Here's the central Kansas lowdown.
550 - KFRM, licensed to Salina but operated out of Clay Center, northeast of Salina (where the owners also have an FM based). 5KW day, 110 watts night, pattern goes south and west from 3 tower DA about 40 miles north of Salina. Farm station (think business news with an ag orientation), city grade goes south past Hutchinson and almost to Wichita.
900 - KSGL Wichita, 250w days/28w nights DA, mix of standards and religious programming. Directional is east-west on two towers in west Wichita.
910 - KINA Salina, 500w days/29w nights, DA. Fox oriented talk station, local in AM drive. DA beams northwest supposedly. Presently on an STA with 125w days due to problems with the antenna that reportedly day from the day after it was built.
950 - KJRG Newton, the heritage religious station in the area, now owned by Bott. 500w day/147w night non-directional on a 440' tower. Signal gets out about 70 miles during the day, and puts a good signal about 20-30 miles at night depending on direction from Newton.
1070 - KLIO Wichita, 10kw days/1kw nights, DA-N. This for years was legendary country KFDI, today running True Oldies format. Has best day signal in Wichita, night DA is a very tight figure 8 that is roughly N-S in orientation. Covers core of the city well but has a lot of problems in the east and west suburbs where Wichita's growth is.
1150 - KSAL Salina, 5KW, DA-N. One of just just 3 stations in Kansas west of Topeka that has 5KW nights. Night DA is mainly west with side lobes going NNE and S. Station can be picked up most days in parts of Wichita with a daytime coverage that rivals some 50KW clears. (NIF is an area best just over 3 mv/m) News/Talk station with the big national hosts (Rush etc.) plus local AM and PM drive, local sports, and Kansas State.
1240 - KFH Wichita (also see 1330 below). Wichita's graveyard station, 630w ND. Tower located near 21st and I-135, very close to the center of the urbanized area. Station started out as KANS in 1936, then became KAKE when KANS moved to 1480. It later was known under two other call letters before becoming the original home of News/Talk KNSS, now at 1330. Runs ESPN sports and other talk, simulcast on 98.7 FM (C2 licensed to Clearwater, south of Wichita) for the only full simulcast in the region.
1330 - KNSS Wichita. 5 kw DA-N. Long time home of KFH before Entercom made a frequency swith to put the news-talk on the best night signal/number 2 day signal in the market. Tower is located in east Wichita right along Wichita's long time "Yuppy Way" (Rock Road). Nulls on night pattern equate to a 1kw signal, more than adequate to cover core metro. DA pattern at night is oriented NNW-SSE (roughly towards McPherson and Arkansas City respectively). Has Rush and all the other big talk shows.
1360 - KAHS El Dorado. 1kw day/240w night, DA-2. Catholic satellite programming. At one time was a 500w daytimer targeting home Butler County. Past owners then tried to target Wichita, despite a huge signal problem in parts of town (especially in the area of the 1330 tower). Day DA is southwest, night beams straight west from just east of El Dorado.
1410 - KGSO Wichita. 5kw day/1kw night, DA-2. Sports talk. DA from north wichita goes southwest days, mostly south with side lobes E-W nights, the most complicated night pattern in town. Has operated under multiple call letters-formats over the years.
1450 - KWBW Hutchinson. 1kw graveyard station. Arguably has the worst nighttime signal of any station in the area excepting the flea power operations (and one of them actually has a better night signal), getting out 10 miles at night can be a challenge. News/talk with Rush etc plus a lot of local talk and sports. It's long had signal issues, but does well in the city of Hutchinson which is all they really target.
1480 - KQAM Wichita. 5kw day/1kw night, DA-2. East-west pattern day and night, with a deep null north at night from tower in NE Wichita. Has probably the 2nd best night signal in the market, especially on the east side where a lot of money is. Station runs mostly 2nd tier talk programming plus does local sports (sister station to 1410).
1540 - KNGL McPherson. 250w day/2w night (does not use night power), ND. One of just two AM's in Kansas that still runs on a dawn-dusk schedule. Airs 2nd tier talk programming, plus does some similcasting of sister class A FM KBBE 96.7. For the power it has, it has an incredible coverage thanks to a tall (277') tower. The oil refinery next door NW does create a directional effect on the signal, nulling it in that direction - but you can still get a decent signal 20-25 miles in that direction.
