Re: Elecraft Digest, Vol 74, Issue 16

AMFMTV
Regarding the WKYC, Cleveland TV transmitter:

I can see the WKYC tower from my front window, about 2 miles from my QTH.  WKYC ended digital channel 2 transmission on June 12, 2009.  I was standing next to the digital channel 2 transmitter when they pulled the big switch.  Until then, because of my proximity to their tower, most of 6 meters was hash.  They had an interim 10kw ERP on RF channel 2.  With the sunset of analog TV, WKYC moved to RF channel 15, and 6 meters was quieter that it had been for several years at my home.

There are a few digital RF channel 2 transmitters still operating, and anyone within several miles of them will have some hash on the upper end of 6 meters.  Even though the out of band digital hash needs to be down some 80 db, 80 db down from 10kw ERP from an antenna 1000 feet above average terrain is still plenty of signal to wipe out weak signals on 6.
