A simple demo using SparkSDR's websocket interface.
make build # builds wasm/js files and places them in `static/` dir
make db # optional - us callsign json files (need 6GB of free storage)
make serve # runs a small web server on port 8000 serving the files in `static/`
Make sure web sockets are enabled in SparkSDR and then load http://localhost:8000 in your browser.
Running make db will download current FCC and LoTW records to create a collection of json files for each US callsign. This will consume a large amount of storage space (just under 6GB). Will place the generated json files in static/out.
make clean will remove any fcc/lotw downloads and any temporary files generated during the process. This will not remove the json files.
