The future is here: LinHT booted up successfully for the first time. We believe that Software Defined Transceivers will be the next big trend in amateur radio.
LinHT is the most important hardware project in Amateur Radio today.

The test device has no RF amplifier (although we will include GRF5604 RF amplifier in the next revision, see this). The output power of this test setup is around 5dBm. Frequency range: 420-450MHz (UHF).
While some doubted that such a design is even viable, we continued our work tirelessly. Big shout out to Vlastimil OK5VAS and Andreas OE3ANC. The project would not be possible without your help, guys.
The device is open source hardware. The PCB design is available here.
Total cost for a prototype run:
– $490 for PCB+assembly at PCBWay (5 pcs.)
– Retevis C62 (donor)
– $469 for SoM, 5pcs.
