Jim,

Did you power down the battery backup for in-house systems such as your security system and cable modem and routers?

Subject: Topband: RFI - Lots of it

Greetings,Last Fall we moved into a new location.  This Summer I spent a lot of time and effort putting up an Inverted L and radial system.  Now after tuning, etc. completed I have what appears to be power line noise, source unknown at this time.  I threw the main in our home and noise still remained.  The closer I get to the power lines or the antenna system the louder it gets.  As I jump in freq., the higher the band the less noise.  I have a portable receiver that is capable of rx on the ham bands.  As it sits right now 160 is just about out of the question.  Rig is a ft1000mp mk5 field and the NB does do a good on the noise but also on the weak signals.  This is the first location in 35 years that I've run into this.  I don't have much faith at this point in the power company finding the source but will call them this week.  Any ideas would be greatly appreciated and also wondering about Noise Phasing with MFJ-1025.  I read w8ji article on it but not sure if it would help on noise of this magnitude.Regards,jim/k2hn
