Как данную схему можно переделать под двойное преобразование ❓
И как повысить число каналов ❓
( И будьте так любезны - укажите точные изменения в схеме 😃 ).
Ну, это будет сааааавсем другой приемник!
Просто так переделать на dual conversion нельзя.
Как данную схему можно переделать под двойное преобразование ❓
До скольки?
Если до семи, то:
выводы 2 и 7 микросхемы DD1 - соединить,
выводы 1 и 9 микросхемы DD1 - соединить,
а выводы 5,4,3 - будут дополнительными каналами.
Можо ли замеить КР1170ЕН3 на 78L03?
