M0LTE.Ardop

A managed, ardopcf-compatible ARDOP 1 virtual TNC for .NET, extracted from the pdn-soundmodem packet-radio modem. It is, as far as we know, the only ARDOP TNC written in managed C#.

  • The full modem — 4FSK / 4PSK / 8PSK / 16QAM modulator and demodulator, Reed-Solomon FEC.
  • The full ARQ engine — connection setup, bandwidth negotiation, gearshift, teardown.
  • A byte-compatible ardopcf TCP host interface, so Winlink hosts (Pat, Winlink Express, ARIM, gARIM, hamChat) connect unmodified on the usual command/data socket pair.

Validated bidirectionally against ardopcf itself (byte-for-byte host transcript; audio decodes both ways; trial-identical noise-knee).

Install

dotnet add package M0LTE.Ardop

Run a TNC on an audio device

Implement the three M0LTE.Radio.Audio seams for your sound card / SDR (all at ARDOP's native 12 kHz), then:

using M0LTE.Ardop.Host;

IAudioInput  rx  = /* your 12 kHz capture  */;
IAudioOutput tx  = /* your 12 kHz playback */;
IPttControl  ptt = /* your keying          */;

await using ArdopHostServer server = ArdopHostServer.ForAudio(rx, tx, ptt, commandPort: 8515);
server.Start();
// Point Pat (or any ardopcf host) at localhost:8515 — data socket is 8516.

ForAudio pumps receive audio from rx into the demodulator, and each transmit burst keys ptt, plays through tx, drains, and unkeys. For full control, construct new ArdopHostTnc(...) yourself and bind its Transmitter / ProcessReceive seam directly.
