While I have been monitoring ATC comms for almost 20 years now I have never really investigated running a live-feed. I guess what I would like to know is the following:
1) What software needed?
2) Is a standard soundcard good enough? I have several systems with mostly integrated SC's
3) How much bandwidth is used? Will it interfere with my day to day work? I have a 3mb DSL line running at 1745 Down/400 up
