And I started this thread by pointing that out, and saying "wouldn't it
be nice if the W2 firmware could show Pf - Pr in the LED display." I
don't have screen space for yet another application.

Hi Folks:
Been reading this thread and just wanted to mention that the Elecraft W2
Interface program (
http://www.elecraft.com/software/W2/elecraft_w2_software.htm) shows both
forward and reflected power quite nicely.

The power delivered to the load really is forward power minus reverse
power. You can see that by imagining that you disconnect the load
completely (infinite impedance) or short it out (zero impedance). That
means no power can be absorbed by the load.
The wattmeter reads equal forward and reverse power, so that forward minus
reverse equals zero, as it must.

As well as not all the reflected power being re-reflected, the forward
power measured by the coupler is not the first time forward power, but the
sum of all the re-reflected power, as well.
