One of the most value added features of the TYT MD-UV390 Plus DMR digital two way radio is its capability for high level encryption. Of course, many DMR radios on the market offer encryption. The TYT DMR models such as the MD-380, MD-UV380 and MD-390 offer strong security with 128-bit encryption. The TYT MD-UV390 Plus is capable of AES 256-bit encryption.

Unfortunately, accessing 256-bit level encryption in the programming software is not at all intuitive. There is a little known trick to it, but once you know, you know. And we're going to tell you how to do it.

To set up the encryption, you will first need to put the programming software in AES 256-bit encryption mode. Here is how to do it in three simple steps.

1. Click on Privacy Setting and enter the encryption setting interface.

3. Click the "OK" button and the software will close. Run the software again, click on Privacy Settings, and there will be two tabs labeled Basic/Enhanced and Universal. The 256 encryption option will appear in the encryption settings.

All you need to do then is set up your encryption keys. After the first time, the programming software should be in 256-bit encryption mode when you run it.
