It was on 1510. The signal was beamed out to sea.
Very little inland coverage. Interestingly they abandoned
1490 Class IV and opted for the 10kw. Big mistake!
10,000 watts looked nice on the letterhead, kept the
power company happy but poor signal where it was
needed.

Permit me to relate a story. Any relation to present or
past individuals or companies is purely coincidental. I
was asked to inspect and prepare a quotation to rebuild
an AM station with many towers and less than desirable
coverage. The GM brought me to three of the ATU sheds.
I saw car battery clamps on coils and knew this project
would be expensive and time consuming. After looking up
at the third rotatable sampling loop I went to pull down the
thin cord hanging off of it.

The GM told me to leave it alone. It was fishing cord they
used to calibrate the antenna monitor. The engineer would
crank the phasor until the monitor points were in limits
then tug the cord until the antenna monitor read within limits!
It was even nicer when the GM told me to check my pant legs.
For ticks! 

I told the GM they would first need toroidal sampling transformers
and sample line to all the towers. This was already about $8K
without labor. The station elected not to upgrade the array....
