10m FT8

At the moment, I am on 10m FT8 RX. Es is already in evidence, with spots of 3 southern European stations already and it is only now 0920z.

UPDATE 2130z:  A very good day with hundreds of EUs plus several (22) South Americans.

Sunspots - Friday May 3rd 2019

Solar flux today is 69 and the SSN 0. A=13 and K=2.

Carbon capture? - NOT amateur radio

There is no doubt that our burning of fossil fuels will change in the next 30 years. I expect the use of fossil fuels in vehicles will go down as electric cars get better and cheaper. However, we are still likely to burn fossil fuels, so carbon capture technology is important to reduce nett carbon emissions. There may be some progress.

OFCOM update

Apparently OFCOM has updated its Connected Nations  report.

Latest solar predictions

As you can see, this site is still predicting the minimum has been passed. If you access the blog via https you may not be able to see the image. In which case try here. 

Once we are definitely over the minimum the climb up the slope is quite rapid.

Our windmill - NOT amateur radio

Many times I have said we overlook a windmill. This was a photo taken yesterday "up the close" with buttercups in the foreground.

End of season on 472kHz?

Yet again, I was on 472kHz WSPR last evening and overnight. In all, 3 stations spotted me. I definitely get the feeling that many are leaving the band until the autumn. Last night fewer stations were copied than for many months. DX wise, I was still copying I and EA.

The table shows the 472kHz WSPR activity here last evening and overnight.

10m FT8

Although I have been on 10m FT8 since before breakfast, calling CQ initially (2.5W), no spots at all yet.

UPDATE 0900z: Just PA3BGQ (272km) spotted so far. This could be tropo or aircraft.

UPDATE 1037z: Now 4 stations spotted on 10m FT8 RX with best DX DJ1AA (660km).

UPDATE 1230z: Now 7 stations spotted on 10m FT8 RX with best DX LZ2II (2093km).

UPDATE 1740z: Now 72 EU stations spotted today on 10m FT8 RX. Presumably Es. No "real DX" here as yet on 10m today. I was half hoping we'd see some Es linking with F2 further south, meaning we might get some South American DX on 10m FT8 RX.

Sunspots - Thursday May 2nd 2019

Still the pits!  Solar flux is 67 and the sunspot number zero. A=10 and K=4.

472kHz WSPR

At about 1930z I decided to go on 472kHz WSPR (10mW ERP from the earth-electrode "antenna" in the ground). I am on TX for 20% and on RX the other 80%. At the moment best RX DX is EA4 and DL. On TX just M0TAZ (99km) spotting me.

Es blog

A friend Richard G3TFX has just sent me this link. Jim Bacon G3YLA was a well known BBC weather forecaster. He has a keen interest in sporadic E (Es) propagation. He is a well known radio amateur. 

You need to chose the date you want.

Electric cars, not yet? - NOT amateur radio

As a low power radio enthusiast (they call us QRPers), I want to buy an electric car, but still feel it is a technology that is not quite there. I feel sure there will be a tipping point when prices fall and ranges are much better. This point is still some years away, unless there is a really significant breakthrough in battery technology. At the moment electric cars are expensive and ranges are not good enough. Give it 5-10 years and things could be much different.

See https://en.wikipedia.org/wiki/List_of_electric_cars_currently_available

Burwell museum and windmill - NOT amateur radio

Please be aware that Waitrose (Newmarket) is making our local Burwell Museum one of its community projects for May. If you shop at Waitrose (Newmarket) you may want to support your local museum by putting your green tokens in the museum "pot".

Easter profits - NOT amateur radio

Even though Easter was very late this year, it has now gone. One of our leading UK supermarkets, John Lewis, was selling Easter goods soon after Christmas. This is pure commercialism and sick.

In my view, Christmas goods should not be displayed or sold before December and Easter goods no sooner than 1 month before Easter. Baa humbug :-( 

10m FT8

After a brief (2.5W) CQ call at 0825z (I was not spotted), I am now RX only on 10m FT8. As yet, no spots. It is very early, so unless there was strong Es, I might only expect near Europeans and Gs by tropo or aircraft reflection.

UPDATE 1250z: Just three G spots so far today on 10m FT8 RX. Poor.

