1. A radio signal relaying apparatus comprising:
- a personal digital assistant (PDA) with multiple ports of different specifications, wherein the PDA stores music files and a music play program therein, wherein the music play programs selects the music files to be broadcast and sets a broadcast frequency; and
a wireless modulating module, which connects to a selected port among the multiple ports of the PDA and modulates the selected music files to become radio signals at the set frequency, wherein the radio signals are further transmitted by the wireless modulating module.

Abstract
A radio signal relaying device has a PDA and a wireless modulating module connected to the PDA. The PDA is provided with multiple ports of different specifications such as a memory card slot, a USB interface or a serial port. The wireless modulating module is selectively linked to one of the ports to modulate music files stored in the PDA. The modulated sound files can be transmitted in the form of radio waves and then be demodulated and played by any radio receiving device.
