When I tune my K2 in a carrier ( all HF bands excl. 160 mtrs ) I notice the K2 SSB setting has an over 10 dB worse s/n. I really mean worse s/n, no difference in audio ( gain ). My calibrated HP 3335A generates the carriers. My calibrated HP 8568B spectrum analyzer shows the the audio output S/N.
I also varied in numerous combinations the K2's IF and LF gain pots. I tuned both SSB and CW for maximum signal strength ( not for the same pitch.). I guess this does exclude possible non matching filter- and/or bfo alignments. I used the same filterwidths for SSB and CW. The S-meter shows no difference between SSB en CW ( I varied the carrier all over S1 until 9+20 ). What could be on ?
