[Elecraft] BFO Mod using Toroidal L33 and R116

[Don Wilhelm]

Lee,

R116 is a high value resistor, so it looks electrically like an open circuit
in comparison to the inductor - so no insulation necessary.  I am not the
designer, but I do believe it serves as a mechanical holddown device for
L33, and also provides the leads to the circuit board holes rather than
trying to thread the ultra-thin wire of L33 through the holes - just solder
L33's leads onto the leads of R116 -  much more gentle on one's sanity
index!!!

about R116 and L33 (toroid 41uh).  Should R116's leads be insulated from
L33?  It looks like the R116 sits down over L33 with the leads touching the
coil.  There is no instructions to insulate the leads from the coil...or am
I missing something here?
