[Elecraft] Noise with KUSB

[Rick Tavan N6XI]

You've found the noise source; now find a way to eliminate or replace it.
Does your USB hub use a wall-wart power supply? Some of these are noisy.
Maybe you have another USB port on your computer to which you can connect
the KUSB directly, bypassing the hub? Also, some USB hubs work OK with the
PS disconnected, depending on the current demands of attached devices.
