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

Tue Jan 7 22:00:00 2003

I used a little dab of hot glue to secure mine... The instructions also call
out to install an insulator on the inside of the bottom cover...
I wound mine with the regular 85% of wire covering the torroid.

73 and good luck!

P.S. You most likely worry to much Bob.... :)
