[TenTec] Seriously OT: High Speed CW

[John Graves]

I am not good at the math but with G.723 you can get voice down to about 5 
kbps without a wrapper. So with Quad modulation, what baud rate are we 
looking at?  Does that translate to a baud of 1.25 kbps?  Can't we get that 
into a 3khz  window...That's all modems are looking into???
