Abstract

UN COMPAGINADOR DE RADIO CAPAZ DE CAMBIAR LA FRECUENCIA DE RECEPCION DE LA MISMA, A GUSTO, Y QUE TIENE UN OSCILADOR DE CRISTAL REEMPLAZABLE (82). UN DISPOSITIVO SELECTOR DE FRECUENCIAS DE RECEPCION SELECCIONA UNA DE LAS SEÑALES DE LLAMADA QUE TIENE UNA MULTITUD DE FRECUENCIAS PREDETERMINADAS QUE SE EMPAREJA CON EL OSCILADOR DE CRISTAL (82). UN BASTIDOR (102) ESTA FORMADO CON UNA PRIMERA ABERTURA (102A) PARA PERMITIR QUE EL OSCILADOR DE CRISTAL (82) SE FIJE O DESPRENDA SELECTIVAMENTE DE UNA PLACA DE CIRCUITO IMPRESO (104), Y UNA SEGUNDA ABERTURA (102B) PARA PERMITIR QUE EL OSCILADOR SE INSERTE O EXTRAIGA SELECTIVAMENTE DEL BASTIDOR (102).
