Optical DX - NOT amateur radio

For years I have been fascinated by mirages and increases in refractive index at optical frequencies. What is often not realised is that how far we can see changes depending on the refractive index .This photo was a Facebook memory from some years ago.

Sunspots - Wednesday December 11th

 Solar flux is 172 and the SSN 125. A=8 and K=2.

Notre Dame, Paris - NOT amateur radio

This was badly damaged by fire 5 years ago (my half French grandchildren cried buckets) but has now been reborn . 

This is it now.

How ignorant we are - NOT amateur radio

 As part of my University of the Third Age course in Cambridge I was studying great physicists. The take-away remark is just how little we know! 

For centuries great minds have tried hard to better understand the universe at macro and micro level, without really understanding it.

Quantum mechanics was only put forward a little over one hundred years ago. All we really know is that everything is stranger than we ever imagined.

I don't think our human brains are capable of fully comprehending this.

Next term I am studying "Computers, the Brain and AI".  Perhaps AI could help?

The other course (totally different!) was about the Balkans.

 Solar flux is 173 and the SSN 94. A=16 and K=2.

Rethatching - NOT amateur radio

In the nearby village of Lode there are many thatched cottages. One is having its thatched roof replaced, a job that takes many weeks. The one in the photo has been worked on for about 2 weeks already.

10m 500mW WSPR TX (Monday)

My beacon was turned on at breakfast time. At  0902z, several spots from the Canary Is..  It seems this (I assume) single hop F2 path is usually open.

UPDATE 2005z:  48 stations have spotted me today.

6m QRP FT8 (Monday)

 My gear was turned on just after 0800z. At 0858z already 20 stations have copied me including several in mainland Europe.

UPDATE 1957z:  71 stations spotted my 6m QRP  FT8.

Sunspots - Monday December 9th

 Solar flux is 178 and the SSN 103. A=7 and K=3.

Beware!!

Earlier this afternoon I thought I had ordered a UV K5(8) transceiver from Aliexpress for the bargain price of just £0.98 with free airmail postage. 

At this price (well below the price of a coffee) I thought I could not go wrong. 

Later, I read the reviews. One pointed out that all you got was the antenna, despite it implied you got a full transceiver for this price. This is a total scam.

I cancelled the order immediately.

It must be near Christmas - NOT amateur radio

Today, we put up our Christmas tree and Christmas decorations. It must be the run-up. 

It seems 5 minutes since last Christmas.

10m 500mW WSPR (Sunday)

My QRP 10m WSPX beacon was turned on at about 0800z. At 1006z, 7 European stations  have copied my QRP.

UPDATE 1855z:  47 stations have spotted me today.

6m QRP FT8 (Sunday)

UPDATE 2000:  55 stations have spotted me with 2 from "across the pond".

Oscar 100 narrowband transponder

Every few weeks I take a look at the narrowband activity on the geosynchronous Oscar 100 satellite. I am disappointed by the lack of activity.

The evolution of languages - NOT amateur radio

My family history can be traced back on my dad's side to the mid 1500s. This was 13 generations. Being generous, it takes about 60 generations to get back to the Roman invasion of England and the birth of Christ. 

Now, I have no idea when certain languages began, but we have so many very different languages in Europe at the present time. Some are right next door as countries e.g. France and Germany. It is estimated that there are between 5000 and 7000 languages on Earth.

What I find so amazing is that our languages can be so different. OK, until about 100 years ago most people did not move far. Nonetheless, I find it incredible that languages can be so different in so few generations.

See https://en.wikipedia.org/wiki/Language.

New radios

Looking forward, certain things seem apparent to me. These are:

• Manufacturers want to be competitive. This usually means high volumes and low variations between markets. For example products for the USA market should have the same hardware as for Europe and most of the world. Programming with different software is easy.
• People are finding prices high, so are looking for good value and to buy as few products as possible. The "shack in the box" looks attractive.
• Ideally many would like a radio that can do all bands (HF and VHF) in all modes. 
• A radio that could be used in the shack or car/truck means fewer variants, so higher volumes.
• Small size makes fitting in small spaces easier.
• Manfacturers must be mindful of low cost manufacturing areas around the world.

One solution might be a low power product with a separate linear?

So an ideal product might be the ICOM IC-705 or the Yaesu FTX-1F.

In my view the companies that will remain around are the ones that recognise these and develop products accordingly.

Sunspots- Sunday December 8th

 Solar flux is 183 and the SSN 91. A=6 and K=1.

Winter projects

Here in the UK it is now very dark in the mornings and it gets very dark early in the evenings too. We are drawing the curtains at about 4pm whereas it seemed like 5 minutes since we were doing it at 10pm!

