What This Tool Does
This is a fast callsign lookup tool designed specifically to help Net Controllers and radio operators quickly identify and keep track of stations checking into amateur radio nets. When someone calls in with their callsign, you can instantly look up their details and maintain an accurate record of net participants.
What makes this better than other apps?
- Speed: Instant lookups with minimal delay - its REALLY fast
- Simplicity: Clean, distraction-free interface
- Ad-Free: No ads or pop-ups to interfere with usage
- Lightweight: Fast loading times even on slower connections
- Mobile Friendly: Works well on both IOS and Android
Why It Was Created
The Problem
As a radio operator, I found myself constantly needing to quickly look up callsigns during nets to:
- Verify station details and locations
- Keep accurate records of net participants
- Properly identify stations for introductions
- Maintain net control standards
The Solution
I developed this tool to provide instant access to QRZ.com data without the need to navigate through multiple pages or deal with ads and distractions. Just enter a callsign and get the essential information immediately.
Technical Implementation
- Hosting: Netlify with continuous deployment. Cloudflare DNS, CDN, Protection and monitoring.
- Frontend: Modern HTML5, CSS3, and JavaScript
- Backend: Netlify Functions (serverless)
- API Integration: QRZ.com XML Data Service
- Data Source: Live QRZ.com database via XML subscription
Privacy & Data
The tool respects amateur radio operator privacy by:
- Not displaying street addresses or postal codes
- Only showing publicly available QRZ.com information
- Logging lookup activity for net control purposes only
- Operating with read-only access to QRZ.com
Displayed Information
The tool shows only essential information needed for operator lookups:
- Name: Operator's first name, it also displays nickname if applicable
- Country: General location (country level)
- Grid Square: For distance/direction calculations
- License Class: Current license level
- Expiration Date: When license expires
- Website: If available
- Additional Info: Only works if the operator has entered this new field in qrz.com
If the data isn't in the qrz.com database it shows nothing at all, this is to keep the app responsive
Perfect for all Radio Amateurs
Whether you're running a local repeater net, an HF net, or emergency communications, or just want to keep track of callsigns, this tool helps you:
- Quickly identify check-ins by name and location
- Maintain professional net control procedures
- Keep accurate records of participating stations
- Introduce stations properly to the group
- Verify callsigns and license status
