I need to loosen 
the coupling some day and do some full power tests at 120 bps - maybe even 
add some additional primary capacitance.

Hi, all... 
      I had an idea. If one had, say, 15 turns for their pri., and  tapped 
it at 10, how about this: Build a 20-turn primary, tap it at 5 turns from the 
outside(15) and put the inner-tap at five. Would you then be able to change 
the coupling by mivung the inner (and the outer) tap? It would look kind of 
like this: 

                   
     | | | | .| | | | | | | | | | | .| | | | |  O <- secondary 
            ^                   ^ 
    outer-tap            inner tap 

The only thing I see wrong with this is, since the pri is metal (of coarse) 
it will still conduct the magnetism to the same coupling as a normal pri. 
would... 
I'm starting to confuse myslef now :-D
