[Elecraft] W2 Wattmeter

[Eric Swartz WA6HHQ - Elecraft]

Guys - The W2 is fully user adjustable for calibration. Please see the 
manual for details. Basically, if you wish to adjust its absolute level 
up or down to match a favorite 2nd Wattmeter, you can easily do this by 
sending +/- serial commands to it from W2 Utility.

My W2 is adjusted to almost exactlyu match my home Bird WM (which reads 
differently from another of my Birds...) ;-)

73, Eric

I do not have the lab equipment to measure accuracy, but suggest that when any meter is placed between tuner and antenna with jumpers there will be a difference no matter what meter one uses.  I think the meter rollout was under pressure to get it to production and not quite ready for release.  I wouldn't be that concerned now.  I use the 1.5 kw module (something like that) and I monitor my 1.5KW amp to the antenna.  With the amp in and out of circuit, the K3 and W2 seem to be close; remember that jumper length, etc., will cause some difference!
