    © 2010 All rights reserved CAT PORT & 2 CAT PORT The CAT channel is used by the application software to control transceiver frequency, mode, T/R switching and many other parameters. The application communicates with the radio using a serial protocol. Although most modern radios implement some form of serial control, nearly every radio implementation is different.
