I think, perhaps, this is just one of those questions intended to make people aware of something.  You don't need this to safely operate, or even to operate without annoying people, and almost nobody sends QSL cards for VHF.

Welcome to the ham radio question pool development site.

Answer a question to give your feedback on how it could be improved, why it's not right, or why it should go.

You can vote questions up to indicate they're great, or down to indicate they should not be given.

To propose questions and have them discussed here, use the "Suggested" category within each element.

Feedback can be used by VECs to decide on questions to exclude, and will be forwarded to the NCVEC QPC on a regular basis.
