Brief Comparison of TNCs (2014)


  • I recommend this TNC
    • relatively inexpensive
    • only has kissmode, no command mode
    • easy to set up
    • Can be powered from a USB port
    • Similar design to the TNC-Pi for the Raspberry PI

Kantronics KPC3+

  • Works well but has a buffer wrap bug in firmware that Kantronics has not acknowledged (as of 1/20/2014)
  • Expensive, compared to other 1200 baud TNCs.
  • Has many modes of operation including command, KISS, PBBS, KA-Node, Slave mode
  • Requires a 12 V power source

Byonics TinyTrak 4

  • I spent some time vetting this TNC because I like it a lot but it drops back to back packets in the same test that TNC-X & KPC3+ do not.
    • Many HAMS claim this TNC works well as a Winlink TNC … but I'm not one of them.
    • Good APRS TNC

Argent Data OpenTracker

  • I do not own this TNC but based on this link I do not believe it will handle connection oriented protocols like B2F.
    • It has a good rep as an APRS TNC.
