As it says. I suspect it's a bug, albeit a very minor one that is only noticeable if you actually switch the radio off, then later on check the computer and find a bunch of messages from whatever channel the radio was tuned in to.

Seems strange since the computer only records transcripts from the channel that it was set to, so I would expect that if the radio is off then it records nothing.

But like I said it doesn't really affect anything except adding extra spam to that channel's folder.
