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.

The highpower transmitter of Roumoules used until a few months ago by Radio Monte-Carlo on 216 KHz could have a future with the DRM transmission system. This, briefly, is what emerged after an exchange of emails between the French DXer Christian Ghibaudo and Mr. Pennella, one of the technical managers of the Monegasque broadcaster’s website.
Original text from Radioascolto:
“Il trasmettitore superpower di Roumoules utilizzato fino ad alcuni mesi fa da Radio Monte Carlo sull’onda lunga dei 216 KHz potrebbe avere un futuro con il sistema di trasmissione DRM. Questo, sinteticamente, è ciò che è emerso dopo un scambio di emails tra il dx francese Christian Ghibaudo e il signor Pennella, uno dei responsabili tecnici del sito dell’emittente monegasca. Come i nostri lettori ricorderanno, un paio di giorni fa abbiamo parlato della strana ricomparsa delle trasmissioni di RMC-Info Talk sport sulle onde lunghe rilevate dal milanese Giroletti e dal sottoscritto lo scorso 24 novembre. L’amico Christian, profondo conoscitore della realtà monegasca si è immediatamente attivato presso i responsabili dell’emittente per scoprire l’origine di queste trasmissioni. Dal signor Pennella ha appreso che si trattava di test di trasmissione in simulcast della durata di 10 minuti con una potenza di “soli” 400 KW in vista di un utilizzo del sito col sistema DRM. Per questo motivo i responsabili tecnici dell’emittente sembrano intenzonati a coinvolgere gli appassionati di radioascolto in grado di ascoltare la radio con questo sistema.

Pakistan Broadcasting Corporation (PBC) has requested that the Government includes the Policy for equipping all cars in Pakistan with DRM receivers in its automotive policy.
This will be discussed for inclusion in the Automotive Industry Development and Export Plan for 2021-2026 of the Ministry of Industries and Production. PBC representatives will be part of the consultative body that will issue the new automotive policy.
This represents yet another major step in the already significant progress made by PBC towards the roll-out of the DRM digital radio standard in both the AM as well as VHF bands in their country.
This policy will be a key driver for all major automobile brands and OEMs to prepare and produce line-fit DRM radios in their new cars and also to provide solutions for the after-market vehicles in Pakistan.

These channels along with AIR Chennai 783 kHz (20kW) & AIR New Delhi 1368 kHz (20 kW) both of which that had already changed over from AM to Pure DRM mode some time back will operate continuously for 22 hrs. per day in Pure DRM at 5.00 pm to 3.00 pm IST (ie 1130 to 0930 UTC) with 3 program channels from tomorrow.
Note: The following channels of AIR from these cities will however still be available, on AM Mode on MW:
Kolkata: 657 & 1323

A Florida AM radio station plans to go all-digital soon, now that the Federal Communications Commission has allowed such transitions.
WMGG is owned by NIA Broadcasting; it’s a Class B station in Egypt Lake, Fla., near Tampa, airing a directional signal via a diplexed array. It has 2.8 kW power by day and 800 watts at night, and airs on 1470 kHz.
The company also owns several other AM, FM and TV properties.
President Neal Ardman told Radio World he is in the process of ordering a Nautel HD Radio transmitter to make the change.
“It is time,” he wrote in an email, adding that he is “not worried” about losing analog listening.
WMGG has an FM translator on 101.9 MHz. Both signals are part of “96.1 FM Caliente,” the radio home of the Tampa Bay Buccaneers’ Spanish-language network.

After the disruption caused by the pandemic, All India Radio (AIR) decided not only to restart transmissions in pure digital mode but also to expand DRM MW digital Radio services.
According to a recent decision of AIR, the stations with single DRM MW transmitters are to carry two digital audio channels in simulcast mode and three audio channels in pure digital mode with Journaline.
Timings of the pure digital mode are likely to be announced shortly. In the meantime all the DRM MW stations have been asked to carry out test transmission immediately, to ensure readiness and sustainability of the transmitters for regular transmission of DRM in pure and simulcast modes.
This will be an opportunity to carry out field survey . In simulcast mode two digital audio channels and one Journaline (if feasible) is to be tested. In pure digital mode, three audio channels will be available with one Journaline (if feasible).
Whether in simulcast or pure DRM the first channel will be News 24×7. In pure DRM the third channel will be the popular Vividh Bharati music programme.
It has further been decided that five major stations (Delhi, Mumbai, Chennai, Kolkata and Rajkot), which have 2 MW DRM transmitters each, will operate one of these transmitters in pure Digital mode throughout the day.
Six more stations (Hyderabad, Vishakhapatnam, Jagdalpur, Bhawanipatna, Sambalpur and Jeypore), which have digital ready MW transmitters, have also been asked to test these transmitters for DRM digital transmissions. Infact test transmission in DRM has already started from Hyderabad and Vishakhapatnam is almost ready.
