AM Frequency of the Week: 770

This week, how about double 7s. Wirh a zero following. What are you hearing on 770?

Here in the far northwest suburbs of Chi-town, daytime it's splatter from blowtorch WBBM. 20 or so miles away from me.

Nights, I can null WBBM and it's IBOC and WABC is usually strong enough to break through. Before WBBM turned on its IBOC noisemaker, I could also sometimes snag WVNN from the Huntsville, Alabama area.
 
In the near north Chicago suburbs it's all WBBM noise for me 24 hours no matter if I attempt to null it. Before IBOC, WABC was a regular and often very good night signal here.
During their Musicradio days WABC was a nightly listen for me.
 
Daytime - A barely audible WJBX Ft. Myers.

Nighttime - Most of the time, it's Cuba with WABC in the background but sometimes WABC dominates.

But at night, WABC is not nearly as strong here as it is on the east coast of Florida where it often booms in very loud.

Here it is from Daytona Beach.

Here just east of Columbus, Ohio, it's a moderately weak WAIS out of Buchtel, Ohio (50 or so miles SE) daytime and all WABC at night.
For all intents and purposes, WAIS is in Nelsonville. Transmitter and studio are just outside town off U.S. 33.
 
Eastern Iowa: nothing during the day. Maybe some WBBM residue. Nights: usually WABC. This is one of those signals that I swear is stronger than it was back-in-the-day (discussed in another thread). Which is a shame, because look what WABC has turned into... how far down have they slid in the NYC ratings?
 
May 10th 1982 was a dark day in radio.

That last day WABC played music was the official end of the AM top 40 era. (At least to me)

Sure, some of the other big AM stations continued to play top 40 for a few years after that but having grown up with WABC, that day in May of '82 was the transformation point of AM radio being accepted as a talk venue.
 
From Houston, daytime, a very weak KAAM. Night - KAAM is stronger with stuff underneath. WABC used to be a nighttime presence in Houston if you could null KOB - but neither WABC nor (now) KKOB seem to be present. But there is Spanish language under KAAM.

Yeah it was a big day. Really the beginning of the end of big 50KW AMs playing music. You had WLW, WGN, WBZ and others playing music into the 90s, with WHAS being pretty much the last holdout (they dropped Joe Donovan in August '97), but the top 40 era basically ended then.

Here on 770 we get a very weak WLWL Rockingham, NC with oldies music. A 5kw daytimer. WABC comes in during critical hours, and of course at night. That WAIS has a pretty good signal. One of the strongest AM signals in southeastern Ohio.
 
Down S.A. way, 770 has nothing but IBOC hash from local 760 KTKR "The Ticket" during the day. When KTKR goes to night power, the hash goes away. At night, aiming northeast, KAAM and XEACH "Radio Fórmula" in Monterrey take turns swapping out for periods of time (KAAM hanging in there longer), each with fairly strong signals when prominent. Aiming west, KKOB comes in and out. Back in January I once logged XEIH in Fresnillo.

This morning before sunrise, I logged a new one, XEREV "Los 40 Principales" running 0.1kW from Los Mochis. At precisely 6:28 a.m., KTKR went to day power and the IBOC hash killed everything.

I'll have to see if I can get 760 in HD. I wondered why a 50 kW station would be so weak compared to 550, 630, 680, 720, and 1200 - all of which sound semi-local. I get jumped on for saying that HD saps AM power and range, but here is another excellent example. I bet they would really get out better if they dumped HD. What the heck advantage does HD even bring to a sports format? Cheering crowds out to 15 kHz in stereo? No thanks!

The reasons have nothing to do with HD. The reasons are site location, directionality, tower height and ground conductivity.
