High quality, fully screened (shielded) cable, approximately 2m/6ft 3ins in length, facilitates control of your Yaesu transceiver by your computer. This versatile cable enables various functionalities, such as utilizing remote control software like Ham Radio Deluxe, editing and backing up memory channels effortlessly, and integrating with contest and logging software to fetch operating frequency and mode directly from the radio. In scenarios involving satellite communication, the cable allows automatic tracking of transmit and receive frequencies, compensating for the Doppler shift.

The cable features a DB9 female connector on one end, designed to connect to the CAT socket on the radio. On the other end, another DB9 female connector is present to link to the PC's COM port. Additionally, the cable is compatible with a USB-to-Serial converter, catering to computers that lack a COM port. It is important to note that while the CAT cable offers extensive control capabilities, it does not function as an audio interface for data modes.
