UPDATE 1500z: Spotted by 16 stations with the best V51RS (8481km). Amazing what 200mW WSPR to an indifferent, low, 10m antenna can do! See map from WSPR Rocks by Phil VK7JJ.
At the moment there is a lot of doubt about the claims of a small company revealing a solid state battery at CES that could revolutionise transport.
This one of many videos that expresses doubts. I guess we will have to wait and see.
It is true that companies have invested billions and are amazed if a small company really has "cracked it". Time will tell if this really is a breakthrough or just hype.
We are lucky to live right next door to Burwell windmill. It is fully restored. Here it is in full sail with the sails turning. The fantail ensures the main sails point into the wind.
In this video, the poster thinks President Trump is using his strategy outlined in his book "The Art of the Deal" to get a better deal with Denmark. It would appear most things the US president does is think about foreign policy as deals.
For the last few days I have been using the 200mW Zachtek WSPR TX. In the end I bought the original kit although it is being copied in China.
As far as I can tell, the Chinese copy does not have the low pass filters fitted so will have poor harmonic rejection. The Swedish version is far more expensive.
So far, with 200mW WSPR, it has reached 5 continents,
All timing is by GPS, which is built-in. Once programmed the unit needs no PC, so can run unattended. Mine comes covering 40m-6m. I also bought the all band RX, but I have not used this yet.
Is it only me, but I have come across not one person (absolutely no-one at all, really) outside of the USA that has a good word to say about the leaders of the USA currently. To many they appear brash and arrogant. This is sad as I have always found Americans kind and generous. Yet very many voted for Mr Trump. What he does in the USA i cannot comment on, but I can express my personal views as an outsider.
I am a great QRP fan. This video may inspire you. Without any amplification on RX I expect the RX is deaf, so best not call CQ, but answer other people's calls.
Events are moving very fast. This was written at 1012z on January 13th, so events may already have changed when you read this.
At the moment Donald Trump has threatened intervention, but not carried this out. It is clear that lots of Iranian people are deeply upset with, amongst other things, inflation that is making some foods totally too costly for many. If there was to be a revolution, there is no clear leader emerging. As I write we wait and see.
Cambridge is a very beautiful city, but like many it is gloomy in January! This is Rose Crescent in centre of the city. In the summer it would be thronged with tourists but it is much quieter in midwinter.
The "holy grail" of EV batteries is greater range, costs lower than lithium ion, no rare earths, fast charging times, long life and safe.
A Scandinavian company claimed at CES that they have made a breakthrough.
If correct, this really could be a real game changer. Imagine if EVs could be charged very fast and have great range and be no more expensive than a fossil fuelled car and only need an occasional charge. This could be the breakthrough like we saw with CRTs and digital cameras. It could also really help with climate change.
Look out for DONUT batteries.
I am sure all the major car manufacturers are working hard towards this. A tipping point IS coming.
As most appreciate, you never get something for nothing.
Very compact antennas tend to be very narrow band and inefficient. Nonetheless there are times such as SOTA these compromises are acceptable.
I remember working a station in Argentina on 10m SSB with just a few watts to a Miracle Whip some years ago from indoors! Compact antennas really do work. There are times when the loss of a few S points really don't matter.
The Gawant antenna is similar to the Miracle Whip. This one is homebrewed and I am not sure if it can be built ready-made.
