630m QRP WSPR (Saturday)

My 10mW ERP was turned on just before 1900z. Already several spots of me at 1910z.

UPDATE 1930z: According to PSK Reporter, I am currently the only UK station on 630m WSPR TX! 4 stations have spotted me so far this evening.

UPDATE 2010z:  6 stations have spotted me this evening.

Dark evenings - NOT amateur radio

It suddenly seems to be dark early. Only a few months ago it was much lighter at this time. 

Here we are at 1625z with the curtains drawn in "winter mode". In a few weeks it will stop getting darker and gradually lighter, although it is the end of January before we really notice things changing. 

I like the seasons. There is something good about them all.

70cm QRP FT8 (Saturday)

At about 1610z I QSYed to 70cm FT8 with my 2.5W and the 2m big-wheel omni antenna. No spots.

UPDATE 1914z:  No spots, so have QSYed to 630m QRP WSPR.

10m 500mW WSPR TX


As I am on 2m FT8, I can use my 10m WSPR TX beacon. 

UPDATE 1508z: 
 So far, I have been spotted by 28 stations on 10m QRP WSPR.

UPDATE 1513z: I have turned off the PA in my beacon. Even though it will report as 0.5W (programmed in), the actual output is 0.5mW (500uW).

UPDATE 1600z:  No spots since turning PA off.

2m 2.5W FT8

My 2.5W FT8 (using the big-wheel omni antenna) is now on 2m 144.174 MHz. So far 11 stations have spotted me.

G0LRD
has a monitor (see attached). This is about 25km away and is a good check that things are working and the signal is clean.

UPDATE 1422z: 19 stations in 5 countries have spotted my QRP signal on 2m FT8 today with the furthermost GI6ATZ (479km). See map. This is too easy too!

UPDATE 1528z: Interesting that I am only spotting 5 UK stations. My RX is working properly, so this suggests low activity.

New challenge needed

HF bands present no real challenge. Recent microwatt tests on 10m WSPR have been fun, but I need a new challenge. 

My 2.5W 8m FT8 signal has been received in most of the places I had hoped for, and this is not likely to change until there are a few new countries on the band. At the moment I am inclined to ask for a new 8m permit from April 2024 - April 2025 even though I have to pay to do research, which I find utterly stupid!

Later today, I may QSY to a VHF band FT8 as this is "different" and not something I have tried for a while.

8m going "off the boil"?

In recent days, 8m seems to have lost its attraction a bit. 

The FCC does not want to renew access to the band to USA stations and F2 has probably peaked for now. The main Es season in the northern hemisphere is long over and even 6m has been good for F2 DX.  At the moment, I have moved down to 10m FT8, although this is really no challenge.

We could definitely do with more countries legally TXing on the 8m band.  Even just CW, FT8 and WSPR only at low power 40.680 - 40.685 MHz would be a start. As this would be within the ISM band I cannot see this should be a problem.

Wet King's College, Cambridge - NOT amateur radio

 

My wife took this photo last Tuesday. We missed most of the rain. This is the path up to King's.

How efficient is my earth-electrode "antenna" in the ground on 630m?

My best comparison is with Jason M0NYW who is using the same G3XBM transverter, but I believe a more conventional antenna. He is also reporting his ERP as 10mW. Jason gets better results that me. In the last 12 hours he was spotted by 39 stations, whereas I was spotted by 16.

How much difference is there? Clearly, he is getting better results, so his antenna and ground are better. Most of my reports are quite close to the limit. Also, for some stations, the local noise can put a stop to very weak signals being decoded. When near the limit of decode, a few dB could make a great deal of difference.

So, it is very hard to say how much better Jason's system is than mine.

All I can say is a more conventional setup is better. What I can say is the earth-electrode "antenna" in the ground does work and is just about invisible.

10m QRP FT8 (Saturday)

 My 2.5W 10m FT8 was turned on about 0915z. So far, 10 spots of me by what looks like single hop F2. For some reason PSK reporter was not reporting my spots. I have restarted WSPR-X. Since restarting, I am getting spots from all over the world appearing on PSKr.porter.

UPDATE 0950z:  My 10m QRP FT8  has been spotted by 26 stations and 82 stations spotted here.

UPDATE 1012z: 43 stations have spotted my 2.5W 10m FT8 with the furthermost VK8DNT (13807km). 135 stations have been spotted here.  At the moment, 10m really is too easy.

UPDATE 1033z:   57 stations have spotted my 2.5W and 175 stations have been spotted here.

Sunspots - Saturday November 18th 2023

 Solar flux is 120 and the SSN 26. A=3 and K=1.

