<BR>OK , já percebi.<BR>
esses trimer amarelos são fraquinhos, isso&nbsp; é bom para RX.<BR>
isso com 100W faz logo fumo.<BR>
O melhor é substituir tudo por variaveis ceramicos.<BR>
Ou então meter valores fixos, aproximados em condensadores de MICA.<BR>
depois ajustas nas bobines.<BR>
fica muito melhor.<BR>
