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>

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
