Carlos,

The spot and keyer sidetone are not in the same path as receive.
I suspect that you need a better IF filter (CAL FIL) than what is
provided in the manual.

You can download Spectrogram from my website www.w3fpr.com (look near
the bottom of the home page for the links) to give you a visual picture
of the filter passband position and filter width.
Tom Hammond N0SS (SK) created a document that will allow you to use
Spectrogram 5.17 to align your K2 filters.  It is available at
http://www.mmccs.com/mmarc/n0ss/k2_filters_using_gram_v5r17.pdf.
