??k??b{ selection guide for standard coils (1) alternate use of a brass core will increase the usable frequency range of any specific coil form. however, inductance is reduced. these cores may also be substituted for ferrite as a means of lowering q. (2) minimum inductance core position (7 1 / 2 t to 10 1 / 2 t) 2 turns off from top of bobbin or metal can. (3) q measured with a q meter. (4) inductance measured with 4191a (agilent) or eqivalent...the values reference only.
