Description

Трансивер "Полевик", авторства R2DNN.

Обсуждение конструкции можно прочитать на форуме qrz.ru.

Основная схема трансивера тут - http://qrp.ru/forum/9-%D0%A1%D0%B0%D0%BC%D0%BE%D0%B4%D0%B5%D0%BB%D1%8C%D0%BD%D0%B0%D1%8F-%D1%82%D0%B5%D1%85%D0%BD%D0%B8%D0%BA%D0%B0/13211-TRX-%D0%9F%D0%BE%D0%BB%D0%B5%D0%B2%D0%B8%D0%BA?start=10#50390

Сделана попытка заменить УНЧ на LM386 и добавлен синтезатор на Arduino Nano + SI5351.

Это "заготовка" для дальнейшей доработки.
