630m WSPR RX (Sunday)

At 1046z I QSYed to 630m WSPR RX. I am not sure how many people are on during the day, so this is an experiment.

UPDATE 1120z: PA3GSH (396km) spotted. It would appear his signal is right on the edge of being copied.

UPDATE 1138z: G0VQH is getting signals far stronger than I am on 630m WSPR. I am not sure what Jennie is using, but it certainly works better than my system currently!

UPDATE 2130z: Went back on 630m WSPR RX for the evening. 3 stations spotted. QRT soon.

10m FT8 RX (Sunday)


At the moment, I am on 10m FT8 RX. At 1014z (must always remember that in the UK we are now British Summer Time!) 388 stations spotted as the map shows. It is too easy! 

UPDATE 1038z:  501 stations spotted.

I might QSY to 630m WSPR RX soon.

Sunday plans

Getting the optical gear working 

As today looks dull and wet, these are my plans :

  • Email G4BAO to set up a sked on 23cm SSB.  Email written and sent.
  • Try to get the optical gear working. All gear assembled. Spectran installed. 
  • Go on 10m FT8 daytime. RX on morning. Off late morning.
  • Go on 630m WSPR RX this evening. Went on late morning. 
Doing anything these days is so much harder. After getting my 481 THz gear together I feel exhausted. I cannot remember how I interfaced from the optical RX to the PC. I must find out. It was 10 years ago!!

I may try a local CW test after dark this evening bouncing off a wall about 200m away - small steps.

The other Burwell - NOT amateur radio


We live in Burwell in Cambridgeshire. There is another Burwell in Lincolnshire that is much smaller. It is shown in the photo 

Sunspots - Sunday March 26th 2023

Solar flux is 160 and the SSN 105.  A=15 and K=2.

Magnolia - NOT amateur radio

 


Magnolias in bloom are a sure sign of spring. We saw this in the nearby village of Lode. There were at least three.

630m WSPR RX (Saturday)


Rather earlier than normal, I have turned on 630m WSPR RX. So far spotted PA3GSH (396km), so my system is working. 

Again my "antenna" is the coax to my 2m big-wheel omni antenna tuned with a ferrite rod on the bench.

UPDATE 1930z: 2 stations spotted so far this evening with the furthermost DB8BG (498km).

UPDATE 2220z: 
QRT soon. 6 stations spotted this evening. Furthermost was SM6BGP (981km).

Progress

About a week ago, I outlined the projects that I hoped to tackle in the next 4 weeks. So far, I am making progress. 

  • My FT-710 now works with FT8 .
  • I have had a QSO on 4m FT8, albeit with my 2m big-wheel and coax via the auto-ATU in the FT-710.

Next week, I hope to re set up my optical gear and do some local tests and arrange a 23cm SSB sked with G4BAO

Progress!

10m QRP FT8 (Saturday)

At the moment, I am on 10m FT8. So far, 3 stations have spotted me after about 5 minutes and 5 stations have been spotted on RX.

UPDATE 1152z:  6 stations have spotted me today so far with the furthermost RA9CIN (3701km). On 10m FT8 RX 78 stations as the map shows.

UPDATE 1225z:  12 stations have spotted me, 1 QSO and 123 stations have been spotted on 10m FT8 RX.

Spots of my QRP 10m FT8 today

UPDATE 1725z:
354 stations spotted on RX and 18 spots of me today on 10m FT8 QRP TX.

Lincoln 2013 - NOT amateur radio



In 2013, we visited Lincoln. It was very cold! The photo shows Lincoln Cathedral proudly on the hill. 

Sunspots - Saturday March 25th 2023

 Solar flux is 158 and the SSN 108. A=66 and K=2.

24 Mar 2023

630m WSPR RX (Friday)

At 1850z my 630m WSPR RX was turned on. No spots yet.

UPDATE 2206z:   Still no spots.

UPDATE 2208z:   I am puzzled. G6AVK is usually copied, but I have had no spots all evening. As far as I can tell, everything is correct. It is not just uploading to WSPRnet as there are no local spots either!

UPDATE 2240z : Restarted WSJT-X and immediately got spots from the Netherlands and Germany. Not sure what was going on. Now QRT. 


Another banking crisis? - NOT amateur radio

Although the banking sector is supposed to be far more resilient these days, you could be forgiven for thinking otherwise. Bank stocks still look spooked by recent events with SVB and Credit Swisse. I hope this is short lived.

10m FT8 (Friday)

Am now on 10m FT8. Only D2UY (Angola) coming through, suggesting there is plenty of disturbance. I am not sure if there is a delay on PSKreporter at the moment.

UPDATE 1456z: Just 2 G spots of me so far. These are probably normal tropo. Furthermost is G4FAL (180km) near Sheffield. I remember that this sort of range was always possible with QRP 10m SSB and a dipole. It is probably even more likely with FT8. Pretty sure far more inter-G QSOs would be possible on 10m FT8.

UPDATE 1900z:   Now QRT, but in the end I was spotted by 8 stations and I spotted 12.

CDARC Zoom talks

As I am unable to drive at night, I have really enjoyed the Cambridge  Radio Club lectures via Zoom. They are trying to arrange "hybrid" meetings with personal contact in Cambridge and Zoom lectures for those that cannot get in. In my view, the Zoom lectures have been excellent.

My personal view is that all lectures should be on Zoom only, with a social gathering somewhere else once a month. This would mean no room hire, reduced annual fees, people could watch or talk from anywhere on the planet and people could watch the Zoom talks with others in their homes if they do not have Zoom. I would expect most people have Zoom.

Imagine if CDARC became a worldwide radio club!

The image is from the CDARC website. I wanted to link to this image, but could not see how to do this. Instead, I took a screenshot. If copyright infringement is an issue, it will be removed.

Grass cutting - NOT amateur radio


For the second time this year, I cut the grass, just beating the rain. February was very dry, but March made up for it!! 

4m FT8 (Friday)

 As HF looks to be disturbed, I am again on 4m FT8 with my makeshift antenna. At 1043z, no spots.

UPDATE 1245z:  No spots of me, but G4HGI (244km) spotted on 4m FT8 RX.

UPDATE 1416z: GW8ASA (301km) has again spotted me at similar levels to yesterday.

UPDATE 1421z: Nothing outside of the UK so far on 4m FT8. Rather surprised there are not many more stations on 4m FT8. I expect this will change in the Es season.

Lightning

One of the pleasures of UK winter is the usual absence of thunder and lightning. In the UK they can occur, but they are far more common in the summer. 

Although I know the chances of a direct strike are low, they do occur. I know of 2 friends who had this. One of the more common things is a power surge as storms approach.

What I tend to do is keep a watchful eye on approaching storms. If there is any danger, I disconnect everything: antennas, mains plugs etc.. I have no idea if this is the correct strategy. My view is it is better to be safe than sorry.

See https://sites.google.com/view/g3xbm4/home/other-amateur-radio/lightning-maps .

CME

It looks like the coming days (especially today) could see quite disturbed solar conditions due to a coronal mass ejection (CME) on the sun. I am not clever enough to know how this will effect HF and low VHF.

See https://www.solen.info/solar/ .

Red Kites (birds) - NOT amateur radio


Until these birds were re-introduced in England some years ago, you would only see them normally in Wales. Now they are a quite common sight especially near motorways where they seek out road kill.

See https://www.rspb.org.uk/birds-and-wildlife/wildlife-guides/bird-a-z/red-kite.

Sunspots - Friday March 24th 2023

Solar flux is 151 and the SSN 73. A=60 and K=7. Disturbed!!

Low cost RF modules


A few moments ago I took a peek at RF modules on eBay. This is just one that will cover many bands. Someone much fitter than me could probably design some useful kit around these.

Signs of spring?


In the UK, clocks go forward an hour on Sunday morning to British Summer Time (BST). Already there are promises of better days to come. Weeping willow trees often have hints of green before most others. This one in Ely a few days ago thinks it is spring!

I like the spring as it is the season of new hope after a long, dark winter. The blossom does not last long, but it beautiful for a while. I prefer the spring to the summer.

Under water - NOT amateur radio

 


These were photographed by a friend earlier this week in Letchworth.

Unused spectrum - NOT amateur radio

OFCOM is consulting on the future use of the 1900-1920 MHz spectrum. See the OFCOM website for details. Apparently these frequencies are allocated, but not used. 

4m FT8

 At the moment I am again on 70.154 MHz FT8 with my big-wheel 2m omni and coax tuned via the auto-ATU in the FT-710.  At 1029z, no spots. I have yet to be spotted on 4m, although my "antenna" does not help!

