No, phones are a lot worse than that. The specified phone
passband is 300 Hz.....3400 Hz, thus a total bandwidth of 3.1
kHz. 8 kHz is the sampling rate used for digitizing in phone
systems. Actually, you can get along with a a much lower
bandwidth. When I'm on OSCAR, I use a rig with a mechanical
filter with 1.73 kHz bandwidth. This works well, but you lose a
lot of personal voice characteristics that way. However, you can
chat away very well with that ( I know, because I've doing that
since 1984....quite a lot of that in Japanese....and my RX uses
such a filter, too ).

Not much, actually. You can compress voice brutally until it
sounds robot-like, but it is still intelligible. You even can
chat rather comfily using such brutal compression ( down to 2
kBit/s or less ).

That's what I stated some months ago on this list.....

Ah, if somebody wonders, my ham call is DB8CO, and I'm ex 7J1ADO
