How to Make a Wireless/Stable Microphone with No Frequency Shift
I wanted to show you how to make a stable wireless microphone using a crystal oscillator. I'm sure many of you didn't know about this feature of crystal oscillator. 10 mhz frequency in shortwave, you can do the same circuit with any 8 mhz - 10 mhz - 15 mhz crystals you can find. the range of the transmitter is about 5 to 10 meters in an open area. for more range you need to add an RF amplifier, however, this may result in legal liability for you depending on the country you are in.
