We all need help.

First thing I suggest you do is find out what the LAW is in your area for radio broadcasting.

I'm assuming you're not just building a transmitter just to look nice - especially with a 500m wavelength.

What sort of CDs? CD roms or rewritable? What sort of power supply would you like it to have? From a wall, or a generator?

Give me the answers, and I'll see what I can do.
