A few weeks ago I posted this problem, worked on it a bit, then got distracted into other projects. I am now back trying to resolve the faulty SWR issue with My KX3. The problem only occurs on 160, 80 and 60 meters.
Using a known good dummy load and cable the indicated SWR on the KX3 is high --- 1.8 to one using 10 watts. An external wattmeter/SWR meter shows the Dummy Load as a perfect load. The reflected power needle does not move. I have done repeated Power Out Calibrations with the KXPA100 (not relevant, I know). The KX3 shows the same faulty SWR Readings with or without the KXPA100. Of course the ATU mode is in bypass. But, when the ATU is active, it matches, shows a proper SWR briefly, then shows the faulty reading as the rig transmits. It was a factory built unit S/N 4932. I'm stumped. I guess it is time to send it home for healing.
