Noise Blanking section in the K3 Owners Manual says; Rotating VFO A clockwise will turn on the DSP NB, showing DSP t1-1 through DSP t3-7. The first number shows the relative pulse integration time, and the second shows the blanking level. The higher the numbers, the more aggressive the DSP blanking action. Rotating VFO B clockwise will turn on the IF NB, showing IF NARn, IF MEDn, or IF WIDn, where n is 1-7. NAR/MED/WID refers to narrow/ medium/wide blanking pulse widths, and n is the blanking level. Higher n means more aggressive blanking action. Use NAR width when possible to minimize strong-signal interaction effects.
