LinHT-hw

Linux-based, SDR handheld transceiver. OpenHT successor with greatly simplified hardware - no FPGAs involved. This project offers a replacement board for the Retevis C62 radio, greatly expanding its capabilities.

Supported modes (so far):

  • M17 - transmission and reception,
  • TETRA - reception only,
  • Demo 64QAM transmission at 2Mbps

Other modes can be added later.

Hardware

Work in progress. The device will use a System on Module (SoM) running Linux. The RF transceiver used is Semtech SX1255.

Software

The Linux image will be published later.
