Village walk - NOT amateur radio
We have just got back from a walk around the village. Plenty of swifts around. More cars than there were.
10m WSPR and 6m FT8
It dawned on me that I can be on 10m WSPR TX and 6m FT8 at the same time using my 10m WSPR TX beacon and the indoor loop whilst using the PC, FT991A and the V2000 vertical antenna on 6m.
UPDATE 0815z: 18 spots of me on 6m (10W to V2000), but nothing on 10m WSPR TX (0.5W to the indoor loop).
UPDATE 1100z: Plenty of spots of my 10W on 6m FT8 but still nothing on 10m WSPR yet. Does this mean my antenna is inefficient or there are now far more people on 10m FT8? I suspect the latter.
UPDATE 1153z: 50 stations have spotted my 10W 6m FT8 so far. Nothing on 10m WSPR.
UPDATE 1320z: Still no 10m WSPR spots, but 58 spots of my 10W 6m FT8. I actually am surprised not to get any 10m WSPR spots. I know many have moved to FT8, but I would have expected something.
UPDATE 0754z: The whole day without any spots at all on 10m WSPR. Tomorrow I shall try 10m FT8 with 2.5W to the indoor loop for comparison.

2m activity contest 1900z (8pm UK time) tonight
Stations worked this
evening on 2m SSB
|
I stay on for less than 1 hour because of my poor voice. This is a friendly contest. Although there are few (or no) portable stations, there could well be more operation from home. I run 10W to the big-wheel omni antenna.
UPDATE 2037z: 9 QSOs this evening.
6m FT8
A few moments ago the 6m FT8 gear was turned on. There is Es about as 1 G is calling an Italian station. So far, 3 stations have been spotted and I have been spotted by 8 stations (at 0915z) including 2 in Northern Spain. As usual, running 10W to the V2000 vertical omni antenna.
UPDATE 1037z: Several spots of my signal across Europe and one QSO with an Italian so far today.
UPDATE 1301z: 51 stations have spotted me today with QSOs from Finland to Italy with 10W FT8 on 6m.
UPDATE 1602z: Up to now 76 stations have spotted my 10W FT8 on 6m. It seems I call CQ and someone answers!
UPDATE 1847z: Looks like a similar total to yesterday in terms of stations spotting my 10W.
UPDATE 1858z: QRT.

Early walk - NOT amateur radio
East Cambs net
Last night, Monday, at 1900z (8pm), we had the 2m FM East Cambridgeshire net on 144.575MHz.
Not sure if this is a result of the lockdown, but we are regularly getting more people now. We are a friendly bunch and we are usually finished after about 30 minutes. If you are in the area feel free to join us.
We get joined by people that I would not expect i.e. they are some way away.

Dodgy marketing - NOT amateur radio
This sickens me.
About 10 days ago I spotted an advert on Facebook that I reported for abuse. It is still there. Their clever tricks are (a) to pray on Covid-19 fears, and (b) by saying there are only so many left in stock encouraging people to place an order immediately. Magically, the stock level suddenly goes up again. Every time I look this happens.
Do NOT do business with people like this!!
I could name them, but I do not want to give them free publicity. They are selling a clip-on device to measure oxygen levels in the blood. Look up oxymetre . The company name starts with "oxy".

Swifts - NOT amateur radio
Amazingly, although I have not yet seen a swallow, a solitary swift flew over just now. This is the first time I have ever seen a swift before a swallow.
UPDATE 2015z: Quite a few in the sky tonight. When they return, my heart rejoices.

Swallows (migrant birds) - NOT amateur radio
Normally I see my first swallows by mid April. It is now May 4th and I have still seen none!! Last year there were not as many, but this year is appalling. Usually swifts start to arrive about now. There are some swallows in Devon, but I get the feeling fewer.
Woodland walk - NOT amateur radio
Yesterday, we did a nice walk partly through woodland at Landwade, near Newmarket. It was very quiet - in fact we met no-one at all!

40MHz (8m)
It is some time since I caught up on who has access to the 8m band (40MHz). Southgate News reports on an FT8 QSO between EI and LY. I did not realise LY had access to the band!
Apparently LY does not have general access and this station had special permission to use certain spot frequencies. Others might like to try for similar access permits.

