One of the most useful tools for amateur radio operators is the ability to quickly calculate the distance and bearing between two stations. Whether you’re chasing DX, planning an antenna setup, or logging contacts, having accurate information at your fingertips makes a big difference.

Thanks to E25VBE, there’s now a powerful and easy-to-use web-based tool: DADA 1.8 – Ham Radio Distance and Bearing Calculator.

Key Features

• Worldwide Location Search
  No more manual coordinate lookups! With OpenStreetMap integration, you can simply type in a location name like KLCC, Penang, Hokkaido, or MIT and the tool will instantly find it.
• Maidenhead Grid Support
  Perfect for hams who work with grid locators. Just enter a Maidenhead square (like OJ02vx or OI33tb) and the calculator does the rest.
• Distance & Bearing Calculator
  Get precise measurements of distance in kilometers and bearing in degrees from your home QTH to the target station.
• Real-Time Logging
  Each action is logged so you can keep track of your searches and results.

Example in Action

Let’s say your home QTH is Kajang, Selangor, Malaysia (OJ02vx) and you want to work a station in Bandung, Indonesia (OI33tb).

• Distance: 1277.82 km
• Bearing: 150° (Compass reference: N=0°, E=90°, S=180°, W=270°)

In just a few clicks, the calculator gives you all the information you need for pointing your antenna or logging the QSO.

Why This Matters for Hams

This project brings convenience and accuracy to everyday amateur radio operation. Whether you’re a casual operator or a DX hunter, DADA 1.8 makes it simple to:

• Check propagation paths.
• Align antennas correctly.
• Log accurate QSO details.
• Explore worldwide locations with ease.

Final Thoughts

Congratulations to E25VBE for this excellent contribution to the ham radio community. Tools like this make our hobby more enjoyable and accessible for operators everywhere.

If you’re looking for a reliable and user-friendly distance and bearing calculator, be sure to give DADA 1.8 a try.
