[Lowfer] a thought on coils

[john hoopes]

I find it interesting the different approaches taken to building an
"ultimate coil". The simplest coil I ever encountered was  made by Walt
Glazar, W3WI. His beacon WI was heard all over the East coast as well as the
mid west and it consisted of nothing more than a PVC form with two pi wound
litz sections over a small ferrite rod. Walt was a stickler for efficiency
and if it didn't perform, it didn't stay in his beacon. Ferrite is very
useable if you don't saturate it with too much power provides an easy way to
tune a coil to resonance.

Think outside the box!
