Can the Flex Knob be used in a remote setup with a laptop only? IE, not physically at my radio in my house, but want to have the versatility of the Flex Knob while I'm doing it.
YES. It is recognized locally by your laptop. As a matter of fact, even if at home the knob always plugs to a USB port of the PC where SmartSDR software resides.... in your case your laptop. The flex wheel doesn't connect to the 6xxx radio, at least for 6300, 6500 and 6700.
