Hi All is anyone using signalink usb with dx4win. I cannot use it unless I change it to default sound card. it does not come up in the drop menu in pref/ control/psk sound card. only sound card 0 1 2 and 3. any help. I am also struggling with mmtty also.. but I have not used that programme before so I don't know my way around it. All The Best g0vxe Dave
