When I turn on NR the audio noise level goes down. When a SSB signal is received the audio peaks. I have my RX EQ set flat. In these peaks there are resonances in my internal speaker (if I use it) as well as my two external speakers that plainly makes noise reduction unpleasant. It can be minimally tolerated at F-1-1 level with speakers. It is somewhat more tolerable with a good headset. Part of the problem may be in speaker response, but I also think a big part of the problem is in the noise reduction algorythms. If noise reduction is not recommended with reduced bandwidth in CW, and unpleasant artifacts occur in SSB; then I find NR to be useless. I hope the discussion of white noise and pink noise will lead to something that will improve the noise reduction function in the K3. Roy Morris W4WFB
