1. A method of operation of a dynamic spectrum access (DSA) device, said method comprising:

  • while operating in a first mode, selecting an initial startup operating channel frequency of the dynamic spectrum access device;

    subsequent to selecting the initial startup operating channel frequency, entering a channel maintenance mode in which a plurality of communications are exchanged between the DSA device and at least one remote DSA device, at least one of the plurality of communications comprising an indication of the radio frequency environment in the region of a device sending the communication;

    subsequent to selecting the initial startup operating channel frequency;

    detecting a non-cooperative radio operating on the initial startup operating channel frequency; and

    responsive to detecting the non-cooperative radio operating on the initial startup operating frequency, entering a channel switching mode in which a new operating channel frequency is selected for use by the DSA device based at least in part upon the indication of the radio frequency environment.
