Thai Medium-Wave Stations


Here in Malaysia, many Asian stations fill the medium wave band. It is not uncommon to hear broadcasts originating from China, India, Indonesia, Kampuchea, Laos, Myanmar, Philippines, Sri Lanka, Taiwan and Vietnam. On rare occasions, transmissions from Europe, Middle East and Central Asia may be received too. Above all, Thailand stands out as the dominant broadcaster on the airwaves.

From the low to high end of the radio dial, Thai stations are spread pretty much across the band. Radio Thailand - Government Public Relations Department, Radio Thailand - National Education Radio, Thai Royal Police, various branches of Royal Thai Armed Forces, Agriculture, Meteorological and similar specialty stations operate on these frequencies. None or few are privately owned.

The Nakhon Sawan and Udon Thani transmitter sites are probably the more recognisable among short-wave enthusiasts, insomuch as   Babcock International, International Broadcasting Bureau and Radio Thailand utilise these facilities.

With this in mind, I set out to log as many Thai MW stations as possible, focusing primarily on Radio Thailand - Government Public Relations Department and
Radio Thailand - National Education Radio stations. While the list below is far from complete it should give an ideal as to the breadth  and content of Thailand's MW stations.

Interestingly, on the night of 22 May 2014, when the Royal Thai Armed Forces launched a coup d'état, regular programming ceased. Patriotic music and talk was synchronised on every station, making it obvious these were not only Thai stations but that something was amiss in the country. By the next evening,  their familiar format resumed as normal. 


Reception reports have been emailed to these stations listed below. To date, not one verification has been received. Thammasat University Radio acknowledged receipt of email, but failed to QSL. I suspect most Thai broadcasters have neither the interest to QSL, nor have any ideal what a Letter of Verification is. The only verifications received from Thailand have been from IBB in Udon Thani and Radio Thailand.

AsiaWaves is an excellent source for Thai stations, frequencies and  postal addresses:

Thai Government Organisation Directory lists names, positions and organisations related to Thai radio broadcasting. I found it quite useful in respect to postal addresses and email addresses.
