If you have the K2/100, remove the KI6WX mod - without the KPA100, it
makes no difference.
Make certain the SSB FL1 filter is set to OP1.
Check the position of the OP1 filter passband with Spectrogram . The
low frequency 'knee' of the passband should be close to 300 Hz.

Franki,
Were you able to fix your SSB audio problem?
One area you might want to check is what you have the SSB filter offset
set for. If you have the 2.8 kHz filter, this offset should be zero. If
it is the 2.7 kHz filter, this offset is usually in the -0.80 to -.90 ,
with most set for -.85.
Is there any K3 user that can give me some advice?
I don't do SSB very often and it's the first time I try this mode with the

It is important where you set the audio passband. Normally, there is no

Using Spectrogram to set the SSB filters, I normally recommend that you

Since you mentioned a lack of highs, I doubt that the low-frequency

What is more important is the place the low frequency corner of the FL1

When you cite the -3 to 6dB point, do you mean to say -3 to -6dB? That
