-------------------- Excellent suggestion Stewart! The lower frequencies in my voice are more rough than "low". Unfortunately, I don't have one of those voices that is usually pressed into service for broadcast work. The capacitor technique is a good one. I used it in a couple of tube-type AM rigs over the years. With the K2, I really appreciated the flexibility of the BFO and Filter setup that allowed me to tailor the speech bandpass without resorting to swapping component values. It does leave open the issue of whether some of the low frequency components that are being cut off intentionally by the SSB filter might be triggering the compressor or audio ALC functions, affecting the overall speech amp gain. I seem to have adequate for full output across the spectrum on SSB, so I hadn't looked into it further.