630m QRP WSPR (Friday)

My 10mW ERP from the earth-electrode "antenna" in the ground was turned on about 1855z. So far, 2 UK stations have spotted me.

Black Friday "deals" - NOT amateur radio

In recent years we have seen this import from the USA. I think the original idea was to make consumers buy things over a longer period. Just now I looked on the Asus website for deals and, quite frankly, I think consumers are being taken for a ride.

As a "boring old fart" (BOF) I think this whole "Black Friday" thing is stupid, and this is one more import from the USA that they can willingly have back. 

I am sure it is aimed more at the seller than the consumer. Retail outlets are having a hard time and their business models have to change to compete with online sellers.

However, Black Friday is one innovation we can do without.

Leonid meteor shower

This peaks about now. I have no idea how good it is as an MS propagation mode. What usually happens is the trail causes ionisation that reflects VHF signals.

10m QRP FT8 (Friday)

 As 8m was poor, I have QSYed to 10m FT8 with 2.5W and my end-fed antenna. The switch was made at 1506z.

UPDATE 1527z:  5 stations have spotted me and I have spotted 112 stations already.


UPDATE 1655z: 
35 stations have spotted me and I have spotted 443 stations.

UPDATE 1830z: 
 614 stations have been spotted here on 10m FT8 RX.

8m QRP FT8 (Friday)

My 2.5W was turned on at about 1400z. No spots. 

Rural England - NOT amateur radio


Many think of England as a crowded country, but there are plenty of very nice places. As an example, this is the village of Lode near Cambridge. This is the village cricket green.

630m WSPR (Friday AM)


Probably for the morning, I am sticking with 630m 10mW ERP WSPR rather than trying 8m QRP FT8. In the last hour, 3 English stations have spotted me.

10m 500mW WSPR TX (Friday)


My 500mW 10m WSPR TX beacon is back on 500mW with the PA turned on. It is interesting that the reports today suggest 500uW would not be spotted i.e. with the PA turned off. At the moment, I have decided to stick with 630m WSPR and not go on 8m FT8.

UPDATE 1414z:  34 stations have spotted me today on 10m WSPR.

Autumn has arrived - NOT amateur radio

In the last few days autumn has suddenly arrived. A few weeks ago the trees were largely green. Now most are bare. 

This was our local churchyard earlier.

630m QRP WSPR overnight

 


13 stations spotted me overnight including OH1LSQ (1733km) 3 times.

Sunspots - Friday November 17th 2023

 Solar flux is 118 and the SSN 28.  A=8 and K=0.

630m QRP WSPR (Thursday)

My 10mW ERP WSPR from the earth-electrode "antenna" in the ground was turned on at 1642z. So far, after 1 transmission, 3 UK stations have spotted me. No great DX, but it works!

UPDATE 2015z: 7 UK stations have spotted me.

Rally news

The following rallies are due this weekend. If you are going a long way, I always advise contacting the organisers first. 

Saturday November 18th - Rochdale and District ARS Winter Rally, Norden, Rochdale, OL12 7QR.  Contact dave@cardens.me.uk .

Sunday November 19th  - Coulsdon Amateur Transmitting Society (CATS) Bazaar,  Old Coulsdon, CR5 1ES. Contact bazaar@catsradio.org.uk .

8m QRP FT8 (Thursday)

 My 2.5W 8m FT8 was turned on at 1413z.  No spots at 1617z.

Fog of war - NOT amateur radio

When there are wars on it is very hard to discern the truth as all sides tend to distort the truth. This was true in the Vietnam war and was certainly true in WW2. 

At the moment, in the Middle East, it is hard to untangle the facts. Clearly Israel wants to eliminate the threat from Hamas. At the same time, many innocent people are being killed or maimed and their homes destroyed. The best way I have found is to listen to the news from both angles and try to make up your mind on the truth. With the "fog of war", this is hard.  

The only thing for certain is that all involved bend the truth!!

10m uW WSPR (Thursday)

My 10m WSPR beacon is still turned on but with the PA turned off. No spots. My beacon is pre-programmed to say 0.5W, even though the power is actually about 500uW.

UPDATE 1630z:  Unless things dramatically change, I think spots of my 500uW on 10m WSPR TX are very unlikely today. Tomorrow, I shall probably revert to 500mW, i.e. QRO for me! I guess the issue for many is now a high local noise floor.

630m overnight


With 15 stations spotting me overnight (on 630m WSPR with 10mW ERP) this is my best this season. Once again the best were 3 spots  by OH1LSQ (1733km).

