[Elecraft] K2 NB testing

Tue Nov 11 17:08:04 2003

Hehehehe...Funny you mentioned the mixer Rod! On our last camping trip to
the desert, one of the guys brought an inverter and a blender to make
Margaritas for everyone. One time when they were firing it up, I was on 20
meters with the K1 and I'm here to tell you that the mixer makes a bunch of
loud impulse noise! The NB in the K1 took care of it really well though. The
NB in the K1 and K2 did a great job at the house in Burbank, CA getting rid
of various types of powerline noise and other man made noise emmisions.
Burbank isn't exactly an RF friendly environment. Hopefully the Santa Monica
area will be a bit quieter...
