[Elecraft] Hi current

Dick,

That current is definitely too high (except on 20 meters).
The most common cause for that symptom is the Low Pass Filters.  Do 
count the number of turns on the toroids in the LPF area - count each 
pass of wire through the center of the core as one turn.  I believe you 
will find you have one extra turn on the toroids.  A straight wire 
through the toroid center is one turn, a complete wrap around the core 
is two turns.

73,
