Building a Software Defined Radio (SDR) with LimeSDR

A bit expensive for what it is, but rarely this is a near-fully-standalone (i.e. on-board signal processing) general-purpose SDR, based on LimeSDR and Pi Compute Module 3:

I think this USB-based one is much better value though:

but the standalone one may end up being better supported, since the OS/application environment is more controlled. And for SDR, that can be a huge difference in usability.

Looks like a very cost effective SDR.

You provided some really great links to parts, and I can see a CNC router next of your tool list to help with these builds.

Great build.

Only took you a weekend? I would have guessed at least a week.

Well done.

This looks amazing Shabaz! In the absence of a proper spectrum analyzer, I want one! To be honest though, even if I had a SA, I would still want one!!!

A very well done job Shabaz.

I am almost new to this range of frequencies (the higher frequency I have intensively worked in past is FM [View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-427f6777-9a77-4f12-840c-e6dd8638df1a/contentimage_5F00_1.png:16:16] ) what kind of transmissions are broadcast on these high frequencies? It seems the range between Mobile phones and other dedicated bands. Or I am totally wrong?
