[Elecraft] W1 Watt Meter

[David Yarnes]

Maybe you could consult with "Cy, The LED Guy", about identifying some 
better ones.  I think the mod has merit, but I wouldn't know what exactly 
should be substituted.  Cy shows up at most of the QRP gatherings around the 
country (he comes all the way from Maine), even Pacificon!  I suspect he 
would have some good suggestions, and of course, he could probably sell you 
what you need.
