1000m single tube oscillation (C8050) FM transmitter circuit

For an amateur radio enthusiast, getting a good FM transmitter circuit is like finding a treasure. However, the circuit in the book cannot obtain sufficient transmit power due to many practical reasons. Now I will introduce a circuit with satisfactory power. circuit. Let’s look at the circuit diagram first: the circuit is very simple and does not require debugging. Just make sure that the components are connected correctly and there are no false soldering or short circuits and it will work normally. Its power is about 60mw, so it is relatively large. It is generally recommended to use rechargeable batteries, which not only can provide high current, but are also economical and ideal choice. But I don't advocate using a transformer for power supply, because it requires a high filter circuit. Author: Guangguang
