I had previewed a raspberry pi board for hf radios with a high end codec at the fdim. This is for a new radio that i am building to push the limits of what my homelab capability can produce.
Pictures are attached.
There story so far is that there is a very low noise 24 bit codec on a custom board that plugs into the raspberry pi. The display is a 7inch capacitive touch screen.
The radio is a single conversion, very low distortion superhet without any amplification before the crystal filter and triple tuned filters for each band. Nothing is casual about this radio. Even the power supply had to be included to have low noise rating.
