Thinking about getting into DMR.

Encryption is not allowed in the USA amateur service. Businesses licensed in the business band are allowed Encryption.

I do not need anything special to load the key into my XPR5550e and XPR7550e radios. I just enter the encryption key with the CPS.

That makes it easy. One other forum member has some Kenwood NX5000's and he needs an external hardware key loader. The keys are store in a computer file, I believe, in an encrypted format for security. That's all handled by the key loader software.

Many of my older Kenwood digital radios have an option board access port on the back side for plunging voice scramblers and digital encryption options.

I've also found some info on the add on encryption used my some of the Kenwood radios in case anyone has an interest.

I also have the hardware manual for a third party Voice Inversion Scrambler with Midian’s Kryptic Signaling with the schematic.

That's true. However a number of people on this forum also hold Part 90 licenses where it is legal. Unfortunately I'm not one of the lucky ones who qualify under the FCC rules to get one. Not exactly a topic for Ham or GMRS, but legitimate for the proper service.

Don't forget that a fair number of commercial grade radios already have encryption built in. Just can't use it on Ham and GMRS. Of course when the SHTF, and government reg's are out the window, encryption might be the one thing that will save your butt from those that want you and or your stuff.

Yes and no. The NX-5000 radios come with DES 4 key option out of the box, and those keys are software loaded. DMR Enhanced Encryption (ARC4) is an add on, but those are also software loaded. If you want AES, or more than 4 DES keys, you need the AE31k crypo module, then AES & DES are loaded via either hardware keyloader, or KPG-AE1 software.

NX-3000 don't have anything out of the box. DMR EE is same as 5000, add on + software load. AES/DES need crypto and hardware or KPG-AE1 software.

Kenwood VP8000 & VM8000 are entitlement based encryption, hardware is in the radio by default. AES/DES is keyloader or KPG-AE1, EE can either be done in programming software, or loaded via keyloader. I did have an issue with hardware loaded EE keys though.

Thanks for correcting my miss understanding.
