Does my core suitable for RF choke @2014/6/25
first time i encounter the core failure because unsuitable for use as RFC in RF choke: dig SRF project. for long time i want to find some way to identify a un-known core's capability.
this experience given me hint to evaluate if the core is suitable for choke, just built a oscillator like this one to to check it.
