[Elecraft] Couple questions about K2

[Don Wilhelm]

Alexey,

That is a very old mod (2003) and was one of the experimental things 
done at that time.
Since then, the T7 winding ratio has been changed and the specs on the 
IF filter crystals have been modified.
Currently I do not believe there is any benefit in applying that mod to 
a K2.  If you have a very old K2, simply change the T7 winding to the 
ratio given in the current K2 manual.

73,
Don W3FPR
