A micro bug, won in a competition in a magazine called Soundwaves. Surprisingly, as his mum rang to confirm, it reached my friend's house, a mile away. He felt that the audio was rather good and felt the minimalist design might be the reason. Coincidentally, I came across it during a tidy-up the other day. Does anyone need anything relayed? Obviously, I moved on from there, to a 5W Dutch rig, that I went to a back street in North Amsterdam to buy. And then got hold of the Radio Jackie book of transmitter designs. But you asked about the first one. I'm glad you said broadcast, whih avoids opening up the topic of what classes as a "pirate" broadcast - need it entail a ship, for example.
