Ar trebui sa scrie pe el, desi nu stiu cat te-ar ajuta aceasta informatie.

Ai un receptor cu amplificare directa, nu superheterodina, conceput pentru pionierii din epoca sovietica, copii care activau, sau nu, in cercuri tehnico-aplicative si care-si descopereau pasiunea in domeniul radio in particular, ca o potita de intrare in domeniul electronicii in general.

Posibil ca acest condensator variabil sa fie de fapt un trimmer ceramic (este de tipul disc) de capacitate mare (parca pana in 200pF), similar celor din Electron M, Zvezdochka sau altele similare. Daca este asa, atunci se invarte rotita de acord continuu, nu doar un sector de cerc (mai putin de 360 grade).

In Bucuresti trebuie sa receptionezi sigur pe UM Romania Actualitati pe 855kHz (emitatorul este in Tancabesti si are 400kW) si Antena Satelor pe 603kHz (emitator Herastrau-pod Chitila si are 30kW). Pe UL ar trebui sa receptionezi Antena Satelor pe 153 kHz de la Bod, dar doar functie de unde stai (bloc-casa curte) si gradul de poluare electromagnetica si poate ca trebuie sa pui aparatul la geam.
