Crystals sets

A great deal of fun can be had with the simplest of receivers. I had some great fun DXing with a shortwave crystal set. These days, there are fewer SW broadcasters sending in English, so IDing is harder, but not impossible.

10m FT8 RX

So far today, just one spot on 10m FT8 RX of DL8FCK (627km) in Hesse in Germany.

UPDATE 1930z: Just one G spot in addition and no DX as yet today.

UPDATE 2145z: Now QRT.

Worse spots to read? - NOT amateur radio

This was our granddaughter earlier reading on our windowsill. There are worse backdrops!

I think this is a book she brought from home.

Sunspots - Wednesday April 11th 2018

Solar flux is 68 today and the sunspot number remains zero. A=20 and K=2.

10m FT8 RX

As well as a couple of stations in Rio (Brazil) I also spotted VP8LP, although these spots of the Falklands did not upload to PSKreporter.  It seems that 10m regularly opens to South America, despite the very poor solar conditions. It is definitely worth keeping a watch on 10m FT8. Quite a few EU spots plus 3 in the Canary Is.

70cm (432MHz) UKAC RSGB activity contest

Tonight I expected to miss this contest as we have grandchildren staying. I managed to snatch about 10 minutes and worked a couple of stations with G4CLA (105km) as the best DX. Seeing I only have 5W RF and a 2 metre halo, I was quite pleased.

Museum visit - NOT amateur radio

It is funny, but our grandchildren seem to love museums! Today we had to revisit the small (free) museum at Mildenhall, Suffolk. We also had a request to visit the church there again.

Yet more OFCOM rubbish (my view)

Now we are told that the next stage in their auction of microwave spectrum has been reached. Big deal. Most of us are just plain bored.

You can also read this in Welsh. It is a good job green people with one leg living in Stoke-On-Trent don't have their own language or they'd have to employ another person!

2m FT8

After a quick CQ in which my 5W to an omnidirectional antenna was received by G0LUJ (279km) I shall be on 2m FT8 RX most of the day. I may try 10m FT8 much later.

As yet,  just a couple of Gs spotted on 2m FT8.

UPDATE 0918z: Now 3 Gs spotted.

UPDATE 0930z: Now one F and DK spotted. Best DX is F6APE (551km).

UPDATE 1148z: Now 24 unique stations in 4 countries spotted today on 2m FT8.  Best DX is DK2DTF (644km).

UPDATE 1605z: Now 45 uniques. Time to QSY to 10m FT8 RX.

The Pixie

This is a classic QRP CW transceiver. Like all simple transceivers it is a compromise. Chinese versions are available at less than the cost of the crystal alone in the UK. The Chinese kit I built was for 40m and worked first time.

The Pixie is a derivative of the Micro-80.

Simple Regen Circuit

Regen receivers amaze me. How something so simple can work so well never fails to intrigue me.

I was looking for a photo I took some years ago, but so far I have failed to find it. I still have the RX in a drawer!

Sunspots - Tuesday April 10th 2018

Solar flux is 69 and the sunspot number 0.  A=10 and K=2.

Soloists - NOT amateur radio

At my wife's concert one of the soloists was sick, so at the very last minute he was replaced.  Thankfully he was excellent.

See www.cambschoral.org.uk

10m FT8 RX today

As usual these last few days, I have been keeping an eye open on 10m FT8 RX. So far today, just G4CJC (74km) spotted. No EU stations spotted yet and no DX.

UPDATE 2019z: As well as a an Italian, PY1SX (9301km) spotted.

Sunspots - Monday April 9th 2018

Solar flux is 68 today and the sunspot number still zero. A=5 and K=2.

Wife's Concert - NOT amateur radio

My wife's concert in Cambridge was last night. Here is a picture.

Sunspots - Sunday April 8th 2018

Solar flux is 67 today and the sun remains spotless.  A=5 and K=2.

10m FT8 RX

This becoming a habit! It is now 3 evenings in a row that South Americans have been spotted on 10m FT8, despite zero sunspots and really low solar flux. FT8 is catching brief openings.

I am on again this morning, but just EUs spotted so far.

UPDATE 1115z: Still just a few EU stations with best DX F4DJK (779km).

UPDATE 2120z: First day in 4 days with nothing outside Europe today. Best DX spotted was EA1EU (1005km).

SW BC interval signals

I know this has been posted before, but it is quite good to hear some of these again. If you are like me, your first introduction to amateur radio was via shortwave broadcast signals. Shortwave is quite different these days with far fewer English language broadcasts. It is no longer the magic it was to oldies like me!

Yours truly yesterday - NOT amateur radio

This was me yesterday at nearby Anglesey Abbey.  Although not as sunny as the day before it was spring-like.

We have a friend staying and we went here after having lunch in a nearby pub.

10m FT8 RX

Despite very poor solar conditions, the last 2 evenings has seen 10m FT8 spots (lots) from South America.

So far today, 7 unique stations spotted in 3 EU countries.

Solar conditions are similar, so let's see this evening!

UPDATE 1330z:  Still 7 uniques in 3 countries, all EU.

