Scones - NOT amateur radio

Four years ago I first made these savoury scones. I must make some more. 

Intelligent life "out there" - NOT amateur radio

As far as I am aware the SETI project has been looking for intelligent life in the universe for almost 60 years. As far as I know, nothing has been detected. Maybe our methods are flawed?

What seems probable, but not certain, is that "out there" somewhere intelligent life does exist. Even with pessimistic estimates there are 10s of intelligent civilisations in our galaxy. There are trillions of galaxies in the observable universe, so the probability of intelligent life existing somewhere goes up. They may be so far away that we cannot interact with them, but with time we may detect some of them.

All this makes me puzzled. All religions seem too small and too human-centric.  Life is a total mystery.

Sunspots - Monday October 11th 2021

 Solar flux is 85 and the SSN 38. A=9 and K=3.

Simple radio project

My original post was banned by the censors as it violated blogger guidelines, probably as the algorithm saw certain words.  Talk about nanny state!! In the gaps, insert letters!

With my own ch***n, I totally failed to get them interested in amateur radio! In 2 weeks time my gran###n is here.  His d*d has asked me to work with him on a radio project.

I have ordered a TA-7642 (ZN414) TRF chip from GQRP club sales, but realise I shall also need a small slab ferrite rod, a high impedance crystal earpiece and a 1.5V battery holder. My building skills are really poor compared with before my stroke: what would have been really easy is now hard.

If I cannot find these parts, I shall have to build an LED signaller instead.

It would be good to see another novice operator. Oh look, there's another flying pig.  😉 

10m FT8 RX

At about 1350z, I QSYed to 10m FT8 RX as 6m seemed so dire. So far, 7 stations have been spotted with the furthermost CO8RH (7231km) in Cuba. 

10m seems to be reliably opening to the USA and Canada again via F2. 

UPDATE 1526z: So far this afternoon, 83 stations have been spotted on 10m FT8 RX, mostly in the USA.

UPDATE 2003z: 368 stations spotted this afternoon on 10m FT8 RX. 10m F2 propagation is definitely back in a big way! QRT.

King's College Chapel, Cambridge, robes - NOT amateur radio

 

The photo shows the rear of King's. These are the choir robes I think.

Dartmouth Devon - NOT amateur radio

The photo shows Dartmouth a few years ago. 

6m FT8 QRP (Sunday)

Just before 1100z, I turned on 6m FT8. After a short time (minutes) on 2.5W TX, I am RX only using the V2000 vertical omni antenna. So far, no spots on RX, but spotted by G0PQO (50km) on TX. 

It would be a pleasant surprise to spot anybody on 6m today. Although Es does occur, it is far less common at this time of year.

UPDATE 1335z:  Just 2 Gs spotted today on 6m FT8 RX. As 6m seems so poor, I shall probably QSY, probably to 10m FT8 RX.

2m FT8 (Sunday)

After a brief few minutes with 2.5W TX to the big-wheel (7 stations spotted me) I am RX only now. On RX 14 stations spotted in 5 countries with the furthermost MI0IHH (473km). Judging by the strength, I think this one in N.Ireland was aircraft scatter.

UPDATE 1038z: 28 stations in 7 countries spotted on 2m FT8 RX today. It never fails.

10m WSPR QRP (Sunday)

At about 0920z, my 500mW W5OLF 10m WSPR beacon was turned on. So far, no spots.

UPDATE 1040z:   So far spots from 3 unique stations with the furthermost by TA4/G8CSU (3010km).

Bolt Tail - NOT amateur radio

 

I can trace my family history back to the mid 1500s in this Devon village (Hope) near here. This is Bolt Tail. It is possible my ancestors manned this Iron Age fort built here thousands of years ago. 

Sunspots - Sunday October 10th 2021

Solar flux is 81 and the SSN 14.  A=5 and K=2.

2m FT8 QRP (Saturday)

At about 2030z, I went on 2m QRP FT8 with 2.5W and the big-wheel omni antenna. I was on TX for about 5 minutes and was spotted by 11 stations. Since then I been RX only and spotted 14 stations.

10m WSPR TX

For the first time in many months, I am on WSPR TX with 500mW using my W5OLF stand-alone beacon. The beacon was turned on at 1300z.  

As 10m is moving to a decent F2 daytime DX band, it will be interesting to see where this beacon is spotted. 

I think more people are now on FT8 than WSPR, but I was surprised by how much WSPR there still was on 10m back in the Es season.

I have been spotted by local G4KPX (14km) so I know it is working.

UPDATE 1318z: 4 spots already with furthermost FY5KE (7110km).

UPDATE 1417z: Someone pointed out an error on the WISPY TX schematic. Where it shows 9t, it should be 22t with the oscillator collector resonating at 28MHz, the second harmonic of the crystal. 35 spots of me so far today on 10m WSPR TX.

UPDATE 1806z:  EA8BFK (2880km) has been spotting me as strongly as an incredible +11dB S/N. This implies he would spot me at uW levels.

UPDATE 1919z:   4 unique stations have spotted me today. The furthermost is PY1EME (9453km).

Inside King's - NOT amateur radio

King's College Chapel in Cambridge is world famous. It dates back centuries.

This is a view inside with the famous Ruben's painting over the altar.

The photo was taken from under the organ.

Because of the Covid-19 pandemic, we practically had the place to ourselves.

As locals, we can get free entry. 

Oscar 100 SSB activity

It gets worse!  

As you know I periodically have a peek at activity levels on this geosynchronous satellite. The last time I checked was a Saturday morning in Europe, which I would have expected to be one of the busiest times. Sadly, there was hardly anybody active! I saw just 2 signals! 

See https://eshail.batc.org.uk/nb/ .

Salcombe rainbow - NOT amateur radio

This was where I spent my childhood. The rainbow was last Sunday. This was the view from my school window - less the rainbow! 

Sunspots - Saturday October 9th 2021

 Solar flux is 92 and the SSN 13. A=4 and K=2. 

10m FT8 RX (Saturday)

 At 0745z, I switched on my 10m FT8 RX. No spots yet.

UPDATE 0820z: Just 1 spot on RX of OZ1RH (824km). Could be Es or aircraft.

UPDATE 0941z: 32 stations spotted on 10m FT8 RX in 3 continents with furthermost ZS6AF (9141km). Most propagation on 10m seems to be F2 now.

UPDATE 1206z:  66 stations spotted on 10m FT8 RX today.

6m AM Sixbox

If you are after ideas for a cross town natter box, you may get some ideas from my Sixbox. This is not a DX transceiver, but is useful for chatting locally with friends. If you are making several as a winter project, you may want to do a PCB, although I did not bother.

King's, Cambridge - NOT amateur radio

This is a photo of one of the most famous places in the world. As locals, we get free entry. 

Tree - NOT amateur radio

For about 5 years now we have been following this tree at nearby Anglesey Abbey through the seasons. As there is a severe fuel shortage (none in 5 garages yesterday) in this part of the UK, we feared we might miss it this autumn, but our son took us yesterday. It was stunning.

10m FT8 RX (Friday)

Since 0755z, I have been on 10m FT8 RX. So far (at 0825z) no spots.

UPDATE 1524z:  So far today, 213 stations spotted on 10m FT8 RX.

I failed

The photo shows one of our grandchildren some years ago. It shows him in my workshop some time ago. He is now a teenager and is not at all interested in amateur radio. 

Sunspots - Friday October 8th 2021

Solar flux is 86 and the SSN 13.  A=5 and K=1.

Whatever next!! ? - NOT amateur radio

"Evolving the AdSense ecosystem"

What the heck does this mean? I received this in an email today. Why can't they just say what they mean in plain English instead of this meaningless drivel?

OFCOM and fees for 412MHz spectrum

 OFCOM has announced the future fees for spectrum at 412MHz. See the OFCOM website for details.

Phlatlights

In 2012, I bought several of these from the USA. My intention was to use these very powerful LEDs in my experiments with 481THz light communications over the horizon having had great success with QRSS over the horizon with far less powerful LEDs. 

Then I had my stroke and I was just too wobbly for field work. They are still in the shack drawer! It would be great to use these as I am sure much further non line-of-sight would be possible.

10m FT8 RX

At about 0810z I turned on 10m FT8 RX. No spots yet.

UPDATE 1044z:   It helps if you connect the antenna!! For the first 2 hours I had forgotten to connect the antenna! I was surprised to get no spots in the first few hours. I then connected the antenna and got 5 spots with the furthermost A92AA (5069km).

UPDATE 1132z: 16 stations spotted on 10m FT8 RX with the furthermost  PY2XB (9599km) in Sao Paulo, Brazil.

UPDATE 1318z:   36 stations spotted today on 10m FT8 RX.

UPDATE 1905z: 124 stations spotted today on 10m FT8 RX. 10m is really getting back in its stride as a great DX band.

137kHz transverter

 

This photo, taken about 10 years ago, shows my 137kHz TX transverter. I still have it...... somewhere.

