DESCRIPTION
Description:
The YFM-2 type radio circuit is very simple. The total number of components does not exceed 19. Although the number of components is small, it includes two major types of components: patch and plug-in. It is suitable for novices and small partners who want to practice soldering of patch components.
Features:
1. With digital automatic gain control (AGC) circuit to make the received signal more stable.
2. Low power consumption. When powered by two AA batteries, the total current is about 19mA.
3. Support the global frequency band 76-108Mhz.
4. Support radio memory function, the next time you turn on the phone, it will automatically return to the radio station and volume when you last turned off the phone.
5. The circuit is simple, easy to manufacture, and can work normally without debugging.
