[Elecraft] Noisy radios

[Jim Rhodes]

Years ago one of my students in my license classes came up with what he
thought was a great idea. We had been discussing the difficulty many hams
have in finding places to live that allowed antennas. He thought it would
be a great idea to start up a development just for hams, so there would be
no restrictions in the deeds against antennas. I had to tell him that the
last person I want living next door to me is another ham. Which of course
led to another discussion.
