[Elecraft] W2 Wattmeter idea

["Milan Gütter, OK7GU"]

Dr Vic,

Iam using K2 and LP-100A Wattmeter for my remotely controlled station, 
both works fine.
The K2 accuracy for SWR upto 2 is enough good (10%).

If you need more sophisticated Wattmeter, use the LP-100A.

LP-100A can indicate the pure FWD power. And many other parameters.
