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.
