Typical Oscar 100 RX

This picture appeared today. It shows a typical Oscar 100 (geosynchronous) satellite RX. At some point I may have a go. It seems to be working well. I guess the trick is to dual feed the dish so both the 2.4GHz uplink and the 10GHz downlink share the same dish.

ISWL

Twice I was a member of the International Short Wave League. Once in the 1960s and I rejoined many years later. I left again after several years as it no longer seemed to reflect my interests.

Back in the 1960s it was quite strong. In later years, it was much weaker and I had the feeling it was dying out. I see it is still around today. When I eventually left, having contributed many articles for the club journal "Monitor", not even an email to say, "sorry you are leaving". I guess this would have been about 2011, although I cannot remember.

If anyone knows how many members of the ISWL there are today, I'd love to know. It would not surprise me if there are less than 100 members left. When I left for the second time, I seem to recall there were about 300 members.

40m FT8 RX overnight

Overnight I remained on 40m FT8 RX, despite my very poor, low, antenna. At least this must give others hope! In all, 591 stations spotted on 40m FT8 RX in 5 continents. Best DX was PY2BL (9531km). Even in the last 30 minutes, I am still spotting North America on 40m FT8 RX.
40m FT8 RX spots in last day
UPDATE 1422z: I stayed on 40m FT8 RX today. 665 stations spotted on 40m FT8 RX since I switched to 40m yesterday. This seems to be the main DX band at this part of the solar cycle.

Sunspots - Thursday (yes it definitely is!) March 28th 2019

Solar flux is 69 and the SSN 0. A=6 and K=3.

40m FT8 RX

About an hour ago I QSYed to 40m FT8 RX. So far this evening 126 stations spotted on 40m. My antenna is very low and far from ideal for 40m.

UPDATE 2136z: South and North Americans now being spotted on 40m FT8 RX. Best DX is PY2BL (9531km).

UPDATE 2150z:  188 stations spotted this evening on 40m FT8 RX.
Stations spotted so far this 
evening on 40m FT8 RX.

20m FT8 RX

As 10m FT8 was so dire, I QSYed to 20m FT8 RX. So far, in a couple of hours 139 stations in 3 continents spotted.

UPDATE 1939z: 151 stations spotted so far.

10m FT8

Since 0745z, I have been on 10m FT8. Initially I called CQ (2.5W), but after a few minutes I have been 10m FT8 RX only. No spots of my CQ, but surprisingly a couple of stations spotted on RX with best DX F1SCR (435km).

UPDATE 1435z: Just 3 spots today (2 Gs and 1 F) so far.

UPDATE 1445z: As 10m is so poor here today on my setup, I have QSYed to 20m FT8. The antenna is even poorer on 20m, but at least there is some activity

2m FT8 RX

Until breakfast time, I stayed on 2m FT8 RX. In all, 36 stations spotted since early last evening. Some were probably aircraft reflections, but I suspect most were normal "flat band" tropo as I seem to be spotted by some DX stations whenever I call CQ, so this is very unlikely to be aircraft reflections, which would be strong and depend on when the aircraft is/are in the right spot.

Sunspots - Wednesday March 27th 2019

Solar flux is 69 and the sunspot number 0 again. A=6 and K=2.

Sorry for the "senior moment " when I thought today was Thursday - now corrected!

26 Mar 2019

2m FT8

Since just before teatime I have been on 2m FT8. So far 17 stations in 3 countries have been spotted on 2m FT8 RX with best DX DK1VC (503km).

On TX (2.5W FT8 to the big-wheel omni) DK1VC (503km) was among the 19 stations that spotted my QRP 2m FT8 signal in 5 countries.
Stations that spotted my 2.5W 2m FT8 
to the omni antenna this evening so far.
2m FT8 never fails to amaze me.

Microwave Round Table

Many years ago I went along to the microwave round table at Martlesham, Suffolk. It must have been a very long time ago. I see that on the programme for this year are talks about gear for Oscar 100 and how to make a GNUradio based transceiver. My health prevents me going these days. It is too far to drive.

Shed cleaning - NOT amateur radio

As it is spring, our son gave our garden shed a bit of a spring clean. He also trimmed a few overhanging branches. As you can see, he took everything out and washed the floor. It looks much better now. An added bonus is you can now see the floor! 😏

70cm activity contest results

Every month the RSGB organises an activity contest on 70cm on the second Tuesday of the month. Although not a great contester (my scores are always way down!) I usually operate with 5W SSB and my 2m omni antenna of about 30-60 minutes. Surprisingly, my position has improved, although unsurprisingly I am still in the bottom half of the AL (low power) section. As I said before, these contests are good in that activity is usually high. These are friendly contests and operators appreciate the QSOs. There is no compulsion to send in a score. Just enjoy the activity.

