Interesting stuff.
Slowscan TV used to be my bag - along with RTTY and a couple other data modes. All this, of course, on 11m SSB.
I remember one particular day, halfway between sending a SSTV image to a pal across town, when his station suddenly went dead. It turned out he had a visit from the DTI people, there to confiscate all his radio equipment. Thirty minutes later the same bunch were banging on my front door - obviously for the same reason. I didn't answer, and never heard from them again.
So like a prat, I decided to make it all legal. I was already armed with enough know-how to get me thru the RSGB test, but I wanted more than that - I wanted the fun of a CW-based QSO. So I set about learning the code. That was round about the time when the Internet started rearing its ugly head. By that time 99% of Amateurs had abondoned CW anyway, so I was pretty much left high and dry. Consequently, I never bothered taking the Ham exam.
The Echo-Charlie Band around 6.5MHz was also a good one. Been too long since I was there - not sure if it still exists even. I built my first AM transmitter for that band from a couple of EL84s tubes. Last time I was there the SSTV scene was buzzing.
I've still got all my radio gear - mostly 11m stuff. And now that the UK television is going hi-def', then maybe all us 11m ops' can get going again - without fear of causing TVI.
