I use an Alpha 4510 Power/SWR Meter and it does have a power
delivered/forward setting just for that. That setting takes all of these
factors into consideration for the final product it reads from .03-3000w.
That is the reason for my trusted Oak Hills Research WM-2 QRP wattmeter
still in line for my KX3.

Subject: [Elecraft] W2 Wattmeter idea

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.
