Description

(Siehe auch deutsche Beschreibung)

Above this text is a small java-applet for hams that allows

• converting a QTH-locator to north latitude/east longitude and vice verse.
  If you type a locator into the field "Locator" and press <enter> the fields "North" and "East" are calculated.
  If you type a number into either field "North" or "East" and press <enter> the field "Locator" is calculated.
• converting the old european QTH-locator to the current format.
  If you type an old european locator into the field "Locator" and press <enter> the value will be converted to the new format.
  (e.g. "EN74C" will be converted to "JO43IB")
• to calculate the distance and the (antenna-)direction between two locations on the earth.
  Just enter values for "Your Location" and for "Other Location" and press <enter>. Distance and direction will be displayed in the message area.
• showing the locator in a geographic map
  Every time you enter a location into the form, the location is shown in the map, too. "Your Location" appears in blue, "Other Location" in red.
• entering qth-locators with mouse clicks in the map
  While you are moving the mouse over the map you will see the current mouse position as qth-locator and the distance to your location in the browser's statusline.
  By mouse-clicking in the map you set the "Other Location" field in the form.
  If you drag the mouse, the drag-start will become the "Your Location" field and the drag-end (where you release the mouse button) sets "Other Location" of the form.
