[Amps] FW: Decent HF directional coupler for RF power meas.

[Phil & Debbie Salas]

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).
