[Elecraft] Spectrogram software

[Rich Haendel]

Several of those on the reflector have indicated their use of a Spectrogram to set the filter bandwidths and offsets.  Although my K2 operates fine on SSB, I seem to lose CW signals when selecting narrower bandwidths. Can anyone direct me to where I can download appropriate software and how to use the spectrogram to set the filter bandwidths and offsets correctly ? 

thanks
