George, Thanks for your suggestion. That will work. For some reason I was under impression that I would have to TURN ON the KAT500 first. My KAT500 will be also connected to 12V buss. My interpretation of "applying power" was wrong. I just received my KAT500 KIT. Thanks again :) Mark WQ7X "Mark, My understanding from the manual is that the KAT500 must be on when the K3 is turned on for the Aux connection to work properly. In my shack this is accomplished by connecting the KAT500 directly to the 12 volt buss; that way it is already on when I turn the K3 on. This works well for me. Probable doesn't matters if you elect to not use the Aux cable connection. George AI4VZ"

So, does anybody know if KAT500 MUST be turned ON FIRST and than K3 - otherwise K3 will not initialize correctly (with DB15 cable connected as it should). Is this still the case? I don’t like it as I have other antennas that will not be connected to KTA500. I will not always need KTA500 to be on line. This just doesn’t make sense. KAT500 will be connected to pos. 1 of the antenna switch. Could firmware be changed in order to correct that?
