A browser-based check-in logger for amateur radio nets. All data is stored locally in the browser — nothing is sent to a server. An optional QRZ XML subscription enables automatic callsign lookups to fill in operator name and location.

• Enter net name, date/time, frequency, and mode in the header bar
• Add check-ins by callsign; Tab performs a QRZ lookup without adding the station, Enter adds immediately
• Track traffic status per station (none / pending / covered) and whether each station has been called
• Log panel for recording notes per station; Process Next cycles through pending traffic and uncalled stations automatically
• Download the log as an ADIF file (.adi) for import into logging software, or Print / Save as PDF via the browser print dialog
• All data persists across page reloads via localStorage

net_checkin.html is a single self-contained file. It requires no build step and can be served by any static web server.

Add net_checkin.html to your Jekyll docs/ directory. The file includes Jekyll front matter and a {% include footer.html %} tag that will be processed normally during the site build.

Strip the Jekyll front matter and Liquid tags before deploying. The serve.js script in this repo does this automatically for local use:

node serve.js

Then open http://localhost:3000 in a browser. Bootstrap assets are loaded from the jsDelivr CDN; no local copies are needed.

Pre-process the file (remove front matter, replace {{ page.title }}, and remove {% include ... %} tags), then deploy the resulting HTML file as you would any other static asset.

Tests are written with Playwright and run inside a Docker container so nothing needs to be installed on the host system.

• Docker
• Make

make build

This builds a Docker image containing Node.js, the Playwright npm package, and the Chromium browser. The browser download is cached in Docker layers and only re-runs when package.json or package-lock.json changes.

make test

Tests run inside the container. When they finish (pass or fail) the path to the HTML report is printed:

Report: file:///path/to/net-checkin/playwright-report/index.html

Open that file in a browser to see the full results with failure details and screenshots.

A GitHub Actions workflow (.github/workflows/test.yml) builds the Docker image and runs the full suite on every push and pull request to main. The HTML report is uploaded as a build artifact and retained for 14 days.
