[Elecraft] 40m low power

[Don Wilhelm]

Ian,

My first guess is that you wound an extra turn on the toroids.  Count 
the number of times the wire passes through the center of the core.
A straight wire through the core is one turn, a full wrap around the 
core is 2 turns.  If you did not realize that when winding the toroids, 
it is likely that you have added an extra turn.
