Hi Brian I would also like to know the answer as well.
Its a feature that works well on the Icom PRO radios. You can narrow the TX bandwidth and produce very penetrating audio without playing around all day with mic EQ settings. In fact most cheap mics can be made to sound pretty decent when transmitting through a narrow bandwidth filter. I am surprised that variable TX bandwidth is not a feature on the K3 yet. Another feature that works well is the Kenwood High Boost. This feature is found on the TS870S, TS850S and the TS480. This high boost can brighten most microphones without playing with a TX EQ all day. Its very effective on 75 meters on SSB for cutting through QRN. It certainly sounds better than the excessive bass and ESSB audio that people torture your ears with. ESSB station who call people in the DX window with the excessive bassy audio should be put up against the wall and shot for torturing other people. I have found the K3's DSP filter on 1.5KHZ bandwidth to be very effective. We just need people that use communications quality audio for this filter bandwidth. The Heil HC4 and HC5 are fantastic microphones for DX work on the K3.
