IIRC the original design incorporated an algorithm that increased the
carrier level when the modulation looked like it would exceed 100% and
briefly 'follow' the peak with as much carrier as was needed to accommodate
the peak. This weekend, I'll check the PEP on my LP-100 Watt meter to see
if there is any sign of that action. In that case, we may indeed be getting
near 100 Watts PEP even though the resting carrier shows only 11 Watts.
