  1. Hi, I have some questions about the AM transmitter by Andy Collinson. http://www.electronics-lab.com/projects/rf/011/index.html 1. What type of microphone it is used in the circuit. Is the normal microphone using for our laptop can be used? What is the purpose of using the resistor R1 and capacitor C4? 2. Can i replace the C1 with smaller value of the capacitance? Thanks!
