Roland, It is most likely a filter alignment problem, but I will reserve final judgement until you answer some questions about how you are operating.
Did you do your filter alignment with Spectrogram? If not, the visual display of the filter passbands makes alignment a snap, but besides, if you just set them 'by ear', it is difficult to find the filter center, so you may be off quite a bit. Second, were you listening with any filter other than FL1? If the filters are aligned, this is not a problem, but if not aligned, that could be explaination of your problem. Try using FL1 for both transmit and receive and see if your listen frequency is not also your transmit frequency - if it is not, then you have something other than a filter alignment problem. Don't forget to take into account the fact that the K2 display is offset on receive by the amount of your set sidetone pitch, so the frequency on the K2 display should be your transmit frequency. For this reason, it is important to listen to a signal at the same audio pitch as your sidetone pitch. The K2 will indicate the carrier frequency of the signal you are listening to provided you are properly tuned to zero-beat (same pitch as your sidetone). Also, make certain that you have all filters for CW on the same sideband - the BFO frequencies should be somewhat close to those shown in the chart on page 89 of the K2 manual. If you find yours way off, set then initially to the values in the manual and then finish up the alignment with Spetrogram. For further info on the CAL FIL procedure, see my website article on K2 Dial Calibration at http://w3fpr.qrpradio.com - in addition to the info I have provided, I also have links to further info and Tom Hammond's Spectrogram writeups in the article. 73, Don W3FPR > -----Original Message----- > > Hi Tom and others who could help, > You were very helpfull several months ago and I'm hoping you > can help me again.
