AM Frequency of the week: 740

From the far south KC metro:

Day: A very weak KRMG

Critical Hours: Marginally listenable KRMG and KTRH on rare occasion.

Night: Typically just fading. No signals identified to date. In a strong KRMG null...

Daytime: KMZN Oskaloosa, IA (formerly KBOE).

Nights usually CFZM Toronto. Often it is one of the strongest nighttime signals. Lately, not so much, and I've been able to catch KRMG a few times.
 
Daytime in NW San Antonio is KTRH with a medium-strong signal.

From sunset through sunrise, KTRH is stronger but subject to skywave cancellation. I get brief but rapid fades every couple of minutes or so.

Starting at sunset, XEQN in Torreón can be heard underneath or mixing in when I aim SE. At sunrise it sometimes takes over for a bit.

At night, aiming NW/SE I can hear a weak mix of stations underneath KTRH. XEKV in Villahermosa is heard the most often. Occasionally KVOR and KCBS will mix in briefly, but they're always very weak.
 
Here in Bremerton, WA, KCBS from San Francisco, CA is weak-to-medium depending on conditions.

Jim, I occasionally used to hear some garble, though extremely faint, under KTRH as close as Katy and once as close as the Galleria area (right around 59 and 610). I could never tell what it was as it was only audible (and one had to listen closely to hear it) during brief periods of silence in whatever was airing on KTRH. It was never strong enough to cause interference, per se, but it was there 10 years ago and likely still is. I am certain it was one or both of the Mexican stations you list here.
Always wondered how far west of Houston one had to be to start hearing cancellation on 740. Given that strong lobe, I figured it was somewhere in that stretch between Schulenberg and Luling.
 
blowtorch 50 Kw KCBS San Francisco "All News"...Where can't this station be heard, especially at night?

Look at the innermost contours for day and night at:

Remember, all the station cares about is the San Francisco Metro Survey Area. Period.

DX listening is different. I heard in many times in Quito, Ecuador. But that was occasional DX reception on a $500 receiver. Today, near Palm Springs, it is listenable almost every night; only when summer static is strong is it unlistenable.

From my travels.... I have no memory of hearing them at night east of Nevada. To the south they're solid in much of So-Cal, despite KBRT 740 moving inland from their former home on Catalina Island. KCBS is usually listenable at night in Hawaii, as well as in much of the Pacific Northwest.

740 originally was originally designated as a Canadian "clear channel". It has a 50,000-watt directional station in Edmonton, Alberta (CBX), and a 50,000 watt non-directional station in Toronto (CFZM). The latter has a robust nighttime signal in most of the Northeast and Midwestern U.S.
 
I picked up KCBS on 530 AM today. I have no idea what that means. I thought, maybe a translator, but you wouldn't need one for KCBS; not with its strength. Any thoughts?

Either an anomaly of some sort in your receiver or a harmonic from the KCBS transmitter, Just a couple of guesses.
 
Usually 740 is dominated nights by CFZM with a pinch of KRMG thrown in, but the last couple of nights, WVLN Olney IL is barging in. I'm guessing the 250 w Day pattern is still on rather than the 7 watt night pattern, either by accident or design. Full ID mentioning 107.1 FM at 4 a.m.
 
I guess I missed this thread when it was first posted.

So I can null KCIK from Kihei on Maui at night pretty much but I've never heard KCBS for some reason.

There is a station in the background that's gotten strong enough a couple of times to hear the words but I know it's not KCBS and I've never heard any ID.

And I have no idea what it could possibly be. It's a talk station.

When I was in Hawaii in 2010 I heard KCBS, but not very well.
 
From Mesa AZ:

Daytime: KIDR Phoenix. Nights: Mix of KIDR and KCBS.
 
Meriden, CT:

Daytime: WNYH, Huntington, NY, with Indian music and talk.
Nighttime: CFZM Toronto, with music spanning the '40s through the '80s.

I think CFZM has finally ditched 40s music. They used to have weekly mid-week with big band and 40s music program, that was dropped some time ago. OTOH, unless it was just an experiment, they now have a '90s at 9 hour weeknights at 9pm eastern. Right after 80s at 8 and 70s at 7,
