The comms have neither authentication nor encryption. So at least on a technology level it is very possible to transmit.

I doubt they have robust enough authentication to determine whether you really are supposed to be speaking. Likely they won't believe you, but they will also start doubting, in general, messages sent over the channel. That means being less sure the actual authentic messages are to be believed.

It's more about disrupting their faith in the comm system, rather than about having them believe your falsehoods.
