Hi All,, I'm using the Digi Keyer (microHam), with a built in Soundcard in conjunction with the DX4Win (Vers7.2) to control my Radio. Is there any way to tell DX4WIN to use this card for PSK32 instead of that one built in in the Computer/Laptop ??? Many thanks for any ideas,, Vy 73 de Helmut OE1MHL Helmut Mayrhofer mailto mayrhofer.helmut at aon.at
