[Elecraft] K2 Toroids Latest?

[W3FPR - Don Wilhelm]

Deni,

T7 is the only transformer that will make any difference.  If it is wound
with a 13:3 turns ratio it can be rewound with a 20:5 ratio for a better
impedance match to the IF filter.

The number of turns on bifilar wound T3 has been reduced in later K2s, but I
have not noticed any difference (including the RF levels on my 'scope) after
changing it on several K2s.

73,
Don W3FPR
