Voyager on a 9v Battery

Ali the elements of good design have been achieved in this project. The Circuit has a slightly higher output than the 3v Circuit above, but most of the voltage is lost across the emitter resistor and not converted to RF. The main advantage of this design is being able to connect to a 9v battery. In a technical sense, about half the energy is wasted as the stages actually reguire about 4v - 5v for maximum output.

The Voyager has been copied by many kit-makers but nonę has surpassed its performance.

Here is a "knock-ofT of our older design. It is mounted fiat on a 9v battery:
