Receptor de Ondas Medias (CIR8701S)

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

 

Este simple receptor de ondas medias fue encontrado en una revista Técnica Práctica de Italia del año 1965. El proyecto es aún actual si cambiamos TR1 y TR2 por un BC558. El transformador de salida se obtiene de una radio transistorizada fuera de uso. La bobina está formada por 75 espiras de hilo 28 en un tubo de 2 cm de diámetro. Las formadas se hacen de 15 en 15 espiras. La antena debe ser larga y la conexión a tierra es importante. C1 puede obtenerse en una radio AM fuera de uso. El circuito admite varias mejoras. Una de ellas consiste en conectar de L1 / C1 Pa tierra un resistor de 47k en paralelo con un capacitor de 100 nF.
