# QTH Locator
|
|

Convert your current GPS location to the [Maidenhead](https://en.wikipedia.org/wiki/Maidenhead_Locator_System) locator system used by HAM amateur radio operators.

|
A Maidenhead locator compresses latitude and longitude into a short string of characters, which is similar in concept to the World Geographic Reference System or GEOREF. This position information is presented in a limited level of precision to limit the number of characters needed for its transmission using voice, Morse code, or any other operating mode.

|
|
|
The chosen coding uses alternating pairs of letters and digits, like so:
