AVT5527 A + - RX Lidia 80 Digital. PCB and programmed layout

Description

Simple listening receivers are still very popular devices among amateur radio players. They cost little, take up little space and allow you to successfully conduct good listening in a variety of conditions. The popular, easy to make homodyn receiver "Lidia 80" according to Włodek SP5DDJ has been designed so that it can be successfully used in the basic version, but it can also be extended with additional functionalities. The author of this project, encouraged by positive experiences with the basic version of the receiver, decided to expand it with new functions. Appetite grew as food and therefore the last, presented version of the device was equipped not only in the measurement of operating frequency, but also in its regulation and stabilization with a minimum of 10 Hz, graphic S-meter and automatic regulation of ARW gain in the range of 12 dB (two units "S").

The receiver is designed for people who want to deal with amateur radio. A properly assembled and tuned receiver enables listening to amateur telegraph and single-streamed stations using a dipole or wire antenna (Long-Wire).
