10m FT8

Well, I have been on 10m FT8 for about 10 minutes. At first I called CQ (2.5W). As yet, no spots either RX or TX. Now I am RX only on 10m FT8.

UPDATE 1315z:  Just a couple of G spots so far today. Best DX is G0NGL (222km). Poor!

UPDATE 1406z: PA8MC (404km) in Limburg spotted on 10m FT8. Aircraft reflection?

Anglesey Abbey - NOT amateur radio

We visit this National Trust property most months. Although it is in the top ten National Trust places in England and often busy, the grounds are so big you can often find yourself alone and far from crowds.

160m FT8 RX last night

In all, 40 North Americans and 1 Caribbean spotted here overnight on 160m FT8 RX as well as loads of Europeans again. Without doubt, the very best night this season! Best DX was K7RL (7605km) on the west of the USA. The earth-electrode "antenna" in the ground works fine.

Joule thief

If you have partially drained batteries, you may be interested in this idea. It can power LEDs from almost drained batteries, although with a bit of thought I am sure you can think of other uses.

This photo is on Wikipedia. The basic schematic is simple.

Reconnecting Korea - NOT amateur radio

Nearly my entire life Korea has been divided.  Years ago I went to South Korea for work, but never to the north.

I gather there are holidays in North Korea to include visits to potato farms and processing factories - not exactly my "cup of tea".  😉

Now there is a project to join north and south by rail and road. I really hope people divided by war can move freely and see long lost relatives.

North and South Korea are very different places these days. Seoul, the capital of South Korea, is a capitalist city, oozing wealth. The northern state capital, Pyongyang, is very communist and controlled.  Let the people of Korea decide how to move forward.

Sunspots - Thursday December 27th 2018

Solar flux is 68 and the SSN 0. A=3 and K=2.

Pye PF1 UHF handhelds

If you can find these, they can be converted to the 70cm amateur band, but they are hard to get hold of these days. TX power was 50mW. Perhaps they appear at rallies from time-to-time or on eBay?

My first project at work was converting these to 12.5kHz channel spacing. This was a task set by the late Mike Gotch, M0IMG. 

At the time I had no idea Mike was a keen amateur. Years before he had been a pirate and lost his licence I believe. In later years he was a keen 6m man. He retired early to care of his partner, who had cancer. Mike died as a result of the after-effects of a stroke.

The 12.5kHz version was never introduced commercially, but the exercise was a good one for me. The PF1, a product of the 1960s, transformed communications for the UK police. It was in 2 units, one for RX and one for TX. Even now, it still looks good.

160m FT8 RX

At 1510z I decided to QSY from 10m to 160m FT8 RX. As usual on 160m, I am using the earth-electrode "antenna" in the ground. It is now 1517z and nothing spotted yet. Once it gets dark, this will no doubt change!

UPDATE 1556z: Getting dark here now and already 14 stations in 10 countries spotted on 160m FT8 RX. Best DX spotted so far is RZ6LY (2943km).

UPDATE 1840z: Absolutely loads of Europeans spotted on 160m FT8 RX again. Results on this band have far exceeded my expectations with all over Europe and North America spotted every night.

Stations so far spotted here 

this evening on 160m FT8 RX

UPDATE 2006z: WU1ITU (4831km) was first spotted at 1958z. This is the earliest yet.

UPDATE 2310z: With 10 North Americans spotted already on 160m FT8 RX this evening, this could be the best night yet this season. I'll check again at breakfast time.

E-field probe RX antennas

These are RX only antennas, but they can be remarkably successful on VLF, LF and MF. Years ago I made my own, but these days building and erecting is much harder.

A while back I bought an EFP from Roelof PA0RDT, although I have not got it erected yet. Roelof gets good results with his, although they need careful sighting to avoid noise pickup. If you are interested in the lower bands RX only, these antennas may be your answer.

Birthday - NOT amateur radio

A couple of days before Christmas I turned 70. To be honest, it only seems 5 minutes since I was 18. This photo shows some of my cards.

Winter Es?

As is my usual pattern, I am monitoring 10m FT8 RX this morning. So far 3 stations spotted in 3 countries, all European. I am wondering if this is winter Es (sporadic-E). It could be aircraft reflection. If it is Es, maybe there will be more southern Europeans later?

UPDATE 1458z:  Now 8 stations spotted in 7 countries so far on 10m FT8 RX today.

