Local Noise Generator Found

Did a hunt yesterday as part of the ongoing noise mitigation effort at
the QTH. After powering the Flex 6400 with a battery and laptop on battery power, I started flipping breakers, finally localized the source to the shack(naturally). After unplugging each item in turn, (Modem, Router, Access Point, Monitor, etc) the noise reduced 20dB when I unplugged the USB powered Bluetooth/WiFi speaker. Now 20M shows -110 dB noise floor when 400Hz bandwidth selected. What a difference!

    Any one can print a label and stick it on a device. No way the FCC can check every one of zillions of imported devices.

    Yup, not like it was over 20yrs ago when they had some control on stuff being imported. I remember in the old days my brother had sever RFI, long story short, they went up with a helicopter and found the source a few miles away, it was a clock radio and the 10 people scattered like roaches when they knocked on the door. I have soo much RFI it's not even funny but like they say " you get what u pay for "
