A couple of thoughts.
- make sure PowerSDR and Fldigi are using the same sample rate for VAC
.. To be certain, start PowerSDR first, enable VAC, then start FLdigi .
- When I operate Digital modes I have set up a 1Khz wide transmit filter
and various receive filters centered at 1500kHz . I click to tune in the
station, then hit the QSY button in Fldigi to center the station at
1500kHz (you must have CAT going) .. The 1kHz transmit filter makes a
very clean transmit signal .. A 60-100Hz wide receive filter helps in
PSK31 reception.

I got fldigi set up and VAC and vspMgr configured. When I tested it
using PSK31 I got this spur in the Panafall on transmit.

Flex-3000
Windows 7 64
PowerSDR v1.18.3
Driver Version 3.5.0.7171

What do I do about this extra audio artifact?