UPDATE 1510z: As 10m is just average today, I shall probably QSY to 160m FT8 RX shortly.

Miracle antennas

It is some years since I last used my Miracle Whip, but they have their place. If you are after a compact antenna that is easy to tune, these may fit the bill, especially with a counterpoise and on the higher HF bands, when they may be just a few S points down on a "real" antenna. They are no miracle and can only ever be as good as a small whip brought to resonance.

Ba Humbug - NOT amateur radio

Christmas is meant to be a jolly and happy time.

At this moment my wife is playing a Christmas CD that is driving me insane!! Yes, I know it is a great time for children and getting together, but somehow things always seem more poignant at this time. Bad things always feel worse and I feel sorry for those in hidden pain (physical or mental) at this time.

To be honest, I am glad when it is all over and things get back to normal.

Overnight on 160m FT8 RX

Quite a decent night with 15 North American stations spotted on 160m FT8 RX, as well as loads of Europeans.

Sunspots - Wednesday December 26th 2018

Solar flux is 69 and the sunspot number 0. A=4 and K=0.

Return to 160m FT8 RX

It will soon get dark here, so a QSY to 160m FT8 RX is in order. This can be done in the background.  160m FT8 has been a real eye opener for me. DX is there to be had every day. My "antenna" seems to perform excellently and I cannot imagine doing any better with a dedicated topband antenna.

As you may recall, my "antenna" is just the earth-electrode in the ground. The baseline is about 10m, maybe less. I think this acts as a loop. On TX, I have received spots on 160m FT8 from Sweden over 1000km away when using 2.5W.

The QSY was done at 1540z.

UPDATE 1552z:  Just 2 spots so far - M0RTP (116km) and DL6ZBN (605km). Once it gets dark there will be plenty of DX .

UPDATE 1615z: DX from across Europe is appearing. Best DX is RV3F (2384km).

UPDATE 1830z: Somewhere over 50 stations spotted in 15 European countries so far on 160m FT8 RX.

UPDATE 2145z: WU1ITU (4831km) was first spotted at 2128z this evening.

Stations received on 160m 

FT8 RX this evening so far.

Ripe for renovation? - NOT amateur radio

On our pre-Christmas lunch walk earlier, we saw this old Volkswagen. I think they enjoy restoring old Volkswagens at this place.

Overnight on 160m FT8 RX

Not the best of nights. 5 North Americans and 1 South American spotted as well as lots of Europeans.

2m FT8

Whilst doing other things, I am monitoring 2m FT8 RX (saddo). Already 4 stations in 3 countries spotted with best DX being DF6PW (633km).

Happy Christmas - NOT amateur radio

Whatever your beliefs, or none, Christmas is a time for kindness and sharing. I hope you get some! From me, a very happy Christmas and may 2019 bring you success and good fortune.

Sunspots - Tuesday December 25th 2018 (Christmas Day)

Solar flux is 69 and the SSN 0.  A=4 and K=1.

Amateur VLF

Recently, there have been up to 4 stations active around 8.27kHz VLF. This is the excellent spectrogram at Paul Nicholson's station in Todmorden, UK. Such levels of activity are rare.

Names leaked too soon? - NOT amateur radio

Yet again, the gutter press has released the names of 2 people questioned by police in connection with the shutdown of Gatwick Airport by drone flights.

It is my firm belief that no names should be released at all until people are found guilty. Mud sticks and many an innocent person has had his/her life ruined by being named when they are innocent or not even charged.

See https://www.bbc.co.uk/news/uk-england-46675612 .

SAQ VLF transmission missed

Earlier today there was a CW transmission from SAQ on 17.2kHz. This uses an alternator TX and broadcasts heritage transmissions a few times a year. Years ago, I received a QSL card from SAQ for one of their transmissions. If, like me, you missed today's transmission you may like to look at this video of today's transmission.

See https://youtu.be/shqi43EV07c .

Now on topband

As 10m FT8 was flat today, I have QSYed to 160m FT8 RX with the earth-electrode "antenna". No spots yet, although I have only QSYed a few minutes ago and it is still light here.

UPDATE 1600z: Already 35 stations in 15 countries spotted on 160m FT8 with best DX RU4I (3202km).

UPDATE 1716z: The map shows the stations spotted on 160m FT8 RX so far today in the last few hours.

