Transmitters and the Law

This circuit can not legally be connected to an antenna!

It's power is so low that even with an antenna. it's range would be only a few metres.

Transmitter Details

FM-VHF-Transmitter.GIF

This transmitter circuit has been built and tested and it has a range of a few feet if no antenna is connected.

Construction

This can not be built onto prototype boards because the stray capacitance between the tracks is larger than the wanted circuit capacitances.

Beware: Some of the diodes are being used to support the wiring and are not electronically relevant!
