Radio, television, amateur, domestic, international - whatever. I don't spend as much time as I used to pursuing this interest (I used to play with Short Wave radios, aerials - indeed anything which had a transmitter or receiver inside of it). Nowadays I content myself with more passive pursuit of this interest (if that isn't a contradiction in terms), although in the past I have worked as a part-time television producer for Manchester's Channel M and have made my own films, edited and been cameraman for others.
