I like SDRs too, but then you probably need at least a laptop to get enough computing power to do a good job.
This is a bit of a misconception. Single-board computers (SBCs) have now become ridiculously fast:
"The Raspberry Pi 2 Model B is approximately equivalent to an Athlon Thunderbird running at 1.1GHz; again, it has the much higher-quality graphics, which come from using the same GPU as previous models. The Raspberry Pi 3 Model B is around twice as fast as the Raspberry Pi 2 Model B, depending on the benchmarks chosen."

The Pi 4 is super fast, but also needs a heatsink...
A display can be had here:

Here's a demo of someone putting it all together:

Here's where we need a volunteer to put this onto a SD card for easy use by those not familiar with Linux, etc.
My plate is full, but I'd be glad to test it out and give feedback.
