[Elecraft] Filter problems

[Keith Hamilton]

I have a K2 with only the ksb2 option installed.

I have downloaded Spectrogram and aligned my filters with sucess.

When I switch to filters FL2,3 and 4 in CW mode the speaker audio
drops by 90%.

I can still hear the cw signal in the speaker, and the tone remains very
close
to the same on all 4 filters but on every filter setting except OPT1 the
audio
output drops drastically (to an unusable level)

Help?
