We have a scheduled ARISS school for next Tuesday, 09 December and would like to do an Echolink feed.

I would appreciate any comments from those that have done so for this event. My concern in feeding the audio from a professional mixer into the PC line input. Any special experiences or suggestions would be great.

Most mixers should provide a decent enough level to drive a PC sound card line input. Ideally you're looking for something like a tape output - many desks have this for dropping mixes to two-track, and they're often labelled as such.
