Now you are delivering distorted audio to the modulator, probably with
some DC offset that isn't supported by capacitor or transformer coupled
audio stages.
To get asymmetrical modulation without over modulating going negative,
you have to introduce the asymmetry AT the modulator, not before and the
modulator has to be DC coupled at audio.

Merle,
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.
