[Elecraft] KNB2 - odd behavior

[David Zatopek KT5V]

Hi, Vic, thanks for the reply.  I was fairly certainly that the crowd of
large signals had something to do with this, but had never observed this
before.  Probably because my other HF rig's blanker doesn't really "blank"

The K2 blanker has become indispensable in my semi-urban environment.
