That depends entirely on the type of encoding and modulation used,
doesn't it?
Can you categorically say that digital voice can *never* outperform
SSB?
No. One day it might. But not yet.
Even if the data rate is slowed down?
If there's anything that deserves spectrum space for experimentation,
it's digital modes, not analog voice modes.
DId you read the review in QST about the digital box you attach to your
HF rig?
It sounded like a pretty good thing, until they pointed out it's fatal
deficiency near the end. I shouldn't b that harsh - if it is a fixed
frequency application, then it won't be too bad.
You just have to be listening at the right frequency at the beginning of
a transmission, or it's no hearee! My guess is that anything that will
allow you to pick up a transmission in the middle of a transmission will
boost the bandwidth requirements up quite a bit.
