AM Frequency of the Week: 1170

Do you ever hear KGLC...KVIS on 910? Their Pattern is 1 kW DA-1, and is the equivalent of about 5 kW ENE and WSW.
KGLC "the Voice of the Cherokee nation in My-ah-muh Oklahoma" was a very frequent sunset visitor to my "shack" in Cleveland in the early 60's.
 
Ellensburg WA

Usually nothing in the days - very occasionally KPUG Bellingham WA (Sports) in winter.

Nights - KPUG, KLOK San Jose CA (South Indian music), and KFAQ Tulsa (News/Talk - now sports), now known as KTSB. But most of the time, an *insane* amount of IBOC hash from KSL destroys this channel.
Also, KYET Golden Valley AZ (Classic Country) was heard one time on day power, no, it wasn't on 1 watt.

It's Christmas time, and the North Pole would be nice to hear! KJNP, that is. No bueno so far.

This is an example of why Nighttime AM IBOC should still be prohibited: Although the programming on 1150 KEIB is only of interest to a small portion of the LA audience, for the over 1 million potential listeners in the San Fernando Valley, the nighttime IBOC interference from 1160 KSL is catastrophic, particularly in car radios. It is also problematic in SD County. Fortunately many stations have shut down their night time digital AM signals for this very reason. Years ago both KGO (810) and KABC (790) shut theirs down at about the same time because listeners of both stations complained of serious mutual interference.

It seems like a lot of them have quietly shut IBOC off recently. WJR 760 and WABC 770 were about the worst case scenario, and turned it off first. As I recall, they calculated that it raised their effective NIF contours to 14 mV/m. In Michigan, you could hear WABC IBOC interference to WJR in the Daytime, before Nighttime operation was even allowed, and it started during Critical Hours, and suddenly stopped at NYC Sunset. WABC's analog signal wasn't even that strong. When WSB shut theirs off, the mid 700s were an oasis of skywave signals. I'll have to check WBBM to see if they shut it down. The Detroit area stations besides WJR kept theirs until recently because they were the demonstrator test market for the car radio market. Some made no sense, 1 kW Class IVs/Cs and a 500 watt Day two site operation with 14 watts Night which didn't have it at the Night Site. I guess the chip shortage was the final straw. The Detroit Area IBOC stations interfered with the licensed Daytime service areas of stations 10 kHz and even 20 kHz adjacent. At least one station owner that was being interfered with even during CH skywave and with a very low power PSSA that was being interfered with by a 10 kHz adjacent, and they sold the station because of it.

Hey now, KYET broadcast in C-QUAM AM stereo. That AM stereo signal must get out far at night for 1 watt!
 
WBBM shut off IBOC just before the move to the WSCR tower. WSCR dropped it as well with the diplex arrangement after briefly trying to make it work. Reopened four frequencies for me!

I believe WFDF (910), WDFN (1130), and possibly WXYT (1270) are the only remaining stations in the Detroit market utilizing IBOC, at any time of the day. I'm only able to get a lock on these three. And I've never successfully decoded HD on any DX stations, despite having strong, interference-free signals at night. My Sony XDR-F1HD makes an attempt on WRVA, KDKA, and WGY but has never actually locked.

But, but... IBOC transmissions in the AM broadcast band are all in band, on channel, aren't they? :unsure:
 
DFW, Texas

Daytime: Spillover from local KBDT on 1160
Nighttime: KTSB (x-KFAQ) at nearly local strength, with XERT Ke Buena (Reynosa) under and sometimes overtaking, depending on conditions.
 
East Tennessee: Splatter from local WKCE, and a hint of WWVA around sunset (today in the 3pm hour). During one of this facility's off-air period I got KFAQ near sunset. A hint of WDEK.
Night: WWVA or not much of anything. In 2011, WWVA's towers were toppled during a "derecho" that passed through several states. WWVA's engineers rigged up a longwire to get back on the air and I could get that signal.
Retro/other: Not much of anything to report. Fun fact: Clear Channel was trying to find a way to move this signal into the Cleveland market at one tims.
The late U.S. Senator Robert C. Byrd had to intervene to prevent a move to Stow, Ohio, IIRC.

I think you're correct Greg. Byrd must have been one of many who intervened because the plan was abandoned. That was around 2004, I think.
I don't remember why such an idea even was conceived.

It would have ended up being some also-ran sports station in Cleveland more than likely
 
From NW San Antonio:

Day: Heavy splatter from local 1160 KRDY

Sunset: KTSB and XERT "Ke Buena" in Reynosa come up amidst the splatter.

Night: Splatter is reduced after KRDY goes to night power. KTSB is best heard aiming N-NE. It usually triggers flashing of the HD indicator on my Sangean HDR-16 but has rarely ever decoded fully into HD. XERT is best heard aiming SE, and KTSB can be nulled out fairly well in that direction.

Sunrise: Similar to sunset but with XERT a little stronger.

DX/Retro: I used to hear XECD in Puebla occasionally before it retired. A few times I've heard weak Spanish-language talk under XERT that I have not been able to identify yet.

Come to think of it, I do remember sports being mentioned with that format. Clear Channel must have wanted an all-sports competitor to WKNR, one that very well could have become the Browns' flagship or co-flagship.
It still would have been hampered in some of the market at night with the null toward Tulsa.
