I was not actually being sarcastic. At least I did not mean to.
I was actually trying to clarify that someone was actually asking for a total software-solution for a radio transmitter.
Apparently I've been around nerds too long. I can't imagine that someone does not understand that you need hardware built into a unit to do this. I was not trying to be difficult, it just rather "blew my mind". I probably need to get out more.
Now, in theory one could add a device like an FPGA to a product and then design and download "hardware" onto the FPGA. But that's logic circuitry, not something like a radio transmitter, where you need a number of "RLC" elements to make it work, specially designed parts such as frequency-specific amplifying transistors and antenna
I expect there will come a time when we can actually configure physical elements inside a generic part for functions like a low-powered transmitter, but not yet.
There are "software radios" now, but they work by using special radio hardware to receive the signal, then DSP to "tune" the proper frequency. I had assumed that the questioner here knew that, and then expected it was easy to build a total software transmitter.
Yeah, your XM radio can do it because it was designed to have that capability. One thing you could do is look for an aux interface for your car stereo; this will sound a whole lot better than the FM transmitter, and it may not be much more expensive. BlitzSafe makes a number of these interfaces, both for "aux" and ipod devices.
