Same here...

I asked Andy (UZ7HO) about this and he whipped up a full-duplex version 
of Soundmodem in a matter of hours. Works great with the DCD is 
disabled. If you send him an email, I'm sure he'll send you a copy. His 
email address is available on QRZ.

Plan on doing that on the next pass!

Thanks Scott...
