Climate change - NOT amateur radio

Whatever your views on recent protests by Extinction Rebellion around the world, there is little doubt, unless you are Canute or Trump, that the world is getting warmer. Most experts agree and you only have to look with your own eyes.

People may argue whether this is mankind's influence or a natural variation. The evidence points to the former. In time, we will all move away from fossil fuels (like we did with flat screen TVs and digital cameras), but it is arguably not soon enough. In the meantime, we may be doing irreparable damage.

Israel Amateur Radio Club

Ok, I could use Google Translate to convert these pages into English, but I did not bother. Apparently there will be a special station to celebrate the Eurovision Song Contest from Israel. It would not surprise me if the UK was bottom this year! I am not quite sure why we still take part. Like Trump, the UK is a laughing stock and the butt of jokes at this event. Mind you, can you blame people?

Sponsorship? - NOT amateur radio

Our local museum and windmill have reopened after the winter. It looks like they are being sponsored by our local co-op shops.

BREXIT: all quiet - NOT amateur radio

After hearing about BREXIT non-stop, it is out of the headlines now and hardly gets a mention. There were talks between the UK government and the opposition aimed at finding a compromise, although, as far as I know, nothing has been reported.

The truth is the nation and MPs are deeply divided. Some are very keen we should leave, even with no deal, whilst others think we should stay. Some want a vote on whatever deal is agreed. The UK Prime Minister is still trying to get her deal approved by the UK Parliament.

A mess? I couldn't possibly comment.

6m FT8

After a night off (PC and rigs off) this morning I have returned to 6m FT8, mostly RX. So far 4 Gs spotted.

Grandchildren - NOT amateur radio

As usual over Easter, we have been busy with grandchildren.

Our local museum has just (today) reopened, so we went across there earlier.

The photo shows one of the grandchildren in the museum next to an Austin 7.

Good news on the BBC - NOT amateur radio

We seem to be fed lots of bad news (I guess this makes papers sell) but tend to not hear about good news often. So, we end up thinking the world is all gloom and doom. In actual fact the good news far outweighs the bad. So let me bring you some good news for a change!

See https://www.bbc.co.uk/news/health-47974844

6m FT8 RX

You can tell there is a contest on! In the last day a total (so far) of 66 stations spotted (mostly Gs) in 7 countries with best DX spotted F4IAA (802km).

UPDATE 1252z:  Now 85 stations spotted in 10 countries spotted on 6m FT8 RX in the last day. Best DX is IZ5YFU (1222km).

UPDATE 1610z: 76 stations spotted in the last day on 6m FT8 RX in 10 countries. Mostly tropo I think. The photo shows those received, although missing is the station in N.Ireland. One station spotted my CQ recently (2.5W). This was M0TXS (56km).

6m MGM contest: stations 

received on vertical co-linear antenna.

Simple AM radio

Southgate News carries a report of someone's first steps into RF by building a simple TRF circuit. It uses a TA7642 TRF IC, which is like a ZN414 that some may remember. These form the basis of very simple TRF receivers. I recall making a similar circuit years ago for Medium Wave. As I recall, mine was fix tuned to Radio Cambridgeshire. I guess these ICs could be used for a simple RX in a 160m AM rig.

Sunspots - Sunday April 21st 2019

Solar flux is 71 and the SSN 11. A=4 and K=1.

Like busses? - NOT amateur radio

The same thing happened last year. One day I saw my first swallow (bird) then the next day I saw more!  Today, I saw 2 more swallows. Next week, they should be common.

Easter Egg Hunt - NOT amateur radio

Our grandchildren are still young enough to enjoy hunting for chocolate Easter eggs hidden in the garden as the photo shows.

472kHz WSPR overnight

Considering it is quite late in the season, not a bad night. 6 people spotted my 10mW ERP  with my best spot being by PA0O (440km). On RX my best spot was of IW4DXW (1190km).

472kHz WSPR here overnight

6m FT8

Earlier, I called CQ on 6m FT8 and was spotted by 3 G stations. Later (it is now 1040z) 11 stations were spotted with best DX ON4CGB (242km).

UPDATE 2040z: Now 52 stations in 5 countries spotted on 6m FT8 today. There is a contest, so activity is greater than normal. Best DX is MM0CEZ (487km). Most stations are in England.

Sunspots - Saturday April 20th 2019

Solar flux is 72 and the sunspot number 23. A=4 and K=1.

472kHz WSPR (10mW ERP) overnight

Sunspots - Friday April 19th 2019

Solar flux is 74 and the SSN a respectable (for where we are in the cycle) 24. A=3 and K=1.

Probing? - NOT amateur radio

A few moments ago I had a shock: visits to this blog are way above normal. I can only assume this a mistake or hackers are doing their usual probing.

One last time?

This evening and overnight I am again on 472kHz WSPR (10mW ERP) using the earth-electrode "antenna" in the ground. So far, just a couple of stations spotting me with best DX a spot by M0XDK (80km). Only M0FMT (51km) here so far this evening on 472kHz WSPR RX. I am 20% TX and 80% RX.

Depending on results, this may be my last "outing" on 472kHz until the autumn.

