Are you a a ham? .... If so you can build and test high power radios .....

Regarding digital, there are technology now.... Pactor, Amtor.... look for software defined radios....also...

i am not looking for a radio that requires software. my circuit is for wireless headphones. the circuit that i was using is attached. i only modified the values for 15MHz and 20MHz (one for each headphone). all i did was modify the values for a simple FM transmitter circuit, the problem that I'm worried about is interference, if i switch to digital, then i need not worry. and range is not an issue, ideal a maximum of 10ft.

Using a digital signal will not solve the analog noise problems, the noise will still be there it doesn't just magically go away when you use a digital signal. What exactly are your project requirements? You may be able to find a commercial product which meets your needs.

I find it very difficult to believe that you've searched Google for any length of time for wireless digital audio transmission and found no good links to provide information.

i have searched Google multiple times for circuits to help me, but i have found nothing that resembles what i want. the only wireless headphones that Google gives me are big and clunky, or the only circuits work by infrared. what i am looking for is a set of wireless headphones that can be made into the size of an ear bud. and i was told to either upgrade to digital transition or to move into the frequency where the old analog TV signals were transited, but i heard that that specific air band frequency is being auctioned off.

You could just buy a set of wireless headphones. They're not that expensive.
