I've just gotten into shortwave radio and while I like listening to all
of the chatter, I am particularly fond of the noises that I am picking
up. There just seem to be so many types. I wish I knew which ones are
nonesense atmospheric/mechanical noise and which are meaningful. I hear
a lot of pulses or tones at regular intervals (and that are not the UTC
time broadcast). I wonder what these are.
