Yep, thanks Kelly. I¡¯m asking about the headset out on the MH-34 speaker/mic, which is a 3.5mm mono jack. I just tried adding a filter and that seems to have done the trick. ?Two .33¦Ìf dipped ceramic caps fit neatly into a mono plug shell, and get rid of the thumps without losing much bass from the rest of the audio.
Thanks!
