"Those are good points about the trigger and perception of accuracy of the W2. I have yet to see field test data of the W2 in regards to accuracy of the Wattmeter and SWR indications."
According to the manual the W2 has an accuracy of +- 0.5dB typical (nothing about worst-case). This is 10-12% accuracy. Not as good as the PowerMaster/LP-100A/Telepost class of wattmeters that use NIST-traceable cal equipment (which should get you more like 3-5% accuracy). Of course, those are $100-$150 more expensive than the W2. If you use the W2 LED display, your perceived error could be greater than the 10-12%. As an example, if you really have 100 watts and the W2 reads it 1/2-dB low, then possibility only the 80-watt LED would light. So this would give you a 20% reading error. Maybe the ARRL will do a review sometime soon.
