I share a tower site with other hams and received a call about a 12v ipCam power supply that had been tracked down as the cause of HF interference. They were kind enough to swap out the power supply with a better one :) , and I avoided a drive up while being out of state :) . This power supply was 4A @ 12vdc rated that came with one of these low cost China made ipCams. While the price was right, the old saying, "you get what you pay for" applies. Although, we've been very happy with the ipCam itself. I make this post in case others are able to avoid a similar situation and may be causing interference unknowingly.
