Hi again to the group Jim and Fred both recommended lower power below 10 watts so the KXPA100 does not kick in. I tried it with my K3S when I got home from teaching the radio class and that does look as though it will work well. I hope to get over to his place this week end and get everything working.
I no longer have enough equipment to look for spurious frequencies but most of the time his KXPA100 would complete and the KAT500 would show very low SWR on the power meter I had along. The SWR on both my meter and the SWR line of the K3S display jump all over the place while the KAT500 relays are operating so I consider that normal. I am think of making a macro to turn the power down for tuning and if anyone know commands to turn the KX3 tuner off and the PA on in a macro please let me know and I will put it on one of his two PF keys. Thanks for the help and I will let you know later how we come out. 73 Ken.
