The previously referenced <http://devices.natetrue.com/wiviz/> shows you one way to do it and an URL to the Ubiquiti SDK was provided, enabling you to see the source code. You can write code that emulates a very fast operator at a keyboard and stuff the operating frequency you have decided is best. best regards/ldv -- Larry Vaden, CoFounder Internet Texoma, Inc.
