Question for the community about the plausibility of an idea

GNU Radio
#1

Would it be technically possible to create a virtual band of frequencies
on
a server and multicast that out to interested participants?

Think amateur radio or citizens band, simulated online. Narrow-bandwidth
voice in multiple modes injected into an IQ stream to give the illusion
of
a radio network.

I can’t tell you why I’m attracted to the idea. Every since the
internet
became more than a talking point, i’ve dreamed of a networked cb radio
where chaos and camaraderie intermix.

Thanks for entertaining my idea.

Hi,

Do you mean something like this?

So IRC with voice instead of text?

No, I think he literally means virtual radio over the internet, with I/Q
samples being multi-cast all over the place.

Can’t think why this would be useful as anything other than an algorithm
testbed for people without access to actual, over-the-air, signals.

For those of us like me that blindly click on links :slight_smile:

Its probably more for fun than for testing.

Re-reply (because this new email client confounds me)

Yes. Very much like websdr. Except remove the real RF. Simulate noise.
Put internet users into the bandscope. It would literally be an online
two-way radio.

I know, its a hard sell for scientific types. But, it has value…
albeit
in strange places. For instance: [through some online-broadcast forums]
I
know of war museum that has implemented in in-exhibit radio stream. It
includes period-correct transmitters/receivers. They modulate the whole
thing with a digitized playout server. How amazing would it be to put
that
servers playout into a virtual spectrum and allow web visitors to tune
the
dial in search of propaganda, radio from the front-lines, and
clandestine
transmitters?

Virtual walkie-talkie with smart-phones?

For me, radio lost its appeal when analog dials disappeared. But when I
stumbled upon websdr, and these rtl devices, I went bonkers for it
again.
I love the hum/hiss/crackles/pops and I love an analog tuner (i know i
know). Add pirate radio, regular folk talking, and the promise of an
occasional world-wide contact, and I’ll put my money into a hardware
device
in a heartbeat (raspberry pi with an astatic D104 microphone and a
needle
the bounces when people talk? i’ll take two).

I had wanted to tackled the idea myself, but its above my meager
abilities. And to be honest, i’m not sure how well it would run with
say,
1mb bandwidth and several thousand wannabe truckers.

But thanks for entertaining the thought.
