Se pot modifica unele de fapt cele analogice usor sa cobori banda mai jos de 88MHz.

Banda est este 65 - 73 MHz. 76 MHz este intr-un canal TV. Se poate cobori banda 88 - 108 la 76 - 100 prin comprimarea spirelor bobinei oscilatorului sau, mai putin recomandabil, prin adaugarea unui mic condensator paralel cu variabilul.

Prin comprimare mai greu eu scoteam 2-3 spire din ele.

Cu spire mai putine scade inductivitatea si creste frecventa. Adica iasa exact pe dos fata de ceea ce se cere.

cauta un player auto facut pentru piata japoneza. ar trebui sa-ti rezolve problema deoarece lucreaza in banda FM 76.1-89.9 MHz

cateva exemple: (pioneer) carrozzeria, (clarion) addzest.
