Yes, I have a cable that has the PowerPole connections to the K2/100, and a separate coaxial jack for the KAT100.
I switch the power supply on, which means the KAT100 has power, then switch the K2/100 on, which powers up the combo. So, yeah, I have power applied to the KAT100 before the K2. > On Aug 5, 2018, at 4:39 PM, Jerry Ford <n0j...@gmail.com> wrote: > > Hi Bill: The K2 / KAT100 has a strange start up procedure you have > to follow or the KAT100 will do strange things like you describe > > You have to apply power to the KAT100 before you apply power to the K2. > IF you start the K2 first, you get all kinds of strange things going on. > > I have my KAT100 in a separate enclosure and on a separate power supply.
