The KPA500 can be set up to either monitor the Kenwood's interaction with a logging program by "listening" on the serial port or by polling the Kenwood when you do not have a PC connected to the Kenwood. The KAT500 cannot do this and so can just change frequencies when it measures the transmission frequency.
