In this example the Micro Radio Station is a PC with a built-in FM Transmitter PCI card. The
output of the PCI card is connected to a so-called booster amplifier of 5-15 Watts, and the booster is
connected to the Vertical FM Transmitting antenna via a cable. A headset (headphones and a
microphone) is connected to the PC.

Free software such as Winamp operates the play list and the playback of sound files, and the editing
software is bundled with the soundcard.

1 PCI Ultra Max RM Transmitter
1 Booster amplifier 5- 15 watts
