Radio Short Wave DIY

Hi, I am a shortwave listener and like to make myself my receivers. This is my home-made short wave radio receiver. It is a superheterodyne circuit based on IC TEA5570 w/ FET pre-selector on antenna input. Here I was receiving a 40 meter Radio Ham conversation. This receiver covers a contiuous band from 3.3mhz to 14.6mhz. Eu sou um radio escuta e construo meus receptores. Este é meu receptor de ondas curtas que construi para explorar ondas curtas. O circuito é um superheterodino baseado no IC TEA5570 com pre-seletor a FET na entrada de antena. Aqui eu estava recebendo conversação entre Radio Amadores na faixa de 40 metros. Este receptor cobre a faixa continua de 3.3mhz to 14.6mhz.
