I'm not sure why 48 kHz was used, other than it makes for a more pure
waveform, and is compatible with sound cards. You need at least 9600
Hz, as the 4800 Hz tone would need as a minimum 2X to get it sampled.
I suspect 16 kHz would work good in firmware A/D or D/A (without a
sound card).
The main
So does this mean the input sample rate is also 48 kHz? That would make it
harder for me because all the other modes use 8 kHz...

It's not resampled, it is generated at 48 kHz rather than 8 kHz as in
other
I'd be curious how well qradiolink generated FreeDV does against regular SSB
FreeDV. I don't have an SSB radio to check this, it's all SDR for me. The main
challenge I see is SDR frequency correction, since we can't be off frequncy by
much. Newer devices have input for GPSDO, but I don't posess
