TETRA decoder

In my days of work, I ran the hardware teams designing TETRA hand portables. I actually knew quite little about TETRA as most was implemented in software. What I knew I have forgotten!

These days, you can get freely available software that can decode modes like P25, DMR and TETRA.

TETRA was very popular with security systems as it was hard to intercept. Not any longer.
