[Elecraft] W2 Questions

[Phil Hystad]

A few questions about the W2 meter:

1.  The posted accuracy is +- 0.5 dB which I calculate as about +- 12 %.  Is this full scale accuracy and if so is half scale possibly more accurate or is this the most accurate the meter is likely to be.  I am not even sure if it makes a difference for full scale or half scale for a digital meter so that part of my question may be moot.

2.  What does it take to achieve an accuracy better then 5 % (for example), and is it possible to achieve an accuracy of 1 % or better?  I am curious as to where the money needs to be spent in achieving such accuracy.  Is it in the directional coupler?

3.  I am thinking that the company that can build the best receiver on the market (the K3) can also build the best meter.  So, would Elecraft principles consider a future super-accurate, best on the planet, amateur radio RF/SWR power meter?  Oh, I think a current meter would be cool too.

And, I know that having meter accuracy is of little importance in ham radio but there is some kind of deep seated quirk in me that wants accuracy just for the heck of it.  Certainly 5 % is achievable, right?
