[Skimmertalk] Image frequencies falsely reported using QS1R

[Bob Wilson, N6TV]

Today my Skimmer Server 1.3 is reporting stations on both the "right"
frequency, and the *wrong* frequency, due to some type of signal image
issue that I haven't noticed before:

This is using a QS1R attached to a Pixel RF-Pro1A 8' high, with a Norton
pre-amp; I don't think it's a signal overload issue.

The only thing that has changed recently is that I'm using Aggregator
version 2.4, though I don't think that has anything to do with it.  I
selected my normal "Contest Rotation" .ini file.  Maybe I need to limit the
CW range to frequencies below 28.150 in the that .ini file?  Or lower the
"LO" frequency?

Has anyone else seen and cured this problem when using a QS1R with Skimmer
Server set for 192 kHz bandwidth on 80 - 10m?
