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.

I just ordered a W2 wattmeter, haven't received it yet, and I already
want to change something!
It displays forward power and SWR. When the SWR is 1:1, then the power
output of the transmitter is equal to the forward power. But when it is
greater than 1:1, then the actual power output is the forward power LESS
the reflected power.
I would like an option to display this output power, forward less
reflected. This could probably be done in the firmware, a "SMOP" as
Wayne likes to say.
I realize that this does not tell you the power delivered to the
antenna, for which you would need to know the line loss. But it is still
a more useful indication than just the forward power.
