10m antenna

 

At the moment 10m is excellent and there are some 10m only rigs at bargain prices. Many will have a go on 10m only where antennas are small and they do not have to be far off the ground to be effective. 

I know this has been on several times before, but it is worth reminding folks of my 10m antenna that can be made from easily obtainable material, is small and really works. If you are after a simple 10m antenna, this may "fit the bill".  It was in Practical Wireless many years ago and is on my website.

Stations
monitoring
8m FT8

 No spots. The map shows the stations currently monitoring 8m FT8 - quite a few!

UPDATE 1249z:   5 stations have spotted my 8m QRP FT8 and I have spotted 2 and had a QSO with 1 station in Spain.

Stations spotting
my QRP 8m FT8

UPDATE 1745z:  3 QSOs, 9 stations have spotted me and I have spotted 17 stations.

Fuchsias - NOT amateur radio

 

October is often a wet and windy month so it is good to be cheered up by flowers in the garden.

10m 500mW WSPR TX (Tuesday)

 As well as spots of me by G4KPX (14km) and EA8BFK (2880km) I am getting spots from YO3BN (2083km). I assume the latter is via F2.


UPDATE 1546z: 
USA and Canada coming through with 56 spots of my 500mW WSPR from "across the pond".

UPDATE 1809z:
75 stations have spotted me today. See Phil VK7JJ 's WSPRrocks website.

UPDATE 2056z:  80 spots of me today.

Sunspots - Tuesday October 1st

 Solar flux is 214 and the SSN 150. A=11 and K=2.

Openings to Eastern Europe?

It looks like there are openings to Eastern Europe on 10m and 6m from Western Europe. I am hoping there is some activity on 8m and that it spreads further west.

See https://www.tvcomm.co.uk/g7izu/radio-propagation-maps/europe-sporadic-e/ .

10m 500mW WSPR (Monday)

 So far, just G4KPX (14km) and EA8BFK (2880km) spotting me.

UPDATE 1402z:  USA and Canada coming through now with 17 stations spotting me. See table.

UPDATE 1646z:  28 stations have spotted me.

8m FT8 (Monday)

Although my 2.5W 8m FT8  has been on for much of the morning, no spots on TX or RX.

UPDATE 1117z:  Although no spots yet, it is interesting to see so many stations monitoring the 8m band. See the map of monitors.

UPDATE 1300z:  Still no 8m spots today.

UPDATE 1326z:  Spotted by EI3KF (574km). Is this aircraft scatter? I am sure there are far more 8m monitors, which is a good sign.

UPDATE  1521z:  QRT on 8m.

Oil prices - NOT amateur radio

With all the increased tension in the Middle East I am surprised how little prices have moved. I remember back in the Suez crisis of 1956, petrol was rationed again. It is as if the world either expects a ceasefire or knows how to cope if the Gulf is closed. 

Are we far less dependent on oil from the Middle East?

Maudlin thoughts - NOT amateur radio

My brother will be 80 in December. He seems to be going to several funerals of late. I guess we are now at an age when many of our friends and relatives get serious illnesses or die. 

I wonder if our brains modify to accept this as the norm? 

It is interesting how we now talk about illnesses more as we age. There are several friends and relatives who are now in the "firing line". In the past we assumed we would all go on forever. Now we think of our finality.

Once we went to a New Year's Eve party. The host said, "you are not allowed to talk about illnesses". What a good idea!

UPDATE 1433z:  We just heard that one of my wife's best friends has died.  Not unexpected, but so sad for those left behind.

Monday plans

Later, I hope to go on 10m 500mW WSPR and 8m QRP FT8. 

In all, stations in 3 countries spotted my 2.5W 8m FT8 yesterday, which was better than I expected.

Sixbox 6m transceiver

This dates back many years and is not recommended when 6m is "open" as it has been recently. 

On the other hand, it makes a nice homebrew project and an ideal natterbox across town. 

As I always say, use it as a starting point for your own ideas. For example, add a loudspeaker amplifier, or increase the RF power. Most of my designs are starting points and could usually be improved. Do not be afraid to experiment as this is where a lot of the fun is.

Inside the windmill - NOT amateur radio

The outside of the windmill next door has featured many times on this blog. 

The inside (as far as I recall) has never been on, until now. This is inside the windmill.

Fitzball’s house - NOT amateur radio


 Edward Fitzball was a famous lyricist in the 1800s . He lived in this cottage in our village (Burwell).

Sunspots - Monday September 30th

 Solar flux is 197 and SSN 154. A=16 and K=2.

War and peace - NOT amateur radio

 One thing I am certain about - wars rarely settle things, often resulting in long-term distrust and hatred. 

In the Middle East this is true at the moment. For many years Israel has had people opposed to the very state of Israel. At the same time Israel has opposed the existence of the people of Palestine. There is much bitterness.

Surely, the only long-term solution, no matter the past history, is peaceful co-existence.  Everyone on the planet has a right to peace.

8m QRP FT8 (Sunday)

My 2.5W 8m FT8 has been on since breakfast. So far, nobody has spotted me, but ZR1ADI (9777km) spotted on 8m FT8 RX.

UPDATE 1022z:  My QRP 8m FT8 spotted by G4OGI (123km).


UPDATE 1805z: 3 stations have spotted me on 8m today. See map. Now QRT.

10m QRP WSPR TX (Sunday)

 My stand-alone 10m WSPR TX has been on since breakfast. 


UPDATE  1751z: 
31 stations have spotted me today.  See table. QRT shortly.

