Which Digital Interface for You?

  • A black metal electronic device labeled 'NA6D OpenTNC' sits on a bright blue surface, with a blurred background showing other electronic equipment.

    OpenTNC

    The reliable hardware TNC for packet radio.

    How It Works: Dedicated hardware handles AX.25 encoding/decoding on-board via true KISS mode. Zero OS audio headaches or calibration.

    Ideal Use: Mobile rigs, base stations, 24/7 APRS digipeaters/iGates, Winlink packet gateways, and EmComm deployment boxes.

    Choose this if you want rock-solid packet performance, standard DE9 Kantronics-compatible cabling, and direct Mini-DIN6 data port integration.

  • AIOC

    The pocket-sized interface for handheld radios.

    How It Works: Combines a USB sound card and serial PTT cable into a compact dongle that plugs straight into your HT's 2-pin K1 port.

    Ideal Use: CHIRP radio programming, AllStarLink micro-nodes, and soundcard-based packet/VARA on the go.

    Choose this if you want an inexpensive, minimalist adapter to run digital modes directly from your HT.

    Starting at $20 (Kit) / $33 (Assembled)
