[Elecraft] K3s missing right channel in "nor xxx" mode / digital level too low - BUG?

[C G]

Hi Al,

Thanks for your answer. Can't explain the logic behind this behavior. Would it be a bug in firmware?...
Maybe this could be on the wish list then. For both requests ("nor" stereo AFX *and* low digital level).
Santa's gone, but who knows?

Would it be possible to rise the output level to AES/EBU Broadcast Audio Standard, i.e. -18 or -20 dB (depending on countries), or even more, as dynamic is lower for speech and therefore headroom can be reduced without clipping consequences. That would mean additional A/D gain : +10 dB, + 12 dB, and maybe +24 or +30 dB boost for weak signals?
