1. The Dharma Radio Station Group, Block 9A in the Bangkok and surrounding areas. Stations participating include Dharma for the People Station and Santi Radio Station;

2. The Khon Kaen Station Group: block 6C in the areas of Khon Kaen and Maha Sarakham, with stations such as Khon Kaen Mahanakhon Radio Station, Sai Fah Radio Station, Thai Local Radio Station, etc.

In October/November 2024, the NBTC published three key digital radio broadcasting technology announcements:

The radio frequency plan "covers the assignment of frequencies, technical specifications and conditions of use of frequencies for digital broadcasting in the 174 - 230 MHz radio frequency band. It defines the radio frequency blocks that can be permitted for use in each area and specifies the use of the Digital Audio Broadcasting (DAB) system with MPEG-4 High Efficiency Advanced Audio Coding version 2 (MPEG-4 HE AAC v2) audio codec, or DAB+ Audio."

In June 2024, the Royal Thai Army Radio and Television Station presented a summary of the results of its DAB+ experiment. It has tested both outdoor and indoor listening, as well as testing sending short messages and Emergency Warnings or breaking news. The test results were satisfactory, broadcasting quality is good in every sector, except in Chonburi, where parameters need to be adjusted in some areas. “The results of this experiment allow the NBTC office to receive useful information that can be further developed. The next step is to present it to the NBTC for approval in the criteria and methods for granting permission to create a network operator that can provide services to radio station operators in community, public and business categories,” said Air Chief Marshal Dr. Thanaphan.

From 2018, the National Broadcasting and Telecommunications Commission of Thailand (NBTC) in conjunction with the Royal Thai Army Radio and Television ran a high power DAB+ trial in the Thai capital of Bangkok. This was completed in July 2023.

There are DAB+ broadcasts in four major regional areas, Chon Buri south of Bangkok, Chiang Mai in the north, Khon Kaen in the northeast, and Song Khla in the south of Thailand. These cover around 7 million people, over 10% of the population.

In the beginning phase in 2019, the frequency plan for the DAB+ digital radio trial was planned to cover 10 major cities within eight provinces – Bangkok, Chiangmai, Kon Kaen, Nakorn Ratchasima, Sriracha, Pattaya, Prachaup Khiri Khan, Nakorn Si Thammarat, Songkla and Phuket. In 2021, the trial refocused on six major cities: Bangkok, Chiang Mai, Khon Kaen, Song Khla / Hat Yai and Chon Buri area (Sri Racha and Pattaya).

The objectives of the trial are to discover appropriate network parameters in different environments, to demonstrate interference-free audio and business models, and to introduce new data services on DAB+ including slideshows, data communication, emergency warning system (EWS), electronic programme guide (EPG), and pop-up services.

The initial trial started in April 2019 carried out in Bangkok and the immediate vicinity. The second trial was signed up in January 2021 for further development and in response to the emerging issues.

Today, the trial network consists of one DAB+ multiplex with capacity for up to 18 audio services (see Services on air) including the top ten most popular commercial channels in Bangkok plus six regional services and two data services.

In alignment with digitalization and digitization frameworks such as the Digital Economy and Society Development Plans (No. 1 (2016 - 2018) and No.2 (2018 - 2037)), digital transformation has been adopted in the First Thailand Broadcasting Master Plan B.E. 2555 – 2559 (2012-2016) and following the Second Broadcasting Master Plan B.E. 2563 – 2568 (2020 - 2025) as guidelines to enhance the standards of the broadcasting service and to increase access/options for people to continually receive services and necessary basic information throughout the nation.

The use of VHF radiofrequency for digital radio was as well collaboratively prescribed under the Spectrum Management Master Plan B.E. 2564 (2021) and its amendments. Thus, the roll-out of terrestrial digital radio has been continuously proceeding as one of the ultimate achievements since 2012. Today, the trial operation has been set as one of the key indicators of Strategy No.1 - the Development of Audio Broadcasting Service in Thailand - under the Second Broadcasting Master Plan.
