Unfortunately, that idea would be totally illegal and against FCC rules. An AM station may utilize an FM translator only within the daytime pattern of the AM station's primary service contour. The 103.3 Entercom translator facility downtown exceeds the area KRIZ or KZIZ's primary 1mv/meter contour. Mr. Chris Bennett, owner of the Z twins would be wise to make a deal with the KGHO 92.9 MHz translator if that was a strategy worth pursuing.
In any event, I agree that the 103.3 translator should be rebroadcasting an HD channel of Entercom's choosing. That is perfectly legal.
So.. We dont measure AM signal quality in dbu, but mv/metre instead?
