It is unfortunate they didn't see the value of reworking the old 
86th Street plant in the late 50's because the move to the 
Whitestown plant was already in the planning stages. 
Because 86th St used open wire the nite DA could not be 
stabilized at the old plant for 50 kW DA-2 although 
considerable testing was done at 50 on the old nite
array. Later, when they built the current plant at 
Whitestown in the the early 60's opportunity for 
50 nite was gone.

The coverage with 10 from Whitestown is good over 
most of the Indy metro provided the array is set up 
as designed, but that seems to present a compliance 
problem with the 042 augmentation. Thus, they seem
frequently to distort they pattern to keep that one in
limits which does compromise the coverage in the 
NE sector of the metro.

Adjusted ERP is 50 at that HAAT, thus it is a full Class B
and with the terrain, HAAT is worth more than ERP here,
as in most places.

BTW IIRC this station was originally CP'd as WIBC-FM
back in the day, but went on the air as WNAP.

Sorry, NOT! COL is Shelbyville, but Tx is in Indy. In this case it is
the COL that is a rim-shot. <g>  Also, ERP+HAAT equates to
full Class B.

This is the former WTLC-FM that first was WAVI "back in the day"
