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.
