KJMM Question

What is the actual power for KJMM on 105.3? I know it's listed as 10kw but I've heard from a few sources it's 50kw. So what is the actual power for the station?
 
KJMM is a c2 FM the station would normally run 50kw, however the tower height is over 500ft and the station operates at 10kw which equals 50kw.
KJMM is operating at the max power permitted
 
It's a little confusing somewhat, but I think get it. It sad that a station such KJMM has a 10/50kw signal that covers Tulsa well but can't crack past a 2-3 share in the ratings. The last book they had it was at a 1 share. That is sad, and I listen to the drops on the station how they're all that, but can't get any ratings. Until the station gets some numbers up to where KTBT and KHTT are then you can talk all the noise you want, but right now they're talking loud, ain't saying nothing.
 
They have shown up nicely in some of the younger demos like 18-34 recently. I think they do an admirable job with the resources they have. It works for advertisers, I have tried to sell against them on occassion. Martha, their GM, is a great lady and the only female GM in Tulsa. Signal stinks though.
 
Glad to see they're doing well as far as advertising, what part of town are you in where you can't pick up the station that well?
 
I'm in Owasso. Have no clue where their tower resides. I know they broadcast from 71st and Yale.

They're licensed to Bixby, and their tower is located closer to Haskell:

They cover Okmulgee & Muskogee better than they do Owasso:

Wonder what adjacents prevented them from moving further north....
There's an 11,200 watt cochannel licensed to Columbus, Kansas, and a 100,000 watt cochannel licensed to Haysville, Kansas, as well as KINB in Kingfisher.

I was looking at the FCC link for KJMM's coverage map, and inside that circle it looks like it covers Owasso well. I would assume anything inside the circle you would get great coverage.
 
#1 - Don't bet on great coverage in that circle. The FCC loves to over-estimate coverage. Look at some of the AM coverage patterns & you'll laugh yourself silly.

#2 - KJMM's processing has always sounded weak at best. With a low volume, noise & interference is more obvious, thus giving them a "worse" signal than comparative stations. I'm no fan of crushing audio, but check out 101.5... it's only 6 KW, but it's a blowtorch because they've got the processing set so hot. They are "there" right to the edge of their signal while 105.3 can start sounding static-y in parts of south Tulsa.

That explains it! :)

I agree about the processing on KJMM, and their sister station KVSP Power 103.5 in OKC is no better, their processing is weak as well and you hear a lot of popping when the jocks talk. The station's processing sounded better on AM 1140 than it does on FM.
 
A different engineer set up the am than the fm. The studio equipment selection was different for the fm studio than the rest of the complex. My guess on the popping of the mics is the style of the mics the fm studio has. They are powered mics opposed to the normal dynamic mics used elsewhere. I personally am not a fan of powered mics for radio station on-air rooms.
 
Back when KVSP 1140 used to simulcast on 1340 during the evenings and weekends, their sound (in my opinion) was even better on 1340 than on 1140. I could flip between 1140 and 1340 in the summertime before 1140 would sign off, and the difference was noticeable. They sounded really good on 1340. My work truck at the time had an AM stereo capable radio, and it would indicate that 1340 was in stereo (1140 wasn't indicated as stereo). The actual audio was playing in mono, but that may be why it sounded so good. I venture to guess that 1340 is no longer broadcasting in stereo, and I don't have an AM stereo radio anymore to try it out.

I didn't know AM 1340 was broadcasting in stereo. Before Perry Broadcasting owned AM 1140 when it was KPRW, 1140 use to broadcast in stereo back in the mid-late 80's, some of the jocks with make mention of it in a break. I even heard one jock on the air in a break call it Stereo 1140. My aunt use to have a Chrysler car (don't remember which one it was) but the Chrysler cars would indicate AM stereo if you listened to a station AM and sure enough KPRW did broadcast in stereo at the time.
 
I think the AM stereo on 1340 dated back to when they were simulcasting 96.1 KXXY. I do remember KPRW's AM stereo days, though I was just a teenager back then with no access to an AM stereo receiver. Back then, you could buy an AM stereo tuner at Radio Shack to add to your component system. I lived in Moore back then, which is close to 1140's tower, so I bet AM stereo would've sounded good for me back then.

I wonder if any Tulsa or OKC stations are still broadcasting in AM stereo? It's a shame they didn't chose a single AM stereo standard from the beginning. That could've possibly made AM stereo catch on, though I doubt it. If AM stereo would've come into play in the 1970s, it might have been more successful.

A bit OT now, but I wish 1340 would go back to simulcasting KTOK in the evenings. My house is in the Windsor Hills area, and in a null of KTOK's evening signal. 1340, however, comes in quite clear here day and night, as I'm only a few miles away from 1340's tower by the capital.
