Here is a toy walkie talkie circuit diagram, this circuit uses only one transistor. The transistor in this circuit, functioning as simple transceiver.

As for the amplifier, replaced with ic audio amplifier. This ic serves to replace transistors and audio transformer. In this way, the size of pcb can be made smaller and compact. So the size of walkie talkie too, becomes smaller.
This circuit is quite easy to make, because it uses few components.
Hopefully this circuit can help you, to make your own walkie talkie.
