6m JT65

At the moment I am not on 10m WSPR, but I am on 6m JT65. So far, just G stations and no Es on 6m seen here. Of course, it is still early and things could well change.

UPDATE 0934z: 6m JT65 spots of me from Serbia and Romania, which look like Es.

UPDATE 1235z: EA9IB in Ceuta and Melilla, N. Africa (1907km) spotted on 6m JT65.

UPDATE 1514z: Mostly EU Es spots on 6m today, apart from EA9 (N.Africa) earlier. Iceland counts as Europe.

Burwell Museum and Windmill - NOT amateur radio

Our local windmill and museum (right next door!) is one of the very best local museums in the whole of the UK. It is open 11am-5pm every Thursday, Sunday and Bank Holiday from Easter until late October. It is huge and is spread over many buildings. It goes on and on! When my grandchildren can't go they cry. For a few hours out, it is well worth a visit if you are in the area.

See http://www.burwellmuseum.org.uk/ .

Sunspots and 10m - Sunday June 25th 2017

Solar flux is little changed at 74 today. Sunspot number is 28. A=9 and K=2.

Windmill in summer - NOT amateur radio

This is the view up the lane to "our" 200 year old windmill. On the left is an ornamental cherry tree.

6m JT65

So far today on 6m JT65 transceive, there has been a lot of Es across Europe, but nothing further apart from EA8DRM (3015km) in the Canary Is.

UPDATE 1948z: AA4V (6544km) in South Carolina was spotted. Judging by other spots, I am pretty sure this is genuine.

Convolvulus - NOT amateur radio

This is often known as bind weed. In the garden it is a nuisance, but it has nice flowers and looks good in the wild as here.

Need for 472kHz antenna improvements

Although these days I am very dependent on help with antenna work because of my stroke, I very much hope I can try a better antenna on 472kHz WSPR this autumn and winter. I have been surprised how well the earth-electrode "antenna" works, but another 10dB ERP would be really worth trying. I have in mind a long-wire, which needs a support at the end of the bungalow. I also need a better earth system.

My homebrew transverter for 472kHz puts out about 12W. With a better antenna an ERP around 50-100mW should be possible. At the moment, my 472kHz ERP is around 5mW.

Low storm risk

It is very unlikely my amateur radio activities will be interrupted by storms today. The nearest storms are way to the south. This morning we have had a few dark skies, but no rain.

Virtual Amateur Radio

I have to confess, I have not tried "virtual" ham radio for many years. It is a poor substitute for the real thing. Even with my poor voice these days, the real thing offers so much more. Nonetheless, it will appeal to some, especially when HF conditions are poor.  I expect this will become more popular in the next few years. As it name implies, virtual ham radio uses the internet rather than the ionosphere as the medium of "propagation". If all you want is to chat, this may be for you.

Sunspots and 10m - Saturday June 24th 2017

Solar flux is 73 again today. Sunspot number is 22. A=5 and K=1. I am not currently on 10m, but there is Es already on 6m.

Rally this Sunday

25 JUNE 2017 : WEST OF ENGLAND RADIO RALLY

Cheese & Grain venue, Market Yard, Bridge Street, Frome, Somerset BA11 1BE. Doors open from 10am to 2pm with admission priced at £3 for adults and children under 14 free.

A list of rallies can be found at http://rsgb.org/main/news/rallies/

Low storm risk in the UK

With the nearest storms being in Austria, I think I can safely "play radios" today.
 Just I case, I'll keep and eye on the maps.

See https://www.lightningmaps.org/?lang=en#y=53.2284;x=-3.9585;z=5;t=3;m=sat;r=0;s=0;o=0;b=0.00;n=0;d=2;dl=2;dc=0;

Where I was born - NOT amateur radio

The picture shows where I was born in Devon, UK when a nursing home after WW2. The film "Sense and Sensibility" was, in part, filmed on the Flete estate. This is Flete House. These days they are posh retirement flats.

Not much Es on 6m JT65 yet

I have been on 6m JT65 for some time. No Es seen yet today on 6m, although I am supposed to have spotted a station in Indonesia on 6m, which I do not believe. This suggests the pirate is in the UK. Sad.

UPDATE 1045z: Some Es with my 1W ERP 6m JT65 being spotted in Finland.

Sunspots and 10m - Friday June 23rd 2017

Solar flux is 74 today and the sunspot number 23. A=6 and K=1. 10m? Expect Es but F layer N-S is more doubtful on 10m.

ICOM IC703

Until I sold mine to a local fellow ham several years ago, I used this rig most days. They are hard to find now, and I am not surprised. In many ways I regret selling mine, but it went to good home and is well used.

