Took me just part of an evening to assemble it. Of course I did try the HDSDR software and indeed I have the same hum, which is due to ground loops. I also experienced the total lack of image suppression but that turned out to be a bad contact in the 3.5 mm jack plug at the female end of the adapter cable for 3.5 > 2.5 mm. Thoroughly cleaning the plug solved the problem. Next step will be the isolation. The Softrock mixer has an isolated BNC connector at it's input, therefore did not show this hum problem. 73, Peter - PA0PJE Don Wilhelm schreef: > Tabb. > > You are seeing images.
