[Elecraft] K1 build question: T1, turn count method.

[Don Wilhelm]

Paul,

Yes, correct the turns count on T1 and T2 if necessary.
The impedance matching is important for full power output.

You are not the first to miscount the turns on a toroid (adding an extra 
turn).  Remember that a single wire through the core is one turn and a 
full wrap around the core is 2 turns.  That is especially important for 
the toroids in the LPF on the band board.
