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???

It would be kind of fun to mess around with 6kc-10kc bandwidth digital

anyone?

Given the high level of concern for broadband SSB shown on the list
recently, I thought it resonable to make the following proposition. As
we all know, the width of a CW signal increases as a function of the
switching speed. Given that high speed CW is therefore occupying a
larger bandwidth that I at 5 wpm, should there not be some quiet corner
devoted solely to slow speed CW. We could then operate quietly and
efficiently, and feel good about only occupying a proper amount of
bandwidth.
