About RepeaterList

A clean, fast browser for the worldwide amateur radio repeater directory published by hearham.com.

What it does

The full dataset (~22,000 repeaters) is imported into a local database and served as a searchable map and table. Filter by mode, band, country, city, state, access tone, frequency, backup/emergency power, or distance from your location, and open any repeater for full detail.

Live status

For AllStarLink nodes, RepeaterList shows live status pulled from the AllStarLink network — a green dot when the node is online, and a pulsing red ● live when someone is keyed up right now. (The community's #1 frustration with repeater directories is dead listings — so we show what's actually alive.)

Program your radio

Export any filtered set as a CHIRP file (the free, universal radio programmer) and load it straight into your HT. Dual-mode (DMR/FM) repeaters export as usable FM channels rather than being dropped, so analog radios get the analog side.

How the data is cleaned

The source data is free-text and inconsistent, so every record is normalized on import:

Mode — trimmed, de-cased, and split into canonical modes (FM, DMR, D-STAR, YSF, P25, NXDN, M17, …). Multi-mode repeaters like P25/YSF/D-STAR/DMR are parsed into their components and classified Analog / Digital / Mixed / Data / ATV.
Access tone — correctly typed as CTCSS (Hz), DCS, DMR Color Code, or NXDN RAN, rather than lumping everything together.
Country — derived from the repeater's coordinates by point-in-polygon against world borders, which is far more reliable than parsing the free-text city field.
Band is derived from frequency, duplicate records are removed, and invalid coordinates/frequencies are flagged.
