More flavor and features on radio chat

[Nnystyxx]

I kind of both like and dislike tg's feature to broadcast really BIG messages using a toggleable "high volume" mode. I feel like that shouldn't be spammable the way it is on TG though.

I definitely would be up for interference mechanics, especially if it meant solar flare communications just became shitty rather than me spam-transmitting to try and get to the random probability that I might actually send a message successfully, rather than having it eaten with no feedback

Knocking out/disturbing comms in an area sounds quite flavorful also
