This tool downloads the current JCC / JCG / Ku data from the JARL website and outputs a CSV file containing all of the primary and secondary administrative regions for use in amateur radio applications.
You can download the most recent CSV file here: jcc.csv
The easiest way to run this application is like this:
cargo run --release > jcc.csv
You can also build the application without running it like this:
cargo build --release
This places the binary at target/release/jcc.
