Is this for voice or cw reception? The consonant sounds in voice, are mainly contained in the 1600 to 3200 Hz range; rolling this range off is likely to reduce voice readability. Are there or will there be mode dependent settings for the receive equalizer? I've tried using an external high/low/bandpass filter with the K3 on cw and it's not beneficial for me but then my hearing is damaged with midrange loss and distortion in one ear as a result of having meniere's disease.
