I can understand. Along with ambient conditions I face a number of offending sources. The power company that sends SCADA data down their transmission line never ceases to amaze me. I watch closely and correlate their operation to their interference. The interference changes some but it always coincides with their use. I think it is a matter of older failing equipment. When they shut down their polling I get wide band noise and last sometimes for hours. Their SCADA channels drift a lot in frequency. But the interference comes minutes after they shut down polling. It last for hours. Then also I have neighbors that can offend. I'll just have to work around that. I am not immune to noise where I live. Logically I should be. Moist of my man made noise comes in the low frequencies. :-(
