Is anyone besides me having problems getting the HD signal on KSL-AM to lock? For the past 2-3 days, the HD indicators on my Sangean HDR-14 and HDR-16 will flash when I tune to 1160, but I can't get the HD signal to lock no matter how I orient my radios. Also, I noticed that KUDD HD2 (KOOL 105.5) is MIA today. Anyone with an HD radio having similar experiences with these two frequencies?
EDIT: Just noticed that 100.7 Bob FM is also MIA on KUUU HD2, so something is definitely haywire with Broadway Media's HD2 channels.

FWIW, Broadway's HD2 channels are back on KUUU and KUDD today. I still can't get KSL-AM's HD signal locked in on my Sangean portables, but my Sony XDR-S3HD with an AM loop antenna will receive the HD signal. However, it sounds flat and sonically limited, much like a regular AM signal does. Tis a puzzlement!

I can’t get KSL-AM’s HD signal to lock in on my Sangean HDR-16 either.
I did notice that KUDD’s HD2 (KOOL-FM) was missing for a couple of days.
Also 106.7’s HD2 has been gone for a few days now.
Speaking of digital radio, KUER-HD3 (Classical KUER) is my new favorite station.

Speaking of digital radio, KUER-HD3 (Classical KUER) is my new favorite station. Do you live close to Salt Lake City, Terry? I had a couple of people in an AM radio group suggest that the problem has to do with my radios, and that AM HD requires a very low noise floor in order to get the HD signal to lock. I have my doubts as to whether that's true or not, because even once my Sony HD radio locked on KSL-AM's signal, it sounded flat and had a very limited dynamic range--not HD quality at all. I still think it's a problem with KSL's equipment and not my receivers. I've owned my Sangean HD radios for at least two years, and I've never had a problem getting either one to lock on KSL-AM's HD signal before. |

I’m in Murray. I’ve never had trouble getting KSL-HD before. KSL has a problem.

Hi Yul.  Multiple people with multiple radios and multiple problems. Hmm. My gut is saying that there was a transmitter software update and it isn't playing nice with your radios. I've got nothing to back that up but it makes sense. |

FWIW, I listened to Jeff Caplan's minute of news on AM 1160 HD2 in our car last night at 5:38 and it was in stereo. It didn't sound much different to me than it ever has. I don't think it's ever sounded as good as 102.7 HD1. It has this sort of warbly quality to it which I've also noticed on some of the channels on SiriusXM satellite radio. I think we were on about 7th South and Redwood Road. I normally listen to 102.7 HD1 but since this discussion was going on I specifically listened to it on 1160 so I could see if our car's HD receiver would pick it up. Does that qualify me for a renewal of my radio geek card? Have a great one everybody!

I tried my smaller Sangean, the HDR-14, and get the same result: KSL-AM flashes HD on the display but never locks on.
I then tried my old Sony tuner, the xdr-f1hd, and got KSL-AM in HD with its typical excellent quality, however, significantly, the HD signal was delayed by a few seconds. There has never been a delay before this.

Do AM stations that have broadcast an HD signal have that signal in stereo? My first car, that I bought around 1990, had a radio that tuned a couple of local stations in AM stereo. It never worked for KSL, but I assume that was because KSL broadcast a different flavor of AM Stereo than my car's radio was designed to receive. I recall that there were different competing technical standards and the FCC wanted to let market forces decide which standard prevailed. Which of course resulted in "none of the above". Which is why none of my subsequent cars had an AM stereo radio.

IIRC (and I may be wrong), KSL transmitted using the Kahn-Hazeltine system for AM Stereo and many car radios used the Motorola C-Quam method. |

When I could get the KSL-AM HD signal to lock on my Sangean HDR-14 and HDR-16, the displays showed that KSL-AM was broadcasting in stereo, and it certainly sounded like AM stereo to my 50 something ears. Several people in the AM radio group I belong to have said that HD radios have a decoder chip in them similar to the old AM stereo radios, but I haven't verified that statement myself. The fact that KSL's AM HD signal sounds so flat and lifeless on my Sony HD home receiver is what makes me think the AM HD equipment is failing. I can see the HD sidebands on the KSL signal on a Utah SDR, but I still can't get the HD signal to lock on my Sangeans. Never before in 2+ years of owning HD radios have I had that problem with a close range HD AM signal.
BTW, a special tip of my ball cap to CA for picking up on my Yul Brynner reference. 🙂

I've got an HDR 16 but it's in storage atm. I did check my little insignia ns-hd01 which only has fm and i'm guessing some sort of update happened / might have happened, and things will normalize soon enough.
Signals i can pick up:
KBYU HD1 and 2.
KUER HD1, 2, and 3.
KUUU HD1 and 2
KXRK hd 1 and 2
KZHT hd1.
KBEE HD1
KJMY HD1 and 2
KSFI HD1 and 2
KBER HD1
KSL HD1 and 2
KRSP HD1 and 2
I forgot to check KSOP and KNRS and my radio died.
KAAZ HD1
Signals I've normally heard as of late but am not currently, KRCL HD1 and 2
KAAZ HD2.

KUDD-105.1 is operating at lower-than-normal power, due to a transmitter problem.
As for KSL-AM, I'll have to set something up for monitoring. I wonder if they let the software license expire on the encoding.

i unintentionally left KUDD off this list. Both HD signals were loud and clear.

David, by "HD equipment" I assume you mean the transmitter that sends out the data over the air, right? If the HD transmitter was failing that wouldn't affect the quality of the sound. All the HD transmitter does is send ones and zeros. If there was a problem receiving the data it would be garbled nonsense not a lower quality audio.
Ken, your comment intrigues me. I knew there was a license fee but I never thought about how that would work before. I take it that it isn't a one time fee and instead Xperi uses a subscription model, yes? Without getting too far into it I'll just say that in my opinion ongoing charges for something that you ostensibly bought is a gyp and I won't do it. In any case, it makes complete sense that if the license has expired the station shouldn't suddenly go silent or there will be some irate customers out there. On the other hand, there has to be some incentive to re-up the license. Intentionally degrading the signal seems like a pretty good carrot-and-stick compromise, at least for a grace period. And we do know that even the biggest companies forget to renew expiring things sometimes. Microsoft's Exchange admin panel went down Sunday because they forgot to renew their TLS certificate.
