Sunspots - Saturday December 13th

Solar  flux is 135 and the SSN 124. A=28 and K=2.

A good use of AI

AI frequently gets a bad press, but there are some things it is very good at. 

Today I chanced upon a movie on YouTube of London in the 1700s. It was created using old black and white prints from that time. 

The finished movie gives you a great impression of how it must have been.

Geminid meteor shower

This meteor shower peaks this weekend. I expect it will lead to enhanced MS propagation on 10m, 8m, 6m, 4m and 2m. 

See Geminid meteor shower.

8m FT8 RX (Friday)

 All day I am on 8m FT8 RX.

UPDATE 1802z:  No spots.

Sunspots - Friday December 12th

 Solar flux is 146 and the SSN 123. A=26 and K=4.

Royal Ballet

It is fair to say that our granddaughter did NOT get her talent for ballet from my wife and I!! 

Last year she performed in front of UK royalty in Westminster Abbey and this year she is in the Nutcracker at the Royal Ballet in Covent Garden, London at the Royal Opera House. She makes us very proud!

10m 500mW WSPR (Thursday)

 My beacon was turned on at 1248z.

UPDATE 1318z: So far, no spots. 

UPDATE 1328z:  It helps if there is power connected. Being suspicious I noticed the power wire had become disconnected!

UPDATE 1353z:  Spots from the Canary Isles only.

UPDATE 1827z: 4 stations have spotted me including 2 in the USA. Now QRT.

Ukraine peace?

 According to this video, around 60% of people in the USA believe the USA should be standing behind (my understanding) Ukraine to counter the Russians whereas the peace plan put forward by President Trump appears to favour Russia and not what the majority in the USA want.

We all want peace, but it would appear we don't want a sell-out to President Putin. In my view simply appeasing Putin is not the answer.

From an outsider's perspective, President Trump seems more focused on making deals to make himself even richer than safeguarding democracy? This is how it appears, although I accept I may be wrong.

Micro80

This was my Micro80 transceiver  built many years ago. From this the famous Pixie transceiver was developed. It is on my main website.

Sunspots - Thursday December 11th

 Solar flux is 168 and the SSN 134. A=23 and K=4.

6m CW DX

 My best ever 2-way 6m DX was a QRP CW QSO with K1TOL when I was using 1W and a V2000 vertical omni antenna. This was Es. I think his antenna helped!!

Pure evil

In recent days I have been watching a series of programmes on the history of the British Empire. What comes across is how evil Britain was. I cannot believe how bad we were. 

The real purpose of the British Empire seems to have been exploitation.  We are in no way able to dictate how other countries should behave when we have been so bad in the past, and even quite recently.

Hair!!

 Back in the 1970s I still had hair! This is me using my 2m AM Fredbox to make contacts in Cambridge. It worked really well.

10m 500mW WSPR (Wednesday)

My stand-alone W5OLF (SK) 10m WSPR beacon has been on since about 0930z.

UPDATE 1515z:  23 stations spotting me. See WSPR Rocks map.

Maps in your head?

People have different ways of remembering .  When I am awake at night one strategy I use is to travel from A to B using the map in my head. I am surprised how many places are in my head!! For example places where I have lived or worked.

Sunspots - Wednesday December 10th

 Solar flux is 183 and the SSN 134.  A=5 and K=3.

QRP Fun

This video is 7 years old, but it might inspire you. Basically it is a 1 transistor transceiver by Dave Ingram K4TWJ from the book "International QRP Collection". 

I would expect the RX to be deaf so probably best to use on a sked rather than calling CQ on a frequency already occupied by a station that you cannot hear.

6m 5W FT8 (Tuesday)

My gear was turned on at about 1053z.

UPDATE 1409z:  So far, 8 British Isles stations spotting me. See map.

UPDATE 1936z: 11 stations have spotted me. See logbook. QRT soon.

10m 500mW WSPR (Tuesday)

My beacon was turned on at about 1052z.  

UPDATE 1411z:   Spotted by 15 stations. See table.

UPDATE 1518z: Spotted by 18 stations now.

More on Sable Island DXpedition

The dates for this are expected to be March 19-31 2026. I imagine the pile-ups will be massive! I hope to hear them, but my days of chasing DX are gone! I am not sure what modes or bands they plan.

See https://t-rexsoftware.com/cy0s/

OFCOM and satellites

Today OFCOM announced its final decisions about direct to smartphone communication via satellites. This could allow ordinary smartphones to use satellites to communicate giving coverage at sea and in very remote areas. Currently this needs special satellite phones.  I am not sure what antennas will be needed as special satellite phones currently have bulky antennas.

How this develops remains to be seen.

Tuesday plans

 Today I expect to go on 10m 500mW WSPR and 6m 5W FT8.

AD and BC

Has the world gone stupid?  

The "politically correct" phrases are now BCE and CE (common era).  Whether we believe in Jesus Christ or are of some other faith or none, why the heck change it?  

In my view this political correctness gone mad.

Sunspots - Tuesday December 9th

 Solar flux is 186 and the SSN 146.  A=2 and K=0.

Sable Island 2026 DXpedition

Sable Island is a small island of shifting sands in the North Atlantic belonging to Canada. There is a DXpediton there in 2026. I think there are no people permanently living there. 

There are wild horses there. It is continually changing shape.

See https://parks.canada.ca/pn-np/ns/sable .

Change of plan

 In the end I decided to go on 10m 500mW WSPR TX. 10 stations have spotted me 6 of which were in the USA.

UPDATE 2010z:  Spotted by 12 stations. Now QRT.

zBITX

 You may like this transceiver from India. For the price it is remarkable. It is built around a Raspberry Pi.

Monday plans - no radio?

 As we have to go into Cambridge for some Christmas shopping, I may not go on the radio today.

Museum at Christmas

This weekend, our local museum had a "Santa's Grotto" in the windmill. The children loved it and were told a story (in groups) and were each given a gift. To them it was magical.

In the main museum, there was face painting, mulled wine, minced pies  and much more. We helped with the raffle.

In all, it was a great. happy, occasion for all, especially the children.

Sunspots - Monday December 8th

 Solar flux is 194 and the SSN is 133. A=8 and K=0.

10m 500mW WSPR (Sunday)

My beacon has been on since about 1115z.

UPDATE 1607z:  12 stations have spotted me. See table.

UPDATE 2138z: QRT

6m 5W FT8 (Sunday)

My gear was turned on at about 1115z.

UPDATE  1132z:  Spotted by 2 English stations.

UPDATE  1603z:   13 stations have spotted me. See map.

UPDATE 2140z:  18 stations spotted QRT.

That time of year!

The museum and windmill near us is having a Santa’s Grotto weekend. 

We’re helping today.

Sunday plans

 Probably 500mW 10m WSPR and 5W 6m FT8 later.

WSPR?

The impression I am getting is that WSPR is going down in popularity whereas FT8 is going up. I was considering buying a dedicated multi-band WSPR TX and WSPR RX.  I am having second thoughts.

WSPR needs less bandwidth (about 6Hz) than FT8 (about 50Hz) but WSPR is more sensitive by about 10dB. Maybe many cannot make use of this because of local noise. Also FT8 allows 2-way QSOs.

Last evening I tried 40m WSPR  and FT8. On WSPR I spotted nobody, whereas on FT8 I spotted 12 stations in a similar period.

Sunspots - Sunday December 7th

Solar  flux is 200 and the SSN 129. A=16 and K=3.

AI crappery

At one time I enjoyed YouTube, but sadly you no longer can be sure that anything is real. 

I watched a very long video supposed to be by Brian Cox. It was clearly not by Brian Cox. Last week I watched a video that was meant to be the thoughts of Einstein.

The message is clear: you cannot know what is real and what is AI. The only thing you can do is assume everything is generated by AI unless you can be absolutely certain of the source.

Is there a universe?

This is a philosophical question. 

Is there any way of proving anything exists outside of ourselves? 

We observe everything through our senses and neurons. What happens when these are no more?  Does the world and universe still exist or is it only there because we observe it?

Ralph Waldo Emerson quote

" Do not go where the path may lead, go instead where there is no path and leave a trail."

This was a quote I cam across earlier from Ralph Waldo Emerson.

ZachTek WSPR transmitter

These are handmade in Sweden, although there is a Chinese rip-off that is available for much less. I think if files are available on the internet there is always a danger of this happening. 

I am not sure what protection registering the design gives, but I guess it must offer some help.

As I understand things, the Chinese rip-off does NOT contain switchable low pass filters, so the harmonic output is unlikely to be very good.

See https://www.zachtek.com/product-page/wspr-desktop-transmitter 

Saturday plans

 Probably 10m 500mW WSPR and 6m 5W FT8, although I am not sure.

Sunspots - Saturday December 6th

 Solar  flux is 206 and the SSN 133.  A=13 and K=4.

Oscar 100

MLS, one of the large UK distributors, is selling the DX Patrol Ground Staion for QO-100. I guess you have to add a GPS external reference, a LNB, a dish and a TX antenna.  

Probably you would still get change from £2k, which is less than the cost of many HF transceivers, a linear and a beam on a tower plus rotator. I guess operators now have confidence in this after many years.

The advantages are many.  The dish is small, fixed and no HF rig is needed. Within the footprint of the satellite DX is always available and without QSB. In many ways I am quite surprised many DXers have not gone for this option already.

I prefer experimentation.

See https://eshail.batc.org.uk/nb/ if you want to take a peek.

Incidentally, I heard recently about someone in the UK working a German station who was mobile on Oscar 100!! I think the station in the car was listening on the webSDR but using the 2.3GHz uplink to the satellite.

I suppose a low(er) cost option is to make or buy a TX transverter and helix and listen on the webSDR.

10m 2W FT8 (Friday)

My gear was turned on at about 1245z 

UPDATE 1330z: So far, 59 stations have spotted me. 

Really low cost kit

Steve G1KQH has brought to my attention a very low cost SSB/CW 40m kit from India. It really is exceptional value. 

As a club project you can even buy 5 kits (yes five kits!!) for $150 total. Individual kits are just $39.

See www.hfsignals.com  .

Friday plans

 Probably I shall go on 10m 2W FT8 later.

Dark breakfast!

In the UK early mornings are dark. Our grandson stays with us on Thursday night as he has an early start on Friday and relies on me to get him up although so far he has been very good for an 18 year old. Thankfully things get better after Christmas.

Sunspots- Friday December 5th

 Solar flux is 220 and the SSN 165. A=32 and K=3.

10m 2W FT8 (Thursday)

 

At about 1830z I QSYed from 8m and instead went on 10m FT8 with 2W. 

UPDATE  2021z:  10 stations have spotted me with the best PU2YFR (9602km). Now QRT.

Future plans

Already, I am thinking about 2026. Sunspots and solar activity should still be good although declining. 

My instincts are to go mainly on 10m QRP FT8, although I shall go on 6m FT8 in which case I shall go on 10m WSPR wth my 500mW beacon that does not need the PC at the same time. 

Still tempted by 8m, TX,  although I think most of the activity would be in the Es season. If I was to reapply for a TX permit, I would time it to coincide with the Es season, so leave any new application until late March, so the permit would be in place in time for the Es season. I may decide not to bother.
