I'd like to gather information on which "budget and entry-level" DMR radios have encryption compatibility between models. Hopefully we can use this thread as a repository for this information across manufacturers and models. If anyone has experience in this space, please let us know. It would be helpful to capture the radio models, firmware revs, and the compatible encryption protocols.
This inquiry stems from some recent radio purchases I made. I bought some Retevis N30D mobile radios and a Retevis RT73 mobile radio, hoping to use them together with encryption in under a Part 90 license. Both radios advertise AES256 encryption, but digging a little deeper on the Internet reveals that the RT73 may only support ARC4 encryption. The N30D programming software supports inputting full 64-character AES256 keys. However, the RT73 programming software's encryption menu only supports a maximum of six two-character (hex?) values for each key. My next project will be to try to use one of the lower encryption levels on the N30D (which aren't identified by protocol) to try to match the RT73.
I have notes from a Retevis website I saw a while back that seemed to indicate these radios are encryption-compatible: RT73 & RB22, HT1 & RT43, RT90 & RT3S. However there weren't any details on what settings to use to make them compatible. I can't find that website now though, unfortunately, and I didn't capture the link.
