Sunspots - Sunday February 23rd

 Solar flux is 199 and the SSN 215. A=6 and K=1.

FT8

Some like it and some hate it. 

I agree that if you believe amateur radio is about 2-way chats, possibly with stations across the world, then FT8 is not for you.  Also, with FT8 people will not chance upon amateur radio as many of us did on AM years ago.

In my own case, I have little alternative as my voice is very poor these days!  FT8 works with very weak signals and only occupies about 50Hz whereas SSB takes about 2.3kHz. With FT8 exchanges are very basic.

I am "on the fence" over FT8. There is no way without FT8 nearly 900 stations would have copied my 5W on 10m  today. 

At the same time, I really believe modes like FT8 could lead to the end of amateur radio as we know it.

LORA DX

On Amateur Radio Weekly yesterday was a small yagi to extend the range of LORA systems. They were claiming a range of 40km, although I expect that was line-of-sight. LORA is a long range, licence free, data system using spread spread spectrum techniques.

Norwich - NOT amateur radio

 

Yesterday, I mentioned going to Norwich by train. It is a journey of about an hour. We love Norwich. The photo shows the arrival at the station in Norwich. It is about 1km walk to the splendid Norman cathedral.

Almost spring - NOT amateur radio

 

After what has seemed like a long, wet and dull winter, today felt more like spring. 

For the first time in months it felt mild outside so much so that I pruned my roses. Every year they grow well for a hard prune early in the year. Opinions vary about when and what to do, but I shall stick with what works.

We have had no snow, but several frosts. It is also wetter than I remember. I am sure we have not done with winter yet, but at least there is a hint of spring.

10m QRP FT8 (Saturday)

 At the moment I am on 10m QRP FT8 with 5W from the IC-705.

UPDATE  0958z:  So far, I have been spotted by 39 stations, despite only being on for a few minutes.

UPDATE 1030z: Spotted by 114 stations. On RX the furthermost is the Solomon Is H44MS (14814km) in the Pacific.

UPDATE 1803z:  774 stations have spotted my 10m 5W FT8  today. 1549 stations have been spotted today on 10m FT8.

Sunspots - Saturday February 22nd

Solar flux is 197 and the SSN 138. A=6 and K=0.

Norwich by train - NOT amateur radio

Today we went to Norwich by train. It’s about an hour by train. Norwich is a fine city with a good Norman cathedral. 

Sunspots - Friday February 21st

 Solar flux is 184 and the SSN 123. A=7 and K=0.

Human consciousness - NOT amateur radio

We hear a lot these days about AI. One of my Cambridge University of the Third Age courses is about AI. It is very good and thought provoking.

At the moment AI is not very good with irony or jokes. No doubt with time and better training this will improve.

I guess what we fail to really understand is human consciousness. Just what makes us able to think, become aware of ourselves etc.? In my mind there is a huge difference between the accumulation of all the knowledge on the internet, and of wisdom.  AI can learn all about all the knowledge on the internet, but still not be wise or be able to contemplate its very existence.

At some point I wonder if we will be able to say exactly what human consciousness really is?  In many ways this is a philosophical question.

Milder? - NOT amateur radio

In this part of the UK it is meant to be getting much milder, with a hint of spring. It is quite windy here and I have not noticed it getting milder yet.

Roll on spring!

8m QRP FT8 (Thursday)

Once again, I am on 40.680 MHz FT8 with the FT817ND hoping for some spots.

UPDATE 1134z:  Just one spot by EA8RCP (3022km) of me so far today. I estimate about 2.5W to the low dipole.

UPDATE 1411z:  Now also spotted on 8m FT8 by EI4DQ (580km).

10m 500mW WSPR TX (Thursday)

My beacon was turned on just before breakfast.

UPDATE 1139z:  Just EA8BFK (2880km) spotting me. It seems the single hop F2 to the Canary Is is often open. Interesting that reports of me vary from -25dB S/N to -5dB S/N on this path. This implies he could still  copy me with microwatts at times!

UPDATE 1640z:  26 spots of me with the furthermost Brazil. 

Sunspots- Thursday February 20th

Solar  flux is 178 and the SSN 119. A=20 and K=2.

Cambridge bookshops - NOT amateur radio

At one time there were lots of bookshops in Cambridge. These days we buy many books online so there are fewer bookshops.  

This one has been around for a very long time. See the photo. 

Old work colleague

A few moments ago I sent an email to an old work colleague who now lives in Moscow. He is a very keen radio amateur who has done a great deal for the hobby.

This is one thing I really like about amateur radio. Whether the person lives in the USA, China or Russia matters not one bit. We are all human beings and all equal. In the days of the USSR it mattered not and Americans freely talked to stations in the USSR.

Amateur radio is above politics.

Let's hope the thought police don't come knocking!!

Ukraine - NOT amateur radio

The Ukrainian 🇺🇦 leader is not impressed with President Trump!! I can't say I blame him.

Archetypal Cambridge - NOT amateur radio

Whenever you think of Cambridge you may think of punts and fine weather. Well, today we had the punts, but not the fine weather! It was very cold.

Bite sized chunks - NOT amateur radio

 One of the things I remember from a time management course at work a long time ago was to think of issues in bite sized chunks. Every problem has a solution.

I am reminded of a famous quote by Descartes:

"Divide each difficulty into as many parts as is feasible to resolve it"

See https://www.brainyquote.com/authors/rene-descartes-quotes.

Basically every problem, however complex, can be solved.
