You're right, there is no AM here. If I want to listen to KFAY, I just say "Alexa, play news talk 1030". The radio will not pick it up reliably. This is purely a skywave town for AM. The ground conductivity must be horrendous. Losing 790 KURM meant no more listenable signals at all here in Northern Benton County.
So, you're the person who still listens to KFAY 1030! 😉 Even 30 years ago, it wasn't much of anyone's first choice for news. KURM always did a much better job of covering local and national news, and Cumulus gutted KFAY almost entirely during the Great Recession. KFAY hasn't had much to offer for a long time.
AM has always been a wasteland there. At the time KHOG proposed moving to 1030 and operating 24 hours, the area only had one AM operating after sunset, and it was on 1340 and maxed out at 250 watts at nighttime. Seems like KURM, which was late to the game and started out a daytimer, used a similar argument to go 24 hours, and I believe it was running 24/7 before KHOG. FM wasn't much better. KEZA 107.9 signed on in the early to mid 80's, and it was the first Class C FM licensed to Fayetteville. The only other Class C FM in the area at the time was KMCK, which has been a Class C the longest. The others were either Class A's that upgraded in the early 90's or sign-ons in the early 90's. I think KKIX and KUAF were the first to upgrade.
Ground conductivity is pretty bad there, but KFAY has had other challenges, too. When that three tower array went up in the early to mid 80's, it was an isolated area. The car dealership and the Sam's Club weren't there. That dealership has expanded in phases, and each one has encroached further toward the tower site. The Fulbright interchange has also been redesigned multiple times. (I'm told Calipari's house is just to the northwest of that interchange, BTW.) I can't remember if the bypass had been built when the towers went up, but, when 1030 was proposed at that site, it wasn't there yet. I-49 was US 71, and what's now the Fulbright was the original US 71. US 71 dropped you onto College where the Fulbright ends today, and that section of College and north became US 71 while the part south that took you into Fayetteville was US 71-B. If you were going to Springdale, you had to drive up College and Thompson starting at roughly the Northwest Arkansas Mall. You could stay on it and go to Rogers, Bentonville, and Bella Vista. It was stop and go driving all the way up to Missouri. What's now I-49 was built in phases with construction on the part from the Fulbright to Sunset Ave beginning in the early to mid 80's. Most of the rest of it continued going up throughout the decade and into the 90's, though the Bella Vista bypass just went up within the last 10 years. The southern leg toward Ft. Smith went up during the 1990's.
What's happened to KFAY has been a problem for a lot of other AM's, too. Unlike FM's, AM tower sites require a lot of land. Even if it just has one tower, it has to have an extensive grounding system. When those stations were built, they were built where the land was cheap. Today, much of that land is no longer cheap. As that land has become more desirable, businesses and builders have been acquiring that land and putting in businesses or homes. Each new parcel of land that encroaches on it is a potential problem for the station. Those rare situations where the land is still cheap have also had to deal with encroachment. That encroachment has typically been residential, and it's usually housing for lower income people. I've heard horror stories about engineers having to drive out to tower sites in dangerous neighborhoods. Plus, all AM stations have to worry about copper thieves trying to deal the grounding system. A station where I interned saw some copper thieves fry themselves in an effort to steal its grounding system.
But, I live in two metros, splitting my time about half and half. In San Antonio the situation is the opposite - maybe 30 AMs, all with something interesting going on. Even iHeart flagship WOAI has no need for a translator or presence on FM HD. There is almost no power line noise in the city.
Ground conductivity is good in San Antonio. Signals, in general, seem to travel really well around there. Having said that, most of the AM's there were still designed for an area that was much smaller and less populated than it is today. Most of the AM's either cut their power too low or beam their signals straight into the Gulf of Mexico after dark. KKYX is west of the city and can still hit the bulk of the population, but, while you can hear it all the way down I-37 to Corpus Christi at night, you can't hear it much past Kerrville after dark on the I-10 run. KTSA is much the same after dark. It's a great signal to the southeast but doesn't go too far northwest. With much of the area's growth being in Comal and Kendall Counties, AM misses out on more and more of the population every day.
