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. ;)