UPDATE 2034z: WU1ITU (4831km) was first copied on 160m FT8 RX at 2028z.

Iris - NOT amateur radio

This may have been on before, but it is a nice picture of a lovely flower seen at nearby Anglesey Abbey recently. Hope you enjoy it now, and possibly before!

Yes, it was on before last week!!

Sorry, but I really am losing it! My excuse is I post to so many places that I forget which - well that is my excuse. Truth is I cannot remember!

Ba Humbug - NOT amateur radio

Yes, I have officially become a grumpy old man!

My latest rant is about all the Christmas emails from companies and political parties. All they are really after is bigger profits or for you to sign up for their party. They have nothing to do with the spirit of Christmas. As soon as I get them they are deleted. Ba humbug.

10m FT8 RX

Most of the morning I have been on 10m FT8 RX. Only 2 stations spotted with best DX being DG5HR (719km).

UPDATE 1457z: One new spot from N.Ireland.

472kHz WSPR RX overnight

Last night, I stuck with 472kHz (630m) WSPR RX using the earth-electrode "antenna" in the ground. In all, 14 stations spotted with best DX EA7HPM (1725km) in southern Spain.

Stations spotted on 472kHz WSPR overnight

Sunspots - Monday December 24th 2018

Solar flux is 68 today and the SSN 0. A=2 and K=1.

MF WSPR RX

At about 1510z I QSYed to 472kHz WSPR RX. Already LA and PA spotted.

Best DX on 472kHz WSPR RX is LA2XPA (1310km).

10m FT8 RX

Most of the morning, I have been on 10m FT8 RX. So far, 10 stations in 6 countries spotted here. I am pretty sure some are coming in by winter Es. So far, all stations are European, with best DX OK1BRG (1104km).

I shall probably stay on 10m until dark then try 630m WSPR RX with the earth-electrode "antenna" in the ground.

UPDATE 1440z: Still just 10 spots. Looks like we had some Es this morning and it has now gone.

UPDATE  1510z: No further spots, so QSYed to 472kHz (630m).

137kHz

Last winter, I tried 137kHz WSPR and OPERA even though my FT817 is very deaf on LF.

In the past, when I was fit, I put my 137kHz beacon on QRSS3 and looked for the signal with a mag-mounted E-field probe on the car. Even though the ERP was low milliwatts at most, I got good copy the far side of Cambridge at about 24km.

At some point I should try 137kHz TX again. It was good fun. Maybe I should resurrect my 137kHz transverter. It is somewhere around.

Sunspots - Sunday December 23rd 2018

Solar flux is 70 and the SSN 0. A=3 and K=1.

160m FT8 RX overnight

Overnight 15 North Americans and 1 South American spotted on 160m FT8 RX with best DX N6VR (8354km) in Arizona, USA.

Antenna choices

In the very near future, I have to get a tree surgeon in to trim my silver birch tree. This is the support for the end of my 35W Par antenna for 10m, 20m and 40m. One possibility is the erection of my x80 vertical. This is in nearly new condition and has a 9:1 unun in the base to bring the SWR down to the sort of SWR that can be matched with most auto-ATUs. The drawback is it is quite "whippy" and blows around in the wind. It has never been used at this QTH.

Paddy Ashdown dead - NOT amateur radio

One of the heavyweights of UK politics has died aged 77. Paddy Ashdown was one of the few charismatic leaders we had. One of the problems we have is a lack of real leaders in waiting. Most in politics seem to be there for their own advancement rather than for the greater good.

Although many did not like his politics, I liked Tony Benn. He was an honest man.

What the entire western world needs badly is leaders who want high office for the greater good and not self advancement.

Food this afternoon - NOT amateur radio

The previous post mentioned the gathering we had this afternoon for a few friends. The photo shows some of the snacks. My savoury tartlets (cooked earlier today) proved very popular! Most had gone even though I made 24. I shall have to do more tomorrow. The fillings are onions, cheese, red peppers, mushrooms, tomato and a tiny bit of chutney. Some had ham too. The secret is to cook these first and then put more cheese on top before baking. My wife does the pastry the night before. I roll this out very thinly.

Pre-Christmas gathering - NOT amateur radio

As it is my birthday tomorrow and Christmas on Tuesday, we had a few more friends around including Richard G3TFX and his wife.

Last week we had some of the neighbours around.
