ABC DRM Test.
There is DRM on 747 now. I’m getting decoding on both Melbourne & Adelaide Kiwi’s. Nothing this side of the Tasman though.
As I read the licence this is a DRM/AM simulcast test using the 3RN licence. The “thou shalt not interfer” will be to make sure local listeners on 756 don’t get too much hiss from the DRM signal. This was a bit of an issue when there were simulcast tests on 657 kHz in Wellington years ago.

Canada

Canada finally has an AM station testing digital HD on AM, rather than the usual practice of placing AM stations on a co-owned FM’s HD channel. As well as
being “first on the dial” at 530, CHLO was also the first station acquired by current owner Evanov.
530 ON Brampton CHLO June 8th marked the beginning of digital HD testing in Hybrid IBOC, making CHLO the first station in Canada to use HD on AM. There is already a report of interference on the international maritime Navtex frequency of 518.

For the first time since it began broadcasting on Aug. 11, 1932, White Plains radio station WFAS can no longer be heard on standard AM radios.

Cumulus Media, which owns 415 radio stations in 86 U.S. markets, has shut down the station’s analog AM transmitter, leaving only electronic noise to be heard on standard AM radios tuned to the WFAS frequency of 1230 on the AM dial.

Cumulus has converted WFAS-AM into AM1230Digital and is transmitting a digital signal that can only be heard on digital AM receivers. Cumulus says that the digital signal will offer listeners equipped with digital radios better sound quality while covering an expanded area beyond Westchester County. I

The station’s new coverage area includes large portions of New York City, the North Shore of Long Island, northern New Jersey and Fairfield County.

According to the National Association of Broadcasters, approximately 25% of the vehicles on the road in the U.S. have radios that are capable of receiving digital AM signals. The Federal Communications Commission has approved use by U.S. broadcasters of the digital radio technology known as HD Radio MA3 and foresees a gradual voluntary transition to digital broadcasting on the AM radio band.

Cumulus says that the new AM1230Digital is the first digital AM radio station broadcasting in the New York metropolitan area.

Cumulus several years ago ended WFAS-AM’s programming as a full-service community-oriented station and now offers a news-talk format on weekdays and CBS Sports Radio on weekends. The former “WFAS” referred to Frank A. Seitz, father of station founder Frank A. Seitz Jr.

In 1947, WFAS added an FM station to its existing station on the AM band. Beginning in the 1950s, both the AM and FM stations operated from studios on Secor Road in Hartsdale. AM1230Digital now gives a contact address in New York City.

In 2014, Cumulus changed the call letters of WFAS-FM to WNBM and moved the transmitter site to the Bronx and began programming the station from existing Cumulus studios in Manhattan.

When Cumulus Media’s 1230 WFAS White Plains NY turns on its new all-digital signal on Monday, May 24, it will do so with an all new Talk lineup.
Positioning as “New Talk For New York”, WFAS will clear many syndicated talkers currently lacking clearances in the market. The station will carry “America In The Morning” hosted by John Trout from 6-7am and again from 8-9am. In between will be Michael Toscano’s “First Light” from 7-8am.

Digital Radio Mondiale in Focus in India.
Right from the beginning of 2021, Prasar Bharati, the public radio and TV broadcaster of India, has put its cards on the table. First it clarified that no AIR station was being closed anywhere in any state, a rumor that had made the media rounds in India.
[….]
The AIR Network already comprises a few hundred stations and several hundred radio transmitters in one of the world’s largest public service broadcasting networks that operates on multiple terrestrial, satellite and internet platforms.
[….]
Already in 2020 AIR had introduced nonstop pure DRM transmissions with three services or programs on one frequency in four key metros: Mumbai 100 kW (1044 kHz), Kolkata 100 kW (1008 kHz), Chennai 20 kW (783 kHz) and New Delhi 20 kW (1368 kHz).

WMGG Has Turned on All-Digital AM.
Tampa-area station is the first since the FCC changed its rules.
A Florida AM radio station is now on the air full-time with all-digital transmission, committing its 1470 signal strictly to listeners who have digital receivers.
Neal Ardman told Radio World that WMGG switched on its new Nautel transmitter, purchased for this purpose, on Tuesday morning. The station has an FM translator that continues to serve analog listeners at 96.1. The station airs Spanish-language programming.
If all-digital HD Radio technology for AM takes off in the United States, WMGG’s move would be seen as an important milestone.