Sadly, there is no real equivalent QRP rig outside of Japan. The IC7300 is probably the nearest, modern rig, but the 10W version is only available in Japan. If the 10W version was available in the UK, I would buy one, as I suspect would many.

The IC703 is a 10W 160m-6m multi-mode transceiver with an auto-ATU. It has a good DSP filter. Altogether a good, solid radio.

See https://sites.google.com/site/g3xbmqrp3/hf/ic703

VLF transmitters

Recently I had an email asking me if stereo amps (100W) would make a suitable VLF TX. The short answer is "yes", although these are designed for a low impedance load, so would require a suitable matching transformer. I have not tried one.

Storm gone, so back on 6m JT65

The storm has passed through, so I have returned to 6m JT65 transceive (1W ERP). I tried replying to a few CQ calls, without success, so I am currently in beacon mode sending "B G3XBM JO02". Best report is from CT2IWW (1382km). There seems less Es about at the moment.

UPDATE 2038z: As well as spots of OX3LX (2570km) which I do believe, I also (supposedly) spotted another Indonesian station, which I do not believe: I am convinced this is a pirate somewhere in Europe. Unless proved otherwise, I am dismissing these latter spots.

Storms, so QRT

Although the weather forecast showed no risk, there is thunder close by, so I have disconnected antennas and power and gone QRT. I have found the weather forecasts very poor.

See https://www.lightningmaps.org/?lang=en#y=52.5523;x=-0.4813;z=7;t=3;m=sat;r=0;s=0;o=0;b=0.00;n=0;d=2;dl=2;dc=0;

UPDATE 0852z: The forecast says less than 5% of rain. Guess what? It has just rained!

Youngsters and amateur radio

This is a point I have made many times: unless we attract young people into our hobby and keep their interest, it will die with us. I see on Southgate News that the ARRL has been doing something about the growing crisis.

See http://southgatearc.org/news/2017/june/amateur-radio-needs-young-people.htm#.WUuA4LpFzmQ

Sunspots and 10m - Thursday June 22nd 2017

Solar flux is 73 and sunspot number 35. A=4 and K=2. 10m? No idea, but Es should be decent especially later.

Pound against the Euro - NOT amateur radio

It is a year this week since the UK voted to leave the EU. I voted to remain.

It is my view that the Euro will lose value soon, probably this year. The UK was a major contributor to the EU finances and we will be missed. The Euro problems have not gone away, particularly Greece. Yes, the UK may be hurt in the short-term, but I cannot see this lasting.

Despite BREXIT, I am expecting the UK pound to gain value against the Euro, possibly as soon as this year. As I have said before, I could be completely wrong!

Storms?

For about a week now it has been very hot indeed for us. Today could be the hottest June day ever. Please someone tell the president of the USA. No, global warming is not a Chinese hoax. Just look at the real data.

Tomorrow, the weather could break with a return to more usual June weather here in the UK. With heavy thunder and lightning, maybe tomorrow will not be a good day to play radios? I shall be watching the maps.

See https://www.lightningmaps.org/?lang=en#y=52.9182;x=-3.2938;z=5;t=3;m=sat;r=0;s=0;o=0;b=0.00;n=0;d=2;dl=2;dc=0;

Market fruit and veg - NOT amateur radio

Bury St Edmunds, Suffolk. Market Day and lots of fresh fruit and veg on sale. Excellent. Bury is an "old fashioned" sort of place, but excellent for shopping. Great market still with some great bargains e.g. 3 magazines for £2.50 on one stall and they are only a few weeks old too.

Yesterday on 6m JT65

Yesterday was a good day on 6m JT65.

Stations were spotted in North America, South America and the Caribbean. I have dismissed the Indonesian spot as a pirate unless I am proved wrong.

At the moment, I am on 6m JT65 in beacon mode with 1W ERP. There is plentiful Es on 6m with spots (RX and TX) all across Europe.

UPDATE 1315z: Now RX only on 6m JT65.

UPDATE 1750z: Enabled 6m JT65 TX a few minutes ago.

Sunspots and 10m - Wednesday June 21st 2017

Solar flux is 73 today and the sunspot number 34. A=3 and K=1. Although there is 10m and 6m Es, it is some while since I noted 10m F2 here, although my 10m antenna is not great.

ICOM and Yaesu UK Prices

The IC7300 from ICOM retails at just under £1200 in the UK. The Yaesu FT891 retails for about half this at just under £600. OK, I know they are different radios, but both are 100W HF and 6m radios and the RX of the IC7300 has a much simpler SDR architecture.

