Mike Rainey AA1TJ?

When you don't hear about people for a while, you worry. 

A few days ago I chanced upon a circuit by AA1TJ and realised I had not heard any news from Mike in a while. Does anyone have any news please?

Like every person from the USA I have ever dealt with he was kind and generous. 

UPDATE  1910z:  Just had an email from Mike. Great.

10m 5W FT8 (Sunday)

My 10m QRP FT8 was turned on at 1144z.

UPDATE 1149z: So far, spotted by 13 stations.

UPDATE 1252z:  Currently 10m FT8 RX only. 249 stations spotted.


UPDATE 1656z
:  662 stations spotted here. See map. Seeing this 5W radio (QDX-M) is about the same size as a pack of cards, i.e. tiny, I am very impressed! Actually it is probably smaller than a pack of cards!  My antenna is just a low end fed. Now QRT.

Archetypal Cambridge

When many think of Cambridge, they think of King's College Chapel, punts on the Cam and weeping willows. 

Yesterday we had all three in one photo ....and blue sky!

IPSOS radio listening survey


In the last week I have been recording the broadcast radio stations that I have listened to as part of an IPSOS survey.  Mostly it is BBC Radio 4 around breakfast time.

OFCOM is consulting on the future of radio broadcasting in the UK.  According to them AM broadcast listeners have been declining.  I am not sure if this is true or as a result of more people listening to traditional broadcasts via smart speakers and DAB. Yours truly is as guilty as the rest!

If traditional AM broadcasts are declining this is a pity as many first came across radio by building simple Medium Wave receivers. My first introduction to amateur radio was hearing some locals on 160m AM. To many, radio was magic whereas nowadays we take it for granted.

70cm activity contest

Just now (belatedly) I submitted my entry for the 70cm activity contest. 

Because of my poor voice and rubbish set-up (10W and a 2m big-wheel omni antenna) I do not stop on very long. 

If I had stopped longer I would have worked far more than the 2 shown on the map. Usually I work over 100km.

Are the days of the major Japanese manufacturers numbered?


Many people in amateur radio get a lot of pleasure from unpacking a new radio for the first time. 

Often these new radios come with some new feature that a person "must have". Sometimes older radios are traded in to pay for the new box.  In reality, this new feature will not be noticed or rarely used.

Of late, the Chinese, Indians and others have been producing transceivers that are superior at much lower prices. In my view, as the demographic of radio amateurs ages, many of the traditional Japanese manufacturers will think twice or even leave the market.

It would appear that many of these Japanese radios are still using conservative designs. In the past, I think I am right, the Japanese have not been so good on innovation.

Maybe the "big three" are about to get a bloody nose?

Sunshine

 

After what has seemed a long wet and dull period we had a lovely sunny day yesterday. 

This was one of the Cambridge University colleges in the sun.

10m 200mW WSPR (Sunday)

 My beacon was turned on at about 0922z.

UPDATE 0937z:  Two spots of me.

Longest line of sight paths

This came as a real surprise to me. I was expecting the longest line of sight paths on the planet to be around 120km, whereas they are over 500km, which I find almost incredible. 

This was a link on the Amateur radio Weekly email that came yesterday.

Codetalker from AA1TJ




Looking back at my photos from 2009 I came across this innovative circuit by Mike Rainey AA1TJ. It is a voice powered 80m CW transmitter.  Mike has designed some very clever circuits over the years.

10m 5W FT8 (Saturday)


At about 1410z I turned on 10m FT8.

UPDATE 1502z:  57 stations have spotted me and I have spotted 195. See map for those received.

Central Cambridge in the sun

It would seem Cambridge was very popular today, probably as after weeks of rain and dull weather the sun shone! 

There are quite a few bikes in Cambridge!

10m 200mW WSPR TX (Saturday)

 My beacon has been on since about 0945z. 

UPDATE 1440z:   17 spots of me with the best a spot from a station in Brazil.

70cm in the early days


This transverter has been on before, but we forget just how much things have changed in 50 years. I built a version of it to get me active on 70cm. It produced about 100mW AM.   It was used with either a 4el or 8el beam made from PCB material.  Best DX was 160km.

Back then 70cm was almost a frontier band with little commercial gear, so if you wanted something you probably had to build it rather than buy it. Most people (like me!) were fixed on a crystal frequency and people tuned across the band to get a contact. In those days, activity was higher , so you had a much better chance of a QSO. Most contacts were AM.  

70cm SSB? Never heard of it back then!

10m 5W FT8 (Friday)

At about 1440z, I decided to go on 10m FT8 with my QDX-M transceiver. 

Currently I am 10m FT8 RX only.  

