Callsign Checker

An app for checking the format of a callsign and finding the country it belongs to.

Downloading the country database

Data about countries can be downloaded from either Amateur Radio Country Files by AD1C or Clublog.

Obtaining the AD1C country database

Download any cty.dat file from the Country Files website. I recommend using the Big CTY file. Instead of cty.dat you can also use the cty.csv file.

Parsing of cty.dat or cty.csv can be done with the script cty-parser.ts.

Note: The cty.dat does not contain the adif DXCC number.

Obtaining the Clublog prefix database OBSOLETE

Read how to obtain the Clublog prefix file here

Parsing can be done with the script clublog-parser.ts.

Deploying the app

The app can be deployed using the following command:

yarn install
yarn build

Deploy the contents of the build directory to your server.
