And this portion of the circuit tends to take feedback from the user. The audio input happens to be the first section of the walkie talkie. In the transmitter section, here are the parts you’ll need: Audio Input Also, we’ll break each of the sections into five different parts to help you understand the process better: Mixer, audio input, RF input, audio output, RF output. First, we’ll talk about the two major sections: transmitter and receiver. You’ll need a walkie talkie circuit design before you can proceed to make one. On the other hand, a full-duplex is when both parties can receive and send simultaneously. However, only one can receive while the other can transmit at once. So, the half-duplex refers to a bi-directional communication that occurs between two people. Plus, there’s usually a switch in the circuit that allows you to change between the different modes. That said, your communication on this device can either be full or half-duplex. While you’re at it, ensure that your preferred frequency isn’t an operating FM station because it will disrupt your conversation. The goal here is to opt for any frequency between 88 to 108 MHz. And the same thing applies to the receiver. In other words, if you want to talk to someone with this device, you need a set of FM radio and FM transmitters. The FM radio acts as the receiver while the FM transmitter helps to send the voice. What’s the Idea Behind the Walkie Talkie?īefore we dive into the steps of building a walkie talkie, you need to be clear about how it works.įirst off, it’s crucial to know that the walkie talkie is incomplete without an FM transmitter and radio. Plus, we’ll highlight how you can use the device correctly. Stick around-as we’ll take you through all the necessary steps you need to build a walkie talkie-with its complete circuit board. Also, we’ll show you how to create the walkie talkie over an FM frequency band alongside a range of about 250 meters. Of course, you can build this handheld portable radio-as long as you stick to an exemplary diagram and use the suitable component. But did you know you could make a DIY walkie talkie? The device is even more helpful when you have issues with the unavailable or inadequate network coverage. A walkie talkie is a simple, easy-to-use, and robust device that’s excellent for outdoor use.
