Could you please clarify whether the eligibility period for obtaining a B license starts from the date the operating certificate is issued, or from the date the radio license is granted?
(There's also a minor issue: if we start counting from the date the certificate was issued, then my exam is only 4 days away from when I turn 6 months old. Can I still take the exam? Because the next exam is in December, and by then I won't be able to study for the entrance exam, so it will be June of next year. That's too long a wait, and I've also been wanting to try shortwave radio for a while.)
