[Elecraft] Boiled toroids <yum>

[Kevin Rock]

In chapter 4, Oscillators and Frequency Synthesizers,  of Experimental Methods in RF Design by Wes Hayward, Rick Campbell, and Bob Larkin there is and interesting 
section on temperature stabilizing inductors.  On page 4.7 it mentions a subtle problem of stress built up in the wires as they are wound.  W7EL's method of stress 
relieving the wire is to boil them!  I find this book to be most informative and will gradually build some of the circuits when time is available to do so. 

Just thought I would pass this along to all you toroid winders out there :)
