Re: Ubitx and raspberry all in one. Digital mode FT8 - IK1ZVJ. #ft8

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.

That's awesome.

I just picked up a 'like new' Collins power supply cabinet for a KWM-2 series radio at a hamfest. I am thinking seriously about a similar build, with a uBitx mounted inside, but hadn't thought about putting a raspberry pi in there also... interesting idea.

The case looks like this, but there is no speaker installed:

The project stems from my passion for digital modes. The union between ubitx and raspberry works well. The LCD screen is mounted on an old CD mechanism so as to obtain automatic ejection. The project includes a dual power supply with a built-in power supply and battery power for portable use. the commutations foresee the functioning only of the ubitx, only raspberry, together to use the digital modes. On the raspberry WSIT-x are loaded for FT8 and FT4 and FLDIGI for PSK and RTTY.

The enclure is a rack 3U (9 cmx40cmx43cm).
