## 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
|
||||
|
||||
## Preview

|
|||
|
||||
|
||||
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 python3-pyaudio build-essential cmake
|
||||
python3 -m pip install crcengine ( if stuck in installing, run as superuser - sudo )
|
||||
sudo adduser $USER dialout
|
||||
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
|
||||
```
|
||||
## List audio interfaces
|
||||
```
|
||||
cd ~/FreeDV-JATE
|
||||
python3 tools/list_audio_devices.py
|
||||
```
|
||||
|
||||
## Usage main program
|
||||
```
|
||||
python3 main.py --rx 1 --tx 1 --deviceport /dev/ttyUSB0 --deviceid 311
|
||||
```
|
||||
|
||||
## Usage GUI
|
||||
```
|
||||
cd tools/tnc_gui
|
||||
python3 tnc_gui.py
|
||||
```
