I want to do some experiments placing ferrite beads on the TMP cables that
carry so many signals around the inside of the K3. I can't find the dimensions of the SP060022 connectors on the cables and I don't have a set of calipers to make an accurate measurement. Does anyone know the location of an engineering drawing of this connector?

They're probably Taiko Denki.

<http://www.spectrum-component.com/Vendors/Taiko_Denki/29tmp-S.pdf> This drawing has the dimensions for TMP connectors. However, what are you expecting the ferrite beads to accomplish? There shouldn't be any currents on the outside of the coax cables.

Thanks to those who sent me a link to the drawing.
In response to several queries I received, I agree that there *should not be* any currents flowing on the outsides of the coax cables. As far as I know, that doesn't mean that there *are* no currents on the outsides of the cables. I think that putting ferrites on the some of the cables is a good way to see if there are currents or not. Now that I have a possible source for the connectors, I may make up my own cables and give them a try. That's one of the reasons I love having a radio I built - or, in this case, assembled - myself. It's a great learning vehicle. In response to other queries as to what might go wrong, I can't imagine why putting ferrites on the outside of the coax would affect the signals traveling on the inside of the coax. If someone can illuminate me, I'm all ears.

>shouldn't be any currents on the outside of the coax cables. There are always currents running on the outside of coax cables unless perfectly terminated at both ends which they never are.
