The application is concerned with RF safety and Field strength at neighboring properties. At 1/10 watt ERP thats a bit of a joke but I guess we have to do the calculations. How to demonstrate technical competence? This I can only assume is to describe the proposed station and its technical parameters from exciter type through to antenna. In my case crystal heterodyne method as a start. And I guess the method to measure ERP? Or can the antenna efficiency be assumed from calculations? Any way I have made a stab at all those questions and we will see what the result is. Best 73 Pete M0fmt.
