Hi Steve and List: 

Well I did reduce the input to the soundcard and it was saying overload not buffer as I initially thought. 
With that done, how do I get text to appear on the screen for decoding? 
When I press the left or right arrows, the program locks up. 
This is probably due to Digitalk not able to tune the connected transceiver. 
I'm not running an actual sound card interface, just an audible cable connected. 
I did get my XYL to have a look at the screen and the blue lines are coming up on the bottom, probably the received signals. 
However, there's no way to click on them or get to them in any way.  

TNX: 

Mike
