What happens if you deliver asymmetric peaks, say 130% positive
and
around 95% negative, to the rig? Sounds the firmware is
programmed
with the assumption everyone runs symmetric up and down.

According to Doug's write-up, the 130% part of the waveform will
be gain set (compressed) to get the 100% modulation peak and the
95% waveform will be further down in level - like +65% .

"If the baseband voltage
had a higher negative peak than positive, 100% downward
modulation would be reached in compression before 100% upward
modulation could occur."
I'm sure the reverse is true as well.
