A common question concerning inductors wound on toroid cores is whether a retaining compound should be used to fix the windings in place.
In the case of the cores used in the K2, retaining compounds are not necessary and should not be used. However, this question still comes up and there are cases where retaining compounds are necessary, or at least desirable. I've added a page to my web site showing how to make Q-Dope and presenting measurements for similar coils retained with real GC Q-Dope, my homebrew Q-Dope, beeswax and hot glue. http://www.cliftonlaboratories.com/coil_coating_compounds.htm Jack K8ZOA ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
