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.

Ft. Wayne owner pulls plug on Digital-Only AM test after listeners complain.
As the Federal Communications Commission weighs whether to allow AM stations to voluntarily switch to all-digital broadcasting, a test run in Fort Wayne, IN offers a cautionary tale that the move from analog isn’t right for all operators. Owner Brian Walsh switched oldies WIOE (1450) to a digital-only signal in late May but he quickly moved back to an analog broadcast. Walsh reinstated the analog AM stereo broadcast in early-June from 6am to 6pm after he heard complaints from listeners who were no longer able to receive the station and believed WIOE was experiencing technical problems rather than taking a step into a digital future. That is despite the fact that WIOE has an FM sister – WIOE-FM (101.1). While AM digital remained in overnights, Walsh threw in the towel last month when he returned to analog 24-hours a day.
“I underestimated how many listeners were on that AM radio station,” said Walsh. “We couldn’t quite make that bridge with all the emails and phone calls that were received from listeners and I felt it was hurting the overall product of the station.” He told the Radio Show on Tuesday that WIOE’s format has been on the air for 18 years and its ratings have been solid, two factors that seemed to have worked against the move.
Despite his experience, Walsh said the digital AM signal worked as advertised with improved coverage and building penetration and less interference. “It just works perfectly all the way around,” he said. Listeners simply didn’t have the digital receivers to hear it today. Walsh hopes to one day resume WIOE’s digital broadcasts, and in the meantime it continues broadcasting in analog AM stereo.

Indiana AM Station Suspends All-Digital Transmission.
After about four months in all-digital mode, an AM radio station in northeast Indiana has turned off MA3 digital operations for now and returned to analog transmission.
WIOE(AM) in Warsaw, Ind., was the second station in the United States to conduct such an experiment on the AM band. The station serves the Fort Wayne market.
Owner Brian Walsh was enthused about the quality and coverage of the signal. But he told Radio World he ended the experiment on Sept. 11 because of a lack of interest from listeners.
