Solar data for February

Data for February is now available.

Although we are on the long fall to the next solar minimum, there was a small rise in solar activity last month. This is a blip on the slow decline, but serves to remind us that there are good days as well as bad days. Even now there are days with real DX on 10m.

See http://www.solen.info/solar/ .

Endings - NOT amateur radio

I am not good at endings. Life goes on normally, then something happens to change the routine: things that had gone on for years and taken for granted come to an end. When this happens it is a real shock.

In reality, life is all about coming to terms with change. Change is always happening, yet we are often unaware or not looking. No, we have to accept change and move on. Change is a reality. As they say, "the past is another country". Enjoy things while they are there, accept them, and then move on. Change is part of life, whether we like it or not. For some of us this is hard.

Sunspots - Sunday March 4th 2018

Solar flux is 67 today and the sunspot number back to zero. A=6 and K=2.

2m FT8 RX (again)

This is getting addictive! Again, I am monitoring 2m FT8. In the last 6 hours 6 unique stations in 3 countries with best DX F6EAS (387km) in Normandy. Again I am using my big-wheel horizontal omni antenna. Gain is about 2dBd.

UPDATE 1030z: Already 14 uniques in 3 countries.

UPDATE 1400z: Now 24 uniques in 5 countries in the last half a day on 2m FT8 RX. I can honestly say that 2m FT8 has been a revelation. Every day seems to result in spots of stations at great distance, even though my antenna is nothing at all special and with hardly any gain over a dipole. Imagine the results with a 9 element beam!

UPDATE 1430z: Now 28 uniques in 7 countries on 2m FT8 RX with best DX DK2DTF (644km).

UPDATE 1622z: Now 30 uniques in 7 countries today on 2m FT8 RX.

UPDATE 1905z: A local friend G3TFX has suggested I try vertical polarisation to see how much difference this makes, especially with DX signals. If tropo, I'd expect about 15-20dB polarisation loss. If aircraft reflection, the difference should be far less. The overall gain of the big-wheel with feeder loss is probably about 0dBd. The feeder loss and gain of my V2000 vertical is probably much the same. So, tomorrow I'll try 2m FT8 RX with vertical polarisation.

Eddystone Receivers

When I first got interested in the hobby in the early 1960s Far Eastern transceivers were unheard of. Many used war surplus receivers like the AR88 or CR100. For years I coveted an Eddystone EC10. One day I got one. The IF was low and the bandspread on 10m was abysmal! As a tuneable IF for VHF and UHF converters it was fine. Overall, it really was not a very good receiver. These days they are hard to find and really not worth the money.

The 840C was a much better radio. At one time they even did an amateur band only receiver called the EA12.

Slapton Line - NOT amateur radio

This is also known as Torcross Line, Devon. In WW2 is was used as a place where D-day landings were rehearsed.

Sadly, a big stretch of the road along it was washed away and it is quite possible it will never be repaired. In the end the sea will inundate the freshwater lake known as Slapton Ley. This could be soon or in 50 years' time.

The question is how long do you keep re-building the road (A379) that runs along it? This stretch is one of the best views in the UK.

Online shopping - NOT amateur radio

Shopping online is quite common these days. I have successfully bought lots on line. However, it is not always a good story.

Recently I bought a couple of batteries for my watch via Amazon. Usually these last several years but one failed after a month despite it being a branded item. Cost-wise I probably saved several pounds even so. The second battery is still working fine.

I also bought a spare head and cutters for my electric razor. Even after a few months they struggle to cut, whereas the originals lasted years.

All I am saying is caveat emptor. Most things will be inexpensive and work fine, whereas some things may be problematic.

50 years - NOT amateur radio

It seems hard to believe, but my wife and I first met 50 years ago today.

Looking back, I just wonder where those years went. Even today, knocking on the door of 70, I still feel in my late teens inside. All I can advise is milk life, as it soon slips through your hands.

Time is an odd thing. On the one hand it seems to pass slowly, whereas on the other hand it passes all too fast. One thing is certain: we will not get another 50 years!

Sunspots - Saturday March 3rd 2018

Solar flux is 67 today and the sunspot number 11. A=4 and K=1.

