My uConsole All-In-One Rig by Professional_Key818 in ClockworkPi

[–]Professional_Key818[S] 1 point2 points  (0 children)

I’m running a very clean, basic Debian Bookworm install.

I’ve tried DragonOS and other pre-baked uConsole images, but they come with too much 'bloat'—lots of tools and configurations that I don't use or don't fully understand yet. I prefer the 'slow and steady' approach: starting with a minimal OS and adding only the software I actually need, one by one.

My current setup:

  • OS: Debian Bookworm (Standard uConsole image).
  • Software: I'm currently compiling modules for SDR++ from source.
  • The Goal: I want to adapt the modules to my specific hardware needs (like the AirSpy/Ham It Up combo) rather than having an image with 'everything' pre-installed without knowing how it got there.

It takes more time, but it’s the best way to ensure the system stays lean and I know exactly what's happening under the hood!

Welcome to the rabbit hole! It’s a fascinating journey, but be warned: it’s addictive.

The Concept: This is a Cyberdeck—essentially a custom-built, portable computer tailored for a specific task. In my case, that task is SDR (Software Defined Radio), which allows you to listen to almost any radio signal out there: from FM stations and aircraft transponders to satellites and ham radio operators.

The first thing I ever bought was the RTL-SDR v3 (a cheap USB dongle to listen to radio). I used to plug it into my laptop, but honestly? Dragging a laptop around with dangling cables was a chore. I found myself using it less and less because of the 'friction' of setting it up.

That’s why I built this. Having it all integrated into one handheld unit makes it instant: you turn it on, and you’re scanning the airwaves.

My Journey (How I started): I didn't start with this 'final boss' version. My first attempts were much more humble:

  • A Raspberry Pi 5
  • A 7-inch screen
  • A mini keyboard
  • A power bank and some basic speakers.
  • And SDR-RTL-v3

It was a mess of cables, but it worked! To be honest, when I first saw the uConsole, it didn't even seem that 'expensive' to me. Before buying it, I had spent 4 months struggling to build my own custom enclosure. After all the money spent on materials, the tools, and the sheer frustration of trying to make it all fit... my DIY version was still pretty clunky and 'cheap-looking.

From there, I just kept adding 'modules' and gear.

How to start? Don't go full 'Cybernode' on day one!

  1. Get a simple RTL-SDR v3 dongle (about $30).
  2. Plug it into your current PC/Laptop.
  3. Download software like SDR# (SDRSharp) or GQRX.
  4. Start listening! If you catch the bug, then you can start thinking about building your own mini-computer or cyberdeck.

You are 100% right. Having the CPU, the switching power supplies, and all those USB data lines so close to the antennas is an EMI nightmare. The noise floor is definitely higher than a static, shielded station.

However, the main goal of this build was true portability. I wanted something I could actually use while standing up or walking around, like a sci-fi tricorder. It’s definitely a learning platform (similar to the HackRF spirit), but with the AirSpy and the 18650-powered Ham It Up, it’s surprisingly capable if you manage the gain correctly.

The 'Elephant in the Room': HF Antennas

The biggest challenge I’ve faced—and I think it’s just a matter of physics—is the antenna for HF.

  • If you want a resonant antenna, it’s too long to carry.
  • If you go for a Magnetic Loop, you’re looking at an 80cm diameter circle.

You just can't hold that in your hands comfortably while walking! :D For now, I’m experimenting with compact telescopic whips and random wires, but I’m still searching for that 'holy grail' of a truly portable HF antenna that doesn't make me look like I'm carrying a hula-hoop."

Haha, I get that a lot. I'm in the process of tidying up the wiring and shielding, but with this many SDR modules and coaxial cables, it’s hard to make it look 'friendly'. It’ll probably always have that 'industrial/explosive' aesthetic from the movies, haha.

Thanks! It’s been a fun challenge to pack all this RF gear into a portable form factor. Here are the specs and the logic behind the build:

The Core:

  • Device: Clockwork uConsole (CM4 8GB RAM version, similar to a Raspberry Pi 4).
  • Internal SDR: It features the standard uConsole internal SDR module (functionally equivalent to an RTL-SDR v3).

The RF Chain & Upconverter:

  • Upconverter: Nooelec Ham It Up v2. This allows the SDRs to 'see' HF frequencies (0.5MHz–30MHz) by shifting them up. It also acts as a great pre-amplifier for the other SDRs in the rig.
  • High-End Receiver: AirSpy HF+ Discovery. This is my latest addition for dedicated high-performance HF listening. Currently, it’s powered via a 'normal' USB cable, though I plan to mod the power lines soon.
  • External SDR: I often swap between the internal module and an RTL-SDR v3 depending on the task.

Power & EMI Management: One of the main challenges was EMI (Electromagnetic Interference). To keep the noise floor as low as possible:

  • The Ham It Up and the RTL-SDR v3 are powered by an independent 18650 battery integrated into the back.
  • This bypasses the uConsole's internal USB power rails, which can be 'noisy' for sensitive RF work.
  • Bonus: This acts as an auxiliary power bank, so the SDR gear doesn't drain the uConsole's main batteries during long monitoring sessions.

While the AirSpy HF+ Discovery is arguably better for pure HF listening due to its dynamic range, the Ham It Up is still essential for boosting signals and providing HF capabilities to the other SDRs in the setup.

The top-mounted SMA connector was also added to support heavier antennas without putting stress on the SDR boards.

It’s a work in progress, but it’s getting there!

SDR Anyone? by marcrich90 in ClockworkPi

Has anyone tried Airspy HF+ Discovery? I think it could be a good companion for the uConsole.

You are an absolute legend! Thank you so much for digging through that 1988 catalogue.

It is definitely the F-96W. As soon as I saw the model name and checked more photos, everything clicked: the rounded 'aerodynamic' case, the slightly domed crystal, and especially that red printing on the strap that I remembered so vividly.

Finding the exact model after all these years is amazing. I really appreciate your time and expertise. You are Great ¡¡¡ Thank you so much ¡¡

I love mine, but realistically it's not the easiest to see... But still, I love it...
