Sub 2400bps coding

Does anyone have any recommendations on speech coding algorithms
<2400bps? I need a low data rate codec for an amateur radio
experiment I'm planning. I've been looking at MELP, but I noticed the
DoD are looking for 600bps algorithms. I've also noticed TI are
selling DSPs for toys with 1000bps MELP codecs.

Can anyone give me pointers to papers/code?

What's wrong with 1200 bps DOD version of MELP?
