## Overview

The Maidenhead Locator Encoder is a precise utility designed to convert geographic latitude and longitude coordinates into the Maidenhead Locator System (QTH locator) used extensively in amateur radio and global positioning.

## Inputs

- **Latitude** (number): Enter latitude (-90 to 90)
- **Longitude** (number): Enter longitude (-180 to 180)
- **Precision** (select)

## When to use

- Determining your grid square for amateur radio contest exchanges.
- Calculating precise location identifiers for VHF/UHF propagation mapping.
- Standardizing geographic data into the Maidenhead format for logging software.

## How it works

- Enter your current latitude and longitude coordinates into the input fields.
- Select your desired precision level, ranging from 2-pair (Field/Square) to 4-pair (Extended) grids.
- Click the encode button to generate the corresponding Maidenhead locator string instantly.

## Use cases

- Amateur radio operators logging contacts during field day events.
- DXpedition planners identifying specific grid squares for signal propagation.
- Geocaching enthusiasts converting GPS coordinates to grid-based formats.

## Frequently asked questions

### What is a Maidenhead locator?

It is a grid-based system used by radio amateurs to concisely describe a geographic location on Earth.

### How does precision affect the output?

Higher precision adds more character pairs to the locator string, narrowing down the geographic area from a large field to a very small square.

### Can I use negative numbers for coordinates?

Yes, use negative values for Southern latitudes and Western longitudes.

### Is this tool suitable for mobile use?

Yes, the interface is responsive and works on any device with a web browser.

### What is the difference between 2, 3, and 4 pairs?

2 pairs represent a large grid square, 3 pairs represent a subsquare, and 4 pairs provide high-resolution extended grid data.