10m FT8

Well, no surprises so far here.

Although I have been on 10m FT8 since about 0955z, calling CQ (2.5W) initially, no spots at all so far given or received. If things are like yesterday, I may get a few G spots and not much, if anything, else.

At least I am on 10m FT8 RX, so if there are any decent openings, I have a chance. I know my antenna could be better. 10m often surprises me and others. We live in hope! 😊

UPDATE 1110z: No 10m FT8 spots as yet.

UPDATE 1545z: Just 2 10m FT8 spots today with best DX DO8WA (499km) at lunchtime. Pretty poor here.

Constitutional crisis - NOT amateur radio

One thing the whole of the UK can agree on is we are in a right mess. The UK Government seems to have made a right mess of negotiating BREXIT and the UK parliament has wrestled control of the process. The UK Prime Minister seems powerless now.  I think she will resign this week.

Although another referendum seems unlikely, it would no longer surprise me if a majority would now vote to stay in the EU.  The EU has many faults though.

As someone once said, if you were a turkey would you vote for Christmas?

160m FT8 RX overnight

Another good night with 19 North Americans and 1 Caribbean station spotted among the 448 stations spotted on 160m FT8 using the earth-electrode "antenna" in the ground in the last day. Best DX was K4MM (7029km) in Florida, USA.

25 Mar 2019

160m FT8

As 10m was not doing much, on my set-up at least, I have now QSYed to 160m FT8. At first I briefly called CQ (2.5W to the earth-electrode "antenna" in the ground), although I am now RX only. The CQ was spotted by M0RTP (116km).

UPDATE 1706z: No spots yet on 160m FT8 RX, although the sun is still well up.

UPDATE 1722z: Just a couple of Europeans spotted so far on 160m FT8 RX.

OFCOM annual plan

OFCOM has published it annual plan. Great. I am so excited. 😆

Misunderstanding - NOT amateur radio

In 2013, I suffered a brain bleed that has left me with hidden disabilities. On my feet I am permanently exhausted. My voice is poor. Doing anything physical or mental and I am exhausted after about 20-25 minutes.  I am convinced that no-one, really no-one, really understands how I feel inside.

Outwardly I look well. Many think I am fully recovered. It takes a lot of energy to look and behave "normally", so I have a great deal of sympathy with people who appear well, but are not.

Fewer shortwave broadcast stations

Today Southgate News reports on more shortwave broadcasters closing, this time in South Africa. I guess more broadcasters are turning to the internet as it is probably cheaper and more reliable.

I guess this means more shortwave spectrum for amateurs potentially, but the nature of the shortwave broadcast bands is changing. In 20 years a casual tune from 3-30MHz will sound quite different, assuming the manmade QRM is low enough!

It would not entirely surprise me if OFCOM released the entire shortwave spectrum at a limited power level on a non-interference basis.  This could happen within 5 years. Increasingly, people are deserting shortwaves as too unreliable, which suits amateurs perfectly. Maybe they will release spectrum on something like the FCC's Part 15 rules.

10m FT8

As of about 0950z I went on 10m FT8. As yet, no spots. I called CQ (2.5W) briefly, but no spots.

UPDATE 1020z: No spots so far today here on 10m FT8 RX.

UPDATE 1319z: Still no 10m FT8 spots today.

UPDATE 1558z: Just G0OYQ (177km) is the only 10m FT8 spot so far today.

UPDATE 1622z: G4YBI (83km) also spotted on 10m FT8. I shall soon be QSYing to 160m FT8 RX.

160m FT8 RX

Yet again, 160m FT8 was good. As reported yesterday a VK4 was spotted that I believe was genuine. 15 North Americans, 1 Caribbean and 1 South American were spotted overnight with a total of 449 stations.

At 160m, I think the earth-electrode "antenna" acts as a loop antenna in the ground, although the propagation is by normal means. At higher frequencies the loop get progressively less effective. At 160m I am surprised how well it works. It exceeds expectations.
Overnight on 160m FT8 RX

Lackford Lakes - NOT amateur radio

You'd probably class me as a fair weather bird watcher. Yesterday my wife and I went to Lackford Lakes, Suffolk, which is on the edge of the River Lark. I am sure that with patience a lot could be seen. Sadly, we are not patient. The best we saw were a couple of snipe. On the way home there were a couple of kites overhead.

Cycle 25 predictions

It is a brave person that predicts the size of the next solar cycle peak, when some are still predicting the next minimum in 2023!

