There seems to be some interest in attemptimg to decode unencrypted TETRA witha a £6 RTL dongle, I will post my own how to perhaps later on when i get time, but all i did was read and do what it says here, and you don’t need me to re-tell you anything more than it says in the linked how-to below really..
