Grooming gang - NOT amateur radio

"During the three trials, jurors heard how the men - who are all British Asians of mainly Pakistani heritage - preyed on young, vulnerable girls, one of whom was described as having the mental age of a seven-year-old." From the BBC report.

I am most definitely not a racist. Many of my friends come from backgrounds other than white British. What really puzzles me is why every member of this gang is Asian. Is it something in their culture which makes them more likely to act in this way? It is inexcusable. Rather than pay for them in jail, send them back to Pakistan on the first plane. If they cannot follow our way of life, they deserve no part in it.

Coax cable

It is many years since I last bought coax (2012?), so I am a bit out of touch on prices, types and sizes. Come to think of it, I must have bought some low-loss coax when David G0LRD installed my 2m big-wheel, but I cannot recall where I got this from!

Every weekend, MLS has some special weekend deals and this week it includes coax and coax tools.

JS8Call

This is a development of FT8 to allow longer messages. It is not something I have tried. To me, FT8 is enough, but others may be interested. I believe it is at release 0.75.

WSJT-X

There is a lot of free software at this site for digital communication. WSJT-X is still in beta release with the full Rev 2.0 version due in December. If you want to try some digital modes, take a look.

Living "in the moment" - NOT amateur radio

A lot of us spend a lot of our time worrying about tomorrow. Often, what we most fear does not happen!

There is a technique which may help. This has rapidly turned into a word for our time, but there is good science behind it. Mindfulness.

Sometimes we have to think about tomorrow, but perhaps we spend too much of our time needlessly worrying, when we should concentrate on enjoying the good things around us now.

More signs of autumn - NOT amateur radio

This photo was taken by my son in Kent a few days ago. More signs of autumn.

10m FT8 again

Rather than 10m WSPR, I have again opted for 10m FT8 today. An earlier CQ was spotted by no-one and, as yet, no-one spotted! Not a great start I have to admit. 😕

Nonetheless, I shall stick with the band and put out the odd QRP CQ on 10m FT8 now and again. In the past few days, the best DX came through in the early evening.

UPDATE 1317z: Apart from a couple of German stations spotted this morning, all very quiet on 10m FT8 RX.

UPDATE 1410z: Surprise, surprise! A recent QRP CQ (2.5W) on 10m FT8 was spotted by GW4BVE (237km). No QSOs though. Tropo or aircraft?

UPDATE 1652z: G4CJC (74km) in north London spotted on 10m FT8 RX. No DX. A CQ earlier (2.5W) got no spots! Will we see South Americans tonight?

UPDATE 1949z: Only a single South American this evening here on 10m FT8 RX - PU5FGR (10026km). I am not sure if this was just a poor night or the end of the propagation for the season. At 2000z I shall go QRT on 10m as I think that is it for today. Just 6 stations, 4 countries, 3 continents today on 10m FT8 RX.  I'll try  again tomorrow.

Coming autumn - NOT amateur radio

Spiders web on the window earlier
It is definitely getting colder here. In the garden it now looks like autumn with leaves really falling and dew on the grass.  In a few weeks most trees will be bare.

The seasons are great: each has something special: the long warm summer evenings and snuggling in front of the fire on a cold winter evening.

Sunspots - Friday October 19th 2018

Solar flux is 69 today and the sunspot number has returned to zero. A=2 and K=0.

10m Simple Sideband

My health has not been good for over 5 years, so work on this project stopped sadly.

The ideas were good ones and I am sure there is mileage for someone to progress these. What I really want is for someone to take this on and produce a really simple kit including a PCB and all the parts.

Every summer, such a rig would work right across Europe on 10m. In a few years real DX should be possible with modest wire antennas.

It would make a nice club project. First of all, someone needs to finish the development!

Now 10m FT8

Every time I have looked recently, 10m FT8 has been "open" to South America early evenings. So, I have QSYed from 2m FT8 to 10m FT8. We'll see. My antenna is not too brilliant either, so I'm sure others will do much better.

UPDATE 1615z: Just a spot of G4DJB (128km) so far on 10m FT8 RX.

UPDATE 1750z: Several South Americans and the Falkland Is stations now coming through. 12 stations in 7 countries in 3 continents spotted today on 10m FT8 RX.

UPDATE 2000z: Now QRT on all bands. Yet again, loads of South Americans (14 in all) spotted on 10m FT8 RX today.

Local bakers - NOT amateur radio

Yesterday I showed a photo outside our local bakery that looked like a dead rat, but which was actually ivy. Should have gone to Specsavers!

This baker makes excellent soft rolls - far better than those at nearby supermarkets. They do a good trade in filled rolls to passing workmen.

Grumpy old man! - NOT amateur radio

Yes, don't tell me as I already know - I have definitely become a grumpy old man!

When I was waiting for my Park and Ride bus earlier, it seemed that everyone under 25 was on their smart phone.

Disappointment on 472kHz WSPR

Overnight I was on 472kHz WSPR, but only a couple of stations spotted my 10mW ERP this time. On RX, I again spotted Italy and Norway. Perhaps the rising noise floor is clobbering my little signal? Or is the novelty wearing off and there are fewer stations? Often according to WSPRnet there are very few UK stations on TX on 472kHz.

