I am receiving fine with WSPR and my K3. The K3 is in the "DATA A" mode. When I transmit, I get an error message that "wspr.exe encountered a problem and needs to close" I send the error reports. What next? I have tried a number of combinations of com ports and audio in/out settings all the same results.

Thanks,