Liverpool Quiz Book - NOT amateur radio

A good friend of ours is a blue badge guide to Liverpool. These blue badge guides are trained guides who take people around this vibrant UK city.  He often takes visitors from cruise ships. He has recently had a quiz book published. You can buy this at various places in and around Liverpool, or from Amazon.

Work "do" - NOT amateur radio

This picture was taken by a friend many years ago. I have no idea what the occasion was. It looks like all males and I am enjoying the wine. Probably about 30 years ago? It was something to do with work, but I have no memories of it. No, that is not a result of the wine!

Sunspots - Saturday April 6th 2018

Solar flux is 66 today and the sunspot number 0. A=9 and K=1.

10m FT8 today (Friday)

Once again I am monitoring 10m FT8 RX today. So far, only 2 stations spotted - a G and CT1FHW (1681km). I am staying on late in case the band opens again to South America as it did late yesterday. Conditions seem quite similar to yesterday and no better.

UPDATE 2125z:  South America again this evening on 10m FT8.

Yesterday - NOT amateur radio

This is a collage of yesterday. We had something quite rare - sunshine!

6m in the Es season

We are rapidly approaching the Es season, bringing alive 10m and 6m and to a lesser extent 4m and 2m with DX up to about 2000km.

Frequently the distances are much further, bringing into range some true exotic DX on 6m.

This year we also have FT8, which is already proving its value as a DX mode. I shall probably be monitoring 6m FT8 RX this season. I suspect 6m will be "open" far more often than we expect!

10m FT8 yesterday

Quite late (after 9pm UK clock time) 10m FT8 opened to South America with lots of stations spotted. I was surprised, as conditions on paper were dire.

10m often opens N-S and FT8 finds the briefest openings now.

Sunspots - Friday April 6th 2018

Solar flux is 66 (very low) today and the sunspot number 0. A=9 and K=1.

Grass cutting - NOT amateur radio

It has been too wet and cold to cut the grass, but today felt like spring. We have a blue sky and it actually felt like spring for the first time! I managed to cut the front and back lawns this afternoon and even had a beer in the garden afterwards in my shirt sleeves.

Spring? - NOT amateur radio

Today our sky is blue. What a change.  We have had a long winter and, until today, no real spring: winter seems to have gone on for ever. My son planted some daffodils back in the autumn. These (see photo) are now well out next to our shed.

Amateur radio from the Moon?

Southgate News carried a report about 2 Chinese satellites due for lunar orbits in June. These will transmit amateur radio data on 70cms and 13cms.

More OFCOM crappery

You will be amazed to hear from OFCOM that the first stage of their microwave spectrum auction has been completed. I guess this keeps the children off the streets and reporting this beats doing real work (for which a knowledge of RF is needed).

Sadly, all that seems to matter these days is money: everything else seems not to matter.

See http://ofcom.cmail19.com/t/ViewEmail/i/D93ACA184E8C41FF2540EF23F30FEDED/59D1BD3EA2F08127C67FD2F38AC4859C

10m FT8

Despite the poor prospects for 10m, I am on 10m FT8 RX today, ever hopeful. As yet, nothing spotted.

UPDATE 1256z:  Just G4HZW (210km) and G4CJC (74km) spotted so far on 10m FT8 RX. I suspect these come in by tropo.  In flat conditions I could usually work quite distant Gs  with 10W SSB on 10m. With FT8, both these stations are within range.

UPDATE 1506z: Just 3 Gs spotted on 10m FT8 RX today. Not that surprising.

Sunspots - Thursday April 5th 2018

Solar flux remains at 67 with the sunspot number still zero. A=5 and K=2. Poor!

15m QRP

Way back in 1984 I designed and built the Pipit 15m 800mW CW transceiver. For months it was the only rig I used. Some good DX was worked. It was written up in GQRP SPRAT in the days before PCs! Years later the box was used for something else. Taking it apart is now regrettable.

See https://sites.google.com/site/g3xbmqrp3/hf/15m_pipit

Virgin Media - NOT amateur radio

A friend of mine recommended the new V6 TIVO box. So, I ordered one which arrived today with a new hub, all free.

Installing it was easy, but there is a fault: every few seconds the signal on the TV seems to cut out. I never had this problem on the old box. Yes, I reset the hub and the V6 TIVO, but the issue remains.

Internet broadband seems faster and seems faultless. VM is sending out an engineer on Friday morning. Let's hope they fix it as VM is unusable on TV currently.

Keen photographer - NOT amateur radio

Our son is a keen photographer. This is him in our garden on March 26th. The sun must have made a brief appearance! He came up for a few days with his family.

2m FT8 RX

This is the mode I have used since breakfast.

So far (at 0912z) 6 unique stations in 4 countries with best DX PD0HIM (452km).

UPDATE 0948z: Now  8 uniques in 5 countries with best DX GM4JJJ (489km).

UPDATE 1327z: Now 21 uniques in 6 countries spotted today on 2m FT8 RX.

UPDATE 1920z: Now 37 uniques in 8 countries today on 2m FT8 RX. DK1VC (503km) is the best DX.
