cats-sdr-igate

This is a CATS RX-only I-Gate which can use a cheap SDR receiver to decode CATS packets. It prints them to the terminal and optionally forwards them to FELINET. Out of the box, it works with the RTL-SDR.

Debian & Derivatives (Ubuntu, Raspbian, etc.)

Building

To build the software, you will need to install Rustup. You'll also need git. After these are installed, restart your terminal, or open a new one. Then run these commands:

sudo apt install rtl-sdr
cargo install cargo-deb

git clone https://gitlab.scd31.com/cats/sdr-igate
cd sdr-igate
git pull
cargo deb

The resulting deb package will placed in target/debian/cats-sdr-igate_VERSION.deb

Installing

Once built, the package can be installed with sudo dpkg -i target/debian/cats-sdr-igate_VERSION.deb, replacing VERSION with whatever version and architecture was built.

Configuring

The configuration for the I-Gate lives in /etc/cats-sdr-igate/config.toml. Make sure to update this before using the utility - most importantly, the callsign must be configured. Optionally, you can remove the entire [felinet] section if you don't want to forward packets to the network.

Running

Start the service with sudo systemctl start cats-sdr-igate. If you want it to start automatically at boot, you can run sudo systemclt enable cats-sdr-igate.

cargo build --release

Configuring

Copy the config.example.toml file to config.toml. You can either keep it in the current directory or move it to /etc/cats-sdr-igate/. Modify this file - be sure to add your callsign, or remove the [felinet] section if you don't want to forward packets to the network.

Running

Make sure you have rtl-sdr installed. As a sanity check, verify the rtl_fm command exists.
