My PowerMaster tracks very nicely down to 2.5 watts (within a few percent of my
TekTronics TDS-2022). 2.5 watts is the lowest power I can get out of the
IC-706MKII that I'm using for a source. Somewhere around here I have a power
6dB attenuator. If I can find that, I'll look at lower powers. The
PowerMaster does stop computing SWR when you get below 4.5 watts though. So I
would definately not consider it a QRP SWR meter. The PowerMaster does have
diode drop compensation (I got a chance to look at the schematic).
