Upload your ADIF log file and visualize your contacts on an interactive map. See where your signal reached, color-coded by band, with multiple map styles and high-resolution export for sharing and printing.

🗺️Five basemap styles

Esri Street, Topographic, National Geographic, OpenStreetMap, and CartoDB Positron, switchable at any time.

🎨Color-coded by band

Pins and arcs colored per band, with one-click filtering above the map.

⚡Animated contact arcs

Watch curved great-circle paths draw from your activator to each QSO in order, at Slow, Medium, or Fast.

📍Smart clustering

Dense areas group into numbered clusters that break apart as you zoom in. Toggle on or off at any time.

📊Map Summary stats

Activation start and end times, QSOs per hour, and band breakdowns calculated automatically from your log.

💾High-resolution export

Save your framed map as PNG to share, or as KML to open in Google Earth Web.

🔒Private by design

Your log is processed in memory only and discarded immediately. No account, no tracking.

How it works: Select your .adif or .adi file below, optionally enter your callsign and grid square, and click Upload. The mapper will plot every contact on the map using the best available location data from your log. No data is stored on our servers.

📋 Designed for individual POTA activations and contest logs. Maximum 2,500 QSOs per upload.

📡 How contacts are placed: each contact is mapped from the most specific location in its log entry. Coordinates, a grid square, or a POTA park reference place it exactly. A state or section places it at that operating area. A contact that carries only a callsign is looked up, which returns the operator's registered home location, where they are licensed rather than where they were on the air. The Help Guide above explains how to get the most accurate map.

Tips for Best Results

Upload your log straight from your logger. You don’t need to pre-process it, and you should skip any QRZ or callsign sync. The mapper looks up home locations itself from official FCC and ISED license data, so pre-filling grids adds nothing and can work against you: a sync overwrites the section a portable station sent with the operator’s home, which moves them off where they actually were. A raw log keeps each contact’s state or section exchange, the truthful operating location, and the mapper places the rest.

Enter your grid square. This places a special activator pin on the map showing your operating location. For POTA, Field Day, and any portable operation, enter the grid square for where you’re actually operating, not your home grid.

Zoom and explore. Areas with many contacts are grouped into clusters showing the count. Click a cluster or zoom in to see individual pins. Click any pin for details about that contact.
