[BC] 50 kW DA Coverage

[Robert Meuser]

Willie:

The old WMCA CP first issued in 1992 is no longer in the FCC database. But 
looking at the existing 3 tower day pattern, I see no need for a pencil beam. 
The existing site in the Newark Bay would not have sustained the additional 
towers.  I suspect that re-location in the area while dealing with Newark 
Airport restrictions probably made the project too difficult and/or expensive.

Pulling the TX site further west and drastically increasing ERP would have added 
population to their coverage. I would suspect at first blink, they would have 
had a pattern similar to KMJ. approx 500 KW ERP at 570 certainly would have been 
impressive.

  The CP was extended several times, all under Salem. Someone must have thought 
it was a good  idea.

Many highly directional stations take advantage of distance and high ground 
conductivity to put more population in the main beam at the expense of rural and 
open areas.
