Cheap, easy to use SDR dongles are an immensely powerful tool for learning about radio technology. However, building your own SDR is not something too many hackers are confident to tackle. [Ashhar Farhan, VU2ESE] hopes to change this with the sBITX, a hackable HF SDR transceiver designed around the Raspberry Pi.
This project is not for the faint of heart, but the downstream benefits are amazing: It can be easily extended through software updates, you can hack the software to experiment on your own, parts are all replaceable, and it potentially costs under $100 to build vs paying $2,000 or more for a commercial radio. The downside is the PDF does explain it better, but there is still no easy 1-2-3 step guide available, but I'm sure someone will come to the fore to also produce that.
Ashhar has also produced an open source buildable antenna tester.
