Memo to self, " I must remember 10m WSPR"

Whenever I go on 8m, I forget the 10m antenna is available and that I can go on 10m WSPR TX with my 500mW beacon. Just now I remembered! 

So far, several spots by EA8/DF4UE (2876km).

UPDATE 1822z:  4 unique stations have spotted me today. Two were in Austria and two in the Canary Islands. On PSKreporter one German also spotted me. I am puzzled as I thought everything appeared on WSPRnet. Overall, a pretty miserable day on 10m WSPR.

23cm

This was a band new to me, so a little while back I invested in a transverter from SG Labs in Bulgaria. It is well made and seems to work well. Several people had recommended this 2W transverter.  My idea (when the weather gets better!) is to use it /P from a hill in the RSGB's UKAC activity sessions on 23cm.

Someone very kindly sent me a 3 element yagi, that needs a proper test - thank you so much.

Some people take the band very seriously with high power and big antennas. With these, some incredible distances can be regularly spanned on SSB. As you can tell, I am just "dabbling".  I want to try 23cms without doing much!

Dartmoor ponies - NOT amateur radio

Dartmoor ponies are very famous worldwide. They are wild on the moor and are often seen wandering near the roads. I think this photo was taken in 2012.

Plans for Friday

Later, I expect to go on 40.680 MHz QRP FT8. The Es has started and every day has seen me spotted across Europe with 2.5W and a low wire dipole.

Sunspots - Friday May 12th 2023

Solar flux is 149 and the SSN 152. A=26 and K=2.

Human consciousness - NOT amateur radio

Time and again I am amazed by the things that had to happen for me to be here on this planet, at this time, in this country. I am the result of generations and generations of ancestors. If just one had not existed I would not exist. 

The number of planets in the universe is huge. Some estimate this as 100 billion billion billion billion  The number of planets with sentient life is probably huge. On the Earth now there are around 8 billion humans. Yet I exist.

Exactly what is human life? What exactly is self awareness? Why am I here now, in this country, on this planet? 

Some would say there is a religious element. Whilst I understand this, to me the explanation is too small and too Earth centred.

We always think of time going from the past into the future? Is this an illusion?

Rally this weekend

The following rally in Scotland has been announced. Please check with organisers first to ensure the information is correct.

8m QRP FT8 (Thursday)

It is now 1140z and I have been on 40.680 MHz QRP FT8 for about 50 minutes. So far, one spot from Poland by Es. So far this year 3 countries have spotted me via Es.


UPDATE 1345z:
  3 stations have spotted my QRP 8m FT8 so far today and I have spotted 2. One exchange of FT8 reports was with S77A (1194km).

Thatched cottage - NOT amateur radio

Many of the villages around here have some very attractive thatched cottages like this one.

Last evening on 70cm FT8

As far as I know, conditions last night were normal on 70cm. 

Despite this, 36 stations were copied in the 70cm FT8 activity contest (see map), as far as Germany. And all this was on a 2m omni antenna on RX!  It seems that some sort of troposcatter is possible using FT8. 

Imagine what would have been copied if I had had a typical 70cm beam. If this works at 70cm, what about 23cm or even 13cm? On these bands ERPs of kilowatts are possible with average beams.

No, FT8, has transformed VHF/UHF, making DX possible at any time with very modest stations. If activity was higher people would be making DX QSOs at any time, irrespective of conditions.


Sunspots - Thursday May 11th 2023

Solar flux is 170 and the SSN 154.  A=26 and K=3.

70cm FT8 activity contest


The RSGB activity contest (UKAC) starts at 1900z, but I think the European contest starts earlier.

The map shows the activity on 70cm FT8 well before the UK contest starts! 

My antenna is just a 2m big-wheel omni too!

Ely cathedral - NOT amateur radio

Ely is about 8 miles away "as the crow flies". It is about 12 miles away by road. On top of the hill is the magnificent cathedral that may be seen, like Chartres in France, from miles way. 

