Satelit AO-109 bol uvoľnený pre amateur radio využitie! Lineárny transpondér má Uplink na 145,860 MHz – 145,890 MHz a Downlink na 435,760 MHz – 435,790 MHz. maják by mal pracovať na 435,750 MHz, , pričom jeho hlavnou úlohou bolo testovanie vplyvu radiácie na elektronické súčiastky a podporiť amatérske satelitné spojenia.
