!

Moulton flowers - NOT amateur radio

As mentioned before, Moulton (near us) is a delightful village to walk around, with an old packhorse bridge, the church, river, thatched cottages and flowers.

6m QRP FT8 (Tuesday)

My QRP 6m FT8 was turned on after breakfast.

UPDATE 0824z:  12 stations have spotted me. I think there is some Es.

UPDATE 0901z:  IS0AWZ (1598km) has spotted me. See map.

UPDATE 1521z: 24 Europeans plus one CN8 have spotted me so far today. See map.

Changing images on my blog - NOT amateur radio

Quite often I need to change an image on my blogspot blog. I find this very "hit and miss". Sometimes I can do it easily and other times I struggle.  I can't help thinking I am missing a trick and there must be a better way. 

Does anybody know a method that just works please?

6m super DX

As well as being spotted in Namibia 🇳🇦 yesterday with 2.5W FT8 to the V2000 vertical omni antenna a PY way down in Brazil 🇧🇷 (Sao Paulo) was spotted on 6m FT8 yesterday. See map.

Sunspots - Tuesday August 20th

 Solar flux is 239 and the SSN 213. A=10 and K=1.

FETer transceiver (2008)

This was another of my attempts to get something for nothing! 

It worked remarkably well, but I struggled with netting the RX onto the TX frequency so I was afraid of clobbering someone else. It was an adaption of a circuit for 40m by W2UW but made even simpler. It appeared in SPRAT some years ago. 

Some have duplicated it and achieved some remarkable DX.

Over the horizon on 481THz (optical)


Before my 2013 stroke I enjoyed experimenting at optical frequencies and was amazed that I could decode my QRSS CW well over the horizon with no clouds in the sky. Sadly, my stroke put an end to this. The circuit diagram shows the beacon I used. As you can see it is simple.

Winter in Brisbane, Australia - NOT amateur radio

Yesterday our son sent us this photo showing Brisbane in winter. Even in winter it was 30 deg C! 

The Internet

We all take instant global communications for granted. 

As an example yesterday we had a (free) video call from our son who is staying with his Australian in-laws in Brisbane. The quality was excellent. It was almost as if he was in the next room. 

It has not always been easy. I was surprised to read how extensive the telegraph network already was in the mid 1800s. Before that, news was very slow depending on boats, pigeons and dispatch riders. Just imagine life now without the internet. We have grown dependent on it in so many ways.

Just for chatting, we no longer need amateur radio.

Pathfinders - NOT amateur radio

I have just finished reading a book about the RAF Pathfinders. My dad was one in WW2. I had no idea how brave they were. On every mission they must have been terrified. No wonder my dad did not want to talk about his wartime that much.

My dad died in 1987. I think his wartime experiences haunted him. Overall, he was a peace loving man who enjoyed his quiet life. What a pity he died before I really understood. RIP dad.

The book by Will Iredale is available on Amazon and I expect it may be ordered by most bookshops.

Most wars serve no good.

6m QRP FT8 (Monday)

My 2.5W FT8 has been on most of the morning.

UPDATE  1032z:  So far, spotted by 14 stations mostly in England. The spots in Southern Eire and Norway could be Es.

UPDATE 1336z: Spotted by 19 stations. 

UPDATE 1814z:
   28 stations have spotted me today including V51MA (8460km) in Namibia.  6m TEP? See map.

Sunspots - Monday August 19th

 Solar flux is 231 and the SSN 170 . A-=12 and K=2.

Most from the least?


One of the things I like is seeing how much I can get from something not costing much. 

There are plenty of designs for regenerative receivers around, but I was pleased with this one. I am sure it may be improved.
