I do the same as Nick, except I leave everything as is and record in stereo. Don't bother about trying to hit the start of the show in Audacity recording, just hit the red record button, click on your show and delete the unwanted dead air after you press stop.
You may also get a bette rsignal strength if you "Normalize" the recording. Simply hit "Edit" "Select All" then hit "Effect" "Normalize" and use the default -3dB, dah dah more signal strength.
If you want to listen to the programme through Audacity, just save the file as an Audacity project, it then reloads a lot quicker than a .wav file.
