i have a icom f21 radio i was wondering how to program it as in change the frequency. i have the usb cable but no software.
You need the software. ICOM can sell it to you.
i have tried looking for the software and cant find it can you send me a link
is there a free alternative
Commercial software. You must pay… order it from Icom. It will fully program this radio. You also need the cable to program it.
