The K3 provides a way to adjust speech controls and ALC level off-air.
(Technical note: The reason this is possible is that the K3's fast ALC
is established in the DSP. This means the K3's first-I.F. crystal
filters can be used in TX mode to ensure that dynamic ALC responses
are band-limited. This prevents the kind of splatter often heard from
rigs that apply fast ALC in hardware, after the crystal filter. This
technique also allows the DSP to provide very effective, very clean
speech . . .
