Offline quick reference for Tri-Cities area ham and GMRS repeaters — frequencies, tones, and calls. Works offline after your first visit.
This is the field subset of the East Tennessee repeater book — searchable offline, filterable by band or call. The canonical full list, CHIRP CSV, and nets live on local.php; this tool is what you open in the rain.
KI4TQN maintains one verified dataset for the Tri-Cities, Erwin / Unicoi, and nearby SW Virginia. local.php is the full guide (repeaters, GMRS, DMR, nets, clubs, NOAA). The go-bag sheet is a one-page print. This tool is the same data in a filter box for the PWA.

Trustees take machines down, change PL, or lose linking. Treat this as a programming aid. Confirm with RepeaterBook, the club site, or a local net before you depend on it.
No. NETNRC (netrc423.org) is the linked repeater community. District 7 SKYWARN trains on those machines. ARES/RACES activation is a separate served-agency path — see east-tn-ares.php.
