Retevis Retevis NR40 Encryption not working

[zmanley]

I recently bought a pair of Retevis NR40's. I programmed them and set up digital channels, with keys and turned on AES encryption. I made sure everything is synchronized between both radios - frequencies, encryption keys, settings. I made sure the firmware is current and the same between both radios.

When I am on a digital channel with AES ENCRYPTION, I get no voice. About 25% of the time the receiving radio gets a green light and the signal strength indicator comes on, so I know it's communicating on some level, but always no voice.

Is anyone else having these issues? Dies encryption work for ANYONE? since I've tried everything as far as troubleshooting goes (by Retevis) I'm having replacements sent. I'm just worried that the new radios will have the sane issue.

Thank you!

Purchase an RTL SDR key and use the DSD-FME software with your AES key.
If AES is configured correctly, you can hear your voice through the DSD-FME software. Do the test with your two radios.

So suppose I hear it after plugging in the encryption key to the SDR - what dues that tell me?

What does it tell me if I don't - where does the fault lie?

How close are the two radios when you test them? You might be overloading the RF stage by having the radios too close to one another.

I hope these tests are being done on commercial frequencies with a business band license. Encryption on amateur radio is illegal.

use the following command :

dsd-fme.exe -Z 2>log.txt

and you'll post the log.txt file here
and we'll tell you if AES is working properly.

Software defined radio equipment alone isn't going to contend with that encryption - keys or no.

That isn't germain.

When you go to the doctor and say, 'I'm sick, nothing is going right, help me.'

The doctor then says, 'Okay, we'll start by taking a blood test to see where the problem is.'

Then you tell him, 'No, doctor, a blood test won't help me.
List all the possible illnesses imaginable and tell me how to treat each one.'

What do you think the doctor would respond?

It's not a whim, it's the basics. When you troubleshoot RJ45 network cables, you also have a special device to find the problem:
