Hi everyone
I have looked in a lot of places but cant find what i want
I want to make a radio transmitter and receiver that operates bellow normal radio stations (FM 80Mhz to 108Mhz). So inother words a transmitter that sends radio waves on 40 to 70 Mhz
How can i do this. Do i use a larger variable capacitor next to the coil or make the coil bigger?? Are there formula to calculate the frequencies?
Many thanks,
Robin
