So I made the actual PCB layout, solder the components and when I test the circuit, there was no noise coming out of the speaker, but I can hear the " snap sound " inside the speaker whenever I turn on the main switch meaning there is a voltage flowing. I cant transmit and receive in either the walkie talkie (cause I made 2). In the picture below, can you tell me where among the 12 pins of the push switch should I connect each T,R, COMMON(arrow)? cause I think there is where I made a mistake. Please help, thanks.
