It operates based on a sophisticated radio IC and has a powerful antenna coil with a high-grade ferrite core so no external antenna is needed. It includes a volume control and a two-transistor audio amplifier with a power transistor to drive the speaker. Easy to build and to operate, as no alignment is necessary.