Recent data may suggest we are already through the minimum, but this could just be a blip. A recent Nature article suggests a peak for Cycle 25 that is slightly bigger than the last peak. Who knows? As time goes by, no doubt the predictions will get better. After the next peak, they will be 100% accurate! 👍

Sunspots - Monday March 25th 2019

Solar flux is 75 and the SSN 22. A=7 and K=0.

24 Mar 2019

160m FT8 RX

As well loads of Europeans, VK4CMV (16366km) spotted on 160m FT8. At first I dismissed this as a pirate, but see he has been spotted by a couple of Australians and New Zealanders, so probably is genuine. If genuine, this is by far the furthermost I have ever spotted on 160m FT8 or indeed by any mode. The time, I think, looks right.

Swallows - NOT amateur radio

From my Facebook memories of 8 years ago, I see I saw a returning swallow in Devon on March 24th.. In some countries, these are known as barn swallows. I usually see the first over here in East Anglia from April 7th, although it is usually a few weeks later before they are commonly seen. Swifts are rare here before the end of April.

10m FT8

At about 0915z, I went QRT on 630m WSPR and QSYed to 10m FT8 RX. Later in the day I may try a few CQ calls.

If it is like yesterday, I am unlikely to spot much. Anyway I am on 10m FT8 RX should you want to try to be spotted. It might be interesting to find out how successful some Gs are. Can I spot you?

UPDATE 1320z: Quite a surprise! Already 8 stations spotted in 5 countries. Are we seeing some signs of Es?

UPDATE 1744z: 12 stations in 7 countries spotted so far today on 10m FT8 RX. All Europeans, but better than of late. Soon be time to QSY. Probably to 160m FT8 RX.

472kHz WSPR overnight

For the first time this "season" I was spotted by more stations than stations that I managed to spot. Usually I spot more than spot me. My best spot was by Finbar EI0CF (602km).

People's vote march - NOT amateur radio

Although we may argue about just how many attended the London march yesterday, there were a lot. In the end, I suspect the UK parliament may take over BREXIT and a compromise, acceptable to a majority, will be worked out. We are in odd times. I hope that rifts can be mended.

See https://www.bbc.co.uk/news/uk-politics-47678763 .

Meaningful vote (take 3) - NOT amateur radio

It is rumoured that the UK Prime Minister, Mrs May, will try for a 3rd time, to get her BREXIT deal approved by the UK parliament.

Most in the UK are sick to death of her "flogging a dead horse".  In the end people will lose faith in her and tell her to listen rather than continue with a deal that will only get approved if people see no other alternative.  Personally, I think she will resign within 14 days.

In recent days she has managed to alienate people who voted "leave" and "remain" in the 2016 referendum. If there was a real leader in the wings I'd say go, but we seem bereft of decent leaders.

Ducks - NOT amateur radio

On a walk around the village yesterday we spotted these 2 ducks sleeping next to a car. I suspect they were just "chilling out" whilst they waited to be fed in someone's garden. Pretty sure these are semi-domesticated mallards. They certainly are a long way from wild mallards!

Sunspots - Sunday March 24th 2019

Solar flux is 79 today and the sunspot number 27. A=1 and K=0.

G3RJV (SK) - Mr QRP

Yesterday I received my Spring 2019 copy of SPRAT, the excellent GQRP quarterly magazine.

On the cover was a picture of G3RJV with fellow QRPers G3MFJ and G3VTT. This was taken in a care home and George G3RJV looked frail and thin, a shadow of his old self. The magazine was obviously prepared before he died.

G3RJV was an inspiration to me and many others. RIP George. We shall miss you, but carry on with QRP. You were a beacon to many of us.

472kHz WSPR

A few minutes ago I QSYed to 472kHz WSPR (10mW ERP, 20% TX, 80% RX). Even though the transverter crystal is still settling, I have already received a spot from G8LCO (58km).

Nest building time - NOT amateur radio

We get lots of pigeons these days. Earlier, I noticed a pair busy building a nest in our garden. This one is gathering twigs.

10m FT8 RX

Since 0837z, I have been on 10m FT8 RX.  No spots yet at 0941z.

UPDATE 1100z: Still no 10m spots today.

UPDATE 1403z: Just a couple of G spots so far today on 10m FT8 RX.

UPDATE 1618z: A disappointing day here so far with just 3 G spots all day. No DX and not even a European spotted. I must erect a better 10m antenna before the Es season, although the antenna I have would probably be fine for Es. If the minimum is really ending 10m could be quite a bit better by next spring.
