I've been running this now for a few weeks using a Pi 4B and the original Raspberry Pi 7" touch screen. It works very well and at the same time is still a work in progress. I am using a SDRPlay RSP1B with it. I have been working with the software author making some recommendations and he has been extremely responsive. The version available now as such will have some definite additions over what is seen in the video, to include direct frequency entry and squelch for NFM signals. A forthcoming version should also add step sizes, a snap to step feature, and maybe a user-entered customizable step.
This definitely makes for a nice portable setup, to be certain. A screenshot of my setup is attached.
The only thing I find is not able to be controlled by touch is the actual tuning. I have been using a mouse to do so, the mouse wheel allows for fine tuning to the actual frequency, so the step sizes and snap to step when and if they become available will be a nice addition.
The gain settings with the SDRPlay can be a bit tricky, but the right combination of IF and RF gain reduction can always be achieved, and the waterfall and spectrum levels are fully adjustable as well.
As in my case this is only being used for receive only, I edited the sdrberry_settings.cfg file and customized all of the band buttons to my liking. This can be a bit tedious but worth it when all is said and done.
Here is a direct link to the SDRBerry github page:
