How to use SA5IKN QRB Calculator

Enter two Maidenhead locators in the fields above. Valid locator lengths are from 4 to 10 characters.

• Blue marker: Your QTH locator
• Green marker: DX station locator

Once both locators are entered, the map will show the azimuth, distance, and a line connecting the two markers.

You can also drag either marker directly on the map. The corresponding locator input will update to a 10-character locator.
