In the ongoing work to bring TETRA to Australia, We are in the process of setting up a bridge that uses a RTL-SDR to receive TETRA, demodulate it and pass the voice audio over to a Zello channel.
At the moment the channel is receive only, but it is useful for us in range testing and getting an idea of coverage options for TETRA!
We are looking into getting a higher powered mobile unit and configuring it for two-way bridge with Zello if there’s any interest, to help bring more people into the mode..
