I received this email tonight and thought it might be of interest to those
of you with RX noise troubles. Operation video as posted on YouTube.

DXE-NCC-1 video with Kenwood TS-990S
https://www.youtube.com/watch?v=6MU7jhCPhaM&feature=youtu.be
Hear Super Rare DX Station KN1 on my TS-990S with New DXE-NCC-1 Noise Phase
Nuller Reduces my Power Zap Noise from S9+10 to S3 ( No Distortion - Just
use NR1 on TS-990S ) Noise a my QTH terrible, so I had take action with
added a Noise Nuller for my TS-990S.
Note, it cleans up BandScope & Waterfall greatly !!
Also, Thank You, Kenwood for Version 1.09 Firmware, The Screen Scrolling
feature is great !
My Main Antenna is a Hex Beam, The Noise Sense Antenna is a vertical piece
of 4 foot wire using a 1:9 balun ( 50 ohm to 450 ohm ) which is broadband
from 40 meters to 6 meters and will not interfere with my Main Signals from
my Hex Beam.
Please Note :
Noise Antenna must hear noise Louder than your Main Antenna to get the Noise
Null. So it is important to put Noise Source Antenna as close to the
Noise Source as possible. Works also great with Plasma TV Noise from my
neighbor as well.
Great Solution !!
Now I can Work DX, including K1N !!!
Had to live with this S9+10 Noise on my TS-990S constantly until I found
the DXC-NCC-1 solution to mate up with my TS-990S !
