  • KG4WBB:

    It is ridiculous to think that anyone would go into Korea under such difficulties. I support the removal from the DXCC as would anyone else that has any sense.

  • Jim N8RFT:

    I am not a DXer,but have to agree with KG4WBB. North Korea is a rogue nation,at best, and a totalitarian dictatorship in fact. They just imprisoned ANOTHER American for who knows what trumped up charges. Folks,I understand wanting those “hard to get” Calls,but please think about your freedom and your families.
