99.5 KIIM Tucson... 90 kw/2037 feet above average terrain
vs.
97.1 KNST-FM Green Valley... 1750 watts/614 feet above average terrain
Now really, where in America does a Class A station successfully compete with a Class C station in the same format, a format they've been doing for decades?
Meanwhile KNST-AM has 5000 watts by day. But at night it drops to 500 watts. I see in the latest ratings KNST, both AM and FM combined, is #6, about half the ratings of KIIM, which is always #1, sometimes with double digits. Does Clear Channel believe its AM station, which drops to 500 watts at night, won't be hurt by being on AM only?
All across the country, AM stations are trying to find low-powered FM translators, so they can tell their audience and advertisers their station can be heard on FM as well as AM. 97.1 might be more powerful than a translator, but not much more. Does Clear Channel really trust 500 watts to keep people listening at night who don't live in downtown Tuscon?
If you were an advertiser with KNST, wouldn't you ask for a big refund if your spots only are being heard on an AM station that drops to 500 watts at night?
By the way, for a top 100 market, it seems Tuscon has almost NO AM stations with decent power at night. In fact, 1330 KWFM is the most powerful nighttime station in Tuscon, with 5000 watts. Nearly everyone else is 1000 watts after sunset: KFLT, KTKT, KVOI, KEVT, KCUB, KTUC, KTZR, KFFN and KXEW. KNST joins several other Tuscon AMs with less than 1000 watts: KSAZ, KCEE, KGMS. And KGVY and KUAZ sign off at night.
How did Arizona get so shortchanged when they were handing out the big-powered AM stations? Waterloo Iowa, Roswell NM, Cheyanne WY, Boise ID, Rochester NY and Eugene OR all have AM stations that run 50,000 watts around the clock. In all of Arizona, only Disney's KMIK Tempe runs 50,000 watts at night, and that only happened in the 90s. Back when they were KNIX-AM, owned by Buck Owens, they had to sign off at night.