2m FT8 RX

Although I am monitoring 2m FT8 RX again, there have been no spots so far today. Perhaps we have had a lift in the last few days and things are returning to normal?

UPDATE 1030z: An FT8 QSO on 2m with G8ALS (127km) and PA4X (403km) spotted in Limburg. Perhaps it was too early!

UPDATE 1126z: Now spotted 15 uniques in 3 countries. I had a QSO (2m FT8) with David G0LRD (26km) when he was using 1mW and good copy on the big-wheel. He was -21dB on a 3el in the loft with 300uW!!

UPDATE 1350z: Now 30 uniques in 5 countries.

UPDATE 1730z: Now 39 uniques in 7 countries.

UPDATE 2030z: The photo shows the stations spotted here on 2m FT8 in the last 12 hours.

South Devon Storm Damage - NOT amateur radio

As some may remember, I come from the South Hams, Devon.  In the recent bad weather a lot of damage has been caused along Start Bay. My niece sent me some links. In 50 years' time the coast will be very different, probably not in my lifetime, but almost certainly in the lives of my grandchildren.

2m big-wheel antenna

For a couple of years now I have used a big-wheel horizontal omni antenna on 2m. This is the antenna used in the last few weeks on 2m FT8. It has a near omni-directional horizontal pattern, a little bit of gain and, of course, does not need a rotator. It is ideal for my sort of 2m operation.

See https://sites.google.com/site/g3xbmqrp3/antennas/bigwheel

The linked page needs updating and this is on my "to do" list!

Sydney-Sussex College - NOT amateur radio

Although I have said this before, it is worth saying again. Living just outside Cambridge we get rather blasé about some of the sights in the city. One, small, example is Sydney-Sussex College which I pass twice a week. Every college is a delight.

Portable power

Southgate News has details of OH8STN's QRO power pack for portable use.

See http://southgatearc.org/news/2018/march/diy-qro-lifepo4-power.htm#.WpkfKkx2vIU

FT818 disappointment

It is hard to express my extreme disappointment with the FT818. Auto ATU? No. Speech processor? No. Lithium Ion batteries? No. And on and on. This is a development done on the cheap by a company that looks to be in trouble.

Recommendation? Do not waste your money, unless (like the FT991A) they have second thoughts and produce a 21st century transceiver we deserve.

Yaesu - what the heck were you thinking? This is crap.

Sunspots - Friday March 2nd 2018

Solar flux is 67 and the sunspot number 11. A=6 and K=2.

2m FT8 RX - Friday

In just the last hour alone 5 unique stations in 3 countries with best DX F6EAS (387km) in Normandy.

UPDATE 0953z:  In the last 2 hours, 9 uniques in 4 countries.

UPDATE 1055z: 19 uniques in 5 countries on 2m FT8 in the last half day.
UPDATE 1143z: Now 24 uniques in 6 countries!

UPDATE 1552z: 34 uniques in 7 countries now.

UPDATE 1727z: 39 uniques in 7 countries.

1 Mar 2018

2m FT8 RX

About 10 minutes ago I moved to 2m FT8 RX. It seems quite busy.

UPDATE 1540z: Best DX on RX is DF8JO (535km). In just 20 minutes I have spotted 11 unique stations in 3 countries!

UPDATE 1810z: 20 uniques now in 4 countries.  Amazing with an omni antenna.

UPDATE 2030z:  Now 26 uniques in 4 countries.

Rally

As the weather is not good I urge you to contact the organisers of each rally before travelling. Some could well get cancelled if the weather is bad.

Yaesu FT818

Sorry, but I have no further news of this transceiver. All I can say, again, is that the very future of Yaesu rides on this, in my view.

If it turns out to be just a minor upgrade to the FT817 then I expect Yaesu to be dead in the amateur market within 5 years. This has to be something exciting. From the early press releases, this does not look anything special. As a loyal Yaesu fan for almost 40 years I desperately hope I am wrong.

Only the FT817ND (not the FT818) is mentioned on the Yaesu, Japan website.

See http://www.yaesu.com/jp/en/products/pdf/Amateur2011_EN_1104.pdf

M0PNN has provided a link - thank you - https://www.yaesu.com/indexVS.cfm?cmd=DisplayProducts&ProdCatID=102&encProdID=36B7B98621AF7554C9A03C8B190C5079&DivisionID=65&isArchived=0

From what this says, I reckon Yaesu is doomed if this is the best they can do. I for one will not be buying one! What a pathetic offering. Back to the drawing board, or is it the Japanese equivalent of administration in 2019?

Overnight on 630m WSPR

Overnight was disappointing on MF. In all, 15 unique stations spotted, so no more than I received last evening. Again, all were EU with none from the USA.

I may try a different band tonight for a change.

Sunspots - Thursday March 1st 2018

Although we are at the start of meteorological spring, it still feels very much like winter with snow and bitterly cold winds.

Solar flux is 70 today and the sunspot number 11. A=6 and K=1.

10m FT8 RX

Although I have been on 10m FT8 RX since before breakfast, all is quiet with no spots here. Others with better setups may be more lucky.

UPDATE 1600z: No spots at all here all day so far. About 20 minutes ago I tried a CQ call, but no-one spotted me sadly.

28 Feb 2018

630m WSPR RX this evening

For most of the evening I have been on 630m WSPR RX. So far, 15 unique stations have been spotted, which is quite good for this time. As the shack PC battery is almost fully charged, I shall be looking almost until breakfast. I am surprised not to have spotted a single USA station when most EU stations are being copied on the earth-electrode "antenna".

Snow showers - NOT amateur radio

Most winters these days are mild. This has been the exception with quite a few frosts. Today we have about 3 inches of snow (6-8cms). It has been snowing on and off much of the day. At the moment it looks nice.

The EU and BREXIT - NOT amateur radio

So the EU has published its draft bill on the UK leaving the EU. Since it was published, the UK pound has lost value against all major currencies. No doubt it will recover, but at the moment the UK seems to be fumbling around over what it really wants once we leave.

Why did we not say the referendum would not be binding unless the majority was x %? As it is the margin of "leave" over "remain" was a small 4%, with almost a half not wishing to leave the EU. I suspect fewer would vote leave now. Many want controls over immigration but still want the tariff-free trade with the EU.

UPDATE 2152z: At the end of the day, the UK pound was 0.76% weaker against the euro

Maplin administration

Allegedly, Maplin has gone into administration.

I was in a company that went into administration many years ago. It is very unpleasant as it means your pensions and severance deals can count for nothing. I expect the administrators are trying to find a buyer for, at least some of, the stores.

Sadly, Maplin is another example of the way we shop now. Fewer go into stores and more and more of us buy online at lower prices, often from the Far East with free postage.

As I have said many times, those that adapt have some chance, whereas those that do not adapt will fail. I suspect those that will survive have a good online store and a high street chain to allow browsing. John Lewis comes to mind.

See http://www.bbc.co.uk/news/business-43223175 .

Amazon failure - NOT amateur radio

As part of my wife's Christmas presents I ordered a CD from Amazon on Nov 11th 2017. Despite many new dates it has still not arrived.

If this was a rare CD of Mongolian folk music I could understand this, but this is a very simple CD of common music. I am still struggling to understand why this should take so long.

In this time (nearly 4 months) this could have been handmade in China! At the very least "a human" (these seem in short supply) could have said they cannot get it, sorry. As it is, they are still trying to get it.

Maybe Christmas 2019?

OFCOM and short range devices

Today, OFCOM published a new document about short range devices.

I have no idea if this affects the access by amateurs to different parts of the radio spectrum, but I think not. OFCOM would have to think, and make decisions. Surely not possible!

Like many OFCOM documents it looks like it was written by a 1st year Law student who hides behind the law as he/she knows nothing about RF. If I am being grossly unfair, I am sorry, but that is how I read it.

See https://www.ofcom.org.uk/__data/assets/pdf_file/0023/111677/Implementing-the-Commission-Decision-on-Short-Range-Devices.pdf

Still snowing - NOT amateur radio

As I write, it is still snowing here. This is the heaviest snow we have had for several years. Definitely a day to stay at home and keep warm!

