[Elecraft] SSB adjustment

[Don Wilhelm]

Bruce,

Take a look at my website www.qsl.net/w3fpr article on K2 dial calibration -
Step 3 covers the CAL FIL info for both CW and SSB, and has a number of
links to additional information.  I believe it will answer your questions.
I believe the 'real' key is to align the SSB filters so that the low
frequency -3dB point of the filter bandpass is located at approximately 300
Hz - that seems to work well for the majority of speech frequency patterns.

If you have additional questions about the content of that article, feel
free to e-mail me at (mycallsign)@arrl.net and I will do my best to assist.

73,
Don W3FPR
