HD Radio

None of the AM stations in Milwaukee run HD. I recall WTMJ dumping it years ago because the delay messed with sports broadcasts. That, and they're on 94.5 HD2 and the 103.3 translator, making it even more irrelevant. WISN doesn't run HD either, but is on an HD subchannel on FM.

Audacy dumped HD on WSCR and WBBM as well.

The REC listings are pretty incorrect on the HD notations in general. For example, in Milwaukee, they show 98.3 and 106.9 in HD, but neither uses it.
 
Very few AM stations are still transmitting in HD nowadays. Most of them are are on HD subchannels of sister FM stations.
 
WPR turned off the HD signal on 970 AM (WHA) back in May 2024 -- happened around the same time they realigned their two statewide networks into WPR Music and WPR News.

The REC listings for HD reflect which stations have given the FCC notification that they were using HD. Since there's no process for notifying the FCC that a station has stopped using HD, they're not going to reflect the reality that very few AM stations that once used HD are still using it now.

Actually, there is a process - file another Digital Notification and select the type of notification as Reversion from Hybrid to Analog. That's what Wisconsin Public Radio did last year. It's not common for stations to do this though - Digital Notifications are more commonly filed for stations that have begun broadcasting in HD, or are about to begin.

One possibly nice side effect of the turning off of HD on AM signals is that it might assist those DX-ing on frequencies adjacent to the frequencies that had the HD signal.
 
There is no AM station in Chicago/Milwaukee/Madison region currently running HD. WHA was the last holdout; as noted above, they shut it down in Spring 2024.
 
Strange that there is no information showing La Movida (WLMV AM 1480) my HD Radio locks into La Movida as an HD AM signal - but I seriously question that - it actually sounds like AM Stereo because I have an old AM Stereo transistor radio and it also shows a Stereo Light on AM 1480
 
Absolutely no idea if they're still using the equipment, but 1480 in the mid-80s when it was still WISM was "Solid Gold Stereo".
Another station that is also in AM Stereo is WHIT (AM 1550) and another one that I've seen WNCW (AM 1190) - I have noticed WNCW only carries AM Stereo randomly, not 24/7. I have witnessed both WLMV and WHIT packing AM stereo without fail and it appears to be 24/7. There appears to be a noise that sounds like farting or slow motion burping on AM 1550 - my guess is that's AM Stereo not locking in but WLMV does not have this bizarre farting or slow motion burping sound.
 
Is (was) AM HD part of the deal when manufacturers paid for HD "licenses" for their FM receivers too? Or was (is) it extra?
Good Question I wondered that too - I wish I had the answer on that particular licensing question.

I actually have a DAB radio that I got on accident on Amazon, this was before I knew HD Radio was NOT the same as DAB.

Shockingly - there is a DAB station in Madison near UW Madison - it's on 95.1 FM I believe it comes from Tripp Residence Hall.

Based on records It's a pirate radio station.

Licensing information:

I do know that DAB doesn't have licensing where HD Radio has "licenses" to be paid to even carry HD Radio, and each HD radio station is a separate license.

If you are a radio station licensee - HD Radio can get expensive very quickly - and not every radio supports HD Radio.

I would say it's quite a niche market - similar to AM Stereo - often times it's not feasible to deploy HD Radio or AM Stereo for smaller market stations the majority of audience doesn't have such radios available.

The ROI is highly questionable so most stations would ask themselves is it really worth it - between the licensing fees for HD Radio or AM Stereo given the scarcity of HD Radios or AM Stereo being made or being available.

For example:

WSJY - 107.3 HD1 - WSJY - Your Variety Station - That's The 1st License
WSJY - 107.3 HD2 - WFAW Simulcast - Additional License - 2nd HD License Paid for
WSJY - 107.3 HD3 - WKCH Simulcast - Additional License - 3rd HD License Paid For
WSJY - 107.3 HD4 - WBKY Simulcast - Additional License - 4th HD License Paid For

DXing is of less than zero interest by stations. The largest AM DX club in America has less than 1000 members.

Back when HD was introduced, in a presentation to HBC, Bob Strubel of iBiquty said that licensing was a single price and single chip for radio manufacturers.

The station license charge was significantly reduced in the early years of HD and is not a significant cost. It's based in part on the station facility and its market size as well.

At no point was it "very expensive".

Yeah it was very cheap when it first came out - things have changed since 2008. It's not too expensive but Very few brand new stations launch as HD Radio stations. The last NCE window in 2023 shows no signs of new stations launching with HD Radio

Most folks don't have HD radio so most HD stations that I have personally seen have a translator from what I have personally seen - that's when it becomes super expensive. If you just leave the HD Radio without the translator yes it's cheaper than a translator
