Hello reflectees;

Here's an interesting scenario.  While running some antenna tests this =
evening on my 4 RX antennas I noticed the following condition when I =
switched the NB on and off.

While the noise on the dipole is running around S6, NR is OFF, AGC =
setting is manual and set at 3 o'clock position, NB is OFF..  Upon =
switching the NB ON, the noise rose to S9.

I looked and examined this several times and saw the same thing every =
time.  Since the first 18 menu settings either control or effect the =
receive portions and the DSP settings, I will give those menu settings =
at this time.

2 =3D 7
3 =3D 12
4 =3D 14
5 =3D 8
6 =3D 1
7 =3D 1
8 =3D off
9 =3D on
10 =3D off
11 =3D off
12 =3D on
13 =3D on
14 =3D 2
15 =3D 17
16 =3D 0
17 =3D 0
18 =3D on

Has anyone else seen this scenario before?   Can anyone explain what is =
happening?

I thought the NB was supposed to reduce the noise level---not raise it.

I seem to have a constant noise level of S6-S9 =
24/7/365..................I am currently working with the local power =
company to resolve the noise problem.  All of my detection sources, =
checks and tests point to a main power line pole directly in front of =
the home with a pole pig/transformer on it.  15 feet away from the pole =
in a 360=B0 parimeter there is no sign of noise on an AM receiver.  Get =
directly underneath the transformer 3' from the pole and rotate in a =
360=B0 circle and the noise is identical to that on the 870.  The power =
company doesn't think or feel that this is where the noise is comming =
from.

Anyone with any ideas???????????????????????
