FCC To Repack Channels

I'd also increase transmitter power.

I'm sorry, but I just half a year ago, built a software defined radio on my own, that picks up anywhere between 40MHz and 1.7GHz. It only has about 3MHz bandwidth (2MHz without any skipped "frames"), and I really don't want to have to redesign it to pick up some silly digital signal it probably can't decode anyway. I like FM as it is, and all of my radios in the house already support it.

Is there presently available software for SDRs that will decode the digital signals already in use in the FM band? I suspect that you have noticed the IBOC "sidebands" attached to many analog FM signals, and *perhaps* are already decoding them.
Or perhaps not?
