Title: RF Noise Source Found
Post by: RadioRay on November 08, 2014, 05:09:18 PM
I've had a source of local noise, but never really tried to track it. However, today I put-up a 'quickie' vee-beam pointed at a friend of mine and when I would switch form the Delta loop to the vee-beam, the noise jumped from S2 to S8!  Several things crossed my mind (Martinis, dancing, becoming Emperor of Earth, a new KX3!!!) however, there was something else - a major difference in the two antennas: location.

1.  The vee-beam terminated near power lines.

2.  The vee-beam passed over the house.

3.  The Delta loop is away from the house and the powerlines.


I decided that it would be better to test the house first.  Seems that the local power company thinks poorly of people who drop the power grid to check for radio frequency interference - at least that's my impression.  So, I tuned to an open spot on a noisy band and began turning breakers off.  When I reached the living room breaker, the RF noise went from S8 to S-unreadable on the meter.  Aaaaah!  Long story short, the family computer system is served by that breaker.  I powered back ON and the noise came back.  It turned out to be the Linksys wifi box, making all that noise!

Now, my RF noise level is basically zero, because it's not merely the remoteness of the old antenna system from the house helping, but the source is DEAD, DEAD, DEAD!


Reminds me of a merry tune from 'How The Wizard of Oz SHOULD Have Ended':

Wrong rifle, but yeah, that pretty much sums up my feelings towards Hollywood in general. Those stupid horror movies with the psycho chasing the group of stranded vacationers through the woods and killing them one by one drive me up the wall.......... my god, does no one in Hollywood land carry a gun other than action heroes and bad guys?!?! Shoot the inbred 6 toed son of a bitch!! 8)

Rant mode off.

KK0G - True - 'horror movies' would be short and with a happy ending 'no repeat offenders'.    :)

Empty - Oh, I know better than that.  I'll dig through my stuff and find another wifi box to put in it's place. In the meantime, I'll plug it in when my lovely and talented Wife  :-*  is home.
