A5ØBOC: Thunder Dragon DX on the Low Bands

Hello fellow DXers!

As I occasionally do, this month I am turning over the keyboard to a guest writer. Adrian Ciuperca, KO8SCA will tell us all about the recent A5ØBOC DXpedition to Bhutan. Adrian, along with fellow teammates Champ Muangamphun, E21EIC; Franz Langner, DJ9ZB; and Max Van Rymenant, ON5UR were led by Zorro Miyazawa, JH1AJT, on this Bhutan adventure.
