[hpsdr] Schematic capture software

[Greg - ZL3IX]

I hope that this is not considered off topic.

I would like to make my own audio board to use with Atlas and Ozy, so I 
am looking for a freeware ECAD package.  What are group members using, 
and what do they think of the various options?  Probably best to answer 
me direct, and I will post a synopsis to the group if anyone else is 
interested.

Thanks + 73,
Greg, ZL3IX
