That should probably be restated as will never be as dirty as Yaesu, Kenwood or Icom since the ALC circuits all three radios actually work by overdriving the final amplifiers BEFORE they start to produce any ALC action. In effect, their final amplifiers act like an unfiltered RF clipper. That said, the K3 is certainly capable of providing significant "punch" if adjusted properly. With nearly any mic adjust the lower two bands in the K3 equalizer to the minimum and adjust the top three for the amount of high frequency boost desired (EQ is before the clipping function, if I remember correctly so it sets the "balance" of highs and lows). The HC-4 will need less high frequency boost than an HC-5 which needs less boost than the new HC-6. Adjust the mic gain until you see 5 to 6 bars of ALC action and then add compression until you see 10 to 15 dB indicated on the COMP display (setting between 20 and 30). Control power output with the power control and adjust TXG VCE for +5. to +1.5 dB to bring the peak power on SSB (using a pulser) to the same level as peaks on CW (using CW dots).
