Jimmy, For aligning the CW filters, it is adequate to just turn the DSP off, but when aligning the SSB filters - particularly if one has widened the bandpass to 2.2 or 2.5 ala the KI6WX mods, I prefer to remove the DSP completely and put the 2 jumpers in place to restore the audio path. The DSP has the low pass filter in place all the time and will cut off the high frequency end of the Spectrogram display with these wider filters.
If you look only for the low frequency corner of the bandpass, you can likely get away with leaving the KDSP2 installed, but if this is your first time through the Spectrgram routine, I advise you to temporarily remove it. BTW, the same caution applies if one has the KAF2 installed too - it also has a low pass filter. 73, Don W3FPR "Life is what happens when you are making other plans" (John Lennon wrote it in a book, Mike Cross used it in a song - I don't know who was first) ----- Original Message ----- > When using Spectrogram to align the K2 filters do I need to set the DSP > filter to filter 1 or turn it off? > Jimmy, AE4DT > _______________________________________________ Elecraft mailing list Post to: [email protected] http://mailman.qth.net/mailman/listinfo/elecraft You must subscribe to post.
