I would like the W2 wattmeter to be able to display "delivered" power, that is, forward power minus reflected power.
You want N8LP's excellent LP-100A. I had lusted after one for quite a while, and bought W6OSP's unit after he died for about half price. The LP-100A supports two couplers, which can be deployed on the outputs of both transmitters in an SO2R setup, or on input and output of a power amp. The LP-100A measures the complex Z at the coupler, so it can measure the input Z of the amplifier under dynamic conditions.
Now that I can measure power more accurately, I am able to run a dB or more closer to legal limit when I want to for contesting.
