Good luck sending an e-mail that can’t be filtered and blocked or traffic analyzed, even if the content is encrypted.
As a minimum before trying, I would advise a peer to peer mix network (TOR, I2P). But repressive governments block those as well as they can, and may pay users a visit if they suspect something.
It is a thousand times more easy to send a secure electronic message then to broadcast an untraceable radio transmission to someone if any physical distance.
Any government they is locking down electronic communication that effectively would fine your radio based solution trivial to intercept and trace.
Or you could send an email.

It is 1000 times easier to get a message out online then in person but we still dress in furry suits and go stand outside buildings.
