The very simple noise blankers of the K1 and K2 seem to help only on ignition, motor commutator, and other such similar noise.  These blankers seem completely ineffective on all of the various types of power line noise I've encountered, unlike the more sophisticated blankers in most other rigs produced in the past 25 years.   The blankers in my ancient 22-year-old TS-430 and 11-year-old TS-50 work wonders in comparison.

Maybe it's time for a re-design of the Elecraft blanker system.
