This is already old news but it is now official. Following the new national radio band plan published in november 2013 and signed by the president, several changes are noticeable. Band plan table starts on page 27.
Vietnamese HAM operators can now operate between 7100 KHz and 7200 KHz (in addition to 7000-7100 KHz previously) and also have the full 30 meters band allocated for amateur service (10100 KHz to 10150 KHz). 80 meters band is also allocated from 3500 to 3900 KHz (instead of 3800 KHz). More remarkably, the MF are also authorized on 472-479 KHz (600 meters) in addition to 1800-2000 KHz.
Please note that each band must be applied independently when you request your license.