UPDATE 2130z: Well, so far 4 stations spotted here with best DX (who else?) but LA8AV (1035km). The best spot of my QRPP signal is by G0LUJ (278km) in IO83 square.

OFCOM and 5G licences

OFCOM is consulting on possible changes to operator licences at 3.4GHz to bring them into line with the EU.

At last! - NOT amateur radio

Just seen the first swallow (migrant bird) flying over at lunchtime. There may have been some a few days ago, but this was my first positive sighting here. The others were flying away and there was some doubt. The earliest I have seen them here is April 7th.

Coffee in the garden - NOT amateur radio

As it was warm and sunny this morning we had coffee in the garden for the first time this year. My wife also hung out some washing for the first time this year.

10m FT8

A few moments ago I QSYed from 2m to 10m FT8, calling CQ initially (2.5W) and then RX only. So far, no spots. Mind you, it is only 0850z.

UPDATE 0950z: A couple of spots so far with best DX on 10m FT8 RX being F5OHM (631km) in central France.

UPDATE 1148z: Now 5 stations in 3 countries spotted on 10m FT8 RX this morning with best DX CS7AKZ (1651km).

UPDATE 1322z: 9A7JCY was an amazing +17dB S/N signal - this must be Es!

UPDATE 1516z:  10 stations spotted in 6 countries so far on 10m FT8 RX.

UPDATE 1806z:  Now 11 stations in 6 countries today on 10m FT8 RX.

2m FT8 RX

Although it is only 0835z I have already spotted 16 stations in 7 countries in the last 6 hours. It really is amazing.

Shortly, I shall probably QSY to 10m FT8.

Sunspots - Thursday April 18th 2019

Solar flux is 74 and the SSN 11.  A=3 and K=1.

2m FT8

At about 0745z I started on 2m. After an unsuccessful call to a Dutch station and a brief period calling CQ (2.5W to the horizontal omni antenna) with 9 reports so far with my best being a spot by G4RRA (333km) in Devon, I have been RX only.

So far this evening, 20 stations spotted in 4 countries with best DX on 2m FT8 RX DL6YBF (471km).

Interesting that in just 45 minutes on 2m FT8 RX I have spotted more stations than all day on 10m FT8.

UPDATE 1955z: 21 stations spotted so far on 2m FT8 RX.

UPDATE 2125z: 28 stations spotted so far on 2m FT8 RX this evening in just over 2 hours (see photo).

Anglesey Abbey - NOT amateur radio

We went for a walk here today, mainly to take some photos. Being the school holidays, it was very busy. If there were swallows about I thought I would see some at Anglesey Abbey, but we saw none.

Well trained? - NOT amateur radio

Yesterday I think I showed my son, who was staying with us for a few days, eating the breakfast he had cooked.  The photo shows him washing up afterwards.

It's usually my job, but he insisted I sat down. Usually at breakfast and just after I feel very giddy.

10m FT8 again

Yet again, I am on 10m FT8. At the moment, I am on RX only. So far this morning a couple of spots with best DX being DO9REF (526km). It is still very early.

UPDATE 1202z: Still no further 10m FT8 RX spots today.

UPDATE 1418z: Now 6 stations spotted on 10m FT8 RX today with best DX DJ1AA (660km).

UPDATE 1731z: Now 7 stations in 4 countries spotted on 10m FT8 RX  today. The distances make me think these may be aircraft reflections, although some might be Es.

Still waiting - NOT amateur radio

It is now April 17th and I have still not seen a swallow (migrant bird). There may have been a couple in the last few days flying over, but these were not definite identifications. Often, a few days after seeing the first I see plenty.

Sunspots - Wednesday April 17th 2019

Solar flux is 74 and the sunspot number 11. A=6and K=1.

Young me - NOT amateur radio

Today, I got sent a picture of me taken at school about 1965. In those days I had hair!

Oh to be that age again. I seem to have changed a lot since then. I think it was originally part of a school photo.

I seem to recall having the lapel badge as I was a librarian in the 5th year.

Notre Dame Paris - NOT amateur radio

The images of this world famous cathedral last night looked horrific and I was dreading seeing the photos this morning. Precious medieval ceilings and the spire have gone, but I was surprised just how much managed to survive. It will be rebuilt, although I may not be around to see it finished. Thick 850 year old walls stand some treatment!

See https://www.bbc.co.uk/news/world-europe-47945465

Breakfast - NOT amateur radio

For the last few days we have had one of our sons and his family staying here. For that period he got breakfast. Normally, I do breakfasts. It was a real treat.

The photo shows him eating his breakfast today. They have now gone home.

10m FT8 again

Yet again I am on 10m FT8. An earlier CQ call (2.5W) got no spots, but I have spotted 6 stations so far with best DX IU0MBJ (1471km). I suspect this latter one is Es.

UPDATE 1226z: So far today 8 stations in 4 countries spotted on 10m FT8 RX.

UPDATE 1820z: Now 10 stations spotted on 10m FT8 RX.

Sunspots - Tuesday April 16th 2019

Solar flux is 74 and the sunspot number 11. A=8 and K=3.
