Hi all I have trying to use an old Toshiba laptop 4000CDs in the shack, the internal sound card is pre DSP, so Linrad and GLFER dont work nor does any of the wsjt type software. Has anyone ever seen a sort of outboard sound card that will connect to the com ports ?.. If not it might just end its days as a firewall and dxcluster server. Richard G8JVMLINRADDARNIL
