I am hearing it in Memphis, TN. It is S1 on my TS-850S which is my noise floor today. I can't get it to come up or change in strength by rotating my F12 C3E. A lot of this stuff has been traced to the AWACs (airborne early warning) aircraft that are continually operating over the US with VERY high powered radars, etc. these days. Steve, N4JQQ
