I'm using an LM386 for voice amplification. The transmitter transmits the signal from the tank circuit on the correct frequency but without voice.
I'm a beginner and a hobbyist and I'm still trying to understand the process.
- I tried using a power supply from 3,3 V up to 9V and it made no diffetence.
- When I touch the microphone the signal modulates a bit.
- The circuit is tested currently on a breadboard and soldered on a perfboard.
- I have an SDR, an osciloscope and a signal generator.
