Early Preview: ProtoSDR – a Client for Linux

I’d like to share an early look at ProtoSDR, a SmartSDR-style client application designed to run natively on Linux.

At this stage, ProtoSDR already supports a solid set of features:

  • Multiple panadapters and slices
  • multiFlex operation
  • LAN discovery and WAN (SmartLink) connections
  • Receive audio
  • Band, antenna, and mode selection
  • DSP filter selection and adjustable filter width
  • Split operation
  • Audio controls
  • X/RIT

This is still an early build, and needs a lot of work, but its quite functional.

    This is fantastic Simon! It feels like we just started discussing SmartSDR for Linux, and you already have a working version!

    Tuning and moving the panadapter look very smooth - nicely done! It feels like the hard part is done, now it is the million little things that SmartSDR does that has to be accommodated.

    The Linux community will be thrilled to see this!

    This week I focused on incorporating the v4.1.3 changes and adding UI components to the client application. In the video, you can see I click the Tune button and the RF Power Meter is working. Then I demonstrate the various menus.

    This is running on Ubuntu with Gnome, which I figured was a pretty popular distro to test with. I'm writing code that will compile on Linux x86, Windows and Raspberry Pi (Arm). I've run it on all platforms - Windows and Linux are fine, but it seemed like there was an audio lag on an Rpi4. Perhaps an RPi5 would do better - but Linux x86 is my main focus.

    You don't realize just how many UI components there are and how they interact until you start to have to replicate them all. For the most part, I'm creating a UI where most controls are in the same place as SmartSDR for Windows.

    While I thought I had the Panadapter and Slice Flag side-to-side scrolling working correctly, a close comparison with SmartSDR behavior revealed I needed to rework it. I think I've got it working identically now.

    Thank you to the many people who have offered to be a tester. I'm not at that point yet, but will keep the offers in mind.

    As you can see there's still a lot more UI work remaining.
