Hello �Crafters. DK7FC, who has no Internet for the moment, has just finished his cw-only K2 SerNo somewhat > 3000. He reports, that he can NOT align the CW-Filters. FL1 is ok, but he can�t find a setting for FL2 through FL4 to hear the beat-tone. Where should he start to look? I will pass any suggestion to him via 144Mhz. Thank you . Martin
