About this app

TA73, Türkiye's amateur radio relay guide. Need a local relay, wondering which band a distant station is on, or just want a ready-to-use radio toolkit? All in one app, free.

Türkiye'S RELAYS, ON ONE SCREEN
Over 500 relays in 81 provinces, neatly listed by region and province. Frequency, offset, CTCSS tone, mode, power, altitude, and location information for each relay on a single card. You can instantly search by call sign, province, or frequency; filter by FM, DMR, D-STAR, C4FM, APRS, EchoLink, ATV, SSB, and cross-band modes, or by band.

The most useful feature in the field is "Relays near me": you see the relays closest to your location in order of distance. Add your favorite relays to your favorites and share them with your friends with a single touch.
