+**rpitx** is a radio transmitter for Raspberry Pi (B, B+, PI2, PI3B,PI3B+,PIZero,PiZerow) that transmits RF directly to GPIO. It can handle frequencies from 5 KHz up to 1500 MHz.
 
 Before you transmit, know your laws. **rpitx** has not been tested for compliance with regulations governing transmission of radio signals. You are responsible for using your **rpitx** legally.

 # Hardware
-Plug a wire on GPIO 18, means Pin 12 of the GPIO header ([header P1](http://elinux.org/RPi_Low-level_peripherals#General_Purpose_Input.2FOutput_.28GPIO.29)). This acts as the antenna. The optimal length of the wire depends the frequency you want to transmit on, but it works with a few centimeters for local testing.

-### Frequency Modulation (FM)
-**pifm** converts an audio file (Wav, 48KHz, 1 channel, pcm_s16le codec) to Narrow band FM (12.5khz excursion) and outputs it to a .ft file.
