[Lowfer] WSPRX with EM-U 0202 problem

[jrusgrove at comcast.net]

As I've mentioned before ... check the sound card sampling rate when running more than one program. 
The first program to start will lock in a particular sampling rate which may or may not be that 
required by other programs. In some cases this can be managed by the order that one starts multiple 
programs.