Valve QRP

This was several years ago at the QTH of G6ALB. Andrew did the building of this valve Sputnik TX and I did the operating. After about 10 minutes a CQ call on 15m resulted in a contact with a station in the USA. Present were G4NUA (SK), G6ALB and G3XBM (me). What fun we all had!

Tidy up - NOT amateur radio


 Yesterday, many volunteers tidied up our local bowling green. I think they must have a match this weekend.

Amateur radio on the streets?

Around the world it seems harder to find radio magazines on the stands of newsagents. This is certainly true here in the UK, but I am wondering if it is different in other countries?

Yaesu FTX-1F

This radio is creating quite a buzz. 

It is Yaesu's answer to the IC-705 and it also is the long awaited answer to the FT817/818 series. 

It is not a hand portable, although I suspect Yaesu have done their homework in that most people will not use it pedestrian portable but in hotel rooms and on park benches. In this regard it may be an ideal choice with a large battery capacity.

So far, there is no indication of price, but I hope it is well under £1000. Also, we have only, so far, seen very preliminary specs. The IC-705 has things like Bluetooth and GPS. It will be interesting to see what appears in the full specs.

Often there are hardware and software bugs in very early models.  This will be the first time that Yaesu will have made units in significant volumes, so they will be looking for feedback so they can "tweek" the design on the next production run. In some ways early adopters are guinea pigs.

Soldersmoke AI experiment

As an experiment, Soldersmoke did an experimental AI generated podcast. It is frightening. 

If this is possible now, what will be possible in 2050? To me, it sounded incredible. You would never have known it was AI generated.

It is frightening how realistic this podcast sounds, making you wonder how AI could be used to distort truth in future e.g. in elections.

Sunspots - Sunday September 29th

 Solar flux is 195 and the SSN 148.  A=7 and K=3.

Dying of cancer - NOT amateur radio

 My wife has been to see her old work colleague and friend several times recently. 

After a long battle with stage 4 cancer she has come home to die. They gave her less than 5 years, but she has lasted 8 years. She probably only has days left. It is all so sad. She sleeps a lot of the time and is confined to bed. 

It is odd. In some ways this experience has dulled the fear of death. For her husband it must be unbelievably sad knowing that your wife is dying and there is no prospect of her getting better.

Apple day 2024 - NOT amateur radio

Our next door neighbour has a large orchard and far too many apples, so he organised an apple day so we could pick some for the winter. 

For once the weather was sunny and bright.

It was a lovely social occasion too.

10m 500mW WSPR (Saturday)

My stand-alone 10m WSPR beacon by W5OLF was turned on at about 0835z.  No spots.

UPDATE 0848z: Just a couple of spots by local G4KPX (14km).

UPDATE  0855z:  Just G4KPX spotting me.


UPDATE 1556z: 
33 stations have spotted me with many in the USA and Canada.


UPDATE 1603z: 
The map (see WSPRrocks by Phil VK7JJ) shows the stations spotting my 500mW 10m WSPR TX beacon today.

UPDATE 1629z:  36 stations have spotted me today.

8m QRP FT8 (Saturday)

My 2.5W 8m FT8  was turned on at about 0835z.  

UPDATE 1317z:  QRT.  No spots all day on RX or TX on 8m FT8.

UPDATE 1703z:  On again, but still no spots. So far, I have been disappointed with 8m FT8 this autumn.

Crab apple jelly - NOT amateur radio

A few days ago I collected the crab apples from our single tree. 

Yesterday, I turned them into crab apple jelly as the photo shows. It is delicious on some meats.

I have no idea why they are called crab apples. They are tiny compared with more usual apples. I would guess 2cm diameter or less would be more typical.

See https://www.bbcgoodfood.com/recipes/crab-apple-jelly .

8m later

 Now my 8m dipole has been re-erected, I intend to try the band again later.

Sunspots - Saturday September 28th

 Solar flux is 186 and the SSN 122. A=6 and K=0.

'Our' tree - NOT amateur radio

We keep an eye on this tree at Anglesey Abbey throughout the year. At the moment it is turning into its autumn colours. After a few weeks of strong winds, it will be bare until the spring.

10m 500mW WSPR (Friday)

 My 10m 500mW WSPT TX beacon was turned on at about 1630z.  EA8BFK (2880km) has spotted me.

UPDATE 2035z:  In the end 2 stations in the USA spotted me (see table).

Anglesey Abbey yesterday - NOT amateur radio

 

Yesterday we met some friends at Anglesey Abbey. There was rain overnight and rain this afternoon, but we chose a dry patch in between luckily.

Back on 8m

 My grandson helped me re-erect my 8m dipole. At about 1600z, I restarted my 40.680MHz 2.5W FT8.

Late swallow - NOT amateur radio

Yesterday as well as seeing a couple of house martins I saw a late swallow. 

This is probably the last I shall see until the spring. I am pretty sure this is the latest I have ever seen one up here in East Anglia.

Sunspots - Friday September 27th

 Solar flux is 181 and the SSN 169. A=13 and K=2.

Cyber attack? - NOT amateur radio

 I heard yesterday that all the major UK rail station WiFi systems had suffered what was thought to be a cyber attack. If these can be attacked what else could be done?

Autumn and winter project

During the dark evenings this autumn and winter I intend to update my PDF Project Scrapbook. There have been a few changes to rigs that I should include. Also, there is more to say about 8m and 23cm.

6m QRP FT8 yesterday

Despite the main Es season being now well over, there is still some DX to be found. Yesterday with 2.5W FT8 my 6m signal was spotted in several places in mainland Europe. See map.  It is not the same as at the peak of the "season" yet monitoring can yield results.
