Chromebook buglet? - NOT amateur radio

Having owned my little Chromebook for about 5 months now, I am so pleased with it. It boots up almost instantly, the battery lasts at least all day, and does everything I want. It beats Windows hands down.

I am aware of just one buglet. When I get a Facebook message I can see the Chrome page headings, but the page remains blank until I reboot the PC. Luckily this is very very quick. I have no idea why this happens.

Trump - NOT amateur radio

Yet again, President Trump has shared his great wisdom. Aren't we lucky to have such a wise and intelligent man at the head of the free world?

Maybe he is better at golf? Maybe not.

You, the good people of the USA elected him!

I still find it puzzling that it seems you have to be an old (preferably very old) millionare to stand a chance of being elected as USA president. Surely you can find someone younger who truly represents the USA on the world stage? Everyone from the USA I have ever met has been kind and generous.

UPDATE 1757z: I have just seen his recent press conference.  Enough said.

10m FT8

As 10m Es was pretty good yesterday, I have decided to try 10m FT8 again today with my 2.5W and uessthe tiny indoor loop antenna. The rig was turned on at about 0834z.

UPDATE 1417z : 2 spots of my 2.5W so far with the more interesting being by MW0ZZK (334km) in NW Wales. Not sure what propagation this was - too near for Es and a long way for tropo. Aircraft? 2 Gs spotted so far on RX plus 1 in Poland.

UPDATE 1435z:  Now CT2EHX (1815km) spotted.

UPDATE 1535z: Now 7 stations spotted here today on 10m FT8 RX. It almost feels like someone has turned on the Es switch. I guess more people are now monitoring.

Stations copied here
today on 10m FT8 RX
UPDATE 1743z: 4 stations have spotted my 2.5W today although IQ3NX (1129km) is reporting the wrong band!! On 10m FT8 RX, 16 stations spotted so far today.

Climbing pound? - NOT amateur radio

Since the coronavirus hit the world, everything feels different.

It almost feels surreal and that somehow life will never, ever, be quite the same again. Right now things seem dreadful. In time, things will get better, but it will take time and hard work.

Since the crisis started the UK Pound fell heavily against the Euro. In recent weeks it has regained much of those losses. Maybe the world sees the Euro under threat as the coronavirus debt has to be paid, probably by the richer north.   With the UK out of the EU, perhaps the UK will be master of its own destiny? At the moment it is still climbing.

The world has never been in this situation before and we are all searching for a way. The hope is in a vaccine (some way off) or drug treatments (possibly sooner).

UPDATE 0840z: Still climbing.

Gecophone 1920s crystal set

When I retired in 2008, I was given a 1920s crystal set as a leaving present.

It was in good condition and was a total surprise.

DST100 receiver

Way back in the early 1960s, my very first communications receiver was a war surplus DST100 bought for £7 from a local garage. It was huge and very heavy! It was also very deaf, but Roger Thorn G3CHN managed to breath new life in it and it lasted me for many years.  He probably put in new valves.

It needed 2 people to lift it and was a tank radio made by Murphy. It was certainly built like a tank and could probably have survived a direct hit!

To think now we can get an SDR in a USB stick with better performance and a much wider frequency range.

Early voice recordings - NOT amateur radio

It is often thought that the earliest voice recording was by Thomas Edison, but there is evidence that the earliest recording was in fact made in France in 1860. You can hear this at http://graphics8.nytimes.com/audiosrc/arts/1860v2.mp3

Oil producers agree 10% cut in output? - NOT amateur radio

Although I have yet to see this confirmed, it looks like the biggest oil exporters including Saudi Arabia and Russia have agreed a 10% cut in oil output in the light of a heavy fall in demand.

I think this should help to stem the heavy falls in recent weeks. Whether or not oil prices recover remains to be seen.

Codar AT5 transmitter

Way back in the late 1960s, I had a G8 call and used to operate the station of the late G4PJ under supervision. 

Bill had a Codar AT5 160/80m AM/CW 12W TX which put out a good signal. I recall very well working a station about 70 miles away on 80m AM one afternoon.

Although I owned the companion RX (the T28) , I never owned an AT5. I wanted one! The photo shows the AT5 transmitter. We have come a long way since those days.
