Tabb.
You are seeing images. That is a result of either imbalance in your
soundcard gain settings for the I and Q settings or a failure ot the
application to adjust for those images. If you are using NaP3 as your
application, there are steps you can take to detect and cancel the
images - tune to a strong signal and the cancellation process is automatic.
I refer you to the archives on LP-Pan Yahoo group for more information.
Most of the information on NaP3 and PowerSDR-IF can be found there.

Hey I got it figured out just needed a isolator between the radio and computer.
I do have one question on the scope I see the same signals up and down from the
center frequency. One in upper side band and one in lower side band. Do I have
a setting wrong in the option menu?
