To provide a feed you'll need a Cable Modem or a DSL connection to the Internet. You'll connect your scanner to the Line In input of your computer's sound card using a mono audio cable. I'll provide you with the software that is used to record the audio from your sound card and send it to my server for others to listen to.
I'll create a web site like ScanSpartanburg.com to be the home for the feed so that it's easy for people to find. The ads on the site will cover my bandwidth costs associated with hosting the feed.
If you would like to provide a Columbia feed I'll convert my existing ScanColumbia.com site to being the home for your feed instead of for Columbia County, Georgia since the site has been without a feed for a long time.
