I want to record Rush Limbaugh every day and have it available on my computer, and then maybe once a week burn a cd and listen to it in my car on the way to work and maybe play it back some at work too since my radio reception sucks and I'm not always in my office 12-3pm EST.

Rush's own page has a listen live link  on www.rushlimbaugh.com/home/today.guest.html

I'd like to capture that stream and save to disk.

Other question is Im able to do so, how much disk space would each 3 hour show take?  A music cd is what 800 MB and has 74 minutes of music capacity?

Thanks

These will do the trick.

You can probably google up some free versions if you search for "record streaming audio", although this one does offer a free demo.

On the 2nd part, if you convert your saved sound files to MP3 format, you should be able to get 30-50 MB per hour depending upon the quality settings you select.
