Norwich - NOT amateur radio
Today we went by car to Ely and then by train to Norwich. Norwich is a fine city with a great Norman cathedral and a good market. It is place we like a lot.

OFCOM and gender pay gap
OFCOM has published details of its survey of the gender pay gap.
See https://www.ofcom.org.uk/about-ofcom/what-is-ofcom/corporate-responsibility/diversity-and-equality . It is narrowing, but still there.

472kHz WSPR
10m FT8 RX
Despite the poor solar numbers, I am on 10m FT8 RX after a brief CQ call (no spots).
UPDATE 1740z: Just a couple of G spots today on 10m FT8. Dire!

472kHz WSPR (10mW ERP)
With nothing at all on FT8, I have QSYed to 472kHz WSPR (10mW ERP). G8LCO (58km) has already spotted me.
UPDATE 2300: 4 spots so far of me with best DX PA0O (440km). Interesting again that more stations are copying me that I am copying others. This was the same the last time I was on 472kHz WSPR. It suggests many are leaving the band now that we are in spring. Most DX possible has already be worked, so people are turning to new challenges perhaps?

472kHz FT8 (not WSPR)
As an experiment, I am on 472kHz FT8 (10mW ERP from the earth-electrode "antenna" in the ground). If I spot anyone at all I shall be amazed and if I have a QSO I shall be doubly amazed!
UPDATE 1940z: No 472kHz FT8 spots at all. Assuming nothing changes, I shall move to WSPR at 2000z.

Mother's Day - NOT amateur radio
It seems that our local Waitrose is gearing up for Mother's Day on Sunday. I guess (being a cynic) they see a quick profit.

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.
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.

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.

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.
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!

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.
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.

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.

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.
See http://southgatearc.org/news/2019/march/bloemendal-shortwave-station-final-transmission.htm#.XJircfZ2u00 .

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.

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! 👍

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.
