Yes.

The only toroid that is in any way critical is T5, regarding which I 
remember very vaguely that I had to squeeze or separate the turns a bit 
to get the VCO voltage in spec.

[Elecraft] RE: Toriod winding questions (Sorry!)

2004-06-25 Thread Nicolas Pike 
Hi,

I have now carefully wound and installed the first few Toroids for my K2.

Vertical Toriods - As I did not want the wire crossing back over the
windings to the mounting holes. I have a bare part of the Toroid (i.e no
wire) where the core sits on the board. Not sure of the percentage, could be
20% bare.

Horizontal Toriods - As I did not want the wire running parallel to the
windings and back to the mounting holes. I have a bare part of the toroid
(i.e no wire) where the core sits on the board. Not sure of the percentage,
could be 20% bare.

I know the manual says 85% as a target. Am I worrying too much? Is it ok /
desirable to have the wire running parallel to the windings, in order to get
fuller spacing around the core? if so, are they secure with the extra
"loose" wire? I have read the toroid page and looked at photos but I have
missed this mounting detail!

Thanks!

Regards
Nicolas
