Cave radio book
There is no way I would be climbing through narrow, dark, wet tunnels deep underground, but I have always been fascinated by underground communications at VLF and LF.
As radio waves get attenuated as they travel through water and rock and this attenuation is reduced as the frequency is lowered, cavers tend to use interesting techniques to communicate (and survey) with cavers.
A very interesting book by Mike Bedford G4AEE goes through all the techniques used by cavers.
Even for somebody like me who (would be too scared!) it make good Christmas reading. The book "Cave Radio" is available from the RSGB bookshop.

The freedoms of amateur radio
Many years ago I used to have many QSOs with stations across the world including the USA and the USSR.
As far as I am concerned we are all human beings with equal value whatever our beliefs, colour or politics. I enjoy exchanging greetings with an old work colleague who happens to live in Moscow and is a radio amateur.
One of the great things about our hobby is that it is such a great leveller.
Amazing AI of London in the 1600s
Just now, I watched an AI video of London in the 1600s. It was amazing and so very realistic. It was almost like really being there centuries ago.
In my view, this is an example of AI at it best. The "seed" was old engravings of various London scenes. Truly amazing.
