Well done, mate.
I see that you are working on new systems.
Maybe you would like to add Tetrapol?
I'm sending transmissions of this technology (probably) - in the attachment.

Best regards!

Hi

Tier 2 + 3 is that what every Commercial and Amateur Radio DMR like Hytera, Motorola,... use.
DSD+ show the FTMA but dont decode Audio.

Hello everyone
i invite anyone that have Hytera DMR radio to help me for decryption test
currently software under debugging and development, then you can't directly test software
but you can help me by recording DSDplus raw input audio (by pressing r key and then after traffic ends press again r)
or by recording baseband sdrsharp signal currently i focused on basic privacy then it is better for me that BP is be used
Thanks
