Hamic, the Ham Intelligent Calculator, is a freeware program designed to simplify a wide range of calculations commonly required by ham radio operators. Although created for the amateur radio hobbyist, Hamic is also valuable for anyone working with electronic circuits, antennas, impedance matching, or radio-frequency principles. The software features a user‑friendly graphical interface capable of solving simple resistor, capacitor, and inductor networks, as well as complex circuit configurations such as L, Pi, and T networks. Hamic supports calculations for SWR, reactance, resonant frequency, antenna impedance, inductance of an air-core coil, and wavelength/frequency conversions. One of its most powerful features is the ability to solve for almost any unknown variable in a circuit, even for L networks without requiring Smith charts. Users can save their work to worksheets for future reference, making Hamic a versatile tool for experimentation and problem-solving in RF and circuit design.
