Is this legal?

An AM station is about to become available. It has a 250 watt translator that is licensed for 25 feet above ground level at the same coordinates as the series feed AM tower according to the FCC online data base.

My concern is the FM antenna is actually on a wooden utility pole erected about 75 feet from the tower. Is this going to be an issue if a FCC person actually does a check?
 
Um, yes. 75 feet is more than is allowed in coordinate variation. It should have the license corrected to the proper coordinates.
 
They actually have a good "FM" site. 200 feet above average terrain. About 20 miles 60 db not counting null in the pattern which is about 10 miles

0.25KW at 225 HAAT should give you a 60 dbu circle about half that (12.2 miles) according to fcc.gov calculator.
What power does the AM operate with? How much coverage can you actually legally get with the translator?

As I said the site is really good for FM. A nice "flat top" hill.

Depends where you are. In. The Coachella Valley 10 kw on 1140 barely gets a usable signal for 15 miles.

I thought the translator 60 dbu had to stay within the host AM's 2 mv contour. I was thinking the 25 mile rule was in regard to main studio location.
As usual...I may be wrong.
