>NCO: 12 Numerically Controlled Oscillators generate carrier frequencies (505–1605 kHz)
This seems like a crude way to do it.. why not provide all 110 carrier frequencies by using a polyphase channelizer? The bandwidth of the entire AM broadcast band is pretty low..
Yes, that's very true. It would make much more sense to hit all channels, at the same time, maybe they want to use some of the channels for comms even during an emergency?
