Simulcasting on the same frequency

[Dib9@aol.com]

Maybe some of you who are more technically oriented can answer this question:

What would happen if two AM stations in close proximity at the same frequency
simulcasted?  Would it improve the reach of the stations?  Would they still
cause interference on the margins?  

For example, WPOR in Portland is on 1490 and there is a station in Augusta,
about sixty miles north, on 1490.  The signals nearly overlap during the day.
 What would happen if they were hooked together and ran the same programming?
 A similiar situation exists at 1400 with WIDE Biddeford and WTVL Waterville.
