Compact 5-LED S-Meter with Calibration

By PY2BBS

This project features a compact, 5-LED general-purpose S-Meter, designed for use with various radio circuits. It utilizes the LB1403 IC, with alternatives like LB1413, LB1423, and others. The circuit's design allows flexibility, with one version featuring a trimpot for calibration and another without it for more compact setups. The LB1423 is preferred for its low current draw and dB-calibrated scale. This S-Meter offers an efficient, customizable solution for measuring signal strength in amateur radio applications.
