The fact that you were using an audio spectrum analyzer of some sort
made my answer easy to state. The K1 manual does not make any
assumptions about tools like an audio spectrum analyzer, so must resort
to telling you to peak the BFO at your chosen sidetone pitch (or other
words meaning the same thing), and do likewise with the TX offset.
Since you said you were using an audio spectrum analyzer already, you
provided information that was already halfway to the goal.
BTW, if anyone wants an audio spectrum analyzer to load onto their
Windows PC, I have copies of Spectrogram (both freeware versions 5.17
and 16) local to my website available for download at www.w3fpr.com.
Look for the links near the bottom of the opening page. Since those are
copies local to my website, be assured that they have been scanned many
times and are free of viruses (I have reports of other sources of
Spectrogram may be contaminated. Norton may object because it does not
have enough experience with those downloads, but rest assured, they are
clean and you can ignore the Norton warnings.
SpectrumLab and others will suffice just as well, but I like the
dedicated "scope" display of Spectrogram.
