Right, the masochist channels :-) Or, perhaps, the apocalypse
practice channels.
It's a bandwidth thing. :D There are digital modes (like PSK31) that
are legal in the code bands due to their narrow bandwidth (assuming
your radio's mike isn't live and modulating audio over your PSK
signal), and you would not believe how many CW signals can fit
comfortably into just a few hundred Hz of spectrum. Plus, you can get
out on HF with a couple of 50 cent transistors, an Altoids tin, and
maybe a 9 volt battery if you set up your antenna and feedline
right. ;)
