    160m FT8 RX overnight

    TETRA decoder

    Posted: 19 Mar 2022 11:59 PM PDT http://g3xbm-qrp.blogspot.com/2022/03/tetra-decoder.html

    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.

    home in Cumbria. They are retiring. They still have some components left.