Sunspots - Thursday November 16th 2023

Solar flux is 119 and the SSN 41. A=12 and K=2.

630m QRP WSPR (Wednesday)

 My 10mW ERP from the earth-electrode "antenna" in the ground was turned on shortly after 1730z.

UPDATE 1736z:   2 spots of me so far.

Fungi - NOT amateur radio

 

This fungi was on a log at Anglesey Abbey, near Cambridge, earlier.  At one time there was a hornet's nest here.

Medieval stained glass - NOT amateur radio

 

This stained glass is in King's College Chapel in Cambridge and dates from the 1500s.

As locals, we can get in to the chapel free.

The chapel is darker than normal as there is scaffolding and tarpaulins outside.

8m QRP FT8

My 8m QRP (2.5W) was turned on about 0920z.  No spots yet.

UPDATE 1442z: An Irish station called me, but we were unable to complete the contact.

UPDATE  1725z: No spots of me today on PSKreporter.  Shortly QSYing to 630m WSPR.

10m uW WSPR TX

A reminder that today I am trying my 10m WSPR beacon with the PA off. According to my TinySA spectrum analyser the output is about 0.5mW or 500uW. This is pre-programmed to show the power as 0.5W even though the power is actually 30dB lower. As yet, no spots.

UPDATE 1720z: No spots all day. I think conditions have to be well up for this to succeed.

630m WSPR overnight


12 stations spotted me overnight whilst I was using 10mW ERP from the earth-electrode "antenna"  in the ground.

Sunspots - Wednesday November 15th 2023

Solar flux is 124 and the SSN 86.  A=6 and K=1.

Bus shelter - NOT amateur radio

We go by this bus shelter every week. Only recently have we noticed how mossy the roof has become. 

We have had a very wet autumn.

10m uW DXing

As an experiment tomorrow, I may leave the PA turned off on my 10m WSPR TX beacon. It is pre-programmed to say 0.5W, but I would guess the actual power out is microwatts. I must check the difference on a spectrum analyser.

My guess is some single digit reports of me might still be copied if my PA was off. Today, there were several such reports. I guess it also depends on the RX station having a low noise floor.

UPDATE 2150z:  Using my TinySA spectrum analyser, it looks like the TX is 30dB weaker with the PA turned off, so the output is about 500uW. I wonder how many will be able to spot this on Wednesday?

10m 500mW WSPR TX

My 10m WSPR TX beacon was switched on about 30 minutes ago. Several spots already.

UPDATE 1656z:  54 spots of me today.

8m QRP FT8 (Tuesday)

Once again, I am on 8m WSPR with my 2.5W and dipole. Of course, my PL259 plug failed and a high VSWR resulted. After resoldering (hard these days), I am back on the air. No spots yet.

UPDATE 1015z:   Just local spots of me by G4WSZ (12km).

UPDATE 1647z:  3 stations have spotted me: 2 UK and 1 Caribbean.

Windy - NOT amateur radio

Yesterday we had strong winds. Many of the trees in our garden lost plenty of leaves. The next milestone will be looking for the first buds to appear in the spring.

Waxwings - NOT amateur radio

In the winter time waxwings (pinkish almost starling sized birds with crests) fly to the UK from Scandinavia because food is more plentiful. They are often spotted eating berries in supermarket car-parks. In all my years, I have never seen one!  It is not for the lack of looking either.

See https://www.rspb.org.uk/birds-and-wildlife/waxwing .

630m QRP WSPR overnight


13 stations spotted me including 4 spots from OH1LSQ (1733km) in Finland and two from Norway. Not bad with 10mW ERP from the earth-electrode "antenna" in the ground.

Sunspots - Tuesday November 14th 2023

 Solar flux is 134 and the SSN 85. A=16 and K=1.

This morning, we went shopping. This was our shopping cart.

630m QRP WSPR (Monday)

My 10mW ERP WSPR from the earth-electrode "antenna" in the ground was turned on about 1705z.

UPDATE 1720z:   2E0ILY/KIWI (209km) has spotted me.

UPDATE 1940z: 7 UK stations have spotted me this evening.

10m 500mW WSPR TX (Monday)

 My 10m QRP WSPR TX beacon was turned on at about 1504z. So far, I have been spotted by 28 stations.

8m QRP FT8 (Monday)

 My 2.5w system was turned on at about 1503z. So far just local spots.

UK Home Secretary - NOT amateur radio

The UK Home Secretary was Suella Braverman. She has been sacked according to the BBC website. The job of Home Secretary is a most important one needing someone in the position who gains the respect of all the people with whom this person interacts.
