A simple signal strength indicator is presented below:

A simple indicator of the level of the signal on AN6884

The circuit operates over a wide supply voltage range from 3 to 18 volts. The only thing you have to keep in mind the resistance of the resistor R3. A resistor R1, as you might guess adjusts the input signal level.