RadCom article

Much to my amazement, my short article on FT8 has been published in November RadCom. I was hoping to see it in a few months, but this took me totally by surprise!

Sunspots - Thursday October 18th 2018

Solar flux is 69 today and SSN=11. A=3 and K=1.

2m FT8

It never seems to fail! Yet again a CQ (2.5W to the big-wheel omni) was copied by 2 Cornish stations on 2m FT8 at around 460km.

At the moment on 2m FT8 RX 4 stations spotted in 4 countries with best DX DL2PK (448km).

UPDATE 1325z: 27 stations in 7 countries so far on 2m FT8 RX today. Best DX is DJ6GK (607km).

UPDATE 1620z: Another great day. Now QSYed to 10m FT8 RX.

QSY to MF WSPR

Until a little while ago, I had been out of the house. Now back, I have gone onto 472kHz WSPR (20% TX, 10mW ERP). All being well, I shall be on 472kHz until breakfast.

Return to 10m FT8

At about 1535z I went QRT on 2m and returned to 10m FT8. A brief CQ was called (2.5W) but no spots. So far no spots on RX.

UPDATE 1751z: 2 South Americans spotted so far on 10m FT8 RX. This never seems to fail.

UPDATE 2025z: In total 3 South Americans spotted on 10m FT8 RX. Is this conditions worsening?

HF and VHF FT8

Although not a great mode for chats, there is no doubt that FT8 has really taken off. DX that was once unimaginable is possible, even with QRP and small antennas.  I suspect many put their receivers on FT8, maybe endlessly call CQ, and leave it to see what comes through, looking later. Fewer people will just talk in the future, which is sad. There is even an automatic mode, so you can be gardening whilst your PC is having a QSO!

Certainly for me, real 2m DX is possible every day even with QRP.

The danger is people leave modes like FM, SSB and CW and move instead to FT8. Casual listeners will not "find" amateur radio as we did years ago.  How people "find" our hobby is important for the future.

One of my first experiences was accidentally hearing a local amateur on 160m AM. What are the chances of this today?

Dead rat? - NOT amateur radio

This was spotted outside our local bakers.

At first I thought it was a dead, shrivelled up, rat that someone had put there to say, "don't use this bakers".

On closer examination, I could see it was ivy!

BTW, the bakery makes excellent soft rolls!

BREXIT - NOT amateur radio

There is no doubt that Theresa May, the UK PM, must regret the alliance with the DUP in Northern Ireland as it is they who are effectively blocking a withdrawal agreement with the EU. The sticking point is the border with Eire. Neither the EU or UK wants the return of a hard border.

When she held a snap general election we all expected her Conservative government to win an outright majority. Instead, her position weakened and she depends on the DUP for a slim majority. Whatever your views are on BREXIT, this is not a recipe for strong government.

In my view, as no parties want a "no deal" divorce, we will either get more time or a fudge.

Short amateur callsigns

According to Southgate News, OFCOM is now issuing 2 letter callsigns for intermediate licences in the UK.

See http://southgatearc.org/news/2018/october/ofcom-now-issuing-short-2e0xx-intermediate-callsigns.htm#.W8bpO_ZFy00

2m FT8 for the day

It never fails! A CQ (2.5W to the big-wheel antenna) was copied by 3 stations including 2 in Cornwall. It seems Cornwall is nearly always within reach. I suspect this is my limit under "no lift" conditions on 2m FT8. With SSB or CW I'd struggle to get half as far!

On 2m FT8 RX, just 2 spots so far - a G in Kent and GM4FVM (428km).

I shall probably return to 10m FT8 later.

UPDATE 0936z: 9 stations spotted in 3 countries so far today on 2m FT8 RX.

UPDATE 1021z: 15 stations in 5 countries so far today on 2m FT8 RX.

UPDATE 1149z: Now 19 stations in 6 countries spotted today on 2m FT RX.

UPDATE 1530z: Now 35 stations in 7 countries spotted today on 2m FT8 RX.

Last night on 472kHz WSPR

Not as good as the previous night with less DX. My own 10mW ERP was spotted by 5 stations with best DX PA3ABK (306km) and I spotted 10 stations with best DX IW4DXW (1190km).
472kHz WSPR last night

Sunspots - Wednesday October 17th 2018

Solar flux is 69 today and the sunspot number 11.  A=5 and K=1.

16 Oct 2018

QSY to 472kHz WSPR (10mW ERP)

As 10m seems to have closed, I QSYed to 472kHz WSPR about 10 minutes ago. A couple of G spots of me (from the reports it looks like my transverter is still settling) and 1 DX spot on 472kHz WSPR RX: DC0DX (467km).

OFCOM technical advice

OFCOM has published technical advice on improving data access for rail passengers.

ICOM IC202 and IC202S

Probably few will recall these QRP portables. They were made by ICOM and followed in the footsteps of the Liner-2.

