fm transmitter signal range
Hello all
I have a modelship wich I want to keep in the range of 5-10meters from an fake island in a pond/pool. I think I need to build an FM transmitter to place on the island and a receiver to place on my boat. The boat has a constant speed, wich I dont want to change. I was thinking, if I can make the servo-motor in my boat odd, and when the motor is turned on, the servo makes the boat go straight and when the boat get out of the range of the island, the servo turns on, doing so, that the boat turns. When the boat is in the signal range again, the servo switches on, and the boat will sail straight forward again.
I has searched the web and found this circuit for the transmitter. It says that it is a low range circuit, so it should do it. But this circuit is build for microphone input. The question is, can I remove the microphone component and then the transmitter will send out a constant ON signal, or how does it work?

Do you have a nice and simple circuit for a receiver. It only has to control 1 switch and thats the servo-motor.
Hope you can help me, like you did with my PWM controller for my DC motor, it works perfect.