On TX it was widely spotted across Europe and North Africa. 

The map shows the stations received at about 1500z.

UPDATE 1848z:  21 stations have spotted me. See map.  Now QRT.


Leper Chapel, Cambridge, UK

This photo was taken from a moving bus earlier this week. The Leper Chapel is the second oldest complete building in the city and dates from the 1100s when it was a hospital.

10m 200mW WSPR TX (Friday)

 My beacon has been on since about 0940z.

UPDATE 1011z: Just EA8BFK (2880km) spotting me

UberSDR


Many people get lots of fun from web SDRs experiencing amateur radio in various locations around the planet. Although I have yet to try it, you can also make your own SDR into a webSDR so others can use it too I believe.

Winter Olympics controversy

A Ukrainian athlete has been banned for wearing a controversial helmet showing people killed in the war with Russia.  Usually sport and politics don't mix. He has made his point.

See https://www.bbc.co.uk/sport/articles/c309pj8d8qqo .

Hopeful signs

Although we are still in the depths of winter in the UK, there are hopeful signs everywhere in nature. 

Snowdrops are out everywhere and daffodils are coming out. Nights are getting lighter and the birds are singing.

Of all the seasons I like spring best of all, but I like this time of year as it is filled with anticipation.

Thursday plans

 Later, I hope to retry 10m 5W FT8 with my QDX-M by QRP Labs.

10m 200mW WSPR (Thursday)

My beacon was turned on just before breakfast,


UPDATE 1525z: 
So far, 15 stations have spotted me. See table.

UPDATE 1618z:  Spotted by 27 stations today.

From the moving bus


This photo was taken yesterday from a bus. It shows the village of Swaffham Bulbeck near Cambridge, UK.

Hot pie


Yesterday we took our elder son to see the flowers at nearby Anglesey Abbey. He was hungry, so we treated  him to a hot pie. We are soft!!

30m WSPR RX (Wednesday)

 My Zachtek receiver is monitoring 30m WSPR.

UPDATE 0911z:  Spotted 5 stations.

10m 200mW WSPR (Wednesday)

 In a very short while I expect to turn on my beacon.

UPDATE 0742z: Beacon switched on at 0730z.

UPDATE 0915z:  No spots.

80m WSPR RX (Tuesday)

 A few minutes ago I QSYed to 80m WSPR RX using the coax to my 2m big-wheel antenna via an ATU.

UPDATE 2107z:   5 Europeans spotted.

UPDATE 2150z:  16 spots of stations. See map by Phil VK7JJ.

Europe as a world power?

Today President Macron made a speech in which he allegedly suggested Europe should act like a world power on the world stage. 

He pointed out that Europe has a population of about 450 million people. It is a stable democracy believing in the world order and international laws.

With the isolationism and breakdown in world order we see now, there is some truth in this.

See https://www.bbc.co.uk/news/articles/ce8n1zdnpd3o .

How much down is my earth-electrode "antenna" in the ground?

Last night I re-looked at how far down my earth-electrode "antenna" in the ground really is. 

At first I thought it was perhaps 1 S point worse on 630m than the coax up to my 2m big-wheel antenna via an ATU. With changing conditions it is really hard to be sure. 

If seems that it is far better than this on the LF bands. It seems to work well on 630m, 160m and 80m falling off as you move to higher frequencies.

Considering how simple and visually great it is (nobody knows it is even there!) I recommend it!

80m WSPR RX (Tuesday)

Whilst on 10m WSPR TX, I realised there is nothing stopping me going on 80m WSPR RX with my Zachtek WSPR RX and my earth-electrode "antenna" in the ground, so at 1135z I turned on 80m WSPR RX.

Rich and privileged

Increasingly, we seem to be moving towards a new world order in which the rich and privileged have power over the common people. 

I have no problem if wealth comes fairly through hard work, but I have a real problem if this came at the expense of others or simply the person was just born into wealth.

I hope this is just a blip and we move to fairness and justice for all.

10m 200mW WSPR TX (Tuesday)

 My beacon was turned on at 1015z.

UPDATE  1046z:   2 stations have spotted me with the best UN7LCJ (4187km).

UPDATE 1201z:  Spotted by 4 stations  with the best HZ1SF (4939km).

UPDATE 1325z:  16 spots of me with 7 from DP0GVN (13685km) in Antarctica with about 10dB in hand!

UPDATE  1611z:  40 stations have spotted me with 10 spots from Antarctica.

Old magazines


Yesterday I came across these magazines which date to around the time I was born. Clearly amateur radio was very popular back then! 

In those days they were A5 size. It would not bother me if radio magazines were that size again. It reduces costs of paper and postage.
