The receiver uses a clever direct conversion design using an NE602 with some AGC applied to it. Like the RockMite, it uses some front end crystal filtering to help overcome dynamic range/overload issues, but with the limitation this is a single frequency radio, for example parked on 7.030MHz, the QRP frequency. Still, a full 5W on the QRP frequency will permit plenty of QSOs.
