Joe has one, Markus had one, i think M0FMT has one and others. Should i also buy one? Sorry, OT stuff. Anyway, can you tell me her name?

Another one: The coil becomes warm and this leads to a higher coil diameter and thus a larger L. Then the resonance frequency drops and the phase will change. But this will not lower the resistive component, usually. 73, Stefan
