Sunspots - Saturday March 7th

 Solar flux is 143 and the SSN 75. A=7 and K=3.

630m WSPR RX (Friday)

My gear was turned on at about 1825z (coax to 2m big-wheel via ATU and a mains earth).

UPDATE 2010z:  So far, 5 stations have been spotted with the best OH6OHX (1736km).

UPDATE 2044z:  So far, 6 stations have been spotted with OH6OHX spotted 5 times.

Slowing?

These days I feel my age.   

Yesterday and today I cut the lawns for the first time this year. The first cut is often harder as the grass is longer, but I really felt tired afterwards. 

Also, as mentioned before, driving is stressful and I only drive locally and avoid driving at night. For many years I think my appreciation of speed has changed in that 45mph seems like 65mph to me! I am unclear if this is as a result of my 2013 stroke or just old age. 

Luckily, apart from my constant giddiness and poor voice most of the conditions of old age, like arthritis, have not caught up with me ...... yet!

The Trump Report

 This comes out (I think) every day from Times Radio. I watch it most days.

8m FT8 RX (Friday)

At 1106z, I QSYed to 8m FT8 RX.

UPDATE 1830z:   No spots all day. QRT now. I suspect this will be my last test on 8m until the Es season.

10m 2.5W FT8 (Friday)

My gear was turned on just after breakfast. I was on TX very briefly (7 spots) but I am mostly RX only. 

It is amazing that something this small works so well.

See https://shop.qrp-labs.com/qdxm

UPDATE 1056z:  395 stations spotted here on RX with the best H44MS in the Solomon Islands (14814km) in the Pacific Ocean.

Chromebooks

For many years I have used an Asus Chromebook. I am using one now. Mine has been brilliant. They use Chrome OS rather than Windows. This means that they do not run Windows programs. 

Despite that, they boot very fast and I have found nothing that I cannot do. I have created web-pages, presentations, letters and spreadsheets using the Google tools and surfing the web has been a dream using Chrome. 

I have never had a virus issue as virus checking is done in the background. Chromebooks are less expensive than Windows machines.

With all these things going for them, it would appear that John Lewis (a major UK retailer) has stopped selling Chromebooks. Why? Maybe they make less profit?

Out of choice my next PC would have been from John Lewis as they include a decent warranty on every PC. Ideally I would have bought another Chromebook.

Sunspots - Friday March 6th

 Solar flux is 146 and the SSN 73. A=4 and K=2.

Lode cottages

 

We went for a walk around this village near us after lunch. It has many fine cottages. Nice to see the sun.

WhatsApp "share location"

Yesterday I was in Cambridge for much of the day and turned on WhatsApp "share location" feature. I usually use the Apple "Find my iPhone" feature.

The battery drain with the WhatsApp location feature enabled was very high. In fact I was worried that the battery (which was 100% when I left home) would be flat. I shall not use this feature again.

Iran war

Everyone knows that Iran is treated as the pariah of the Middle East and that a more "western leaning" Iran  would be more supportive of President Trump and the Israeli government.

What I do not understand are the true motives and end game in this current conflict. President Trump was allegedly voted into office partly on the grounds that the USA would stop getting involved in "forever wars". Hmmm....

If he stops the threat from missiles, drones and nuclear weapons threatening Israel will he stop and walk away?  This war could end quickly or it could go on for years. In my personal view the USA could have done far more good peacefully in the world. As it is the Middle East (possibly elsewhere) has been turned into turmoil.

10m 2.5W FT8 (Thursday)

My gear was turned on just before breakfast. After a very brief TX period I returned to RX only.

UPDATE 2015z:  1696 stations have been spotted with the best FK8HA (16470km) in New Caledonia in the Pacific. 10m is as good now as I can ever remember it.  It is soon going to go downhill. Now QRT.

Sub 10kHz amateur DX in 2011

Back in 2011 I was very involved in amateur VLF below 10kHz.  

To be successful bandwidths of tiny fractions of a Hz are needed and integration periods of hours or even days.  As would be expected stability has to be perfect with many locking their signals to GPS or similar. 

Remember, amateurs have limited power and space for antennas!

DJ8WX was a regular signal back in 2011.

Sunspots - Thursday March 5th

 Solar flux is 141 and the SSN 71. A=7 and K=0.

10m WSPR Tuesday

When I am on a VHF band, I can use 10m 200mW with my Zachtek WSPR beacon. A point in case was yesterday when I switched to 10m WSPR TX late afternoon.

UK VLF record - 2011

In 2011, I received G3XIZ (45km) which was the most distant UK amateur I copied sub-10kHz. I cannot recall the bandwidth, but it would have been very narrow.

Bury-St-Edmunds

This is a market town in East Anglia, UK with some fine old buildings. Unlike Cambridge about 40km away it feels very East Anglian with locals who have families in these part for centuries. I really like it.

10m FT8 (Wednesday)

As I was in Cambridge much of the day I was on 10m FT8 RX only . 

UPDATE 1854z: So far, 1015 stations spotted. QRT soon.

Sunspots - Wednesday March 4th

 Solar flux is 144 and the SSN 64. A=16 and K=3.

