OK, now on behalf of us non-cognoscenti, are you guys saying that the
segmentation of a solonoidal plate choke cannot be wound so as to
avoid resonances at undesired frequencies?
I don't want to waste my time trying to wind a new choke for my amp that
does unhappy things every time I try to use it on 24 MHz if it is a
known fact that
segmentation doesn't work.
Anyone want to guarantee this? :-)
