Tim, have you tried the "USB sound adapter"? The low end noise that the standard SignaLink has is not there and you can just use VOX for PTT switching. It is also an external soundcard. For only $7.50, you can hardly go wrong!
If you can handle tiny chips, there is also a PTT output that you can bring to the outside. http://www.geeks.com/details.asp?invtid=HE-280B&cat=SND 73, Skip KH6TY > > > Thank you Peter.
