[Elecraft] Re: Updated Version of Elecraft Keying Mod

[Ken Wagner]

G'morning all:

I installed the Elecraft Keying Mod in #3756 with the 180K resistor. 
Shortly after that I finished assembly of #4181 with the 270K resistor 
provided with the K2.

Looking at the keying envelope on a not-too-good o'scope, I can clearly see 
the difference in the leading edge shape between the two K2s. Any trailing 
edge differences were not so noticable. However, limited and unscientific 
on-the-air testing produces no discernable difference. Both reportedly 
produce clean and crisp CW notes and no clicks detected.

73,
