We live next door to the only remaining windmill in our village. At one time there were four.
More accurately, some of these were windpumps, not windmills, as they were used to pump water and not grind corn. The photo shows two of these that have now gone.

Sunspot minimum
My favourite site for solar data has changed the wording giving the months when sunspot minimum occurred. Previously it was hedging bets using works like "probable". 2 dates are given as the date depends on how the averaging is done.
The climb begins....

Facebook memory - PW
7 years ago there was a review of mine in Practical Wireless. It was quite a surprise to see my bald head and garden on the cover! Since then PW has changed owners.

Busier Oscar 100
Just a few moments ago I took a peak at the narrowband section of Oscar 100, the geosynchronous satellite. Last time I looked it was exceptionally quiet. Today, at a weekend, there were 7 QSOs going on which is typical of the last year.

Short-term Aims? - NOT amateur radio
Perhaps this is a natural feature of old age? I seem to have aims that are more short-term these days. Perhaps I am more aware of the finality of life than I was and every day is a gift to be enjoyed. Life is never perfect or easy, but there is so much to be thankful for.

International Short Wave League (ISWL)
For two periods I was an ISWL member. When I first joined in the 1960s it was a thriving club. I rejoined many years later but then must have had far fewer members. These days it must be struggling unless it has had an influx of new members, that I doubt. In its day it served a real purpose.

Thunderstorms?
It has been hot all day. According to the weather forecast we could have thunderstorms later. If so, everything will be disconnected in the shack.
UPDATE 1845z: QRT on all bands as it looks stormy.
UPDATE 2025z: Just a very slight rain shower. I think the storms passed us by.

Lunch in the garden - NOT amateur radio
Today the temperature is 32 deg C right now. Lunchtime we ate in the garden. This is me tucking in to pasta. We came in later as it was too hot.
QSY to 2m FT8
Stations spotting my 10W FT8 on 2m today |
So far, my 10W to the big wheel omni antenna has been spotted by 16 stations in 4 countries (it is now only 1406z) with best DX a spot by GI6ATZ (479km). Not bad in just 8 minutes with low power!
MLS IC-705 unboxing video
MLS has got hold of an IC-705 ICOM transceiver. On the "something for the weekend" video they do an unboxing. See the MLS website.
Distant Kings - NOT amateur radio
On our walk earlier this morning we could see Kings College in the far distance. The university library is also visible. Sorry the photo is so poor!
10m WSPR TX (500mW to the indoor loop)
At 0833z, the W5OLF 10m WSPR beacon was turned on. Already spotted by a Swiss station by Es.
UPDATE 1409z: Spotted by 3 unique stations so far.

Early walk - NOT amateur radio
As today is supposed to get very hot, we did a very early morning walk. We set off at 0545z! The photo shows me on the walk around the nearby village of Reach. This is a delightful walk with a mix of views. At one point we could just make out the roof of Kings College Chapel, about 10 miles way in Cambridge.
Gone? - NOT amateur radio
As the weather was hot in the east of the UK yesterday, we spent some time in the garden in the late afternoon. What was different?
In May, June and July the screaming sound of swifts feeding on the wing was very common. Yesterday was different. In nearly an hour I saw just 1 swift.
The impression is that younger swifts hav seen overheade already started their migration back to central Africa. Normally most adult birds leave by mid-August spending just a few months here to return next April/May.
They are ephemeral birds: when they are with us they are very common - usually the screaming is heard first - then they are gone again and the skies are quiet. On better evenings 20 plus birds can be seen overhead.
To me, they are symbols of a UK summer and I miss them when they go and eagerly look forward to their return next spring.
UPDATE 0840z: 6 swifts seen overhead this morning.

2m FT8
Just after 1900z, I QSYed fron 6m FT8 to 2m FT8. I am using 10W to the big-wheel omni antenna. So far (it is now 1908z) My signal has been copied by 19 stations in 3 countries. Best DX spot of me was by GD3YEO (384km).
G4CLA (106km) is getting me at an incredible +14dB S/N. I suspect he must have a very big antenna and a superb take-off. In most 2m and 70cm activity contests he works me even though I only run 10W and a 2m big-wheel omni antenna.
UPDATE 2052z: QRT.

