630m QRP WSPR (Thursday)
My 10mW ERP WSPR from the earth-electrode "antenna" in the ground is turned on. So far, 8 stations have spotted me.
UPDATE 2018z: One of the advantages of WSPR is it will decode whether the signal is strong or weak as long as the S/N ratio is good enough. With a "decent " antenna and ground system, the S/N may be better, but a weaker signal will decode as long as the S/N is sufficient. 10 stations have spotted me so far this evening.
UPDATE 2145z: Spotted by 11 stations this evening.
Propagation today
The MUF in some parts of the world is high. It "feels" as if we are at the start of the long decline to sunspot minimum, although there is sometimes a second peak.

Cambridge Radio Club (CDARC) talk
About a year ago, I gave a talk at CDARC. Because of my poor voice these days actually I produced the slides and someone else did the talking! Ovearll, it was quite successful.
Good and evil - NOT amateur radio
When I was younger I believed everyone was basically good and the evil they had was a result of upbringing or genes. These days I am not so sure. That evil exists is not in doubt. In this world that we share there are plenty of signs.
It is my view that we are all capable of evil. That is what frightens me. We all have to do our best to replace evil with good.
SETI (the search for intelligent live in the universe) - NOT amateur radio
Now AI has been brought in to help data processing. According to the BBC there are potentially 10-50 billion places where intelligent life could exist just in this galaxy alone.
There are so many variables like where do you look in the electromagnetic spectrum. Indeed, is this the best place to look?
If we found signs of intelligent life, it could have profound effects on this small blue dot.
10m 500uW (0.5mW) WSPR (Thursday)
With the sunspot number being so low compared with a few months ago, I think it is very unlikely I shall be spotted today with this tiny power. As a sucker for punishment though my 10m WSPR beacon is again on without the PA.
UPDATE 1710z: No spots all day. Am I surprised? No.
2200m transverter
Last night I gave the latest version of Google's AI tool (now called Gemini) a try. I tried various family names, without being impressed. Basically, compared with ChatGPT4, it was hopeless. They have a long way to go to catch up in my view.
I then tried G3XBM and it came up with a French site that had a copy of my 137kHz transverter from 2011. I think it was a prototype (no RX preamp) and I cannot even remember producing the circuit. The schematic is the best I have. It shows the loop antenna that I used. Zooming in on the schematic makes it a bit clearer. As I recall, the furthermost I got was the Netherlands on QRSS3.