At one time, it was surrounded by marshy land hence the name "Isle of Ely".

8m QRP FT8 (Wednesday)

At about 1530z, my 8m FT8 was turned on. I am on 40.680 MHz with a DF of about 1950 Hz TXing in the first period. No spots.

160m QRP FT8 (Tuesday evening)

With SSB bandwidths my noise level on 160m is around S9. On FT8 (50 Hz bandwidth) I have no trouble getting across Europe with 2.5W and my earth-electrode "antenna" in the ground. Last night my CQ calls were answered by stations in France and Germany.

If you have noise issues try FT8 (50 Hz) or WSPR (6 Hz).

Oscar 100 - getting better?


Every few weeks I look at activity levels on the narrowband transponder of this geosynchronous satellite. Most times it is a tail of woe with activity levels far below what I would have expected.  My last peek was at 1410z on a weekday afternoon in Europe.

This time, activity seemed better. In fact, I have never ever seen it busier!

Sunspots - Wednesday May 10th 2023

Solar flux is 180 and the SSN 151. A=14 and K=5.

9 May 2023

160m QRP FT8

For a change, I am on 160m QRP FT8 running 2.5W to my earth-electrode "antenna" in the ground. So far, 6 stations have spotted me with the furthermost ON4RST (371km).

UPDATE 2116z:  12 stations have spotted my 2.5W QRP 160m FT8. (see map).

Frustration - NOT amateur radio

Several times in the last few days I have had to ring about house insurance. After about a minute of time wasting drivel I was asked to say in a few words what my call was about. 

Clearly they were using voice recognition or AI. Without fail my few words were not understood! When asked was I asking about car insurance "is that right?" I replied "no!!".

In the end I was put through to a human being.   I hate AI.  With a poor voice, I am on to a loser every time!!!

10m QRP FT8 (Tuesday)

A few moments ago, I swapped to 10m FT8 instead of WSPR. I am running 2.5W. Both on TX and RX, spots received. Either the band has just woken up or most are now on FT8 rather than WSPR!

UPDATE 1405z:  5 stations have spotted me with the furthermost being 4X1UF (3513km). On RX, all over copied.

UPDATE 1704z:  8 spots of my QRP.

10m Es operation

As we approach the late spring and summer in the northern hemisphere we are entering the Es season. This usually means propagation out to about 1500km is possible on all modes, often with very strong signals. Es is good at any point of the solar cycle at this time of year.

Most days at this time of year 10m and the low VHF bands will open to somewhere. Not every day is good. Some days will be disappointing. Often antennas like CB whips work perfectly well. Usually a few watts is quite enough whatever the mode. 

The simplest antenna is just a low wire dipole, but my Homebase-10 may be useful. It is described on my website. It is essentially a wire halo. It could be scaled for other bands. It is low cost and makes a useful antenna for 10m.

8m QRP WSPR (Tuesday)

For a change, I am on 8m WSPR in the WSPR window just above 40.680 MHz. Yesterday, my 2W 8m WSPR to a low dipole was copied in Germany and Portugal.

UPDATE 1207z:  No spots.

UPDATE 1848z:  About an hour ago, I went back on 8m WSPR. No spots.

70cm activity contest tonight

As this is the second Tuesday in the month, at 1900z tonight should be the 70cm UKAC activity contest organised by the RSGB. 

As I can only run 2.5W to a 2m big-wheel and my voice is poor, I usually stay on for much less than 1 hour. 

As I recall, activity last time was down with many preferring the FT8 activity contest that is usually on the Wednesday. Usually, the activity contest sees SSB activity higher than usual.

10m QRP WSPR TX (Tuesday)

Since about 0800z I have been on 10m WSPR TX with my 500mW beacon.

UPDATE 0842z:  No spots yet.

UPDATE 1208z:  No spots. Bad Es day?

UPDATE 1251z:   Still no spots, so probably swapping to 10m FT8.

The South Hams of Devon


From this picture you can see why I think the South Hams is the best place on Earth. 

