What is the easiest way to measure the inductance and Q of a coil or transformer primary at a given frequency? For example, if I want to wind a 29 uH inductor on a surplus ferrite core and have a signal source for the desired frequency how would I measure the inductance so that I could add or subtract turns to hit the 29 uH? I know this must be easy, but right now it seems to evade me. Thanks, Ron
