There was a time when, if you were very lucky and had a lot of very expensive equipment and an antenna the size of Blackpool Tower, you could communicate with people on the other side of the world. You were a radio ham. You would have a call sign like a mathematical equation and would get very excited if you could contact someone in outer Mongolia and ask what the weather was like. Such a person was Harold Ryall (W1NKW) of Nahant, Mass. and here is a picture of him in his radio shack. Just why I should have his photograph in my “lost and unwanted” box is beyond me – perhaps I should call him up and ask him.