UPDATE 1226z: Well, my 4m "antenna" is working with 3 stations spotted and one spotting me - G4HGI (244km). 

UPDATE  1241z: I would imagine that most propagation is one of the following: flat-band propagation, tropo enhancement, MS or scatter. As Bas says in the comments, the Es season is probably some months away still.


UPDATE 1515z: 
G3SHK (200km) has been spotted, and has spotted me, on 4m FT8 (see map).  M0RJV (91km) has spotted me.  Still to have my first FT8 QSO on 4m. The impression I am left with is this band is very under-used apart from (maybe?) during the Es season.

UPDATE 1630z:   My first ever 4m FT8 QSO has happened. GW8ASA (301km) was worked this afternoon using the 8m dipole and the internal auto ATU.


Stations spotting me
today on 4m FT8 TX

UPDATE 1907z:
   No further stations spotted.

UPDATE 2115z:   QRT.

Devon cliffs - NOT amateur radio


This photo was taken in 2012 and shows me in Bolberry Down in Devon.

Sunspots - Thursday March 23rd 2023

Solar flux is 159 and the SSN 81. A=17 and K=1.

630m WSPR RX

At 2005z, I went on to 630m WSPR RX using the 2m big-wheel and coax via a ferrite rod ATU. So far this evening, a couple of German stations spotted.

UPDATE 2119z:  G6AVK (78km) also spotted. 

UPDATE 2218z: Now QRT.

Ely Cathedral - NOT amateur radio


This photo was taken yesterday at Ely Cathedral. There has been Christian worship on this site for 1350 years. 

Electric cars - NOT amateur radio

In a few years, as mentioned recently, I am expecting a "tipping point" when most use electric cars rather than cars fuelled by fossil fuels. My prediction is this will happen about 2028. 

For this to happen, range has to be considerably improved and prices have to fall dramatically. Electric cars today appeal mainly to early adopters, those who feel strongly against fossil fuels and those who only make very short journeys like shopping trips and who can charge at home.  I think the breakthrough will come with solid state batteries.

Usually on my trips to Cambridge I see about 2 electric cars. Today I saw 10!! There must be a lot of early adopters!

10m FT8 QRP (Wednesday)

As I am back from Cambridge, I am on 10m QRP FT8 with 5W.  After about 10 minutes,  13 stations have spotted me and I have spotted 99.

UPDATE 1540z:  28 stations have spotted my QRP 10m FT8 and I have spotted 257.

Stations that have spotted my
5W 10m FT8 today at 1800z
UPDATE 1945z:   572 stations have been spotted and 80 stations have spotted my 5W 10m FT8 TX.

AI search engines - NOT amateur radio

There has been a lot recently about artificial intelligence and search engines. First there was ChatGPT followed by GPT-4 and now BARD which is Google's experimental version.

I can see great danger with these as people believe what these bots create as truth, when it may be full of errors. I tried BARD out and most was correct, but some things were totally wrong!! 

Sunspots - Wednesday March 22nd 2023

 Solar flux is 152 and the SSN 70. A=8 and K=3

Thatched cottage - NOT amateur radio

 


The photo was taken in 2013. It shows a thatched cottage in a village not far from here.

630m WSPR RX (Tuesday)

At about 1745z, I changed to 630m WSPR RX. It is now 1756z and, so far,  no spots.

UPDATE 2057z:   2 stations spotted so far this evening.

UPDATE 2240z: Now QRT. 

4m UKAC - missed it!!

Last Thursday evening was the 4m (70 MHz) activity contest for March. I missed it! 

My antenna is just my 2m big-wheel and coax matched via the auto-ATU in the FT-710. I have no idea how it performs with regard to gain, polarisation, or directivity. This I was hoping to find out! Maybe in April? My next chance looks like April 20th.

Birthday lunch - NOT amateur radio


Yesterday we went to lunch with old university friends we have known since the 1960s. Seeing them, it is as if we had seen them just the day before. 

10m WSPR QRP TX and RX

 At present, I am on QRP 10m WSPR using the FT-710. After the first transmission 4 spots.

UPDATE 1625z:  My own 5W WSPR TX has been spotted by 19 unique stations and I have spotted 135 unique stations. Furthermost so far is a spot by WP3SM (6851km) in Puerto Rico.

Tuesday plans

My current plan is to go on 10m WSPR with the FT-710 to see if I can preset the optimum settings for WSPR. I may try 630m WSPR RX after dark.
