I have this radio. Yes, you can set designated codes for rx and tx. You can listen (rx only) to 70cm frequencies out of the box, but no other frequency ranges.

Hello. I’m the newest of newbies, but I do have experience with this radio and with the software on both windows 10 & windows 11. I tried windows 10 first due to all of the reports of difficulty with windows 11, but windows 11 works just fine. I didn’t require a driver for either OS. If you’ve made sure the USB device is working properly in device manager, selected the correct com port, and chosen the correct model, I think the answer could be as simple as making sure the screen isn’t dark when you either read from or write to the radio.