Device memory

In the last 20 years or so, device memory has come a very long way.  256GB micro SD cards are now increasingly common, whereas just a few years ago this would have been amazing and unbelievable. It makes you wonder what will be the norm say in 2050 or 2100?

The human brain has an estimated capacity of 2.5 million GB, which is absolutely huge! Perhaps there will be a breakthrough allowing memories to have capacities approaching this? 

Will our grandchildren look back in amazement when we thought 1TB appeared huge.  I can remember when we thought 256k was huge!

10m 2.5W FT8 (Tuesday)

Another great start on 10m FT8. After a very brief period on TX (4 spots)  I went on RX only

UPDATE 1126z:   730 stations spotted with the best 3D2AG (16213km) in Fiji and Victoria, Australia which, to my surprise, is even further. I went on 2.5W FT8 TX again briefly with the best DX a spot of me on Reunion Is.

UPDATE 2136z: 2016 stations spotted here today. The best day yet? QRT now.

630m WSPR RX overnight

At last I managed to set up my 630m WSPR RX correctly! In all, 7 different stations were copied with the best OH6OHX (1736km) in Finland multiple times (see table). 

I used the coax to my 2m big-wheel antenna via a ferrite rod ATU and a mains earth.

End fed antennas

 A popular antenna is the end-fed if multi band coverage is needed. I use one for 17m-10m. At the end of the wire the impedance will be high so a transformer is needed to bring this to an impedance that can be directly connected to a PA or often via an auto ATU in the rig. There is a video about it on the DX Explorer YouTube channel. There is also a follow-up video.

Sunspots - Tuesday March 3rd

 Solar flux is 148 and the SSN 82. A=5 and K=2.

630m WSPR RX (Monday)

 This evening I am monitoring 630m WSPR. Hopefully this evening I have the settings right!

UPDATE 1900z:  3 spots by DC0DX (467km).  It works!

UPDATE 2136z:    Spotted 5 stations with the best LA8AV (1038km).

Sunday walk

Yesterday morning we had some sun so we went for a walk in a nearby village. There were still plenty of puddles.

Dalham near Newmarket, UK

 

This village is not far from us.

8m FT8 RX

 Most of the day I shall be monitoring 40.680 FT8 RX.

UPDATE 1730z:  I think I had my settings wrong on 8m FT8 RX!

Something wrong?

 Last night I tried monitoring 630m WSPR. Not a single station copied that suggests something was wrong.

UPDATE 0853z:  Yes, wrong audio source selected. I may try again tonight.

Sunspots - Monday March 2

 Solar flux is 147 and the SSN 85. A=8 and K=1.

6m 5W FT8 (Sunday)

For the first time in several weeks, I am on 6m FT8  with my vertical omni V2000 antenna and the IC-705.

UPDATE 1640z:   Just 3 English spots of me so far. No DX.

Stations spotting my 6m QRP FT8 today

UPDATE 1938z:   11 English stations have spotted my 6m QRP FT8. See map. QRT soon.

10m 200mW WSPR ((Sunday)

My Zachtek WSPR beacon was turned on at about 1430z.  

UPDATE 1518z:  18 stations have spotted me already with most in the east of the USA.  See table.

UPDATE 1540z:  28 stations have spotted me with the best PY2SDR (9616km) in Brazil.

UPDATE 1936z:  36 spots of my 200mW 10m WSPR with the best Reunion Is. in the Indian Ocean. QRT soon.

Sun? What's that?

We have had a dull and wet winter. It is now spring (according to the Met Office), so we decided to go for a walk in nearby Reach. 

For once, the sun was shining, although it has clouded over again!

10m 2.5W FT8 (Sunday)

 In a few minutes my gear will be on 10m 2.5W FT8.

Stations spotting my 2.5W 10m FT8 just now

UPDATE 1237z:  Plenty of spots of my 2.5W FT8 from North and South America.  Currently RX only.

In an art gallery window

 

This was in an art gallery window in Cambridge last week. I am informed it is the singer Prince, although I would not know!

Taking stock of the solar cycle

We are not clearly on the downward slope of the latest solar cycle. The downward slope is usually gentler than the rise from the minimum to the next maximum. 

Usually the higher HF bands get neglected as people move to lower bands. I am hoping with FT8 there will be more activity remaining on the higher bands. We'll see. Often CB is busy when 10m seems dead.

One useful resource is the site I often visit to see how things are progressing.

See https://www.solen.info/solar/

Another DXpedition

Just to show how much of a DXer I am not, I have to confess not having a clue where this is!  I am even unfamiliar with T31! If chasing DXCC is your thing, this may be of interest.

10m still in great shape

Stations received yesterday on
10m FT8  using the QDX-M

Yesterday I decided to stay on 10m FT8 RX all day using my tiny QDX-M which is smaller than a pack of cards. In all, 1851 stations were spotted from all around the world. We maybe on the downward side of solar maximum, but conditions remain superb.

QDX-M 10m

The map shows the stations received here yesterday on my QDX-M on 10m FT8  with just the low endfed wire.

Corruption in high office

Events of the last few weeks have confirmed to me that powerful billionaires command a lot of power and influence in the world. This is not in just one country. 

It would appear that powerful men and women are able to influence the workings of governments and the functioning of countries, being able to avoid justice and prosecution. 

There are dangerous people in high places.
