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.

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.

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.

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.
