John, I was very interested in having an FM transmitter with higher output power since I intend to use it for talking to people in my warehouse. I have seen a lot circuits but they have very less output power, usually ranging between 5W to 10W. Could you please fix the links of the RF circuit section? It is a crucial section of the circuit. Also, I can’t see the image of the RFamp circuit. If I can perhaps get these two, I’ll figure out the rest.
