Double click the gridcalc.exe executable or use your preferred method to start the software. Once the program is started, it will display a simple window waiting for your input:
The software will accept 1 to 6 -character grid locators. First enter your own locator in the My locator field and then the target locator in the DX locator field.
The software will recalculate the bearing and distance everytime a new character is entered. You can also enter space or question mark instead of a valid locator character. In this case the software will estimate the values to the midpoint of the possible values for the character. The same estimation happens if a locator has an odd number of characters. This may become handy when you're having problems copying the locator of the DX and are trying to turn your antenna towards it with partial locator information.
The calculated values will also automatically be recalculated as you type in more accurate locators with 4 or 6 characters:
DistanceMultiplier=1.0 AngleMultiplier=1.0As an example if you want to see the distances in miles and angles in grads, change these to:
DistanceMultiplier=0.621371 AngleMultiplier=1.111111In this case you probably also want to change the corresponding user interface texts in main.ini file to something like this:
Item5LBLEnglish=Dir. (grad): Item7LBLEnglish=Dist. (miles):
[GUIOptions] ; Select the user interface language by uncommenting the desired line. Language=English ;Language=FinnishYou can also create your own translation using the following procedure:
1) Comment out all the current languages in gridcalc.ini and add the name of the new language like this:
[GUIOptions] ; Select the user interface language by uncommenting the desired line. ;Language=English ;Language=Finnish Language=Klingon2) Make copies of all ItemXLBLEnglish items in main.ini file, change the name of the language to the one you defined above and then provide your own translations as is done for the first item below:
Item1LBLEnglish=My locator: Item1LBLFinnish=Oma lokaatt.: Item1LBLKlingon=wI' Daq
