Radio Frequency Location Beacons (Tone Output)

After developing a simple pulsed output for the RF transmitter, it seemed logical to provide a tone output rather than a random noise output. The RF tone beacon was designed to provide a pure tone output from the pulse circuit, whilst not adding considerably to the complexity of the circuit.

The additional components to the circuit centre around a second 555 timer IC.
