Kerchunk

Kerchunk is a repeater directory for amateur radio operators. Find the repeaters around you on a map, see everything you need to work them, and plan which ones you'll pass on a drive — with the whole directory kept on your phone so it works where there's no signal.

Buy it once. No subscription.

MAP
• Every repeater around you, drawn where it actually is
• Filter by band and mode: FM, DMR, D-STAR, Fusion, NXDN
• Tap any repeater for the full details
• Sort by distance, so the nearest is the first thing you see

WHAT YOU NEED TO WORK IT
• Output and input frequency, and the offset
• Uplink and downlink tones, so you can set both squelch and access
• Modes, band, access type and operational status
• Location, grid square, city, county and state

TRIP PLANNER
• Set a start, an end and any stops in between
• See the repeaters along your route, not just the ones near its ends
• Pick the ones you want and keep them with the trip
• Save trips and edit them later

OFFLINE
• The directory lives on your phone, not just in the cloud
• Search and map work with no signal — which is when you need a repeater most
• Syncs changes when you're back online

KEEP IT ACCURATE
• Submit a repeater that's missing
• Correct one that's wrong
• Confirm the ones you've actually worked, so other operators know the entry is current

Kerchunk reads the OpenAPRS repeater directory, and everything you contribute goes back into it.
