CAT control
HS2 has a CAT system, so you can control the walkie-talkie with a personal computer. Multiple control operations can be fully automated with the click
of a mouse, and control of third-party software packages (such as radio log software for games) is also supported so that HS2 can be used for
communication without (additional) operators. The CAT protocol is compatible with FT-817, so the MODEL of FT-817 station is selected for CAT
control. The CAT control USES a TYPE-C USB cable to connect to the computer, and the serial driver works only on Window 10. The USB cable is also
integrated with the sound card, and only one USB is needed for CAT control and data transfer. HS2 only supports Windows 10 operating system. SDR
