Antenna noise on my 6300

You have now become aware of how noisy the world has become.

Everything from the drive electronics on a variable-speed furnace fan to the circuits built into LED light bulbs is making noise. The harmonics of the pulse-width modulated square waves in these things make those "humps".

Do you remember learning somewhere along the way that a square wave is made up of a fundamental sine wave and an infinite number of its odd-order harmonics?

Well, now you know what that looks like on a spectrum analyzer.

I get a pattern very similar to that from the under cabinet halogen lights in the kitchen. They are powered by an old wall-wart power supply.  It wipes out 160-10 meters.  I haven't had the opportunity to replace it yet.

So sorry you're now "enjoying" all the radio spectrum can offer! I spent over a year obsessively tracking down noise before I called it quits and realized there was some stuff I couldn't clean up (other people's washing machines, pool pumps, plasma TV, etc. KY6LA has a great presentation on cleaning up your own house. A recounting of my experiences is on my QRZ page. There is A LOT you can do. I also found the MFJ noise canceller (phase device) helps with some sources. I think it was Tim who first told me what I call the Flex Paradox - the best and worst thing about a Flex radio is the spectrum display coupled with that awesome receiver. Now you can obsess about noise you never knew about before! And wow, what a difference when you succeed. GOOD LUCK!