With the onset of winter, many people turn to winter amateur radio projects. These days, my fine motor skills are poor, but in the past "rolling something of my own" has given me immense pleasure. 

I cannot describe the thrill of working somebody thousands of miles away on something you have designed and built yourself.  

However small, I can recommend building something. Maybe start with a kit?

Naughty but nice - NOT amateur radio

 This was the advert for breakfast at a local pub. Very nice 😊.

Tangerine Dreams - NOT amateur radio

Despite being re-potted and staked our very tall amaryliss decided to fall over again in the night, so we put it in the sink of the utility room weighed down with.......tangerines! 

Since this it has not (yet) fallen over.

10m QRP WSPR TX (Saturday)

 My beacon has been on since breakfast. At 0943z, 6 stations have spotted my 500mW.

UPDATE 1325z:  21 stations have spotted me so far.

6m QRP FT8 (Saturday)

My gear was turned on at breakfast time. So far, 15 stations spotted today at 0928z. See map.

UPDATE 1322z:  40 stations have spotted me today.

Sunspots - Saturday December 7th

 Solar flux is 178 and the SSN 103.  A=5 and K=1.

Christmas spirit - NOT amateur radio

This was the entrance to our local museum last weekend. They had a very happy "Father Christmas" day that was very successful. 

All the kids (and adults!) had a really good time.

6m QRP FT8 (Friday)

My QRP FT8  to the V2000 vertical omni antenna has been on since just before breakfast. 22 stations have spotted me. See map.

UPDATE 1538z:  Now spotted by 42 stations with the furthermost DU6/PE1NSQ (11141km).  On 6m FT8 RX an XV8 was spotted working a Swedish station. See map with bars for stations that spotted my 6m FT8 QRP today.  See table for the stations received here today on 6m FT8.

10m 500mW WSPR TX (Friday)

 My beacon has been on since just before breakfast. 2 stations have spotted me so far

UPDATE 1552z:  Spotted by 31 stations. I think this is via F2 propagation. See table.

King's College Chapel - NOT amateur radio

The Christmas service of nine lessons and carols from here is watched around the world by about 370 million people.  Some people queue all night for tickets.

It was quiet yesterday.

Friday plans

Later this morning I hope to go on 10m QRP WSPR and 6m QRP FT8.

Sunspots - Friday December 6th

 Solar flux is 175 and the SSN 101. A=5 and K=2.

2m activity contest last Tuesday

As usual, I went on for a very short while with my 10W and omni antenna. I do not stop long because of my poor voice. The map shows the stations contacted.

Rallies this Sunday

 The following have been notified to me. Always check before going far.

• British Vintage Wirelesss Society (BVWS)  Swapmeet and auction. Royal Wootton Bassett. BVWS members only.
• Mid-Devon Amateur Radio and Electronics Fair 2024, Winkleigh, EX19 8HZ. Contact wrg2024@hotmail.com .

France - NOT amateur radio

France has just lost its Prime Minister in a vote of confidence. It has a huge public debt. 

Time and again the French government has given in to large demands. In the end, the country cannot afford these so there will be cuts, which will be deeply unpopular. 

Usually when this happens people move to the extreme right or extreme left. I think France, and possibly the whole of Europe, is at dangerous cross-roads.

Wild Shetland - NOT amateur radio

This photo by friend Richard Lewis was posted on 365project. 

It captures the strong winds they often get up there.

10m 500mW WSPR TX (Thursday)

My stand alone QRP W5OLF WSPR TX beacon has been on since about 0915z. No spots yet. 

UPDATE 2232z:  38 spots of me today. QRT.

6m QRP FT8 (Thursday)

 My gear was turned on at about 0915z. So far,  6 English stations spotting me.

UPDATE 1330z:  30 stations have spotted me and 23 stations spotted here. Nothing "across the pond" on 6m FT8 today.

10m AM QRP transceiver

Before my 2013 stroke I intended to design and build a very simple 10m AM transceiver for nattering across town when 10m is not open for DX such as around sunspot minimum or at night. 

I wanted it to be on a simple PCB and easily built , for example as a club project. In my mind I had a box a bit like a very small Heathkit Benton Harbour Lunchbox. 

With this RX it would not be suitable for DX working as it will not receive SSB. The RX is very sensitive though. 

As it stands it wants taking further with a loudspeaker amplifier and perhaps a small linear. I was hoping someone would take this on and finish the project.

Sunspots - Thursday December 5th

 Solar flux is 175 and the SSN 105. A=6 and K=2.

Oops - NOT amateur radio

 

Our amaryllis toppled over as it was too tall! 

I am sure my wife will be able to rescue it and add a stake.

UPDATE 1545z:  All fine again. Rescued!
