Retransmisión AM (V072S)

Written by: Newton C. Braga
Category: Mundo de las válvula

 

El circuito que presentamos fue obtenido en una documentación de 1965, consistente en un pequeño transmisor de AM para la banda de ondas medias, con un alcance que llega a algunas decenas de metros.

La frecuencia es determinada por las dos bobinas que básicamente poseen 100 espiras de hilo 28 en un bastón de ferrita. En el proyecto original se utiliza una bobina comercial que difícilmente puede obtenerse en la actualidad.

Además de la válvula, el otro componente crítico del proyecto es el transformador de alimentación. En el circuito, tenemos el modo de conectar la entrada de audio a un amplificador externo de audio para retransmisión de música, por ejemplo. Sin embargo, la fuente de señal también puede ser un micrófono.
