Well, one of the last remaining issues continued to be birdies, with spacing varying depending upon band so sometimes they might be 20-30 Khz apart, other times more and also more frequent. Tonight, I discovered that is from the other router I use.? For my internet, I use a cat5 cable from the router to the laptop.? When I unplugged the cable, the birdies disappeared.? Now I ask, what can be done?? I guess I could always unplug it when accessing my SDR from the laptop remotely, but was hoping for something better.? I tried cat6 cable.? The tones were not as strong but still present.? Then I placed ferrite cores around the cable and didn't seem to make much difference, then tried the switching supply feeding the router.? No effect either.
