I think it means it will dead key at 150 but will modulate up to 300.
It's like SSB power output but on AM.
Don't know why it is done though.

Then there is the VooDoo 300 B
it is a base amp and puts out about 150 watts with 300 watts of swing.

If it puts out 150 watts, then what do you mean by "300 watts of swing" ??
