[Elecraft] RX IQ sound card problems KX3

[Don Wilhelm]

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.
