[w4rs at earthlink.net]

well i got my ic-7200 working on reading its band and freq and mode in dx4win ver 8.05. when i open the psk window, it come up, but does not show any sig's and if i hit transmit, it shows its red, but not keying the radio. when i open ritty, it says it can not open mytty, but it open's it. but nothing showing and no trans? the 7200 has a built in sound card and is connected to the computer with a usb cable.any ideas what my old butt is doing wroong?