UPDATE 1530z: Today really has been the pits! Just 4 G spots all day on 10m FT8 RX. I shall stay on until dark, just in case there is a late opening.

UPDATE 1855z: Some Es from Southern Europe around teatime.

Solar predictions

As yet, my favourite site for solar details has not yet been updated for April. This usually happens early in the new month. It will be interesting to see the forecasts for solar minimum and cycle 25 maximum dates. At odds with some other forecasts, this site was predicting we had already passed the solar minimum.

See http://www.solen.info/solar/

UPDATE 1248z: It has now been updated and still shows that we have passed the solar minimum.

160m FT8 RX overnight

Last night I was on 160m FT8 RX. As well as loads of EU stations, 1 North American was spotted. Conditions seem less good than a few months ago on 160m, but I am no expert.

Beyond meat - NOT amateur radio

I am a meat eater, but I could quite happily be a vegetarian and never eat meat again. An American company called Beyond Meat is about to float and the shares are in high demand. If the world it to feed itself in years to come we may have to eat far more non meat foods.

See https://www.bbc.co.uk/news/business-48110704 .

Sunspots - Wednesday May 1st 2019

May already! It hardly seems possible.

Solar flux is 67 and the SSN zero. A=5 and K=2.

160m FT8

Overnight I am on 160m FT8. After a brief period calling CQ (2.5W, 2 UK spots plus LB7ZG (1058km as best DX)) I have been on 160m FT8 RX. As usual, I am using the earth-electrode "antenna" in the ground. This is a good match on 160m.

As normal, loads of EU stations spotted on 160m FT8 RX.

Stations spotted on 160m FT8 

RX in the first few minutes!

6m FT8

At about 1430z 6m FT8 beckoned. Initially a CQ (2.5W) and was spotted by M0TXS (56km.) A few Gs have been spotted on 6m FT8 RX.

10m WSPR

At about 1430z I QSYed to 10m WSPR TX with my 500mW stand-alone beacon. This llows me to go on 6m FT8 at the same time using a different antenna.

UPDATE 2050z: Now QRT. No 10m WSPR spots today.

10m FT8

Although I have been on 10m FT8 since before breakfast, very little doing yet. The only station spotted so far is G4HZW (212km) in NW England. Judging by the strength, this is probably normal "flat band" tropo. An earlier CQ (2.5W) was spotted by no-one.

UPDATE 0947z:  No further 10m FT8 RX spots here today.

UPDATE 1202z:  Just 2 G spots today so far on 10m FT8 RX. Abysmal!

Overnight on 472kHz WSPR

Yet again, I was on 472kHz WSPR overnight. Not a bad night with my 10mW ERP from the earth-electrode "antenna" in the ground spotted in 4 countries with the best being a spot by DL/PA0EHG (493km).

New politics? - NOT amateur radio

Something on the BBC website this morning hit me and got me thinking. Are we on the verge of a sea change in politics?

Here in the UK and probably much of the west, young people are finding meaningful work hard to get. In the UK houses are generally far too expensive for young people to buy. In several countries right wing parties are picking up the disaffected votes.

Maybe we are seeing the ending of traditional politics and a new wave of politics is about to be ushered in? The old ways on the left and right probably have had their days, so maybe now is ripe for something different?

I have no idea what this will be, but just maybe we will see the beginnings of a fairer, more sustainable economy in the UK, the rest of the EU and the USA? We live in challenging times.

See https://www.bbc.co.uk/news/business-48069016 .

Sunspots - Tuesday April 30th 2019

Solar flux is 67 (poor) and the SSN still zero. A=5 and K=2.

QSY to 472kHz WSPR (10mW ERP)

At about 1900z I QSYed from 28MHz FT8 to 472kHz WSPR using 10mW ERP (20% TX) from the earth-electrode "antenna" in the ground. So far, the usual stations spotted and spotting me.

Build project?

Although my health is less than brilliant, my XYL insists that building something would be good for me. Now you know how it is! These commands have to be obeyed!

Somewhere in a drawer, I have an unbuilt 20m Rockmite kit, although I do not have a very good 20m antenna. A few years ago (after my 2013 stroke) I managed to build a 40m Pixie transceiver kit and it worked.

The Rockmite really does not enthuse me. If you have any ideas for simple projects I could build, let me know. At one time almost anything was possible. These days even simple things are hard.

