SDR-SLC HF transceiver

Open hardware for a 1.8–30 MHz HF transceiver you can build yourself — receive and transmit — designed to give serious performance at a super-low cost.

Open schematics and firmware

The complete schematics and firmware are published openly. Study them, build the board, load the firmware, and connect it to the SDR-SLC client over your network. Modify it freely for your own station.

• Coverage: 1.8–30 MHz, all HF amateur bands from 160 m to 10 m
• Receive and transmit
• Connects to the client over TCP/IP, discoverable via Bonjour

Prefer not to build HF hardware? The client also drives RTL-SDR and BladeRF devices through the SDR-SLC daemons — see Software.