See  https://sites.google.com/view/g3xbm4/home/hf-mf-and-lf/homebrew/2200m-137khz-transverter .

Dalham - NOT amateur radio

This was the nearby village of Dalham some years ago. It is filled with thatched cottages. It is located not far from Newmarket, the home of horseracing.

Yesterday on 10m FT8 RX

10m has changed from a quiet marginal band to a great daytime DX band. Yesterday 248 stations spotted on RX from all over the world. 

Sunspots - NOT amateur radio

 Solar flux is 85 and the SSN 22.  A=8 and K=1.

Soon be winter, brrrr - NOT amateur radio

A few days ago, I cut our front lawn. The nights are already getting darker sooner. 

We have already switched to "winter mode". 

8m NoV submitted to OFCOM

My online application for a time and power limited access to the 8m band is with OFCOM and the RSGB. OFCOM has acknowledged receipt. No doubt it will take months to process. I hope it is successful.

I note that the OFCOM NoV application form has a tickbox to say the RSGB approves. I guess without this they immediately reject it.

Burwell 2015 - NOT amateur radio

 

This was the sky over our village in 2015. It was a FaceBook memory yesterday. 

I was commenting yesterday that we have had very few swallows (birds) this summer, but swifts seem as plentiful. It would appear swallows are more localised. At this rate we could see no swallows within a few years.

10m FT8 RX (Wednesday)

At about 0745z, I turned on 10m FT8 RX. So far,  no spots.

UPDATE 1222z:  59 spots on RX so far with the furthermost ZS6RHL (9089km). Most propagation on 10m now appears to be by F2.

Mappa Mundi - NOT amateur radio

 

Yesterday, my brother went to see this in Hereford Cathedral. It is one of the oldest maps in the world. 

Sunspots - Wednesday October 6th 2021

 Solar flux is 82 and the SSN 27. A=5 and K=2.

2m activity contest (UKAC)

 This evening, I went on 2m SSB with 10W and the big-wheel omni antenna. I was on for about 30 minutes. GD was heard, but not worked. I stopped early because of my poor voice after working 6 stations.

10m FT8 RX

 

Late this afternoon and this evening, I have been on 10m FT8 RX. 34 stations spotted today (see map).

Coasters and placemats - NOT amateur radio

 

We recently bought some placemats and coasters as shown in the photo.

OFCOM updates

 As usual, OFCOM has updated its "Communications Monthly" with the latest statistics it holds.  See the OFCOM website for details.

Sunspots - Tuesday October 5th 2021

 Solar flux is 84 and the SSN 29.  A=6 and K=3.

More Corpus Christi College, Cambridge - NOT amateur radio

 

A few weeks ago I showed one of the quads at Corpus Christi College. This is another one.  I think I mentioned last time that this college was founded in 1352.

See https://www.corpus.cam.ac.uk/ .

2m activity contest (UKAC) Tuesday evening

As I was away, I missed the last one, but hope to be on Tuesday evening. Usually I run 2.5W to my omni big-wheel antenna for about an hour.  It is organised by the RSGB. Friendly and fun. Not like an HF contest!

See https://www.rsgbcc.org/cgi-bin/contest_rules.pl?year=2021&contest=2mukac .

10m FT8 RX

 Since about 1315z, I have been on 10m FT8 RX using the simple 10FT8R receiver.

So far, just 1 station spotted at 1322z on PSKreporter maps - a local G0VQH (13km).

UPDATE 1342z: 5 stations spotted so far on 10m FT8 RX with the furthermost EA8AXT (2996km).

UPDATE 1712z: 40 stations spotted today with furthermost 4X4OQ (3615km).

UPDATE 2126z:  QRT.

Corruption - NOT amateur radio

Some secret papers have just been leaked. They seem to confirm that many politicians the world over are corrupt. All along, I have thought how few are in politics for the greater good. Whatever a politician says, do not believe it! This seems to be the message. Sad. There is some explaining to be done.

See https://www.bbc.co.uk/news/uk-politics-58783460 .

Museum cafe duty (Sunday afternoon) - NOT amateur radio

The photo shows me on duty in our local museum cafe yesterday with my grandson before he returned home. My wife and I share duties. The museum is just across the road from us.

See https://burwellmuseum.org.uk/ .

Yesterday on 10m FT8 RX

In all, 89 stations were spotted on 10m FT8 RX with the 10FT8R yesterday. 10m is definitely moving more towards an F2 DX band again.

See https://sites.google.com/view/g3xbm4/home/hf-mf-and-lf/homebrew/10ft8r-rx .
