Paul; When you transmit on either band, does the KPA500 display an asterisk on the left side of the display? This would indicate that the KPA is being PTT. If so, Place a wattmeter in the RF path between the transceiver and the KPA500. That should give a good indication as to the power getting to the amplifier (and thus KAT500).
I suspect there is no RF getting to the amplifier on the bands you are having problems with. Either that or no PTT signal on those bands. If this is configurable in the radio, then find the selection and set i two its proper value. Otherwise try to figure out why no rf is going out on those bands. 73!
