Re: HF SSB

There is still a moderate amount of business in HF SSB, the main
reason that people are going digital on HF is for anti-jam and secure voice 
type things.

HF high speed data modems are starting to crop up.  That's fairly exciting. 
HF e-mail as well.

Anyway, one of the things I often wonder about is why since DSP is getting 
so cheap, why most "ham" type radios still are FM only.
It's easy to (de)modulate SSB in a cheap DSP nowadays..
