I very much enjoy this idea of feeding links FROM radio receivers, rather than raw computer output.
It makes the internet listener much more of a true listener to your part 15 station!
AND, it could be done from mono AM stations just as easily, so that online listeners would literally be hearing the station from your transmitter.
FURTHERMORE, it was YOU, RFB, who said that part 15 shortwave and longwave were pointless because people aren't listening to those bands, but all of a sudden it makes sense!
Your shortwave station could be fed from a radio to the stream;
Also the longwave broadcast!
This is a thrilling and important idea.
"AND, it could be done from mono AM stations just as easily, so that online listeners would literally be hearing the station from your transmitter."
YES! Some of you who have a Part 15 AM station also have one or more of those lovely fancy tube receiver delights that have much better frequency response..ie wider IF bandwidth = wider audio frequency response. That can be fed into a stream encoder and you have that receiver's quality of audio going out to the world!!
Everyone's Part 15 station can reach beyond the limits!! With the web's help of course! 😀
And yes it does give your station a real sense of people tuning in to your signal. They hear that demodulated RF signal on their speakers, small, large, headphones, earphones or huge massive sub woofer pounding system.
Turn your audience's media player into a radio receiver today! 😉
Now the next step is to convert that demodulated RF signal in it's analog form, and pipe that through an A/D converter and then into either a high speed USB port or a sound card's coaxial/optical digital input.
Lot's of work ahead!

After a full 2 weeks of sending AM C-QUAM stereo audio on my station's streams, I have decided to change the 48kps stream from regular mp3 to AAC+.
The link has not changed so if you have it saved it will still work. However the Flash player had to go because it cannot decode the AAC+ stream properly by default.
The 48kps 44.1Khz stereo AAC+ feed is online and sending out the sweet warm sound of AM C-QUAM stereo...the other two streams remain as they were.
I will be adding a 2nd 128kps 44.1Khz mp3 stream very soon and have that fed audio from a Sony ST-JX220 receiver, the 220A's cousin which did not have AM Stereo capability. It will be used to pick up my FM station's stereo signal and send that out on the 2nd 128kps stream.
Any suggestions, ideas, and reports on the sound please do send them to my station email address at [email protected] or here within this thread.
Thanks to those who have reported in so far! Keep em coming! 🙂

As of September 28, 2012 my stations 128kps stream is now carrying my station's FM audio from a Sony ST-JX220, the US version of the JX220A component tuner.
The 48kps and 24kps AAC+ stream still carry the AM C-QUAM audio. Once things settle down, I will add a new 4th server at 128kps and put the AM C-QUAM audio on that new 128k server. In the meantime, enjoy the best of both worlds on your computer!

I think the idea of putting radio output from a part 15 broadcast on the internet stream is a trully perfect idea.
But upon considering it for my operation, I discover that it is technically complicated to do.
Therefore we need diagrams showing how to do it, for example, with only one computer.
It becomes easier to accomplish with two computers.
"we need diagrams showing how to do it, for example, with only one computer."
Great idea. Perhaps a PDF with photos of my setup as examples along with the diagrams for single or multiple encoding computers. Maybe a PDF for each type of configuration, ie single receiver/computer setup and one for multiple receiver/computer setups.

I have begun the process of creating PDF's for this. Should have them good to go very soon!

i would like pics and info on your free radiate 15.219 setup as well.
the way it was described sounded very interesting and worth looking at. at least to me.

Ahh, the tree squirrel perch. That's what I call it now since the tree squirrels like to sit on top of the box and wiggle their tails across the base of the monopole, which causes the auto-tuner to run back and forth. It's not been used or fired up in about 2 years, but well protected with the outdoor enclosure. Everything inside is as clean and shiny as the day I assembled it all.
The ground plane is not elaborate either, only 10 10 foot long radials since the area where this is located only has about 15 feet of clear ground all around the antenna. It works pretty good and serves as the backup system to the CC station.

Those interested in the forthcoming PDF's on feeding your station air signal onto your streams can get them by email. When they are ready, I will note that here.
They may also be good reference material for the library.
Almost done with the first PDF. I'd say about another week and both will be good to go.
