Re: [TCML] Helical Primary

[bartb <bartb@xxxxxxxxxxxxxxxx>]

Hi Paul,

As Dan mentioned, MANDK is a fine program for looking at a series of 
geometry and coupling. However, coupling will be dependent on where you 
need to tune the primary (which affects physical geometry). So it's best 
I think to design the coil with all the components (tank cap included) 
and then determine the primary geometry as part of that design. Javatc 
is available for that type of design.

The problem is that I want to make the primary coil a helical coil, but I don't want to end up over-coupling it. So, can anyone advise me on the physical dimension I need to make the primary coil?
