"So can anyone see what I'm doing wrong" To connect a WM-2 in circuit with the KAT2, you'd need to open the case and measure the power between the RF board and the KAT2 board. This is simply not necessary. Use the power measurement capability of the KAT2.
If the load is very close to 50 ohm resistive, you can hook it up the way you imply you've got it, and get reasonable measurements. You say "the SWR is pegged". I don't know what that means. The KAT2 will show various SWR ratios (not forward and/or reverse power) while in AUTO mode, so you may be discussing some function/feature of the WM-2. How does the KAT2 seem to work with the WM-2 out of the circuit? Yes, ANT1 is indicated by an extinguished ANT2 enunciator. "And explain it to me so I can understand it" Power meters, such as the WM-2, expect to see 50 ohm loads. If you have a different load, the power meter will display wildly different values. A transmatch, antenna tuner, conjugate match, or whatever you call it will show 50 ohms on the input (if adjusted correctly) and whatever the feedline presents on the output. The only way to get a meaningful power measurement is in the input, 50 ohm, side. Of course, this won't take into account any inefficiencies in the tuner. To do that, you'd need to analyze the impedance at the feedline, measure the RMS voltage at that point, and do some arithmetic WAY over my head<g>. I'd suggest going with "Don't ask, don't tell" - say what the K2 says.
