Topband: A 160m Noise problem

[Ed Stallman]

Thanks for  all the reply's

 From the questions I was ask via e-mail , I'm thinking what I have may 
be power line noise ! The power Co. is scheduled  to repair the pole in 
question but the repair doesn't happen as fast as when the meter stops 
turning .
What has me puzzled, why the noise is strongest on 160

Thanks everyone , Ed N5DG
