YouTube Talk: Evaluating 9 of the Best Single Board Computers for Ham Radio SDR Systems

Over on YouTube the Ham Radio 2.0 channel has recently uploaded a talk that Scotty Cowling (WA2DFI) did at the 2018 TAPR digital communications conference. His talk centers around single board computers and his findings on the nine best single board computers (SBC) for ham radio SDR setups.

Scotty's talk begins by discussing why you'd want to use SBCs in your ham radio SDR setup, and explains why you might want to place them with the SDR close to the antenna, and then distribute the data over ethernet cable. He then reviews 9 boards listed below: 

  • Hardkernel Odroid C1
  • Raspberry Pi 3B
  • Hardkernel Odroid XU4
  • ASUS Tinker S
  • FriendlyElec NanoPC-T4
  • Pine64 RockPro64
  • 96 Boards Mediatek X20
  • 96 Boards HiKey 960
  • UDOO X86 Ultra

The boards are compared against CPU clock speeds, architecture, cache, debut year, RAM, boot ROM, bus speeds, OS support, and more. Scotty also discusses the need for low latency operation, but is yet to compare this on the boards. The best value for money boards that Scotty recommends end up being the Odroid XU4, Tinkerboard, NanoPC-T4 and the RockPro64.

      Odroid XU4, according to the article, and then ASUS Tinkerboard S

      I own Odroid HC1 (which is equally powerful, but cheaper and “headless” version of XU4), and ASUS Tinkerboard (not S). Love them both, they are powerful and as easy to setup as Raspberry Pi (many of which I own too).

    There is one more interesting option: Odroid HC1
    It’s almost the same thing as XU4, so it’s a powerful beast, but it has no HDMI socket, and it’s built on a huge heat sink that works as a housing for the board and HDD or SDD that you can connect right to the board.
    It means that you can connect HDD or SDD and log a ton of data coming from RF.
    It has a very fast Gigabit Ethernet so it would also not be a problem to download the data from it.
    Armbian works great on it.

    There is however an important parameter in single board computers: required power supply. If you want the computer to be portable I highly recommend getting one with Mini/Micro USB socket for power, then you can power it from a good power bank no problem. I don’t think it’s possible with Odroids.
