[MLB-WIRELESS] OT: Tuneable scanner online.

[Steven Haigh]

Basically, there's a radio receiver hooked up to the COM port on my
firewall PC. The line out from the receiver goes to the line in of a
soundcard. This then gets crunched live into an MP3 stream (22Khz
32000bit mono stream). This takes about 30% CPU usage on a P3 450.

This data is then streamed to a shoutcast server at
http://wireless.org.au:8000 - because my home connection can't handle
more than 3 listeners at once (damn optusnet 128kbps upstream!).

The tuning is done via a PHP script interfacing with a program on the
PC. This basically sends commands to the receiver to change frequency
etc.

At the moment, I'm just running on a crapping little antenna inside the
house, however when I get some other radio gear up, I intend to put up a
proper discone antenna outside. This will improve reception by more than
tenfold.

If you're interested in more details, then feel free to contact me
offlist.
