Falando em montagem de rádio.

Meu blog fala de rádio mas desde que organizei minhas tralhas de eletrônica eu ainda não montei um radinho se quer, vou pensar mais neste assunto e dar jus ao nome do blog: Eletrônica Ondas do Rádio, eu tenho a eletrônica como hobby e vou me dedicar mais ao meu passatempo favorito e começar buscar alguns circuitos para a montagem de um bom radinho AM pois capacitores variáveis é o que não falta na minha sucata inclusive os metálico de ar, em breve vou postar alguns aqui, até mais...

Placa do rádio Motoradio RP M-31 de três faixas.

Olhando minhas sucatas eletrônicas encontrei a placa intacta do rádio Motoradio RP m-31, agora é partir para restauração total da placa irei limpar com álcool isopropílico e troca de componentes.

Voltando fazer DX com meu rádio NKS.

Eu voltei a fazer dx com meu NKS e pra minhas surpresa ele ainda funciona e após uma limpeza leve com limpa contato ele voltou a ativa, eu conecto uma antena improvisada e o rádio melhora muito a sua recepção é show eu adorei em breve farei um vídeo e descreverei a antena, bom por enquanto é só.

Auto rádio BAk.

O rádio é bom e tem um áudio com bom volume, comprei para fazer um som ambiente e o jogo de luzes no painel é  bem interessante, gostei muito.
