The YFM-2 radio circuit is very simple, with a total of no more than 19 components. Despite the small number of components, it includes both surface-mount and through-hole types, making it ideal for beginners and those who want to practice soldering surface-mount components. Its features include:
-
Digital Automatic Gain Control (AGC) circuit for more stable signal reception.
-
Low power consumption, with a total current of about 19mA when powered by two AA batteries.
-
Supports global frequency range of 76-108MHz.
-
Memory function for radio stations, automatically returning to the last station and volume setting upon power-up.
-
Simple circuit design that is easy to assemble and works without needing any adjustments.