V2000 vertical omni

On 6m, 2m (vertical) and 70cm (vertical) the V2000 is used. This photo was taken some years ago. On 6m with 1W CW the USA has been worked with this antenna. 

Sunspots - Tuesday May 9th 2023

Solar flux is 172 and the SSN 103.  A=16 and K=2.

8 May 2023

10m QRP WSPR TX (Monday)

When on 8m, I keep forgetting that my 10m antenna is free and I can go on 10m 500mW WSPR TX with my beacon. 10m WSPR QRP TX was turned on at about 1530z.

UPDATE 1545z:  Widespread reports by Es of my 500mW 10m WSPR TX now being received. Some reports suggest just uWs would be sufficient! This suggests widespread reception by Es of unlicenced 8m ISM WSPR beacons.


UPDATE 1842z:
27 unique stations spotted my 10m 500mW WSPR beacon in just a few hours. Es is definitely back. It is still on TX. Furthermost was TA4/G8SCU (3010km).

The future of amateur radio

This is a subject I have discussed before. These are my current views. I may well be proved wrong.

  • National authorities like OFCOM and the FCC gain nothing from amateur radio and have no real interest.
  • In 20 years' time most of the people currently active in amateur radio will be dead.
  • In the future, all amateur radio will be run by national radio societies like the RSGB and ARRL who will allocate callsigns for those that still want them.
  • Exams will not be needed. Who needs exams to talk about gardening on 80m with commercial gear?
  • Deregulated services like ISM and CB will merge with a deregulated amateur radio service.
  • There will be fewer dedicated amateur radio products.
  • There will be fewer, and smaller amateur radio magazines.

Amateur radio as a service is changing. In my view, the future is about deregulation and as long as you don't interfere with others, it may be allowed. Access to all (current) amateur bands will be open to all.

Does it bother me? Not really. Experimenters will continue to experiment and those that want to natter about gardening can just get on with it. 

Cynic, me?


Mr Putin, what are you hoping to achieve? - NOT amateur radio

The "special operation" by Russia against Ukraine is now in its second year. At one time the Ukrainian people had a certain respect for Russia. Indeed many in both nations have relatives in the other country. All respect by the Ukrainian people for Russia has gone. The Ukrainian people HATE Russia.

In my view, this war/invasion is totally and utterly stupid. What good can ever come of this? Every country has the right to determine its own future. By free and fair elections the people can choose their own future without external interference.  I sincerely hope peace can be created. 

See https://www.bbc.co.uk/news/world-europe-65524104 .

New page on website


For the last month or so, I have been having great fun using my tiny QDX digital transceiver from QRP Labs.  I am amazed that something this tiny works so well. If is so much smaller than my other rigs!  A webpage has been created. 

Mine is the version covering 20m to 10m. Other versions are available.

Just imagine a good multi-band transceiver with case with change for less than $100. Every amateur home should have one! If your soldering skills are normal this should be a straightforward build.

8m QRP FT8

My gear (2.5W and a low dipole) was turned on at 0810z. In the last few days I have been spotted on every day without any Es DX and I spotted a newcomer to 8m G3WCS in IO83 square.

I just wish the RSGB and OFCOM would see the value of a very narrow band around 40.680 MHz by NoV for the Amateur Radio Service instead of both being so "anti".  5kHz would be so useful for research. Instead, we have to pay to do useful research!! Madness. 

Sorry, I have no sympathy with this position. Yes, I know weather radar may use some of these frequencies, but I gather these are at night to minimise interference to/from other services. The ISM band is protected by limits and international law. The RSGB should be actively fighting for us on our behalf. Instead, they seem to be meekly accepting OFCOM's position rather than causing a fuss. Yes, protect our existing bands by all means (personally I would prefer more, narrower bands BTW), but please understand that some of us wish to contribute to genuine research and not talk on 80m with commercial gear about growing carrots . Rant over.

