[Elecraft] K2 A-to-B upgrade question (RFC11)

[BobDobson@aol.com]

Page 6 of the Rev C version of the document "Upgrading the Elecraft K2 
to Revision B" calls for the replacement of RFC11 with a user-wound
toroid.

Were one to wind this toroid in the customary fashion with about 3/4
of its circumference covered with windings, mounting it on the underside
of the board, in my opinion, makes it (potentially) mechanically unstable.  
With gravity, earthquakes, mobile operation, etc., I'd think the toroid might
eventually make contact with the sheet metal beneath.  

I see three ways around this: (1) Ignore it because Bob is clearly worrying
too much, (2) wind the totoid with about 50% coverage so when you solder
 it in place it will be more stable, or (3) anchor the toroid in place with 
some
silicone rubber sealant.

Inputs from all are welcome as always.

73,
