Yes that's exactly what I observed here. Glad your looking at it.

We had several complaints about TXG VCE messing up AM power levels, 
which resulted in the change. 

The way it works now is that the carrier will initially typically be a 
little on the low side. As you send audio through it, the 
peak-detecting ALC will take over and make the final adjustment to 
transmit power. This results in the peak power management with high 
modulation while not overdriving someone's attached linear amplifier's 
input protection circuitry. 

That said, we're looking into further improvements in AM transmit.
