Sure you can, it's called iboc. Its signals cannot be decoded with a "standard" radio receiver, and it is in direct opposition to
FCC law which requires(d) that transmissions in the broadcast bands not be encrypted but detectable by standard circuits.
I'd love to see the official retraction notice for this law. I think it was "conveniently" ignored for ibiquity.
SCA audio can't be decoded on a standard receiver either.
SCA receivers were not available to the general public, SCA transmisions were a paid services at low fidelity and
subject to some really disagreeable noises. I remember well how the old National Cash Registers back in the 70's tore up the the SCA music on the store intercom at the grocery where I had my first job. Not noticable down at the floor level much, though, and good enough for
in-store background music. A 67 khz take-off could be added to about any FM if somebody wanted to.
It would not be necessary to buy proprietary encode/decode methods. You could even roll your own, if you cared to.
This morning's Chicago Tribune had a half page "fluff story" about "dialing up the death of AM/FM radio".
It compared a few 'internet radios" and went on and on about the benefits and features, but naturally no real
helpful information to help the avearge person understand that they don't work like real radio.
You can't take it to the beach, you can't take it anywhere that you don't have access and a login to a wired network
within a hundred or so feet. You can't listen to a show then go get in the car and just continue listening to program on the car radio.
You need another subscription data service for mobile. Then there's no mention of the bandwidth hogged.
If your spouse begins to download some other data, they find the download slow and you'll find the audio stream halts.
You can be listenng to a show on the car radio, get home, and find the audio of what you've been listening to simply
isn't on the internet, or that the internet is getting it's "own" feed from that station, different from the air signal.
Too many internet stations won't or can't afford enough bandwidth to justify paying for this.
The minimum acceptable rate for mp3s and listening somwhat closely is 128K, 96k for causual low background music.
The internet is a useful medium for music delivery, or any data, but it looks as foolish trying to imitate radio
as Radio does does trying to become digital.
More and more, to me, what defines radio is:
the very nature of radio distribution which cannot be "owned", any more than sunlight can be "owned".
At this point when we still have "radio", the attempt is to get you to forget all normal rf aspects and benefits, and begin to PAY for what
you once got for free. Can anyone say cable TV? " SURE there'll be no commercials! You really believe that?"
And they all did, and now somone siphons 20-100 dollars from every cable household monthly and all the commercials came back
and a new breed of vermin was born, the "all advertisement" channel.
I recognize the that corporations drool over the opportunity to sell us bottled air with the perfect marketing angle.
And those who are subject to marketing will "know" they are buying the "Finest, most delicately handled" air possible.
To this day, the ionospehere and the laws of physics haven't sent me a bill with an activation charge, a service fee, a plan explanation,
a data fee strucure, download caps, taxes, surcharges, or disclaimers relating how the service will not "always" work,
but that it will be "normal" for the service to not always work and I must agree to accept that, etc, etc.
Or at least they haven't figured out my address to send the bill to.
