Does anyone have any idea what this is?  The antenna jack is connected directly to a dummy load via a 6' coax jumper. If I remove the antenna coax, the signals go away. If I connect a real antenna, these signals are superimposed on the actual signals. They do tend to drift slightly up and down. 6700  - 1.6.17 - Windows 10

Sure looks like a switching power supply to me.