Stations spotting me on 6m FT8 today to 1230z |
UPDATE 1337z: Now 81 stations spotting me today on 6m FT8.
UPDATE 1758z: Now 98 stations have spotted my 6m FT8 today.
UPDATE 1843z: I have to go QRT on 6m shortly, but today has been the most successful this Es season.
2m FT8
After finishing on 6m FT8 yesterday, I went on to 2m FT8 with my 10W and the big-wheel omni. As usual, stations spotted in England, Netherlands, Channel Islands and Germany. My own signal was spotted by 10 stations in England and Wales. I was not on that long.
ARRL website - high sensitivity crystal set
The ARRL website has much to commend it, including this article that was in QST some years ago on a high sensitivity crystal set using a zero bias MOSFET.
There is more about crystal sets on my main website. They are capable of some quite remarkable results.

75 years ago - NOT amateur radio
Already I have mentioned that my dad was an RAF Pathfinder. These were elite flyers, many of whom died. 75 years ago, at the end of the war, he was getting prisoners of war back home and dropping food on the starving people of Holland.
When he went on the Lubeck trip he requisitioned all the newspapers in the mess destined for officers and gave them out to the PoWs. Of course, some had not seen UK newspapers for years!

10m FT8 again
On 10m FT8 (2.5W to the indoor loop) and being spotted in Spain and Scotland, presumably by Es.
UPDATE 1327z: 141 10m FT8 stations spotted, 10 stations have spotted me and 1 QSO with France so far today.
UPDATE 1338z: My 10m band indoor loop is surprising me. Without a full-sized outside antenna it is hard to know what I am missing, but my impression is not much. Already this morning it is copying Es from all over Europe and a few days ago was spotting South Americans. For FT8, the sharp tuning is not a problem and might even be a bonus keeping strong signals and noise off frequency down in level. My impression is it is very little down on a full sized outside antenna. There should be some directionality, although I seem to copy, and be copied, in all directions. Perhaps if it was external this might be more obvious.
UPDATE 1458z: 184 stations spotted so far today and I have been spotted by 16 Europeans.
UPDATE 1730z: Now 237 stations spotted on 10m FT8 RX as well as 26 stations spotting my 2.5W to the indoor loop.

Solar forecast page updated
My favourite page for solar forecasts has been updated.
It still shows that we have passed the solar minimum. Recent sunspot numbers suggest this is correct. If so, we can look forward to better conditions in the years ahead.
It is definitely worth keeping an eye on the FT8 frequencies.
Even around the solar minimum paths from the UK to South America open regularly. People have worked South Korea on 10m around the solar mimimum from the UK.
See https://www.solen.info/solar/

FT8
This digital mode is like a certain UK yeast spread: you either love it or hate it! Sadly, I think it has resulted in less SSB activity on HF and VHF bands. For me, with my poor voice, it is ideal as it only needs 50Hz of bandwidth, works with very weak signals and concentrates activity within a few kilohertz on each band. QSOs (albeit rubber stamp ones) can be completed very quickly. It works well with lower power and simple stations. Someone estimated it is about 17dB better than SSB. That is a lot!

Dad - NOT amateur radio
Before now, I have mentioned that my dad was a Pathfinder flying Lancasters in WW2. I think he hated killing innocent people and this haunted him all his life. He died in his late 60s in 1987.
Today was his birthday and he would have been 102.
At the end of the war he dropped food over Holland and helped to bring prisoners of war home.

Dawn chorus - NOT amateur radio
In the northern hemisphere it is springtime. Because of the lockdowns in many countries, it is quieter and sounds can be more easily heard.
The RSPB has a good video on the dawn chorus for those of us unable to experience it at the moment.

Moxon antennas
It was many years ago that I built a simple 70cm Moxon antenna in well under an hour from an old coat hanger. I used this when out portable in a contest and it worked well.
Moxons have been made from HF to UHF. They are easy to make, have useful gain and bandwidth, a good front to back ratio and are quite broadband. In summary, they are useful antennas.

10m FT8
At about 0905z I turned on my 10m FT8 gear. As usual I was running 2.5W to the indoor loop. There looks like there's plenty of Es about already!
