Description
Description
Frontend board for GeFest TRX project.
The purpose of this project is to build a transceiver exclusively on germanium transistors. Double frequency conversion is used. The first IF is 23 MHz or 10.7 MHz. The second IF is 200/465/500 kHz. The transceiver has a modular structure with frontend boards, an AM processor, a SSB-processor, a FM-processor and an audio amplifier.
