QSO Mapper

Show Amatuer Radio QSOs on an interactive map and table.

There are two basic ways this web application is designed to be used:

  1. Uploading local ADIF files from a web browser for local display (default).
  2. Using the URL parameter to load a web-accessible ADIF file and possibly share your QSOs and map.

Both ways require you to get your own access token for the map provider you choose to use. The default map provider is OpenStreetMap which is open but prefers you get map tiles from a third-party like MapBox. If you fork (or clone) this repo for you own use, you should really get an API key from MapBox and change the mapTileFormat in qso-mapper.js to your access token.

The project stated using Google Maps but that fork has not been updated. The code is in google-map.js and commented out in index.html (for now). OpenStreetMap and Leflet are used in the current branch. These are both open products.

Uploading Local ADIF File(s)

This method is inteded to be used to view a log of contacts (QSOs) that you have on your computer in ADIF format. The application works in this mode by default.

Upload QSO Map Example

By using Select file... at the top-right of the application window you can upload a local ADIF file. The QSOs in the file will be loaded and shown on the interactive map as markers or Maidenhead (grid square) Locators. The Reset button will clear the markers so you can load a different file. You can load multiple files, just don't click Reset between each load and the new QSOs will be added to the current ones.

When using the application this way, the map is not directly sharable with others. To share the map you could send your ADIF file to someone else and they would upload and view the same way. However, a better way to share your QOS map is to use the second method below and not this one.

Using a URL to ADIF File(s)

This method allows you to show and share a log of your contacts. You upload your ADIF file to a website and then others can see the QSOs mapped directly, without uploading anything.

Shared QSO Map Example

The application loads a web-accessible ADIF file and displays it on the map. The file could be on another server or in the same location (or same repository) as the application code.

To use this mode of the application, simply supply a url parameter to the index page. The application will try to load the contents of the referenced URL as an ADIF file. If the loading succeeds, the QSO records from the file will be shown on the map.

When using this variant of the application, the Select file... and Reset are disabled and you are only able to load a single ADIF file URL.

You should consider forking the repository if you intend on using this long-term. That way you can change the map tile access token to your own token making sure it works for you long-term. If you don't fork and use your own, you run the risk of what I have here running out of quota and not working at all for you.

Mentions

I wanted to thank the Linux in the Ham Shack podcast folks, who picked up on my pushing to GitHub and mentioned the project in their Party Like it's 1499 episode. As an ex-scoutmaster for a Boy Scout troop, I think it would be an excellent idea to use QSO Mapper to show your Jamboree on the Air contacts!
