How many watts is WBWB 96.7 (BLOOMINGTON) running????

Ive heard, and read to seperate answers to this,, Its either 1650 watts, or 3000. It says 3,000 on B-97s website, and ive read both power outputs on multiple different websites, Including an I.U website, talking about sports coverage. Does anyone know for sure whether their running 1650, or 3000 watts?

I imagine it is 1650 watts at 450 feet in the air, which is probably the equivalent to a class A running 3000 watts at 250-300 feet. FCC shows 1.65 kw on their website. Kind of like WFMS runs 17kw at 1000 feet...same as 50kw at 500 feet...they call themselves a 50kw radio station.
 
Engineer "Skip" here..... Sandy Zorn and his managed station (WBWB) is at 96.7 mHZ and operates as a Class "A" FM facility. Their Effective Radiated Power (ERP) is 1,650 watts at 134 meters (or 436.974 feet) Height Above Average Terrain (HAAT)... They are 348 meters (or 1,134.828 feet) Height Above Mean Sea Level... Their center point of radiation is 84 meters (or 273.924 feet) Above Ground Level on the southeast side of Bloomington....... "Philo The Alien Engineer"

S0 they have a 200 foot tower on a hill...that makes them 400 feet or so above average terrain?

Their not really on hill. The Tower is located right in B-97s backyard, and its located at the Junction of HI-WAY 46, and Hi-way 446. Its right close to the College Mall.

(WELL) Im an unemployed Radio Geek, X-DJ, X-Truck Driver, and X-Janitor, and I live in Martinsville, What do you expect? Besides that, Im only 18 miles away from the transmitter, and I get alot of Static on the inside Home Stereo if I dont position my antenna just right. It should come in, way better than that.
 
> > > Engineer "Skip" here..... Artistic studio for 105.1 and 96.7 are technically on a plateau at the junction mentioned... The Height Above Average Terrain is based on a 360 degree radius from the tower and out two miles.... That determines your HAAT... This is all listed at: www.fcc.gov/mb/audio and go to FM QUERY and type in WBWB and also highlight detailed information or click the WBWB calls on the simple information line... This is official license information on the station....
 
BINGO, Bodine!!!

Their authorized power is 1650 watts.

However, their antenna is 134 meters above average terrain, which exceeds the 100 meters normally allowed for Class A stations like WBWB. They are required to reduce power to compensate. I've not done the math, but for an antenna height of 134 meters, 1650 watts sounds about right for the power reduction from the old maximum of 3000. (I would imagine B-97 is saying "3000 watts" because due to the added tower height, their coverage is the same as that of a 3000-watt station at 100 meters)

"old maximum of 3000", because that maximum was increased to 6000 watts a few years ago. Almost all Class A stations were allowed to double their power - but there were a few exceptions. I'm guessing the presence of WAZY in Lafayette on 96.5 is what limits WBWB to the old maximum. Of course, it *could* be that they simply never bothered to apply for the increase...

As for your underlying question... believe it or not, if you're 18 miles from the tower you are NOT in WBWB's interference-protected coverage area. At their power level the protected contour only goes out 14 miles. I don't think it's actually interference that's making your reception noisy, but the signal may not be nearly as strong as you think...
