I think it will go all the way to zero; at some point the drive level gets
too low to forward-bias the final amp. Connect a hi-Z voltmeter (such as a
DMM) and an RF probe to the antenna jack and measure the RF voltage (Vrms).
You can then calculate the power from:

        P = Vrms * Vrms / 50

assuming you have a 50-ohm dummy load or well-matched antenna.

I'd like to know your results.

72,
Wayne
