Radio de Galena Moderno - 1 (CIR1025S)

Written by: Newton C. Braga
Category: Banco de circuitos

 

Esta radio de galena moderna sustituye el cristal de galena por un diodo de germanio como el 1N34 o equivalente. Los capacitores de acoplamiento de antena son cerámicos y el auricular debe ser magnético de alta impedancia. En una alternativa moderna se puede utilizar una cápsula piezoeléctrica en paralelo con un resistor de 22 k. La bobina se puede enrollar con hilo 28 en un tubo de cartón con poco más de 1,2 cm de diámetro de modo que dentro de ella deslice un bastón de ferrita de 1 cm de diámetro. La impulsión de ese bastón es que hará la sintonía de las estaciones. La antena debe ser muy larga y es importante la conexión a tierra. Se utilizarán antenas de al menos 5 metros de longitud.
