Yana haɗa tsarin sitiriyo, daidaitawar FM, da haɓaka mitar rediyo akan guntu ɗaya; yana buƙatar ƴan sassa na gefe;
Rabuwar tashoshi biyu yana da girma, tare da ƙima na 45dB;
Matsakaicin shigarwa shine 540Ω (fin = 1kHz), kuma shigar da shigar shine 37dB (Vin = 0.5mV);
RF fitarwa iya isa 600mV.
Da'irar tana amfani da zane mai kyan gani, kuma ana ƙara ƙarar ƙarawa zuwa abubuwan fitarwa a baya don biyan buƙatun wutar lantarki. Ya kamata a kula a nan a cikin da'irar watsawa don kada a sami ƙarfi da yawa. Ba bisa ka'ida ba idan ya yi girma da yawa kuma yana shafar wasu mitoci. Babban iko doka ne kawai a wasu makada na mitar.
