Special approved 6 meters for CQWW VHF 2010.

This year 2010. This is a good news for Amateur radio in Thailand. NTC(Nation Telecomunication Commistion of Thailand) has authorised to use 50-54 Mhz in CQWW VHF contest 2010 or 48 hours on July 17-18, 2010.

"RAST had applied for permission to operate on six-metres during the CQWW VHF Contest this year following a suggestion by RAST Committee member John/Narissara, HS1CHB, during a committee meeting in May, 2010" news from http://www.qsl.net/rast/

6 meters has many hams have call a magic band because this is VHF band can communication in long distance.

First for this contest I must be make the new antenna for 6 meters band. I can't guess I can make the points in contest.
Last year made points very low becuase I have a little time to operate. This year hope to make contact to many hams in many countries.
