I sure like the looks of that one, with a screen that's big enough to read.? by the time some of those "minis" get everything on the screen aged eyes can't read any of it.

It might be interesting to build the Pi right into the radio.? The Pi 4 with 8Gb of RAM & a keyboard & mouse plugged into the back of the radio sound like a sweet all-in-one package.? With the dual display capability of the 4 could even use a 2nd external display for the digital modes.

Sounds really good.

When I was using a Rpi with my uBitx for digital modes, I put the Rpi in a metal case and needed to run all the USB, power and HDMI cabled through ferrite cores to get the hash noise down to a low level.?

So, real metal may be needed for the case, with the Rpi in a separate compartment with a metal barrier between the Rpi and the radio.

Although it might be good solution to design a 3D printed case where the design includes a way to include and hold flat metal sheets as shields, maybe the 3d printed case can be an open frame that uses the metal sheets as the outer walls where no knobs, connectors and such are mounted. Where things are mounted to the case, the 3d printed panel (or laser cut acrylic panel) could have the precision, complex and visible cutouts holes and such, but directly behind is a more relaxed layout of cutouts and holes in the metal sheet behind it.

I wonder if any of those spray-on conductive coatings work well enough, as an alternative?

I've been watching Youtube videos on electroplating copper onto plastic. That might be interesting to try. I believe I saw some that used less harsh chemicals for the process, that I would like to try.
