Pierre,
You can test the inductors and capacitors using these menu entries. Here’s a
general approach:
1. Connect a dummy load to the antenna jack.
2. Set the KX2 for 40 meters, about 3 watts.
3. With the ATU in BYP (bypass) mode, a TUNE should report SWR of 1.0.
4. Selecting ATU MD = L5, L6, L7 or C5, C6, C7 should make the SWR go up
(larger the reactance, the greater the SWR change).
5. L1-L4 and C1-C4 can be tested in the same way, but you’ll need to use a
higher band, such as 17 meters, to clearly see the impact of these smaller
reactances.
6. I believe that the Ct test position also throws in a capacitor and possibly
an inductor to see the effect of switching the network from C-in to C-out. This
is likely to be observed best on a higher band.
