Hi Steve, Try DM780 (HRD) and you can see what Tim is talking about, it doesn't have the sound card harmonic and is NOT a Flex issue. It is there with any other Radio you run FLDIGI on, the difference from other Radios is, with the Flex / PowSDR YOU CAN SEE IT.

Flex-3000 Windows 7 64 PowerSDR v1.18.3 Driver Version 3.5.0.7171 Firmware 1.2.5.6 Licensed version of VAC fldigi 3.12.5 After the Suggestion that it was RF getting into the system I I checked all my RF grounding and re-ran my test into a dummy load with 0 RF out. The Spur is still present in the lack of an RF presence. It was suggested I modify my transmit filter. That isn't the way PSK31 works. How do I deal with this visually obvious unwanted sideband transmission? Do I need to take this up with Flex-Radio as a warranty issue?
