[Elecraft] W2 Wattmeter

[Roy Morris]

Why would I need a DCHF-200 coupler if the DCHF-2000 would provide low power readouts?  The display unit has the bargraph ranges of 2, 20, 200 and 2000 watts.  Why not buy two DCHF-2000 couplers, one between the K3 and linear amp and another between the amp and antenna tuner.  This way one of the couplers could also be used with a second QRO station in the hamshack.   I just don't understand why a DCHF-200 coupler is needed unless it can provide accurate power readings under one watt that the DCHF-2000 maybe cannot.  Roy Morris  W4WFB
