When out of Joy, try Dawn. ;) Seriously, there has to be a new source of that noise in or near your house/station. I have seen trickle chargers, battery tenders, wall warts, etc. that caused horrendous noise. I personally found a wall wart on the old router that went bad (it was >6 years old) and drove me nuts with noise. Of course, it was the last thing I checked.
Outside the building, there could be a bad power line or transformer. Best of luck finding the source; please let us know how it goes. 73, Jerry On May 3, 2013 12:34 PM, "Marty" <w8ak...@gmail.com> wrote: > > I accidentially discovered this problem while working some Dx. > > My noise level was at –140 when I decided to change bands. Upon changing bands, I went to tune the antenna.
