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. Amateur radio licence required to transmit. Kerchunk is a directory; it does not transmit.
