I thought to build a audio transmitter out out RF-2400W with internal chip IC BK2421 to send music from mp3 player to another location where my speakers are located. The RF-2400W Tranciever having BK2421 IC can be used for remote controls. Are there anyother articles or information about this on web other than http://ydn-myst.com/?p=168 . I think this module is very cheap when compaired to thers but no one really know how to configure as audio transmitting. Can anyone help with this.
