Hey guys, I just got my feed up and running, however I noticed some really bad feedback. Through process of elimination I have figured out that my scanner being plugged in is the cause. Using batteries I still have some feedback but it is much better. As soon as I plug in the AC adapter the feedback gets 3x worse. Is there any way I can fix this? I'm using a Radio Shack pro 96, hooked up using an audio wire from headphone jack to my computers line in. Scannercast software.
