Well let's get out the calculator....... Assume 3.5mh at 185.3k and that
gives an XL of ~4 kohms. The Q would be 4x10^3/12 = 333 which I think is
good for a #14 coil wound with house wire on a PVC form or paint bucket.
Bill B used to get the real good numbers with Litz on specially cut PVC
forms and/or basket weaves but I'll check on his Qs using solid wire, later,
when I get home.
