Alan,
Yes, set the KXPA100 tuner to bypass - switch on the front.
You will be using cabling as shown in Figure 4 page 11 of the KAT500
Owner's manual. The "output on transceiver that provides closure to
ground on transmit" is the RCA jack on the rectangular box in the cable
between the KX3 and the KXPA100.
Note that the RCA cables which provide keying for the amplifier MUST be
routed first through the KAT500 and then to the amplifier - that allows
the KAT500 to disable keying the KPA500 when it is tuning.
