It’s a condition of licensed transmission on amateur radio frequencies that the operators are identifiable (give their official call sign as often as is practical) and that what is said is plainly understandable to anyone listening. You can’t do ‘anonymous code talk’ even if you do happen to have a licence. You can’t broadcast music, or do one-to-many messages except to setup one-to-one conversations (ie CQ or during club “nets”) - it’s not free, in fact it’s quite regulated.
