[Elecraft] K2/10 (S/N 7967) - SSB voice on transmit issue

[Don Wilhelm]

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.

73,
Don W3FPR
