ICOM now offers a simple time setup program for the IC-7 series transceivers. The ST-4003W Windows software allows you to set your transceiver’s time via your PC.

The current list of compatible radios as of 11/2021 are the IC-705, IC-7100, IC-7300, IC-7600, IC-7610, IC-7850, IC-7851 and IC-9700. Just connect the radio to your PC with your USB cable. USB port types differ so check the transceiver port setup to prep your cable.

ICOM recommends reading the “ST-4003W INSTRUCTIONS” prior to installation.

Since I already had the cable between my laptop and my 7300 I just installed and ran the ST-4003W software.

Here’s a YouTube video that explains the software installation and execution.
