It sounds like a technique I remember calling "controlled carrier".
The carrier power was reduced when you weren't talking, then was
increased with the audio in an AGC-like manner. Sounded a little
weird, but not badly distorted. The objective was to reduce the
average dissipation of the final stage, so smaller tubes and a lighter
duty power supply could be used.
No, "controlled carrier" was something else.
A quick web search shows that what I described is properly called
"dynamic carrier control". My mistake. I only recall having seen one
such amateur transmitter, and it was over 40 years ago. . .
