Dual Wire Wind? (Alternative to tapping/splitting)

Means that a higher C lowers the Q-factor.

But more important than Q is that a large C means a low resonant frequency and thus poor HF response.

Thanks Roland.

Already discussed and pointed out repeatedly is the additional capacitace caused by the unused portion of a coil. My question now is whether that still applies if BOTH ends of the usuaed portion of the coil are switched open. With no landing place for any semiconductivity I wouldn't think so. It seems to me that this common problem might be solved with a little more switching circuitry effort?
