Chris,
With respect this sort of thing is good for black box users.
But my feeling is that generating "vast" amounts of power then wasting it in an attenuator is not really true QRP.
I think reducing power output on all QRP Labs TXs can be achieved by reducing PA voltage.
I guess there will be a limit, even with 0 volts on the PA something will get through.
