John,
It sounds like you need to adjust the BFO settings for the FL1 SSB
filter. You can do that in receive.
It is best if you do that using a visual aid like an audio spectrum
analyzer to be able to see the position of the filter passband in the
audio spectrum. Spectrogram is one such analyzer - it runs on your
computer and soundcard. Non-Windows folks will have to find some other
program.
To see how to set up and use Spectrogram 5.17 download the .pdf at
http://www.mmccs.com/mmarc/n0ss/k2_filters_using_gram_v5r17.pdf.
You can download Spectrogram from my website www.w3fpr.com. On the home
page, scroll near the bottom to find the links. Both versions 5.17 and
16 are there.

Hello Elecraft Community,
I have recently built the K2/10 and have enjoyed listening to the receiver. I
have more recently added the KSB2 SSB adapter and have noticed my voice is
either very high-pitched or low-pitched on an external receiver while using a
50-ohm dummy load.
After spending some time on the issue of SSB voice on transmit, I realized that
if I mistune the K2 on transmit that my voice would appear to sound normal with
no humming on an external receiver. The following are examples:
