This new stereo FM Micromitter is capable of broadcasting good quality signals over a range of about 20 metres. It's ideal for broadcasting music from a CD player or from any other source so that it can be picked up in another location.
For example, if you don't have a CD player in you car, you can
use the Micromitter to broadcast signals from a portable CD player to your car's
radio. Alternatively, you might want to use the Micromitter to broadcast signals
from your lounge-room CD player to an FM receiver located in another part of the
house or by the pool.
Because it's based on a single IC, this unit is a snack to
build and fits easily into a small plastic utility box. It broadcasts on the FM
band (ie, 88-108MHz) so that its signal can be received on any standard FM tuner
or portable radio.
However, unlike previous FM transmitters published in
CHIP, this new
design is not continuously variable over the FM broadcast band. Instead, a 4-way
DIP switch is used to select one of 14 preset frequencies. These are available
in two ranges covering from 87.7-88.9MHz and 106.7-107.9MHz in 0.2MHz