WRC-19 and amateur radio

The next World Radio Conference is next year (2019). At it, spectrum will be discussed. I have to admit that I have not been following preparations too closely, but I expect the amateur service will be way down the list of priorities. Much more important to the national administrations will be spectrum for satellite services and for 5G. Basically, if it generates money they will be interested. If not, it will play second fiddle.

For the amateur service what would I like to see?
  • Extension of the 5MHz allocation made at WRC-15.
  • A 4m band throughout region 1 (possibly elsewhere too).
  • A 6m band everywhere 50-52MHz minimum (50-54MHz ideally).
  • Clarification that spectrum below 8.3kHz can be used by anyone anywhere on a non-interference basis.
  • Access to 40MHz and 60MHz for Es research. Even a very small allocation would be useful.
Now, probably most of these will not happen!

10m FT8 RX

At the moment, I am monitoring 28.074MHz FT8 RX. Realistically, I am not expecting great things, but I have been surprised in the past.

UPDATE 1025z: No spots as yet.

UPDATE 1347z: Just spots of G4CJC (73km) in north London so far.

UPDATE 1654z: SQ4OJD (1359km) spotted earlier this afternoon. So far the only no-G spotted.

UPDATE 1735z: Now CT1GFQ (1684km) being spotted.

UPDATE 1826z: ZP5FIA (10287km) in Paraguay copied. There is still DX on 10m.

630m WSPR RX overnight

In all, 17 unique stations spotted on 630m WSPR in the last day. Nothing outside of EU, but a couple of new countries for me in the form of 9A3KB (1290km) and HF7A (1294km).

Snow - NOT amateur radio

This is a photo of our grandson enjoying the snow on his birthday. It is still snowing now and this winter has been the coldest for several years.

Sunspots - Wednesday February 28th 2018

Solar flux is 69 and the sunspot number 15. A=19 and K=2.

27 Feb 2018

More on WSJT-X V1.9.0

Southgate News has more information on the latest version of WSPR-X, free software available for download. The FT8 weak signal, narrowband, mode has really "taken off" and has amazed me. The software for this is in WSJT-X and is totally free. All you have to do is sit on a given USB dial frequency and watch the DX appear. QSOs are formulaic, but the mode allows low power to reach great distances. Yesterday for example my 2m 4W ERP was spotted in north Devon quite easily.

See http://southgatearc.org/news/2018/february/wsjt-x-version-1-9-0.htm#.WpXVPkx2vIU

Joining the dots - NOT amateur radio

This may be because I am getting older or an artefact following my 2013 stroke.

Sometimes I mishear things or simply misunderstand and my brain tries to make sense of it by subconsciously "joining up the dots". Sometimes I completely get the "wrong end of the stick". Today, I misunderstood my wife saying an old friend was coming tomorrow afternoon when in fact he was coming this morning. I guess this happens several times a week.

The moral is to make sure I heard correctly and don't interpret things incorrectly. At times my brain plays tricks.

Cambridge bikes - NOT amateur radio

When crossing roads in Cambridge you have to be careful: there are lots of bikes and often cycles are allowed to go down roads against the traffic flow. It is all too easy to walk into bikes. I have the dubious distinction of causing a cyclist to crash off his bike when I was a pedestrian buckling his front wheel. That was in 1971, but the nickname "crash" was still with me well into the 2000s! Cambridge is synonymous with bikes.

630m (472kHz) WSPR RX

If I can successfully download the latest version of WSPR-X (V1.9) I may give 472kHz WSPR a go this evening and overnight.

UPDATE 1422z: Well, it looks like WSJT-X V1.9 rc2 has successfully downloaded and installed. Currently, I am on 472kHz WSPR RX, but no spots yet.

UPDATE 2115z: 10 unique stations spotted so far this evening including 9A3KB (1290km) which is a new country for me on this band. Best DX so far is LA2XPA (1310km). The shack PC is on battery power.

UPDATE 2155z: The shack PC battery is charging until about 2300z. Thereafter, I shall be on 472kHz WSPR RX through the night with the shack PC on battery power. The PC usually stays working until about 0600z.

UPDATE 2310z: Everything is now set up for an overnight look on 472kHz WSPR. Yet again, I am hoping for some USA spots. Well, I can hope. After about 10 minutes, 5 uniques spotted.
