[Elecraft] Tracking down S9+ noise on 40M

[David Dietrich]

Hi All,

Could someone please explain the proper way to track down RF noise in and around my house?  More often than not, I always have S9+ noise on 40 Meters, making anything but really strong signals (S9+) audible above the noise.  I have only had a few instances where the noise was below S9 on 40.  I know I have to power down the house and then bring it up one circuit at a time with my radio on battery power.  I also know I am supposed to use a handheld AM radio to listen as I walk around the house.  I don't know what I should be listening for, or where to tune on AM to hear what I am supposed to hear.  Now that I am getting back into operating more regularly, I would really like to see where some of this noise is coming from; and reduce or eliminate it if at all possible even if it means shutting something off while I am on the air.
