Good question. The answer is no, there is not. SmartSDR for Windows is the "client" part of the radio client/server architecture. The FLEX-6000 is the server. Since both parts work together in tandem, the client will not operate with out a server to connect to.
We may be able to emulate a server at some point in the future to allow for a demo mode, but right now is is not on the development horizon.
