How did WKMO land a construction permit to move to 107.3? It looks like it's going to be fighting WUHU (107.1) all throughout Hardin, LaRue, and Hart counties-or basically everything between Bowling Green and Elizabethtown.

WUHU/WKMO

Not sure how an A to A spacing applies south of the river, but here in Indiana, A's on adjacent channels need about 40 mile separation. To me, that's not enough, but then having two A's on the same channel at 65-71 miles is too close as well. We have a 104.9 in Columbus and a 105.1 that serves Bloomington. Fortunately there's not much population halfway between the two. Hopefully the area you mention is also sparse in population.William_Yeager said:How did WKMO land a construction permit to move to 107.3?

Can't say I fully understand what's going on with that, either. All I can understand is there is supposed to be a switch of frequencies and possibly the giving up of one, due to cluttering. I think FatPunk may have privy to the details...William_Yeager said:How did WKMO land a construction permit to move to 107.3?
isn't WUHU running 50kw on 107.1?
if a station runs more than 6kw on an class A frequency, is it still a class A?
they put a pretty good signal into parts of Nashville...

I'll say this...I know MOST of the details, its so complicatred I can't kep it str8 in my own head, and it'd prolly be better if I didn't go there.

That they do.
There's no such thing as a "Class A frequency" anymore. Docket 80-90 took care of that. You can have any class of station on any frequency. WUHU is indeed running 50kw, and they're a Class C2 station. The two "Fish" stations here in Nashville (93.7 and 94.1) are both Class A operations on what used to be Class C frequencies.
Minimum separation between a C2 and an adjacent-channel A is 55 miles if contour protection (directional antenna) is used. Without it, 65 miles is required. (and a place must exist at least 65 miles from the C2 station where the Class A operation would provide a city-grade to the city of license.

I didn't know that Salem's Fish stations in Nashville had 2 dial positions!?

Yep. Two separate stations - WFFH 93.7 Kingston Springs (west of town) and WFFI 94.1 Smyrna. (southeast of town) (I may have the call letters swapped) Between the two of them they do a pretty fair job of covering the market.

If you guys would do a little research, you'd know that the new frequency is directional. There is a null to the southwest that will protect WUHU.
And the FCC still assigns classes to FM (and AM) radio stations. FM classes are as follows:
C: 100 kW, 300 m to 600 m, HAMSL
C0: 100 kW, 300 m to 450 m, HAMSL
C1: up to 100 kW, under 300 m, HAMSL
C2: up to 50 kW, up to 150 m, HAMSL
C3: up to 25 kW, up to 100 m, HAMSL
B: up to 50 kW, up to 150 m, HAMSL
B1: up to 25 kW, up to 100 m, HAMSL
A: 100 W to 6 kW, up to 100 m, HAMSL
Some stations are above the maximum HAAT for a particular class, and correspondingly must downgrade their power. For example, WDJX in Louisville is a class B station. However, since they sit above the 150 meters AMSL, they radiate 24kW instead of the 50 kW allowed for that class.
For AM stations, classes are restricted to subsets of the available frequencies. For example, Class A stations can be found only on the frequencies of 540 kHz, 640 to 780 kHz, 800 to 900 kHz, 940 kHz, 1000 to 1140 kHz, 1160 to 1220 kHz, and 1500 to 1580 kHz. FM broadcasting isn't limited by subsets. If you can fit a class on an available FM frequency, you can put it there.
Sheese, in this age of the internet, any information you'd want to know on anything is available. I found this info on the FCC's webpage and Wikipedia and from just my own knowledge.

Oy, I'm not being mean. I'm just saying that instead of kvetching on a message board, look things up! It took me a grand total of 5 minutes to find out that WKMO is going to be directional on the new frequency.

Yeah...and we already have a 107.3 in the Etown area....KMO is moving to the freq THX started on.

Isn't it time for your MENSA meeting?
Are we keeping 'The Bear' or changing to something else? I asked Cat and he wasn't sure...of course, this was back in the fall when I was trying to get birthday greetings from past personalities. I believe I was told the Star was moving to a lower frequency. Is that right?FatPunk said:Yeah...and we already have a 107.3 in the Etown area....KMO is moving to the freq THX started on.

(mentioned, in that the necessary distance separation between WKMO and WUHU is reduced by 10 miles if a directional antenna is used)
And the FCC still assigns classes to FM (and AM) radio stations. FM classes are as follows:
Classes are still around but class discrimination among channels isn't.
Until Docket 80-90 came along, certain frequencies were reserved for Class A stations. (92.1/92.7/93.5/94.3/95.3/95.9/96.7/97.7/98.3/99.3/100.1/100.9/101.7/102.3/103.1/103.9/104.9/105.5/106.3/107.1)
You couldn't have a 50,000-watt station like WUHU on a Class A channel like 107.1.
Any station on a Class B/C channel was considered Class B/C and had to be separated from other stations on the same and nearby channels according to Class B/C distances. For WKMO to use 107.3 - a Class C channel - it would have had to be far enough from WUHU to not cause interference even if it was running 100,000 watts.
(the FCC did grandfather-in stations that were in excess of Class B and Class C limits, but for some reason nobody was grandfathered in on a Class A channel.)
(apparently the minimum power limits for Class B/C stations didn't yet exist; the 1966 FM Atlas shows a 2,300-watt/225' Class B station on 106.9 in Maryland and a 1,300-watt/200' Class C on 98.7 in Florida, among others.)

On the first question, I honestly have not heard of any flip. On the second, I think you are right.
