[Elecraft] Filter alignment once again

[Michael Jensen]

Hi Guys





Can someone give and advice on my filter calibration on SSB, if I am on the 
right track.



I have been looking through all the mail on filter calibration and have now 
got it clear, that I will use FL1 only for TX and have focused on getting 
the K2 to sound "good" (a very subjective thing I know). Then FL2-4 used for 
RX.



FL1 are tuned by listening to the TX from K2 on my FT817 and changing the BF 
until the sound are good. (all of this done due to reports I have received 
telling that I sounded very sharp.. In audio that is J. )



FL2-4 have then been tuned based on TX from FT817 listening on K2 RX, to 
make the sound ok. After that the result are checked with spectrogram using 
the N-gen as input.

The result is found in a word in the following location:

No my concern are as I use PSK31 a lot, if I am going to be in trouble using 
FL2-4 as RX filter, when FL1 are used. With the alignment I have tried here.



I seem to have a issue in LSB, where I can not set the BF any lower then 
what it is now, but maybe ok as it sound ok.



This is my second filter calibration. The first was done only using 
spectrogram for all filters.





Thanks in advance
