We’ve been busy with LinHT development recently, as the plan is to showcase its Proof of Concept at the upcoming M17 Conference 2025. Here’s a quick peek at what we have so far. Our printed circuit board is supposed to fit inside a Retevis C62, replacing its mainboard. We intend to use the radio’s original battery. PCB design by Vlastimil OK5VAS (work in progress).
M17 reception/transmission along with TETRA reception have been tested and proven to work. Additionally, a dummy 64QAM transmission was also successful.
One of the best things of our design is that the System on Module used runs Linux and you can SSH onto it through USB-C connector (it enumerates as an RNDIS/Ethernet Gadget). You can basically drag-and-drop your flowgraph and completely redefine your radio or add new capabilities to it. How cool is that? If that’s not enough for you – the SoM includes a Neural Processing Unit with TensorFlow Lite support that should be enough to enhance Codec 2 decoding process.
And yes, the device runs Doom, at least the prototype does, with some crippled framebuffer 🙂