Plymouth Argyle - NOT amateur radio

OK, I am a fireside football fan and it is very many years since I attended a real soccer match. However, I do keep and eye on some teams of interest and one of these is Plymouth Argyle, which was my local team many years ago.

At the moment they are likely to be relegated to League 2 in the UK. This is the lowest tier. They have just sacked their manager. If they survive it will be by the skin of their teeth. At the moment this seems unlikely.

Ferns - NOT amateur radio

Ferns are fascinating. Those in the photo were seen at Anglesey Abbey earlier today. They are about to unwind.

10m FT8 again

Yet again, I am on 10m FT8, mainly RX. Yesterday there was plenty of Es propagation on the band and it remains to be seen how things work out today. If there is any "real DX" i.e. South Africa or South America, I don't expect to spot these until after lunch.

An initial CQ call today just after 0800z was spotted by no-one! Let's hope things here improve.

UPDATE 0915z: No spots yet on 10m FT8 RX today.

UPDATE 1415z: So far today, 54 EU stations spotted, presumably Es. As yet, no "real DX" spotted here on 10m FT8 RX.

Stations spotted here today so far on 10m FT8 RX

UPDATE 1850z: 59 stations spotted today on 10m FT8 RX. Most are via Es. It seems unlikely there will be any "real DX" via F2. I shall shortly QSY to 472kHz WSPR.

472kHz WSPR overnight

Not a bad night (for the time of year) with 5 stations spotting my 10mW ERP from the earth-electrode "antenna" in the ground with the best being DL/PA0EHG (493km). I spotted 4 stations here. I think the Norwegian stations were not active.

433MHz superhet modules - dirt cheap

Although my health precludes doing much RF design and construction these days, I see you can buy TX and RX module pairs for 433MHz for about £3 with free postage on eBay.  I guess a half capable designer could build a useful pair of transceivers for local 70cms AM comms for under £10. There may already be designs published, although I've not seen these. If you have, please share a link.

Try looking on eBay for "433MHz RF modules". To a capable designer, these could be quite useful. No doubt with a bit of digging you can get these for even less!

UPDATE 1345z: Check out the YouTube videos by VK3YE who has done some interesting tests with similar modules. It appears you can get FM or AM with these and some useful ranges.

Sunspots - Monday April 29th 2019

Solar flux is 67 and the sunspot number is again zero. A=6 and K=1. Pretty poor!

472kHz WSPR

A few moments ago I QSYed to 472kHz WSPR (10mW ERP from the earth-electrode "antenna" in the ground). As usual, I am 20% TX with the remainder of the time on RX.

So far, 1 station has spotted me and 1 station spotted here.

Maggie - NOT amateur radio

Maggie is now a very old horse. She has been a favourite with grandchildren who like to find her grass to eat.

She is in a new paddock. I'm sure she loves attention from children. She is part of our lives.

What polarisation for VHF and UHF DX?

Ever since I started in the hobby I was told, "vertical FM for locals and horizontal for SSB/CW". Now, like many things, I have found that so called "experts" are not! My own, albeit limited, experience on 2m and 70cm is, at best, inconclusive. On 70cm FM I have made some great DX QSOs and also on 2m FM with vertical polarisation.  At the same time I have worked some great DX on 2m SSB with horizontal polarisation.

According to Southgate News, someone has done some recent research. It would not surprise me if there was actually little difference! Funny how old wives tales become facts. Don't always believe what so called "experts" have to say.

Many said my own earth-electrode "antennas" in the ground would not work, but these have now been used from ELF-MF successfully and I am pretty sure at least one VLF grabber is now using such a structure. No, experts are often wrong. Always challenge! That is part of the fun of our hobby.

See http://southgatearc.org/news/2019/april/horizontal-versus-vertical-antenna-polarisation-the-debate.htm#.XMVi2PZFy00

This was a talk on the polarisation of 6m signals given to the Reading club. The link worked for me, even though I am not a club member.

472kHz WSPR

Well, I have come to the conclusion that the band is still quite decent, but stations are abandoning it at the moment. Overnight 6 stations spotted my 10mW ERP from the earth-electrode "antenna" in the ground and I spotted 7 others with my best DX a spot of EA4GHB (1300km).