Although I accept I may be wrong, these are my conclusions:

• The IC7300 sells at a price people are prepared to pay and dealers are keeping the price as high they dare for as long as they can. It almost looks like the price is fixed between dealers. I am not saying it is, but it looks like this. Normally by now one has started to drop price, but this has not happened. The true price should be far less.
• Yaesu sells the FT891 at just under £600 to tempt buyers. They may be trying to buy market share. I note a new model Yaesu 2m/70cm handi sells for £129.

Looking at this, I'd guess that ICOM will be around for a while. Yaesu may decide this is not a market to remain in for too much longer? As I said, I could be totally wrong. Personally I hope both stay in the amateur market for a long time.

Sunspots and 10m - Tuesday June 20th 2017

Solar flux is 73 today. Sunspot number is 26. A=5 and K=1.

This year has flown by! It is hard to believe we are so close to the longest day and soon nights will start to lengthen.

Lots of Es about on 10m and 6m.

10m WSPR TX

As usual, I am active on 10m WSPR TX (500mW). Lots of Es spots. 30 unique spots in the last 12 hours.

6m JT65 real DX - real and fictional?

Just spotted K1TOL (5082km) in Maine, USA on 6m JT65.  I am sure this is true having worked this well equipped station some years ago on 6m CW.

Also, I spotted (supposedly) yet another Indonesian on 6m JT65. I have lost count of the number of Indonesians on 6m JT65. Unless proved otherwise, I think these are false decodes or pirates.

UPDATE 1600z: WP2B (6804km) in the US Virgin Islands in the Caribbean was spotted earlier. Judging by others who also spotted him, I think he is genuine.

UPDATE 2055z: PV8DX (7830km) in northern Brazil is the latest 6m JT65 DX earlier this evening.

10m WSPR TX

As the 500mW 10m WSPR beacon was looking lonely, I decided to turn it on earlier this afternoon. So far, Es spots in northern Spain and Austria on 10m WSPR.

Another hot day ahead - NOT amateur radio

This is a surprise! For a second day in a row, we had breakfast in the garden. It is already hot. For us in the UK this is exceptional. Even in the shade it was warm even at 8.30am. My wife as just been for a walk and says it is very hot.

Just 6m JT65 today

At the moment, 10m WSPR is proving too easy! Most days, my 500mW is spotted across Europe, so today I am just on 6m JT65 transceive.

Sunspots and 10m - Monday June 19th 2017

Solar flux is 74 and sunspot number 27. A=10 and K=2. There is already Es about.

Geostationary amateur satellites

We are used to geostationary satellites which carry TV signals from a fixed point: aim the dish in the right place in the sky and that is it. By contrast, amateur satellites are in a low and moving orbit, so they only stay in range for a short time and they have to be tracked in the sky.

All this could change next year when 2 satellites (containing amateur radio transponders) are placed in geosynchronous orbits. Aim your antennas once and fix them in place. A lot can go wrong - date slippage, failure on launch, failure to reach the right place in space, equipment failure etc. If these all go to plan, amateur radio could be quite different in a few years' time.

As we are approaching a period of very poor HF conditions, these satellites could be a godsend. One is aimed to give good coverage over the Americas. The other covers Europe, Middle East and Africa mainly.

Old FT817

Looking through some old photo albums, I spotted me with an FT817 in the garden dated 2001. This means I first bought the FT817 at least 16 years ago. I was probably working OX (Greenland) at the time, with 2.5W and a telescopic whip on SSB. It seems amazing that it has been around all that time with effectively no competition.

Another thing that struck me was how young and thin we looked back then!

10m WSPR

As usual, I am on 10m WSPR TX (500mW) with my WSPR beacon. Plenty of Es spots from across Europe today.

UPDATE 1314z: 20 unique spots of my 10m 500mW WSPR so far today.

UPDATE 1640z: 59 unique spots of my 10m 500mW WSPR in the last day (34 in last 12 hours).

UPDATE 2008z: 52 unique 10m WSPR spots of my 500mW beacon in last 12 hours - a good day. Going QRT shortly on 10m.

House martins (birds) - NOT amateur radio

A few days ago I saw my first house martins this year in the UK. This is much later than usual, so I wonder if numbers are down? These were in a nearby village. I've seen none in our village this year.

There seem to be plenty of swifts  - there were about 20 feeding overhead last evening - but house martins and swallows seem to be fewer this year. This may be a localised thing, but I notice numbers seem down.

Anyone know the facts?