They had a very good VXO covering a decent part of the SSB band on 2m. Similar rigs were made for 70cm, and, I think, 6m, although I am unsure about this. I expect someone will tell me! (see below)

As you can tell, these had a very "military" look. Mine was mainly used at home, although some impressive 2m SSB DX was worked portable with just the whip antenna.

The quiet VXO made these rigs popular for IFs in EME rigs. I owned an IC202 and used it with a transverter on 10m too. Much DX was worked on QRP SSB.

UPDATE 1535z: Well, Bas (see comment) has pointed out the 6m version was the IC-502.

See https://sites.google.com/site/g3xbmqrp3/vuhf/ic202

Autumn - NOT amateur radio

On the whole, it is much warmer at this time in October than I can ever recall. Perhaps someone can tell President Trump that global warming is a reality.  At one time we had snows in winter and winters were very cold. Now snow is a rarity.

In the last few days we have had some winds and the tree in our front garden has lost most of its leaves and now looks autumnal.

Chinese lanterns - NOT amateur radio

At this time of the year the plants we call "Chinese Lanterns" are popular. There are some wild and some in garden centres as the ones in the photo.

Morals - NOT amateur radio

We live, mainly, in a post-religious world. OK there are many that still profess to be Christian, Muslim or whatever, but we live, mainly, as if heaven or hell do not exist and many care not a jot if when we die we just return to nothingness. The truth is no-one is really sure what happens after death, if anything. Even the most vocal atheist is not sure. There is still a lingering doubt.

All this brings me to morals.

In a, largely, post-religious world, what is our moral compass? In the past it was the fear of going to hell. These days what guides us? Generally, we are moral beings, even when we could lead a life of hedonistic excess. What is it that "programs" (most of) us to be moral beings with a sense of right and wrong?

Es'hail2 satellite

As mentioned before, this Qatari satellite is due to be put up later this year. It is expected to contain both a linear transponder and a TV transponder. Several people are gearing up for it. Unlike most amateur satellites this is in a fixed position. It uses a 2.4GHz uplink and a 10GHz downlink. So once the antennas are aimed, they can be fixed in position.

At the moment I am playing a waiting game. If it is successfully positioned and works as intended, I might try to install gear to receive it.

See https://www.eshailsat.qa/en/satellites/index/

10m FT8

Yet again, I am on 10m FT8 for the day. A brief CQ earlier was spotted by no-one at all and as yet no stations spotted here. So far, not a great start!

UPDATE 1002z: Still nothing spotted on 10m FT8 this morning!

UPDATE 1117z: So far today on 10m FT8 RX just a couple of Gs spotted with the best DX G0OYQ (177km). Disappointing so far today.

UPDATE 1250z: Best DX on 10m FT8 RX is EA7AAF (1647km).

UPDATE 1701: 4 Spanish stations and a German spotted on 10m FT8 today. No South Americans spotted yet today on 10m.

UPDATE 1757z: The first 2 South Americans on 10m FT8 RX came through here at 1715z. Best  DX is currently PY4XX (9252km). It seems that every time I look at 10m FT8 RX I spot South American DX. So far today, 4 South Americans (all in Brazil) spotted.

UPDATE 1945z: About to go QRT on the band. In all, 5 South Americans spotted on 10m FT8 RX.

Spotted in Norway on 472kHz WSPR

For the first time this autumn I was spotted in Norway last night by LA3EQ (769km). It was the best night this season.
472kHz spots of me last night

Sunspots - Tuesday October 16th 2018

Solar flux is 70 today and the SSN is 22. A=10 and K=3.

15 Oct 2018

Now on 472kHz WSPR

After another brilliant day on 28MHz FT8, I have now QSYed to 472kHz WSPR. So far, a couple of spots of my 10mW ERP, but no others yet spotted.

Antenna choices

Homebase-10 Antenna
When the leaves fall, I want to prune my silver birch tree, which is now far too tall. At the moment my Par end-fed covering 10m, 20m and 40m is held up by this tree. At present, I am considering options.

My main HF interest is 10m and one possibility is a rebuild of my Homebase-10 wire halo for 10m.  Via an ATU, the coax to this antenna should match on most HF bands tuned against ground.

Another possibility is my x80 vertical which is in good condition in the garage. This has a 9:1 unun in its base, so a decent match is presented to the rig on most HF bands. Verticals tend to be noisier than horizontals and the x80 can snap in winds.

I could re-erect my Par end-fed.  This is very low, especially for 20m and 40m.

At the moment, the favourite is the Homebase-10.

BREXIT and the Northern Ireland border - NOT amateur radio

A politician I am definitely not!

It seems the UK PM is stuck between a rock and a hard place over the only land border that will be between Eire (in the EU) and N. Ireland (shortly to be outside the EU).

The UK does not want a distinction between N. Ireland (Ulster) and the rest of the UK. The EU and UK want no hard border in Ireland.

The EU is playing hardball. In the end we could leave with no deal and the EU and the UK could both suffer. In the end I suspect a fudge is to be expected.
