FreeDV-JATE

FreeDV- Just Another TNC Experiment

My first attempt to learn more about FreeDV and how to create a TNC which gets data from a TCP/IP socket

Credits

David Rowe and the FreeDV team for developing the modem and libraries FreeDV Codec 2 : https://github.com/drowe67/codec2

This software has been heavily inspired by https://github.com/xssfox/freedv-tnc/

Setup

Install FreeDV-Socket-TNC directly to home folder and compile codec2 automatically

sudo apt install portaudio19-dev build-essential cmake
wget https://raw.githubusercontent.com/DJ2LS/FreeDV-Socket-TNC/dev/install_socket_tnc.sh -O ~/install_socket_tnc.sh
chmod +x ~/install_socket_tnc.sh
./install_socket_tnc.sh

Usage main program

./main.py --port 3000 --tx 1 --rx 1

Usage testclient

./socketclient.py --port 3000 --data "BC: hello"

Socket Commands

Send a simple broadcast

BC:<DATA>

Send an ARQ like frame which will ask the receiver for acknowledgement

ACK:<DATA>

Other stuff

Audio sinkhole

Send real audio without external devices or sound cards

sudo modprobe snd-aloop index=1,2 enable=1,1 pcm_substreams=1,1 id=CHAT1,CHAT2

TNC 1

./main.py --port 3000 --tx 1 --rx 1

TNC 2

./main.py --port 3001 --tx 2 --rx 2