Wineberries - NOT amateur radio
On our visit to nearby Anglesey Abbey we noticed these berries. They looked like raspberries (perhaps a bit smaller) but were in clusters. Investigations suggest these are wineberries which came from Japan. I am told they are edible (but do check as I am no expert!). I had not seen them before.

10m WSPR beacon (500mW to the indoor loop)
At about 0845z I turned on my little W5OLF 10m WSPR TX beacon. Yesterday was amazing. Nothing yet so far today.

6m FT8
At about 0845z, the 6m FT8 gear was turned on (10W to the V2000 vertical omni). Already there is lots of Es around. Already spotted by 6 stations in southern Europe.
UPDATE 1145z: So far this morning I have been spotted by 15 stations and I have spotted 30 stations. Just 1 QSO so far.
UPDATE 1417z: The Es seems to have stopped for now. 16 stations have spotted me today on 6m FT8 and I have spotted 36 stations.

This photo (shown before) shows where I come from in South Devon. We owned some land here in the 1400s.
Oscar 100 - SO quiet!
Yesterday lunchtime I took a listen on the geosynchronous Oscar 100 satellite. When I listened to the narrowband transponder on the web SDR at Goonhilly I was amazed how quiet it was. The only QSO was one between a G and an F.
Especially with so many at home, I was expecting it to be quite busy by now. I think people lose interest after they make their first QSOs.

Yesterday's walk - NOT amateur radio
Sugar beet (I think) |
Yesterday was no exception so we walked up to the Devil's Dyke, an ancient man made structure in Cambridgeshire built about 1400 years ago. It is about 7 miles long and is a defensive earthwork. How did they get the manpower?
There is another earthwork with the same name near the south coast of the UK.
On our way we saw fields of sugar beet (I think) and sweetcorn. Years ago you would not have seen sweetcorn. Nowadays you see fields of sunflowers and sweetcorn. These are crops that grow well here due to the climate warming.
Because of my giddiness, each walk seems a lot longer. All the time I feel as if I am about to fall so I have to watch each step. This is particularly hard on pavements (sidewalks) as it seems as if I am about to fall into the path of cars. When cars are coming up from behind it is particularly unnerving.

70cm activity contest results
The results of the RSGB organised activity contest have published.
It shows my position in the low power section has improved.
I am only using 10W and my 2m big-wheel omni antenna. Because of my voice I stay on for less than an hour.

Zoom meetings - NOT amateur radio
Since the lockdown many of us have had to rely on Zoom to see friends and family. I have been impressed. The photo shows a Zoom meeting earlier.
What a difference a day makes!
As yesterday, my 500mW 10m WSPR beacon was turned on with the tiny indoor loop antenna. Yesterday no spots all day yet already several from Norway even though it is only 0742z.
UPDATE 1110z: 10 unique stations have spotted me so far.
UPDATE 1857z: Today is the best day this season on 10m WSPR TX with 34 unique stations spotting me so far. Nothing yesterday at all, then today!!

Growing up fast - NOT amateur radio
The photo shows our "London" grandchildren next to a yew tree almost 1000 years old. Quite humbling to think it has stood here that long. It puts their age in context.
Pye Telecom PF8 transceiver
This radio, that I helped to design, has gathered a cult status over the years. It was the radio used on the UK TV series called "The Professionals".
Some have been converted to use on 70cm. Before anyone asks, no, I cannot help you find one! They are rare these days. I do not possess one and neither do my old colleagues. My best advice is keep your eyes skimmed in case any appear on eBay or at rallies. Looking back, we did not sell that many. We made more pagers in one night, than the total number of PF8 units sold.
That was the trouble with PMR radios. Once we faced significant price competition, we just could not compete. These days you can buy UHF PMR transceivers for a fraction of the price 40 years ago.
On my website is a .pdf version of the manual.
In its day, way before cellular radios, it was quite ground breaking.
