The Narrow Bandwith TV Association is a good place to start:
or via the mirror on the BATC web site: http://www.batc.org.uk/index.htm
A slight, further, diversion to http://www.dfm.dircon.co.uk/index.htm leads
to some interesting items on use of modern techniques to recover early
30-line mechanically scanned TV recordings.
An interesting diversion when local QRM becomes unbearable!

SNIP. Another example of this is Victor G3SDQ who is currently trying
to work me on 136 from Leyton who has just built himself a 625 to 35
line converter so he can watch his favourite programmes on a Baird TV.
Does anyone know if the info about this is on the net somewhere - could
be interesting reading!
