Tower cranked down and lowered, antenna re-alignment completed. Tower returned (manually) to upright, then elevated to full height.
During the 48 hours of this project, I noted that my across the street neighbors had packed and moved out of state. They will be missed!
Imagine my surprise to return the gateway to operation and find that a broad S9+40 noise had disappeared. I suspect one of the items packed was a large plasma TV
Tower back to normal height and antennas in service.
Made a change to scanned frequency for 80M channel - moved to high end of ACDS window to avoid a severe local noise issue still under diagnosis.
Not in my house! HA HA I'll get you, sucker!!
