Having Fun:
A popular K2 CAL FIL method is using Spectrogram as documented here:
http://www.elecraft.com/Apps/new_fil_docs/k2_ssb_gram.pdfHaving an oscilloscope with a FFT math function, I wondered how it would
do with a newly acquired Elecraft N-Gen. Results: I was able to perform
the FIL adjustment though I would not call it easier than Spectrogram.
I did find a method to fine tune CAL FIL by measuring two points on the
filter curve and adjust for a correct center frequency. Take a look at
the results and filter shape plots here:
