  1. Protokollstack

    1. Applikationsskiktet (tjänster)

      1. Enkla textmeddelanden (Netcat, APRS, Meshtastic, MeshCore, etc)
      2. Mer komplexa tjatt-tjänster (typ irc ... matrix)
      3. TMS-TUI-Client
      4. epost/winlink, tex med pat

    2. Nätverksskiktet

      1. Kissattach
      2. FLDigi-Kissattach
      3. tncattach
      4. APRS digipeating WIDE paths
      5. LoRaMesh (Meshtastic, Meshcore,...)

    3. Länkskiktet

      1. AX.25 (HDLC-baserat)
      2. FX.25 (AX.25 med FEC)
      3. ARDOP (alternativ till FX.25)
      4. IL2P (Ethernetbaserat alternativ till FX.25)
      5. CW, MFSK, RTTY, Hell, DominoEX, Olivia, Throb
      6. VARA
      7. ASK, FSK, PSK, QAM
      8. FT8

  2. Modem

    1. Mjukvarumodem

      1. qtsoundmodem (stöder AX.25 FX.25, ARDOP och IL2P

      2. direwolf (stöder AX.25, FX.25 och IL2P)

      3. fldigi

        4. Stöder CW, PSK, MFSK, RTTY, Hell, DominoEX, Olivia, Throb. It can help calibrate a sound card to a time signal and do frequency measurement tests.

      4. js8call (stöder FT8)

        5. JS8Call är ett komplett meddelande- och nätverksprotokoll för tangent-till-tangent-chatt i realtid via kortvåg (HF). JS8Call-Improved is a community-driven evolution of JS8Call, bringing modern features, active development, and long-term support to HF digital communication. It’s fully compatible with existing JS8Call versions while adding new capabilities and refinements.

    2. Hardware TNC-modems

      1. Radio+ninoTNC

    3. Ljudkort+mjukvarumodem

      1. ISAAC
      2. https://digirig.net/product/digirig-mobile/

  3. SDR/USB systems

    1. SDR Hardware

      1. RTL-SDR-sticka som iGate

        2. Använder rtl_fm för demodulering av fm-signalen från stickan till audio som sedan skickas vidare till direwolf iGate.

      2. LimeSDR

    2. SDR Software

      1. sdrangel
        While SDRangel supports a wide variety of digital protocols (such as AX.25 Packet, APRS, D-STAR, and DMR), it is missing the specific DSP routines needed to decode the error-correcting IL2P (Improved Layer 2 Protocol) commonly used in amateur radio. For IL2P decoding, enthusiasts typically rely on dedicated software like DireWolf, which can process audio/IQ streams piped from SDRangel or other SDR front-ends.
