In this modern era all electronic devices have grown rapidly. Starting from home appliances, communication tools, vehicles, and much more. It used to communicate telephone lines using cables, to apply radio frequency waves for home phones to mobile phones. In addition to being applied to telephones, radio frequency waves also have long been applied to two way radios or walkie talkies. In the eighties, walkie-talkies were very popular to communicate at close range. And many walkie talkie kits are available on the market almost all over the world.  But for now walkie talkie kits are hard to find, but still available in some online stores.  For people who have a hobby of electronics, making your own walkie talkie is a fun thing. There is a certain satisfaction when we can make wireless devices with our own hands. For that moment I will share a series of walkie talkie toys that many circulating in the market. This walkie talkie circuit is quite easy to make, becaus...

Fm radio is a radio reception fm waves. These radio receivers some are fully using transistors, and some are using ICs. For those who use transistors usually called transistor radios. With the rapid development of the times, the radio changed into smaller ones,  and with few components. And changed from analog system to digital system. Some analog electronic enthusiasts, transistor radios have a special place. Transistor fm radio circuit Dispite its simplicity, it is easy to repair and modify. To help you and your transistor radio project, here is a transistor radio picture. Which you can use to create and learn it. May be useful.

Many of us think that to make walkie talkie is very difficult. But actually to make walkie talkie is not as difficult as imagined. For example, a toy walkie talkie consist of a few transistors. Based on a circuit of walkie talkie toys, we can make a simple walkie talkie. Of course with complete components we are very likely to make it. It's just that the hard component is the inductor for frequency tuning. The inductor for tuning consist of three windings, two windings are combined with three connection point. And one winding are separated for the antenna. For other components, like capacitor and transistor are not difficult for us to find it. I hope this walkie talkie transistor circuit diagram will help you, and your project. Walkie talkie transistor

Transistor Walkie Talkie Circuit Diagram In general, this transistor walkie talkie circuit is the same as other walkie talkie circuit. This transistor walkie talkie circuit, consist of transceiver and audio amplifier parts. But in a walkie talkie circuit, there is an audio transformer, and some are not. Altought different, but both have same function to amplify the audio signal. Transistor walkie talkie circuit diagram Walkie talkie circuit that do not use audio transformer, only use transistor on the audio amplifier, usually consist of four transistor. As for the transceiver circuit, uses only one transistor, but there are also some that use three transistor for more sensitivity. This transistor walkie talkie circuit uses crystal oscillator for frequency stability, while the radio is in transmitter mode. This transistor walkie talkie circuit works the same way as other walkie talkie, that is the change of the circuit during receiver mode and transmitter mode.

This time i will share different walkie talkie circuit. Basically this walkie talkie circuit almost the same as with other walkie talkie circuit. Three transistor walkie talkie It's just that in this circuit using three transistors on the transceiver. Two transistor as receiver and one for transmitter, and the transceiver part is separate. The reason the receiver use two transistors is to increase sensitivity of receiving signals. So the circuit image for this time may be useful.

Basically this one transistor walkie talkie circuit, is the same as with other walkie talkie. It's just that in this circuit, some audio amplifier transistor are replaced with audio amplifier ic. It aims to reduce the size of pcb, so that walkie talkie can be made with smaller size. L2= 3t, 2t, 2t One transistor in question is on transceiver only. This section is the most important on a walkie talkie, because this section serves to transmit and receive radio signals. So it can be used to communicate. For an explanation how this walkie talkie works, we will discuss it later.

Toy Walkie Talkie Circuit Diagram

This circuit is the circuit used on walkie talkie toy. This circuit is very simple, but while it looks simple, there are two different sets in it. Which have different ways of working. The first is the transceiver circuit, and the second is the audio amplifier circuit. Both are combined into a series of radio transceivers. Transceiver circuit function send and receive radio waves. Sending in the sense of converting audio signals into radio waves.

Simple Walkie Talkie Circuit Diagram  This simple walkie talkie circuit is the same as with another walkie talkie toy circuit diagram. It just use a few of transistor for amplifier circuit, and one other for transceiver circuit. Simple walkie talkie circuit diagram  This circuit also use crystal oscilator for more stability, when transmitter mode turn on. The most important part on this circuit, is LC circuit. The LC circuit is made of with combination of ferite core inductor, with ceramic capacitor.   The function of this LC circuit is for set the frequency. This simple walkie talkie circuit is very easy to build, for your home made walkie talkie project.
