Hey Guys, Well, I finally got a chance to align the filters in the K2 using Spectrogram and the mini-module noise generator. I followed the various published recommendations and did the adjustment by centering the passband around 600 Hz for all 4 CW filters. For the SSB filters, I adjusted for a passband between 300 and 2400 Hz (more or less). Results on CW were a bit off. As I stepped from CW wide to CW narrow the perceived center frequency of the background noise would shift. I went back to Spectrogram and redid the alignment with the X axis set to log rather than linear. After that, the perceived center frequency sounds pretty much the same at all 4 bandwidths. Based on my experience, the log scale is the right one to use if you want the filters to sound right. - Keith - _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
