[Elecraft] K2 S/N 3105 on the air -- crystal filter curves

[Thomas Martin]

Hello,
just wanted to thank the list and elecraft support for the help during 
assembly of K2 S/N 3105 (Rev. B).
It is on the air since January 6, 2003 now and about 50 successfull QSOs 
have been made.

For those interested in I recorded the CW crystal filter curves for the 
default bandwidth settings using Spectrogram 7.2. K2's AGC and PREAMP have 
been off during the measurement and I used Tom Hammond's (N0SS) noise 
source.
The frequency marker is set at 607Hz which corresponds to the measured 
sidetone pitch for the setting "ST_P=0.60" at this K2. A 170kB ZIP-file 
containing 8 JPEG-pictures (CW normal/reverse | 1500/700/400/100Hz) may be 
downloaded here:
