The K2's noise blanker likes lots of signal, even when you select low threshold. Sometimes switching the K2's preamp on makes the difference between no "blanking" at all and full noise suppression.
Keep in mind that the blanker suppresses high amplitude, short duration pulses only, such as you hear on 10 meters from unshielded automobile ignition systems or on the lower bands from cheap lamp dimmers. If the noise doesn't make a loud "buzz" sound, it probably won't suppress it. But those noise types that it does suppress, it normally suppresses very, very well if the signals are strong enough.
