As a slight aside, but still to do with radio, I have a CB in my Land Rover (which I bought from Mr Broccoli, but that's another story). I'm in Germany so I should really apply for a license, but the most I hear is Polish chit chat "repeat please..." so. meh.
However, very occasionally I hear a ham broadcast from the UK. They must have bloody powerful transmitters.
Also, I usually leave it on channel 9 and sometimes on Sunday there's some pillock reading chapters from the bible in a yank accent so this ******** is blocking the emergency channel in Germany by reciting lengthy text in English. Rather poor radio procedure.
I used to have a 25W amp on my CB back in 1981/82 a friend of mine did something with my antennae using his professional SWR meter, copper wire, wire cutters and a soldering iron. If I sat on the top of the hill at Wroughton I could hear and chat to septics and most places around europe.
