The Thai National Broadcasting & Telecommunications Commission (NBTC) has invalidated a total of 140,000 amateur radio licences which had been expired for more than two years
Prior to the NBTC's action there had been over 248,000 amateur radio licenses in Thailand of which some 247,000 were for the Basic Entry Level licence which permits 100 watts on 28 MHz and 60 watts on 144 MHz.
A reason for so few upgrading is because of the lack of exam sessions. No exams were held to upgrade to Intermediate between 2004 and 2012.
The RAST also reported that former Vice President, Raymond Gerrard G3NOM/HS0ZDZ and former President Chamnong Bhirombhakdi HS1WB were both Silent Key.