Keeping within the law, I hope as many as possible will operate legally within the 8m ISM allocation 40.66-40.70 MHz with WSPR or FT8 beacons without a licence.

UPDATE 0834z:  No spots.

UPDATE 1258z:   Just G3WCS (223km) spotted on RX. No spots of me on 8m FT8 TX.

UPDATE 1437z:  No 8m FT8 spots of me today so far. Disappointing.

UPDATE 1450z:   At last!  Some Es with a spot of me by HC02 (1808km) in Portugal. Thank you Hugh.


UPDATE 1557z: 
Spotted in 5 EU countries so far today on 8m FT8. It took a while, but Es is definitely here!


UPDATE 1820z: 
Just did a series of 8m WSPR tests with HC02 in Portugal, gradually dropping power to 50mW. probably 10dB in hand suggesting 10mW ERP in the ISM band will definitely be widely spotted in Europe.

Plans for today

Later, I intend to go on 8m QRP FT8. As yet, I have not seen any Es. This is late. 

Wisdom - NOT amateur radio

Back in the 1960s, I was invited by a friend to a Billy Graham crusade, that was televised to a cinema in Plymouth. Evangelical Christianity was not for me, but one thing has stuck with me to this very day. This was the difference between being clever and being wise. Many are clever, but not many are wise. My Auntie Kitty was not clever, but she was wise.

Some people are graced with wisdom. They can see beyond the obvious and discern what lies beyond. They have an inner sense of the ultimate truth that lies beyond the surface. These people have real wisdom.

The ultimate message is you do not have to be clever to be wise.

Wisdom is a gift. 

Sunspots - Monday May 8th 2023

8m access without a licence

Following correspondence with OFCOM here in the UK, it is my view that anyone at all may use the 8m ISM band 40.66 - 40.70 MHz for beacons without a licence as long as they comply with the technical requirements and IR2030. In the UK this means 10mW ERP . 

At times this will cross Europe on WSPR, possibly even on FT8. In your own country, rules may be different. If you are unhappy, seek your own legal advice as I am not a legal expert. In the UK callsigns and locators are not required by law in the ISM bands, but I advice using a callsign and QTH locator that can be reported on WSPRnet.

What this could mean is many more stations beaconing on 8m.

This is NOT the Amateur Radio Service. 

As I see it, it is a legal way to do experiments and research on 8m.


Where is this? - NOT amateur radio


This photo was taken 7 years ago. It is almost certainly somewhere in East Anglia, although I cannot recall where. If you recognise it, please put me out of my misery!

Bellringing bonkers - NOT amateur radio


One of our grandsons is totally mad on bellringing.  At the last count he had run in 109 places!. This video shows him ringing nearby. I think he is doing a full peel somewhere this weekend. This takes several hours.

Changes

When I was first involved with amateur radio it was 1962. 

My first venture into radio was when my dad bought me a Heathkit Electronics Workshop for Christmas 1961. This allowed you to make a variety of circuits without soldering. That first Christmas I was DXing on Medium Wave. I joined the RSGB shortly afterwards. My first G8 call was in 1966 and I became a G3 in 1967, taking my Morse test in the famous Liver building in Liverpool.

My first serious TX activity was when I moved to Cambridge in the early 1970s. My first outings were on 2m AM, then 70cm AM with a simple homemade QRP transverter. In those days most people were crystal controlled, so it was "tuning high to low" to get a contact.

These days, people rarely come on just for a chat. Times are changing.


My 2m-70cm transverter was based on this circuit in the old "VHF Communication" magazine. It produced  about 100mW on 70cm. From a local hill you could almost guarantee a QSO with this in the 1970s.

OFCOM updates

A reminder that OFCOM updates the information it hold on licences etc. every week. See the OFCOM website for the latest data. 

Incidentally, I enquired about changes to my T&I 8m licence. A month later, I am still awaiting a response. They say they are incredibly busy. At this rate, the Es season will be over before they respond!  I know from work days how this can feel, but a response email would take just a few minutes!
