NEW Hackable HF SDR for the Raspberry Pi by VU2ESE
Dave Slotter, W3DJS
I just came across this Hackaday.com article about a user-modifiable HF SDR that should cost less than $100 USD for the Raspberry Pi here: https://hackaday.com/2021/08/06/sbitx-hackable-hf-sdr-for-the-raspberry-pi/
It comes from the same developer as the ubitx radio, VU2ESE, so points in its favor!
